By way of example and not limitation, the present embodiment places one microphone 30 and one receiver 40 on each of the armsets 20, i.e., the entire headset contains two microphones 30 and two receivers 40. However, the present invention is not limited thereto, and in other embodiments, the whole earphone may also include only one microphone 30 and one receiver 40, in which case, the microphone 30 and the receiver 40 may be arranged on the same earphone arm assembly 20, or may be separately arranged on two earphone arm assemblies 20, and in order to satisfy the weight balance of both sides of the earphone, one microphone 30 and one receiver 40 may be replaced by two configuration blocks (not shown) having the same shape, size, weight, and arrangement position as those of the microphone 30 and the receiver 40, so that the earphone as a whole has two microphones 30 and two receivers 40.

In the present embodiment, when the earhook 22 is worn on the human ear, the receiver 40 is placed at the mastoid position of the human ear, and the transmitter 30 is placed at the zygomatic bone position of the human ear. When the ear hook is specifically implemented, the ear hook can adopt a structure with hard inside and soft outside, the ear hook 22 is arc-shaped and is matched with the shape of the outer contour of the human ear, namely the ear hook 22 can be designed according to the size of the outer contour of the human ear, so that the ear hook 22 can be hung on the human ear and has certain clamping force on the human ear; the relative positions of the receiver 40 and the microphone 30 may be set according to the positional relationship of the zygomatic position of the human ear and the mastoid position, so that the receiver 40 is naturally placed at the mastoid position when the microphone 30 is placed at the zygomatic position.

It should be noted that, as a preferred embodiment, the purpose of placing the microphone 30 at the cheekbone position of the ear in this embodiment is to make the cheekbone position smoother so as to make the microphone 30 fit the cheek more closely, and to make the microphone 30 close to the cheekbone so as to be more beneficial to the transmission of speaking vibration and improve the microphone effect. Meanwhile, the receiver 40 is arranged at the mastoid position of the human ear, the mastoid position is arranged at the back of the human ear and a pit naturally exists, the receiver 40 is arranged at the mastoid pit and is shielded by the human ear, a good sealing sound insulation effect is naturally formed, the privacy is good, and the voice playing is not easy to eavesdrop. Of course, in other embodiments, the positions of the microphone 30 and the receiver 40 can be mutually reversed, that is, the receiver 40 is disposed on the end of the ear hook 22 away from the earphone arm 21, and the microphone 30 is disposed on the end of the earphone arm 21 away from the neck pendant 10.

In addition, in the present embodiment, a battery is disposed in one of the earphone arms 21, and a wireless communication module is disposed in the other earphone arm 21, that is, a battery is disposed on one side, and a wireless communication module is disposed on the other side, and since the receiver 40 and the transmitter 30 on both sides of the earphone both need to be powered by the battery and need to communicate with the wireless communication module at the same time, a wire (not shown in the drawing) is disposed in the neckphone 10, and the electric devices disposed on the two earphone arm assemblies 20 are communicated with each other through the wire in the neckphone 10, and the wire may include multiple wires, for example, the battery is electrically connected with the receiver 40 and the transmitter 30 on the other side through one set of wires in addition to the receiver 40 and the transmitter 30 on the same side, and the wireless communication module is electrically connected with the receiver 40 and the transmitter 30 on the other side through another set of wires in addition to the receiver 40 and the transmitter 30 on the same side. The battery specifically can be cylindric lithium cell, wireless communication module specifically can be wireless bluetooth chip, through setting up the bluetooth, can realize the thing of earphone and mobile device and ally oneself with, the user can control the earphone through mobile terminal, like volume control.

Specifically, the microphone 30 includes a first housing 31, a first housing cover 32 covering the first housing 31, and a microphone unit 33 and a first rigid elastic sheet 34 disposed in a first accommodating cavity 30a enclosed by the first housing 31 and the first housing cover 32, where the first rigid elastic sheet 34 is fixedly disposed on a side of the microphone unit 33 close to the first housing cover 32. The vibration that the user spoke and produced transmits for microphone monomer 33 through first cap 32 and first casing 31 to convert the sound of speaking into the signal of telecommunication and outwards send through wireless communication module, first rigidity shell fragment 34 can vibrate along with microphone monomer 33, thereby improves vibration transmission effect, improves send voice quality. The receiver 40 includes a second housing 41, a second housing cover 42 covering the second housing 41, and a speaker unit 43 and a second rigid elastic sheet 44 which are disposed in a second accommodating cavity 40a enclosed by the second housing 41 and the second housing cover 42, wherein the second rigid elastic sheet 44 is fixedly disposed on one side of the speaker unit 43 close to the second housing cover 42, and when the wireless communication module receives an electrical signal, the electrical signal is sent to the speaker unit 43, so that the speaker unit 43 generates a vibration signal. In this embodiment, the second rigid elastic sheet 44 is further fixed on one side of the single speaker body 43 close to the second housing cover 42, and the second rigid elastic sheet 44 can vibrate together with the single speaker body 43, so as to improve the vibration transmission effect and improve the voice playing tone quality. In the implementation, the parts of the microphone 30 and the receiver 40 can be fixed by gluing.

Similarly, the second accommodating cavity 40a is also filled with a second soft adhesive (not shown), and the speaker unit 43 and the second rigid elastic piece 44 are wrapped and fixed by the second soft adhesive, which also solves the "stethoscope effect" of the receiver 40. The "stethoscope effect" is a phenomenon in which fine vibration signals are picked up by the bone conduction microphone 30 and the receiver 40 to generate noise due to air friction or touching of the outer surface of the earphone when the earphone is worn or touched.

It should be noted that, since the shape of the casing of the microphone 30 is directly related to the vibration transmission, the size of the vibration signal can be adjusted by adjusting the shape and size of the casing, so as to adjust the acoustic characteristics (frequency response and/or distortion) and achieve better speech intelligibility of the microphone. Therefore, in order to have the best acoustic characteristics, the present embodiment also performs experimental analysis on the outer shapes of the housing of the microphone 30 and the mating first rigid elastic piece 34 thereof, as shown in fig. 6-10, five shapes of a square, a rectangle, a circle, an oval racetrack shape and a fan shape are designed for the outer shapes of the housing of the microphone 30 (including the first housing 31 and the first housing cover 32) and the mating first rigid elastic piece 34 thereof, and the experimental analysis is performed in cooperation with three dimensions, namely a standard area, a small area and a large area (relative), respectively manufacturing corresponding engineering prototypes for each case, and repeatedly performing frequency response index test comparison analysis on the engineering prototypes.
