Description

in-ear headset

technical field

The utility model relates to audio equipment technology, in particular to an in-ear headset technology.

Background technique

In-ear headsets are equipped with a speaker and a contact microphone in the casing, and a sound hole is opened on the casing, so that the sound from the speaker can be transmitted to the ear canal. The contact microphone is in contact with the muscle tissue of the human ear canal, picking up The vibration of the skull and muscle tissue when a person makes a sound is converted into an electrical signal, thereby realizing voice transmission. However, because the muscle tissue of the ear canal is very soft, it is not easy to converge when vibrating, especially low-frequency vibrations can cause long-term tremors in the muscle tissue, so the vibration waves in the muscle tissue will have a superimposed effect similar to echoes in the time domain, causing voice signals The turbidity and the decrease of speech intelligibility. In addition, because the muscle tissue is very soft, it has a greater attenuation to high-frequency vibrations, which is another reason for the low voice clarity of the ear canal contact microphone.

Utility model content

Aiming at the defects in the above-mentioned prior art, the technical problem to be solved by the utility model is to provide an in-ear headset with high voice clarity.

In order to solve the above-mentioned technical problems, an in-ear headset provided by the utility model includes a casing, an earplug, a loudspeaker and a contact microphone respectively installed in the casing;

The casing is composed of an inner half shell and an outer half shell, and a sound hole is opened on the casing, so that the sound in the casing can be transmitted to the outside of the casing, the inner end of the casing is cylindrical, and a a slot into which the contact microphone is inserted with an interference fit;

The earplug is composed of a soft earcap and a soft inner tube fixed in the earcap, and the inner end of the casing is inserted into the inner tube of the earplug in an interference fit manner;

It is characterized in that a soft O-ring is placed on the earplug, and the inner end of the casing passes through the ring center of the O-ring.

Further, the O-ring is sleeved on the inner tube of the earplug, and is interference fit with the inner tube of the earplug.

Further, the O-ring is integrally formed with the inner tube of the earplug.

Further, the O-ring is integrally formed with the ear cap of the earplug.

The in-ear headset provided by the utility model, due to the existence of the O-ring, the muscle tissue gap between the skull and the O-ring is narrowed and compressed, so the muscle tissue there is not easy to tremble naturally, so that the vibration can quickly converge, When the high-frequency vibration of the skull passes through this part of the muscle tissue, the attenuation will also be reduced, so that the vibration fluctuations transmitted into the contact microphone are greatly reduced, whether it is time-domain superposition effect or high-frequency attenuation, thereby greatly improving the clarity of speech.

detailed description

The embodiments of the present utility model are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present utility model. All similar structures and similar changes of the utility model should be included in the protection of the utility model. Scope, the comma in the utility model all represents and the relation.

As shown in Figures 1-2, an in-ear headset provided by the first embodiment of the present invention includes a casing, earplugs, and a speaker 2 and a contact microphone 3 respectively installed in the casing;

The casing is formed by joining the inner half casing 12 and the outer half casing 11, and a sound hole 13 is provided on the casing, so that the sound in the casing can be transmitted to the outside of the casing, and the inner end 121 of the casing is cylindrical ( The end toward the inside of the ear is the inner end, and the end toward the outside of the ear is the outer end), a slot is arranged in the casing, and the contact microphone 3 is inserted into the slot in an interference fit manner;

The earplug is composed of a soft ear cap 42 and a soft inner tube 41 fixed in the ear cap 42, and the inner end 121 of the casing is inserted into the inner tube 41 of the earplug in an interference fit manner;

It is characterized in that: a soft O-ring 5 is sheathed on the inner tube 41 of the earplug, the O-ring 5 is in interference fit with the inner tube 41 of the earplug, and the inner end 121 of the casing passes through the O-ring 5 The center of the ring, due to the interference fit between the O-ring and the inner tube of the earplug, is not easy to move relative to the earplug, and has high reliability.

When the first embodiment of the utility model is in use, the inner end of the casing is inserted into the ear canal, the output sound of the speaker is input into the ear canal through the sound hole on the casing, and after the inner end of the casing is inserted into the ear canal, the ear cap of the earplug sticks Tighten the musculature 6 on the inner wall of the ear canal. Due to the existence of the O-ring, the ear canal musculature 6 is compressed at the position of the O-ring, so that the muscular tissue gap between the skull 7 and the O-ring 5 is reduced and compressed, so The muscle tissue is not easy to vibrate naturally, so that the vibration can be quickly converged. At the same time, because the muscle tissue is compressed, the attenuation of the high-frequency vibration of the skull will be reduced when it passes through this part of the muscle tissue. Both domain superposition effect and high-frequency attenuation are greatly reduced, which greatly improves the clarity of speech. Since the O-ring is round and soft, there is no foreign body sensation when the user wears it, and the inner end of the case is in the ear canal Turning the angle at will will not cause changes in voice quality, and it is very convenient to use.

As shown in Figure 3, the difference between the second embodiment of the utility model and the first embodiment is that the O-ring 205 in the second embodiment is integrally formed with the inner tube 241 of the earplug. The shape ring is integrally formed with the inner tube of the earplug, and will not move relative to the earplug, and has higher reliability than the first embodiment.

As shown in Figure 4, the difference between the third embodiment of the utility model and the first embodiment is that the O-ring 305 in the third embodiment is integrally formed with the ear cap 342 of the earplug, and the third embodiment of the utility model is due to O The ring is formed integrally with the ear cap of the earplug, and will not move relative to the earplug, and has higher reliability than the first embodiment.
