Description

Technical Field

[0001] The utility model relates to the technical field of audio production and detection, in particular to a double silicon microphone test tooling. Background Technique

[0002] The silicon microphone, abbreviated as silicon mic, is a microphone manufactured using semiconductor technology and MEMS technology, and is a new type of substitute for traditional microphones. Different from traditional capacitive or dynamic microphones, the silicon microphone uses a non-contact diaphragm with a thickness of only a few micrometers, so it can capture extremely tiny sound wave signals, thereby achieving the sound capture effect of ultra-high sensitivity, wide frequency response, and low distortion. The silicon microphone has the advantages of small size, light weight, low power consumption, and high mechanical strength. Due to its use of semiconductor technology, it also has relatively strong resistance to extreme environments such as high temperature, high humidity, and high pressure, and can be applied in relatively harsh environments such as automobiles, aviation, and ships. In addition, due to the high sensitivity of the silicon microphone, when applied to scenarios such as intelligent voice assistants and smart homes, it can better trigger voice commands and recognize user voices, improving the accuracy and convenience of voice interaction.

[0003] At present, when testing the functions of a double silicon microphone, workers often hold the product with one hand, align the two sound collection ports of the product with the sound generator respectively, and press the test button with the other hand. However, this test method is not convenient for employees to operate, and the test accuracy of holding the product to align with the sound generator is greatly affected by humans, resulting in the test results not being able to ensure consistency, being prone to errors, and at the same time not being convenient for continuous testing, causing the problem of low test efficiency.

[0029] As Figure 2 and 3 shown, the bottom of the test disc 46 is fixedly connected to the top end of the rotating rod 41, and the outer surface of the rotating rod 41 is fixedly connected to the inner surface of the first ratchet 42.

[0030] As Figure 2 and 3 shown, the outer surface of the first ratchet 42 meshes with the outer surface of the first tooth block 43, and one end of the first spring 44 is fixedly connected to the inner wall of the first fixing bracket 45.
