Speaker detection device and method

Abstract

The embodiments of the invention relate to the technical field of speaker detection, and particularly relate to a speaker detection device and method. The speaker detection device includes at least four speaker interfaces, a detection module, and a main control module. The detection module is electrically connected with the speaker interfaces, and is used for collecting the impedance voltage of each channel. The main control module is electrically connected with the detection module, and is used for determining whether the impedance voltage of any channel is greater than a first predetermined voltage, and determining that the two speaker interfaces on the channel are qualified if the impedance voltage of the channel is greater than the first predetermined voltage. It can be seen that, for double or multiple speakers, whether there is a short circuit between two speaker interfaces is no longer manually measured through a universal meter. In the invention, whether the two speaker interfaces on a channel are qualified is determined by collecting the impedance voltage and determining whether the impedance voltage of the channel is greater than the first predetermined voltage through the main control module. Thus, double or multiple speakers can be detected quickly, and the detection efficiency of double speaker interfaces or multiple speaker interfaces can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of horn detection, in particular to a horn detection device and method thereof. Background technique [0002] The speaker factory needs to test whether there is a short circuit between the positive and negative poles of the speaker before the speaker is shipped. At present, for a single speaker, a frequency scanner can be used to test the short circuit of a single speaker. Since the frequency scanner is a single-channel output, so , The frequency scanner can only test the short circuit of a single speaker. As for whether there is a short circuit between the positive and negative poles of double speakers or multiple speakers, use a multimeter to measure manually. Put it on a stripped head of the terminal, and put the other needle on the stripped head of the other three wires in turn. If the multimeter shows that it is not conductive, it means it is qualified, and repeat this to measure ...

As for whether there is a short circuit between the positive and negative poles of double speakers or multiple speakers, use a multimeter to measure manually. Put it on a stripped head of the terminal, and put the other needle on the stripped head of the other three wires in turn. If the multimeter shows that it is not conductive, it means it is qualified, and repeat this to measure the other three wires. It needs to be tested 6 times in total. , although it is possible to test out the short circuit defects in all cases, but the number of manual tests is too many, which affects the detection efficiency
