To make the objectives， technical solutions， and advantages in the present invention clearer， the following further describes the implementation manners of the present invention in detail with reference to the accompanying drawings.

Embodiment 1

As a exemplary embodiment， before the acquiring the reverberation effect file corresponding to the reverberation effect meeting the environmental requirement from a prestored sampling reverberation database， the method further includes：

As an exemplary embodiment， after the reverberated wet sound is obtained， the method further includes：

As a exemplary embodiment， the playing back the obtained reverberated wet sound according to the playback request， includes：

In the method provided in the embodiment of the present invention， a sound segment to be processed is acquired， the acquired sound segment to be processed is converted into an original signal， so as to acquire a reverberation effect signal from a reverberation file corresponding to a reverberation effect meeting an environmental requirement， and the original signal and the reverberation effect signal are mixed to obtain a reverberated wet sound. A reverberated wet sound meeting an environmental requirement can be acquired without real-time computation， and therefore， resource consumption is relatively low， and efficiency of acquiring a reverberated wet sound is relatively high.

Embodiment 2

Because natural reverberated wet sounds exist in a small number， to acquire richer auditory materials and enhance effects of auditory experience of people， it is necessary to adopt a certain method to acquire a reverberated wet sound. For this， the embodiment of the present invention provides a method for acquiring a reverberated wet sound. Herein the method for acquiring a reverberated wet sound provided in the embodiment of the present invention is explained and described in detail with reference to the foregoing content in Embodiment 1.Referring to FIG. 2， the procedure of the method provided in this embodiment includes：

201： Acquire a sound segment to be processed， and convert the sound segment into an original signal.

The sound segment to be processed may be a dry sound segment， or may also be a reverberated wet sound segment. The sound segment to be processed is not specifically limited in this embodiment. The size of the sound segment to be processed may be 100k， 200k， 300k， and the like. The size of the sound segment to be processed is also not specifically limited in this embodiment.

The manner of acquiring the sound segment to be processed， includes， but is not limited to： acquiring a sound that is recorded by using a recording device such as a microphone， and using the acquired sound as the acquired sound segment to be processed.

Further， because a sound is produced from the vibration of an object， when the vibration of the object stops， the sound also stops. Therefore， to process the acquired sound segment， while the sound segment is acquired， the acquired sound segment needs to be converted into the original signal for storage. The original signal is a digital signal that has undergone no post processing. Specifically， the manner of converting the sound segment into the original signal， includes， but is not limited to， the following manners：

A first step： Convert a sound recorded by a microphone into a weak electrical signal.

For the first step， because a very thin and sensitive carbon film is provided in the microphone， when the sound propagates to the carbon film， the carbon film vibrates along with the sound； and because an electrode is connected below the carbon film， the carbon film comes into contact with the electrode during vibration； therefore， through recording of a sound by using a microphone， a sound signal may be converted into an electrical signal.

A second step： Amplify the weak electrical signal by using an amplification circuit to obtain an amplified electrical signal.

For the second step， an electrical signal obtained by using a microphone is relatively weak， and precision of processing the weak electrical signal is relatively low； therefore， to improve the precision of processing an electrical signal， the weak electrical signal needs to be amplified. Specifically， the amplification of the weak electrical signal includes， but is not limited to， amplification using a low noise operational amplification circuitry.

A third step： Convert the electrical signal into a digital signal.

For the third step， the conversion of the electrical signal into the digital signal includes， but is not limited to： selecting a sampling point from the electrical signal， and further converting the electrical signal into the digital signal by using a sampling theorem. The sampling theorem is： When a signal bandwidth is less than one half of a sampling frequency， a discrete sampling point may be used to fully represent a sampling signal.

202： Acquire， from a prestored sampling reverberation database， a reverberation effect file corresponding to a reverberation effect meeting an environmental requirement.

Because reverberation effect files corresponding to reverberation effects meeting different environmental requirements are stored in the sampling reverberation database， a corresponding reverberation effect may be added to the sound segment to be processed by using a reverberation effect file corresponding to a reverberation effect. Therefore， to enable the acquired sound segment to meet an environmental requirement during playback， after the sound segment is acquired， a reverberation effect file corresponding to a reverberation effect meeting an environmental requirement needs to be acquired from the prestored sampling reverberation database， so that in subsequent steps， the sound segment to be processed may be processed according to the reverberation effect file that corresponds to the reverberation effect meeting the environmental requirement and is acquired from the prestored sampling reverberation database. The reverberation effect file corresponding to the reverberation effect may be a data file that can add the corresponding reverberation effect to the sound segment to be processed.

