Abstract

The invention discloses a miniature loudspeaker detection system and a detection method thereof. The miniature loudspeaker detection system comprises an audio frequency transmitting unit, an audio frequency control unit, an audio frequency amplifying unit and a connecting plate unit, wherein the audio frequency transmitting unit is electrically connected with the audio frequency control unit and the audio frequency amplifying unit respectively; the audio frequency control unit adjusts the output voltage of the audio frequency transmitting unit, the audio frequency amplifying unit amplifies thevoltage value of the output voltage, the connecting plate unit is provided with a plurality of groups of connecting ports, and the plurality of groups of connecting ports are connected to a miniatureloudspeaker to be tested. According to the miniature loudspeaker detection system and the detection method thereof, the audio frequency transmitting unit outputs the voltage, the voltage is amplifiedafter passing through the audio frequency amplifying unit and finally flows into the to-be-detected miniature loudspeaker through voltage division of the connecting plate unit, and the performance condition of the to-be-detected miniature loudspeaker can be effectively detected.

Description

【Technical field】 [0001] The invention relates to a micro-speaker detection system and a detection method thereof, in particular to a micro-speaker detection system and a detection method for a rugged tablet computer. 【Background technique】 [0002] With the development of consumer electronics products in the direction of multi-function, personalization, portability and high fidelity, micro electro-acoustic components are being developed in the direction of ultra-miniaturization, digitization, integration and modularization. Miniature electro-acoustic components, like consumer electronics, have shorter and shorter life cycles and faster replacement speeds. The market demand for miniature microphones and miniature speakers is increasing. However, due to the complicated production process of micro-speakers, performance testing must be carried out before leaving the factory. The detection method at this stage is as follows: connect the micro-speaker to the audio source device,...
