Problems solved by technology

[0003] However, the working principle of the bone conduction mobile terminal is to convert electrical energy into mechanical vibration, and complete the transmission of sound through mechanical vibration, which requires relatively large power consumption, high power consumption, and reduces the battery life of the mobile phone; while the receiver mobile terminal uses The principle of the electromagnetic effect of the inductance, even if the changing audio signal is fed into the voice coil, the voice coil is placed in the magnetic gap of a permanent magnet magnetic circuit, the changing electromagnetic field force (Lorentz force) generated by the voice coil due to the changing current ) is driven to vibrate up and down, and drives the diaphragm to drive the front and rear air to generate sound waves, which is easily disturbed by the external environment, especially in noisy places, and the efficiency of answering calls is particularly low
[0004] Therefore, the above two mobile terminals can no longer meet the call needs of users in different scenarios
