Incoming call prompting device with signal detection and identification function

A portable electronic device holding device, in particular, an incoming call prompting device with signal detecting and identifying function.

Due to the progress of the times and the improvement of living standards, portable electronic devices such as mobile phones have been widely used by the public. Currently, mobile phones generally receive two kinds of prompting methods when receiving messages: ringing and vibration. The ringing of the mobile phone has two kinds of ringtones and music, which has obvious hint effect. The vibration mode can also play a prompt effect when it is carried around.

However, due to habit problems or considering the electromagnetic radiation of mobile phones, most people do not carry mobile phones, such as office workers in the office will put the phone on the desk, or at home will put the phone on the table, and some people will Put the phone in the phone holder or the phone holder, but if the user is not in the vicinity of the portable electronic device such as a mobile phone, because the volume of the ringing is limited, or the mobile phone is set to the vibration mode, it is not carried around. The hint effect itself has no effect.

Since the mobile phone needs to generate a ringing or vibrating alert effect when the incoming call is made, and the mobile phone charger or the mobile phone holder only has the charging or holding function, even when the user returns to the vicinity of the mobile phone, the caller cannot be known, such as an incoming call. The nature of being very urgent or requiring immediate response will cause confusion or even irreversible loss to the user. Therefore, it is necessary to have an incoming call prompting device with signal detection and identification function.

Since the mobile phone can only send the call prompt effect when the user is nearby and just has an incoming call, and the mobile phone holder and the mobile phone charger can only be used to hold the mobile phone or charge the mobile phone without the call prompt function.

In addition, it is necessary to consider the call is usually urgent and needs immediate reply. Nature, and the newsletter is relatively of a message or notification nature, so it is necessary to develop a call alert device that can detect and identify signals, so that the user knows that there is a missed call or a short message to be read. If you do not receive a call, you will reply immediately. If it is a newsletter, you can read it later or reply.

The call prompting device with the signal detecting and recognizing function of the present invention comprises a signal capturing unit for sensing and capturing a radio signal and transmitting the radio signal; a signal detecting unit electrically connected to the signal detecting unit The signal acquisition unit is configured to receive the radio signal to detect whether the frequency of the radio signal is within a predetermined frequency range, and further determine whether to continue transmitting the radio signal; and a signal amplification unit electrically connected to the signal The signal detecting unit receives the radio signal and amplifies the radio signal, and transmits the amplified radio signal; a signal conversion unit is electrically connected to the signal amplifying unit to receive the amplified signal The radio signal converts the amplified radio signal into a voltage signal; an arithmetic unit is electrically connected to the signal conversion unit to receive the voltage signal, and converts a time domain signal of the voltage signal by using a Fourier transform operation Is a frequency domain signal, and transmits the frequency domain signal and the time domain signal; The identification unit is electrically connected to the operation unit to receive the frequency domain signal and the time domain signal, and determine the radio signal as an incoming signal or a wireless transmission signal according to the amplitude of the frequency domain signal, and according to the time domain The period of the signal determines whether the radio signal is an incoming call signal or a caller message. At least one prompting unit is electrically connected to the signal identifying unit to receive and respond to the incoming call signal, the incoming call message or the wireless transmission signal sent by the signal identifying unit to generate a prompt corresponding to the incoming call signal, the incoming call message or the wireless transmission signal effect.

The effect of the present invention enables the portable electronic product holding device to have a signal detecting and recognizing function and a corresponding prompt function according to the signal identification result, so that the user knows that there is a missed call or a short message to be read, and Provides a bold and continuous reminder effect to the user.
