Problems solved by technology

[0003] However, the internal electronic components of the existing power amplifier equipment are compactly arranged and generate a lot of heat. When the conventional airflow cooling method is used for heat dissipation, the heat dissipation effect is relatively poor. During heat dissipation, a large amount of dust enters the interior of the device, which is not conducive to the long-term use of power amplifier equipment

Abstract

The invention discloses a power amplifier device with dust-proof and heat-dissipating functions, which belongs to the field of power amplifier devices, and includes a bottom cover, an upper cover, a dust-proof net, a temperature controller, a dust removal box and a heat dissipation fan. The inner wall of the upper cover is provided with a dust-proof net, the inside of the bottom cover is provided with a storage box, the inside of the storage box is provided with a power amplifier body, and the bottom of the storage box is provided with a shock absorbing mechanism, which is fixed on the bottom cover, and the area between the bottom cover and the storage box A cooling fan is set in the middle of the cooling fan, cooling holes are set at the left and right ends of the cooling fan, a dust removal box is set inside the cooling hole, and a card cover is set at the lower end of the dust removal box. The invention has reasonable structural design and simple operation. By suspending the power amplifier body inside the bottom cover, the heat dissipation efficiency of the whole device is improved under the heat dissipation effect of the heat dissipation fan or the semiconductor refrigeration sheet; through the setting of the dustproof net and the dust removal box , Effectively prevent dust from entering the interior of the equipment and improve the service life of the device.

Description

technical field [0001] The invention discloses a power amplifier device, in particular to a power amplifier device with dust-proof and heat-dissipating functions. Background technique [0002] The power amplifier is the largest family of all kinds of audio equipment. Its main function is to amplify the weaker signal input by the audio equipment, and then generate a large enough current to drive the speaker to reproduce the sound. Due to the consideration of power, impedance, distortion, dynamics, and different use ranges and control adjustment functions, different power amplifiers are also different in internal signal processing, circuit design and production technology. The function of the power amplifier is to amplify the weak signal from the audio source or the pre-amplifier to push the speaker to play. A set of good audio system power amplifiers is indispensable and widely used in various audio equipment. [0003] However, the internal electronic components of the exis...
