Sound box and terminal

Abstract

The invention discloses a sound box and a terminal, and relates to the technical field of acoustics. The sound box comprises a box body, a heat absorbing plate, a loudspeaker and a plurality of heat dissipation holes, heat absorbing plate is fixedly arranged in the box body, and at least one end of the heat absorbing plate extends out from the box body; the heat absorbing plate divides the box body into a first chamber and a second chamber; the plurality of heat dissipation holes are formed in the heat absorbing plate to communicate the first chamber with the second chamber; and the loudspeaker is installed in the first chamber, and the loudspeaker can drive the air circulation of the first chamber and the second chamber. The sound box disclosed by the invention can improve the heat dissipation effect and prolong the service life while ensuring the sound effect.

Description

technical field [0001] The present disclosure relates to the field of audio technology, and in particular, to a sound box and a terminal. Background technique [0002] Speakers are an indispensable part of audio-visual terminal equipment such as televisions and stereos. Using speakers, electrical signals can be converted into acoustic signals that can be listened to by the human ear. Existing sound boxes generally include a box body and a loudspeaker, and the loudspeaker is installed in the box body. Among them, paper cone speakers are widely used, and paper cone speakers generally include magnets, frames, paper cones, and voice coils. [0003] However, during the working process of the speaker, part of the electric energy will be converted into heat energy, and the heat will accumulate in the cabinet and it is difficult to dissipate in time; when the temperature is too high, problems such as burning out the voice coil and glue opening may occur, which will shorten the serv...

AI Technical Summary

Problems solved by technology

[0003] However, during the working process of the speaker, part of the electric energy will be converted into heat energy, and the heat will accumulate in the cabinet and it is difficult to dissipate in time; when the temperature is too high, problems such as burning out the voice coil and glue opening may occur, which will shorten the service life of the speaker. reduce

Especially for terminals such as TVs with ultra-thin and ultra-narrow designs, because of the small size and volume of the built-in speakers, the bass effect is poor and the sound pressure level is reduced. Generally, it is necessary to increase the power of the speakers To improve the bass effect and sound pressure level, but this will generate more heat, make it more difficult to dissipate heat, and further reduce the service life of the speaker, which is not conducive to user use
