Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and dustproof structures, in particular to a ventilation and dustproof structure for a large power amplifier box. Background Art

[0002] A power amplifier is commonly known as a loudspeaker. Its function is to amplify the weak signal from the sound source or pre-amplifier to drive the speaker to make sound. A good audio system plays an indispensable role in the power amplifier. Existing power amplifiers are equipped with multiple functional templates. When used, the temperature inside the power amplifier will increase, affecting the normal operation of each functional module. Therefore, heat dissipation windows will be set for ventilation and heat dissipation.

[0003] The ventilation and dustproof structure of the power amplifier in the prior art generally covers the outside of the heat dissipation window with a layer of dustproof cotton for dust prevention. In order to prevent the dustproof cotton from falling, a card holder is generally used to fix it. However, the card holders are usually set independently, which is inconvenient to adjust multiple groups of card holders at the same time. The disassembly and assembly efficiency is relatively low, which affects the replacement efficiency of the dustproof cotton. For this reason, we propose a ventilation and dustproof structure for large power amplifier boxes. Utility Model Content
