Description

Technical Field

[0001] The utility model relates to the technical field of wireless earphones, in particular to a wireless pressure-sensitive earphone based on the Hall effect. Background Art

[0002] With the development of in-ear headphones and users' demand for diversified interactive functions, higher requirements are placed on the design of buttons for realizing the interactive functions of headphones. For wireless headphones, the realization of their interactive functions usually requires users to control them in the form of touch headphones. With the rise of TWS (Ture Wireless Stereo) headphones, assembly space for functional elements such as in-ear detection and sound pickup must be reserved in the headphone shell, and high assembly accuracy is required for each functional module; therefore, for the structural design of the interactive function module, it is necessary to reduce assembly errors and enhance signal detection while meeting the requirements of basic interactive control and limited assembly space to achieve normal operation.

[0003] When using wireless pressure-sensing headphones, earwax inside the user's ear is easily attached to or even blocked in the dust-proof net inside the sound outlet, thereby blocking the sound outlet of the headphone. This will not only affect the sound quality emitted from the headphone, but also affect the user's hearing. The existing cleaning method can only be cleaned from the outer end of the dust-proof net plate, which can easily cause earwax to enter the headphone through the mesh of the dust-proof net plate. After long-term use, the headphone will be filled with earwax, affecting normal use. Therefore, it is necessary to design a wireless pressure-sensing headphone based on the Hall effect.

When the touch area 2 is pressed, the touch area 2 is deformed, so that the position of the magnet 18 changes. According to the Hall effect principle, the Hall sensor chip 6 detects the change of the output voltage signal and controls the play, pause and other functions of the headset through the cooperation of the microcontroller and the main control Bluetooth chip on the main control circuit board 5. (The microcontroller and the main control Bluetooth chip are not drawn, but the microcontroller, the main control Bluetooth chip, the magnet 18, the Hall sensor chip 6, the main control circuit board 5 and the touch area 2 are all existing public technologies).

[0021] Further, the rotating mechanism includes a rotating ring 9, a gear ring 10, a gear 15, a first rotating shaft 12, a second rotating shaft 16, a first bevel gear 13 and a second bevel gear 14.