Further， because the acquisition of the reverberation effect file corresponding to the reverberation effect meeting the environmental requirement from the prestored sampling reverberation database is a key to the processing of the acquired sound segment to be processed in subsequent steps， before the reverberation effect file corresponding to the reverberation effect meeting the environmental requirement is acquired from the prestored sampling reverberation database， the reverberation effect file needs to be generated first. To enable the reverberation effect of the processed sound segment to better meet the environmental requirement， a reverberation sampling method is adopted in this embodiment to generate a reverberation effect file， that is， a corresponding reverberation effect file is generated according to a reverberation effect that is obtained through sampling from a practical physical reverberation space and meets each environmental requirement.

Further， because the generated reverberation effect file is obtained by performing digital processing on a reverberation effect that is obtained through sampling from a practical physical reverberation space and meets each environmental requirement， the acquiring the reverberation effect file is acquiring a reverberation effect file corresponding to a reverberation effect that is obtained through sampling from a practical physical reverberation space and meets each environmental requirement. Specifically， the manner of acquiring the reverberation effect file corresponding to the reverberation effect that is obtained through sampling from a practical physical reverberation space and meets each environmental requirement includes， but is not limited to， the follows steps：

A first step： Perform precise measurement and sampling on different practical physical reverberation spaces to obtain reverberations corresponding to different environments.

To make it easy to understand the foregoing process of performing precise measurement and sampling on different practical physical reverberation spaces to obtain reverberations corresponding to different environments， a specific example is taken for detailed explanation and description below.

For example， collect a reverberation from a teacher′s desk to a student′seat in a classroom. A speaker may be placed at the position of the teacher′s desk， and a microphone is placed at the position of the student. An impulse is played in the speaker for every sentence the teacher says， and the microphone performs recording according to the received impulse， and a recorded sound is the reverberation from the teacher′s desk to the student′seat in the classroom.

A second step： Convert an obtained reverberation corresponding to a different environment into a data form for storage， so as to obtain a reverberation effect file.

For the second step， for ease of the subsequent application of the collected reverberation， the obtained reverberation corresponding to the different environment needs to be converted into a data form and stored in a file this embodiment. The file storing the data is the reverberation effect file.

A third step： Acquire the reverberation effect file， and use the acquired reverberation effect file as a reverberation effect file that is obtained through sampling from a practical physical reverberation space and corresponds to a reverberation effect meeting each environmental requirement.

Further， because a reverberation effect file that is obtained through sampling from a practical physical reverberation space and corresponds to a reverberation effect meeting each environmental requirement continues to be applied during subsequent processing of the acquired sound segment to be processed， the reverberation effect file obtained through sampling may be stored in the sampling reverberation database， so that during subsequent processing of the sound segment to be processed， a reverberation effect file corresponding to a reverberation effect meeting an environmental requirement may be directly acquired from the sampling reverberation database. The manner of storing the sampling reverberation database includes， but is not limited to， storing the sampling reverberation database in a storage medium such as a hard disk and an optical disc.

203： Acquire a reverberation effect signal according to the reverberation effect file.

Reverberation effect data is stored in the reverberation effect file， and the reverberation effect data is imported into a signal processing apparatus， so that the reverberation effect signal corresponding to the reverberation effect may be acquired. Therefore， the reverberation effect file corresponding to the reverberation effect meeting the environmental requirement may be acquired from the prestored sampling reverberation database for processing to acquire the reverberation effect signal. The signal processing apparatus includes， but is not limited to， an oscillograph and a reverberation effects unit.

204： Mix the original signal with the reverberation effect signal to obtain a reverberated wet sound.

To provide the sound segment to be processed with the reverberation effect meeting the environmental requirement， in the method provided in this embodiment， the original signal converted from the sound segment to be processed needs to be mixed with the reverberation effect file corresponding to the reverberation effect meeting the environmental requirement. The original signal and the reverberation effect signal are mixed to obtain the reverberated wet sound meeting the environmental requirement.

