Problems solved by technology
At Figure 1C Among them, due to the different positions of the first sound receiving part 81, the second sound receiving part 82 and the third sound receiving part 83 of the microphone 8, the detection sound waves transmitted to the first sound receiving part 81, the second sound receiving part 82 and the third sound receiving part 83 S produces different sound wave reflection phenomena, and the reflected sound will also affect the reception of the detection sound wave S by the first sound receiving part 81, the second sound receiving part 82 and the third sound receiving part 83, thereby causing the first sound receiving part 81, the second sound receiving part The second sound receiving part 82 and the third sound receiving part 83 are in the low frequency section, for example: between 100Hz~200Hz, and the high frequency section, for example: above 2000Hz, the consistency of their frequency response curves is relatively poor, causing the microphone detection system 9 to fail. Accurately detect whether the sound receiving function of the microphone 8 is normal in the low frequency range and high frequency range

The invention provides a microphone detection device for detecting the sound collection function of the microphone, which includes a detection platform, a standard speaker module, a fixing piece and a pedestal, wherein the sleeve of the standard speaker module has a conical through hole, and the conical through hole The detection sound waves produced by standard loudspeakers can be concentrated, thereby reducing the interference caused by sound wave reflections.
Description
technical field [0001] The invention relates to a detection device, in particular to a detection device for microphone detection. Background technique [0002] With the advent of the Internet age, at any time and any place, people can use electronic devices to communicate and communicate with each other through wireless networks at any time. Therefore, the microphone used for calling or receiving instructions has also become one of the basic equipments of electronic devices, such as smart watches, notebook computers, tablets, personal digital assistants, smart phones or game consoles. [0003] A general microphone usually has multiple sound-receiving parts. Therefore, after the microphone is manufactured, the sound-receiving function of each sound-receiving part must be tested separately. In the known technology, such as Figure 1A and Figure 1B as shown in Figure 1A is a known microphone detection system; Figure 1B It is a well-known microphone detection device. At ...
