Problems solved by technology

[0004] Although opening the air hole ensures the smooth sound output of the speaker, it will cause the sound emitted by the diaphragm and the sound coming out of the air hole to interfere with each other, resulting in a short circuit of the sound, which will make the sound of the speaker smaller and the sound quality worse. , so that the sound effect of the speaker of the terminal equipment is not good

Abstract

The embodiment of the invention discloses a terminal device. The terminal device comprises a housing, a vibration module and a driving module; the vibration module and the driving module abut againstan inner side of the housing; and when the vibration module is powered on, a magnetic field generated by the varying current in the vibration module interacts with the magnetic field of the driving module, so that the vibration module vibrates to emit sound. In the embodiment of the invention, by using the entire housing of the terminal device as the sound cavity of a loudspeaker, the sound effectof the loudspeaker of the terminal device can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a terminal device. Background technique [0002] At present, the functions of terminal devices are becoming more and more diversified. A small mobile phone can almost be used as a microcomputer, but many users still have a soft spot for a terminal device with a very prominent function, such as a music terminal device. How to optimize the sound quality of speakers is an important issue for music terminal equipment. [0003] Generally speaking, a speaker generally includes a speaker casing, a coil, a permanent magnet, and a diaphragm. When the coil is energized, a magnetic field that changes with the audio current is generated in the coil, and this magnetic field interacts with the magnetic field of the permanent magnet to make the voice coil along the The axial vibration drives the diaphragm to vibrate, so the diaphragm vibrates in the air to produce sound. At presen...