Specifically， the mixing the original signal with the reverberation effect signal includes， but is not limited to， in the follows manners：

First， input the acquired original signal and reverberation effect signal into the signal processing apparatus， and the signal processing apparatus may be used to acquire a waveform of the original signal a waveform of the reverberation effect signal.

Second， superimpose the waveform of the original signal and the waveform of the reverberation effect signal that are acquired by the signal processing apparatus to obtain a superimposed waveform.

Third， use the superimposed waveform as a waveform corresponding to the processed reverberated wet sound， store data corresponding to the obtained waveform， and a playback apparatus plays back the stored data to obtain the reverberated wet sound.

The superimposing the waveform of the original signal and the waveform of the reverberation effect signal that are acquired by the signal processing apparatus includes， but is not limited to， superimposing the waveform of the original signal and the waveform of the reverberation effect signal by using a method of convolution computation. Specifically， the waveform of the original signal may be represented by using one wave function， the waveform of the reverberation effect signal may also be represented by using one wave function， and by using convolution computation， the wave function of the original signal and the wave function of the reverberation effect signal may be synthesized into one wave function； therefore， the waveform of the original signal and the waveform of the reverberation effect signal may be superimposed by using convolution computation. Convolution computation is an important operation in analytical mathematics， and by using convolution computation， two functions are synthesized into a third function. For example， if h (x) ＝ (f*g) (x) ， h (x) is a convolution of f and g.

Here， a reverberated wet sound meeting an environmental requirement may be obtained by using the foregoing method， and to play back the obtained reverberated wet sound， the method provided in this embodiment further includes， but is not limited to， a step of receiving a playback request for the reverberated wet sound， so as to further play back the obtained reverberated wet sound according to the playback request. The manner of receiving the playback request for the reverberated wet sound includes， but is not limited to， receiving a playback request that is sent in a form such as a message and a notification. The content of the playback request includes， but is not limited to， playback time of the reverberated wet sound， and the volume of a current playback environmental requirement.

Specifically， the playing back the obtained reverberated wet sound according to the playback request includes， but is not limited to：

acquiring the volume meeting the current playback environment； and

The playback request carries the volume meeting the current playback environmental requirement， and therefore， the volume of the reverberated wet sound may be adjusted according to the volume meeting the current playback environmental requirement carried in the playback request， so as to enable the played back reverberated wet sound to meet current environmental requirement. Specifically， during the adjustment of the volume of the reverberated wet sound according to the volume meeting the current playback environmental requirement carried in the playback request， if the volume meeting the current playback environmental requirement carried in the received playback request is higher than the volume of the acquired reverberated wet sound， turn up the volume of the acquired reverberated wet sound， and Ifthe volume meeting the current environmental requirement carried in the received playback request is lower than the volume of the acquired reverberated wet sound， turn down the volume of the acquired reverberated wet sound.

For the foregoing process， for ease of understanding， a specific example is taken for detailed explanation and description below.

For example， the volume of the acquired reverberated wet sound is set to 100％. When the volume meeting the current playback environmental requirement carried in the received playback request is 70％， turn down the volume of the acquired reverberated wet sound to 70％， so as to further play back the reverberated wet sound at 70％of the volume of the acquired reverberated wet sound. When the volume meeting the environmental requirement carried in the received playback request is 120％， turn up the volume of the acquired reverberated wet sound to 120％， so as to further play back the reverberated wet sound at 120％of the volume of the acquired reverberated wet sound.

Certainly， if a sound needed in the current environment is a sound segment to be processed， to play back the sound segment to be processed， the method provided in this embodiment further includes a step of receiving the playback request for playing back the sound segment to be processed， so as to further play back the sound segment to be processed according to the received playback request. Specifically， during the playback of the sound segment to be processed according to the received playback request， if the volume meeting the current playback environment carried in the received playback request is higher than the volume of the sound segment to be processed， turn up the volume of the sound segment to be processed， and ifthe volume meeting the current environment carried in the received playback request is lower than the volume of the sound segment to be processed， turn down the volume of the sound segment to be processed.

Optionally， the touch sensitive surface 131 may include two parts： a touch detection apparatus and a touch controller.
