Abstract

The embodiment of the invention provides a mobile terminal, relates to the technical field of communications, and solves the problem that the mobile terminal has an obvious sound leak phenomenon during a call. The mobile terminal comprises a rear cover and a display module installed on the rear cover; a telephone receiver and a circuit board are installed in a containing space which is formed between the rear cover and the display module; the display module is provided with a first opening on the position corresponding to the telephone receiver, and a first sound wave generated by the telephone receiver is propagated through the first opening to the outside; the circuit board is located at one side of the telephone receiver away from the display module, and a leak hole is arranged on the circuit board; the rear cover is provided with a second opening, and a second sound wave generated by the telephone receiver is propagated to the outside orderly through the leak hole and the second opening; by setting the position parameters of the first opening and the second opening, an acoustic short-circuiting effect is produced when the first sound wave meets the second sound wave; and the sound wave, generated by the telephone receiver, propagated via the first opening is a first sound wave, and propagated via the second opening is a second sound wave.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technologies, and in particular, to a mobile terminal. Background technique [0002] The mobile terminal has a calling function, which brings a lot of convenience to the user's life. [0003] A receiver is installed on the top of the mobile terminal. During a call, the receiver converts the amplified electrical signal into a sound signal. Its working principle is that the changing audio electrical signal is fed into the voice coil, and the voice coil is placed in the magnetic gap of a permanent magnet magnetic circuit. , the voice coil vibrates up and down driven by the changing electromagnetic field force (Lorentz force) generated by the changing current, and drives the diaphragm to drive the front and rear air to generate sound waves. Therefore, the user can hear the sound waves generated by the receiver by placing the receiver close to the position of the human ear. [0004] Us...
