Technical Field
[0001] The present invention relates to the technical field of microphone detection, and in particular to a finished product detection device for microphones. Background Art
[0002] Microphone, also known as microphone or microphone, is a transducer that converts sound signals into electrical signals. It is widely used in recording, sound amplification, communication, conference, broadcasting, television and other fields. There are many types of microphones. According to their working principles, they can be divided into dynamic microphones, condenser microphones, contact microphones, and electromagnetic microphones. In the production process of microphones, in order to ensure product quality and performance, the microphone needs to be tested by a testing machine. The testing machine is mainly composed of a mechanical arm and a probe installed on the mechanical arm. The mechanical arm drives the probe to the detection area of the microphone. The probe collects the response signal of the microphone under specific conditions, such as the electrical output when sound is input. The testing machine compares the collected signal with the preset standard to analyze whether the performance of the microphone meets the requirements; During long-term use, the probe is directly exposed to the environment and is easily attached to tiny particles such as dust. These attachments will have a negative impact on the detection accuracy of the probe and cause deviations in the detection results. Currently, most detection machines on the market lack a self-cleaning mechanism.
