[0024] Working principle: The first sound channel 2 is used to connect to the tinnitus rehabilitation music source. When the patient goes out and carries electronic devices such as mobile phones, they can connect to the headphone body 1 through the Bluetooth receiving module 20 to transmit the tinnitus rehabilitation music in the device to the headphone body 1. If the patient is in a scenario without external devices, such as when exercising outdoors, the rehabilitation music stored in the built-in storage module 18 can be used. The patient can import the appropriate tinnitus rehabilitation music from the computer into the built-in storage module 18 in advance through the Type-C data transmission interface 6. If the import process is interrupted, the transmission can be resumed using the breakpoint resume function when reconnecting. The first amplifier 19, the second amplifier 24, the first filter 21 and the second filter 25 amplify and filter the received signal. The first sound unit 23 converts the processed signal into sound output. The second sound channel 3 is used to connect to an external sound source. The microphone 28 collects ambient sound signals in real time. The wireless communication module 22 receives wireless signals such as telephone signals. The second signal processing module processes the received signals. The second sound unit 27 converts the processed signals into sound output. The patient can adjust the volume of the output sound of the first sound unit 23 and the second sound unit 27 respectively through the volume adjustment unit 17 according to the actual scene. For example, in a quiet library, the volume of the external sound source can be appropriately reduced to highlight the tinnitus rehabilitation music. In a noisy street, the volume of the external sound source can be increased to ensure that the external sounds can be heard clearly. The patient can turn the headphones on and off by pressing the control button 4. Pressing and holding the control button 4 can switch between Bluetooth transmission playback and built-in storage playback modes. Through specific combination button operations, the patient can control the playback, pause, previous track, and next track of the music in the built-in storage module 18. Because patients have different ear shapes, the size and dimensions of the ear loops 3 required are also different. Different ear loops 3 need to be replaced according to the patient's needs. When replacing the ear loop 3, press the two buckles 5. The buckles 5 compress the second spring 33. When the buckles 5 retract into the slot 32, the buckles 5 no longer restrict or block the connecting block 31. Since the first spring 29 is in a compressed state, the first spring 29 returns to its original state. The connecting block 31 is pushed out of the connecting seat 10 through the spring plate 30. Then, pull the ear loop 3 to complete the disassembly. When installing a new ear loop 3, the principle is the same. Push the two buckles 5 into the slot 32 and insert the connecting block 31 into the connecting seat 10. When the buckles 5 reach the position of the slot 32 of the connecting seat 10, the second spring 33 returns to its original state, so that the buckles 5 pop out to complete the installation of the new ear loop 3, which is suitable for different patients.

[0025] The channel switching module 7 is equipped with a physical switch 71 and a virtual switch button 72. When the patient needs to focus on listening to external sounds, such as during a meeting, they can switch to the second sound channel mono mode by toggling the physical switch 71. In this mode, the mixing module 4 only plays the external sounds output by the second sound unit 27. If the patient wants to undergo tinnitus rehabilitation treatment in a quiet environment, they can switch to the first sound channel mono mode, playing only tinnitus rehabilitation music. Under normal circumstances, the dual-channel mode is maintained, mixing the tinnitus rehabilitation music with the external sound source. In addition, the patient can also switch the sound channel mode by clicking the virtual switch button 72 on the mobile application that comes with the headphones. The playback control module 8 is connected to the built-in storage module 18 and the first signal processing module 22. Users can create multiple playlists in the mobile application, such as "Soothing Rehabilitation Music" and "Invigorating Rehabilitation Music," to categorize and store tinnitus rehabilitation music of different styles. During playback, users can select random playback, sequential playback, or loop playback modes. The playback control module 8 executes the corresponding operation according to the user's selection and also has a playback memory function, automatically resuming playback from the last stopped position upon the next power-on.
