The earphone body 11 may be a Bluetooth earphone or a hearing aid. When the sound source is far away from the earphone user, the charging box 12 may be placed near the sound source, and the microphone module 14 may pick up the sound, and then the audio may be transmitted to the earphone body 11 through the wireless connection between the first wireless transmission chip and the second wireless transmission chip 13. Audio transmission through a wireless transmission chip has the characteristics of low latency and anti-interference, wherein the transmission mode of the wireless transmission chip may be Bluetooth, wifi, UWB (English name: Ultra Wide Band, Chinese name: wireless carrier communication technology), NFC (English name: Near Field Communication, Chinese name: short-range wireless communication technology), ZIGBEE (English name: ZigBee Technology, Chinese name: ZigBee Technology), 3G, 4G or 5G transmission, and a module for implementing a corresponding transmission mode is provided in the wireless transmission chip. Specifically, one or several corresponding transmission modules may be selected according to different usage scenarios and provided on the wireless transmission chip, so as to ensure that the listener can hear the sound emitted by the sound source in real time and clearly at a position far away from the sound source, thereby improving the user experience.

Moreover, the microphone module 14 is disposed on the top of the housing 121. By disposing the microphone module 14 on the top of the housing 121 or near the top of the housing 121, it is possible to better receive sounds from all directions compared to installing the microphone module 14 on the side wall or bottom wall of the housing 121. It should be noted that the number of microphone modules 14 can be at least two, and at least two microphone modules 14 are disposed on the top of the housing 121, which enhances the sound receiving capability of the earphone set 1 and brings a better listening experience to the user.

In addition, the microphone module 14 is disposed on the side wall of the housing 121. By disposing the microphone module 14 on the side wall of the housing 121, the focus is on collecting the sound in the direction facing the microphone module 14, and the ability of the microphone module 14 to collect the sound on that side is strengthened.

Furthermore, the earphone body 11 also includes an earphone control key, which is electrically connected to the first PCB board, and is used to control the microphone module 14 through the first PCB board, the first wireless transmission chip, the second PCB board 122 and the second wireless transmission chip 13. By setting the earphone control key, the user can remotely control the microphone module 14 to be turned on or off through the earphone control key, which brings a better user experience.

In addition, the voice information includes human voice information and noise information. A noise processing module is also provided on the second PCB board 122. The microphone module 14 is used to send the human voice information and noise information to the noise processing module, and the noise processing module is used to filter out the noise information. The noise processing module processes the voice information through an algorithm, thereby filtering out the noise information, so that the sound heard by the user or the sound of the audio file stored in the memory is clearer, thereby improving the user's experience.

In addition, a memory is also provided on the charging box 12 so that the voice information picked up by the microphone module 14 can be stored in the memory.

Moreover, the charging box 12 also includes a second sound unit, which is installed on the housing 121 and is electrically connected to the second PCB board 122. By adding the second sound unit, the second sound unit can be used to play audio files stored in the memory. It should be noted that the user can control the second sound unit to play audio files or pause audio files through the touch display; the user can also control the second sound unit through a mobile terminal through a wired connection or wireless transmission.

In addition, the earphone kit 1 can be connected to a mobile terminal, and the mobile terminal is provided with a third wireless transmission chip, and the mobile terminal is used to control the microphone module 14 through the third wireless transmission chip, the second wireless transmission chip 13 and the second PCB board 122. The user can adjust the directivity of the microphone module 14 through the APP of the mobile terminal, so that the user can collect the sound of one person, multiple people or multiple ranges by adjusting the directivity of the microphone module 14. It should be noted that the user can also control the recording, stopping, pausing, playing, selecting and other operations of the audio recording through the APP of the mobile terminal.

As shown in FIG2 , the housing 121 is provided with a through hole 15 for exposing the microphone module 14, and the charging box 12 further includes a dustproof net 16, which is embedded in the through hole 15. The through hole 15 is provided to facilitate the microphone module 14 to pick up sound, and the dustproof net 16 is provided to reduce the dust entering the housing 121 from the through hole 15, thereby reducing the dust entering the microphone module 14 from the sound hole of the microphone module 14, and avoiding excessive dust entering to affect the sound quality of the microphone module 14 or block the sound hole. It should be noted that the microphone module 14 is located on the inner side of the housing 121.

Furthermore, the charging box 12 further includes a waterproof breathable membrane 17, which covers one end of the through hole 15 facing the inside of the housing 121 to prevent water from entering the housing 121 from the through hole 15. By providing the waterproof breathable membrane 17, water is prevented from flowing into the housing 121 from the through hole 15 to corrode the second PCB board 122 or affect the normal use of the microphone module 14. At the same time, the waterproof breathable membrane 17 allows air to pass through, so it does not affect the microphone module 14 from picking up sound signals.
