Electronic equipment

Abstract

The application discloses electronic equipment. The electronic equipment comprises a first loudspeaker used for producing the sound not higher than the first frequency, wherein a first cavity arranged at one side of the first loudspeaker and used for outputting the sound produced by the vibration of the first loudspeaker; a second cavity arranged at other side of the first loudspeaker; a functional device set with a functional device capable of producing heat; and a hollow pipe arranged in the second cavity, wherein the air in the second cavity enters the hollow pipe and is ejected from the hollow pipe under the vibration effect of the first loudspeaker, and the air ejected from the air-out end can be used for radiatingheat ofthe functional device. By use of the electronic equipment provided by the invention, the hollow pipe is arranged in the second cavity to guide the air vibrated and driven by the loudspeaker, thereby realizing the heat radiation of the functional device; a large number of heat radiation holes are unnecessary to be arranged, and the fan is unnecessary to add, so that the electronic equipment can realize the heat radiation of the functional device in the premise of not influencing the appearance, and not increasing the noise, and the heat radiation mode of the electronic equipment is optimized.

Description

technical field [0001] The invention relates to the technical field of electroacoustic equipment, in particular to an electronic equipment. Background technique [0002] At present, electronic devices such as smart speakers and multimedia speakers have become common sound playback devices in people's daily production. With the improvement of the quality of life, people have higher and higher requirements for audio effects and beautiful appearance of speakers. [0003] The existing audio system generally uses a set of functional devices to control its automatic operation, and the set of functional devices is a printed circuit board (PCB) provided with a micro control unit (MCU). The set of working functional devices and the functional devices (such as micro control units) set on it are all heating elements, and the heat emitted by them will have a certain impact on the normal operation of the audio, especially the power amplifier on the audio. If it is tens of watts or even ...

AI Technical Summary

Problems solved by technology

The set of working functional devices and the functional devices (such as micro control units) set on it are all heating elements, and the heat emitted by them will have a certain impact on the normal operation of the audio, especially the power amplifier on the audio. If it is tens of watts or even hundreds of watts, the impact on the normal operation of the audio cannot be ignored. Therefore, it is necessary to timely and effectively dissipate the heat dissipation of the functional device set and the micro control unit. The existing heat dissipation method is generally on the shell of the smart audio Open a large number of cooling holes, or add fans in the smart speaker, but opening a large number of cooling holes will affect the appearance of the smart speaker, and adding fans will increase the noise and affect the sound playback effect of the smart speaker
