Abstract

The invention proposes a seal verification method, a seal detection device and a seal quality measurement system. The seal detection device is used to determine the sealing quality of the microphone sound cavity of the mobile device. The seal detection device transmits a broadband audio signal from the sound source speaker through a hollow longitudinal portion into the sound cavity, and determines a sound impedance at one end of the hollow longitudinal portion. A microphone measuring part is located in the hollow longitudinal part for providing an output signal to a measuring instrument for determining a transfer function between the microphone measuring parts. The above-mentioned sealing quality of the above-mentioned sound cavity can be determined using the above-mentioned conversion function.

Description

technical field [0001] The present invention relates to audio quality testing and measurement of mobile devices, and more particularly relates to sealing quality measurement of seals between microphones and sound ports of mobile devices. Background technique [0002] Often a mobile device, such as a mobile phone, will include a microphone for receiving audio signals from a user of the mobile device. Generally, a microphone is adhered to a printed circuit board of a mobile device and is used to receive an audio signal through an acoustic cavity formed between the printed circuit board and a housing. And exposed to the external environment through the microphone port of the housing. [0003] During a call, in order to avoid the echo effect caused by the reflection of the audio signal inside the casing, a seal is provided between the casing and the printed circuit board to prevent the audio signal from entering the microphone and existing inside the mobile device. The seal sh...
