The invention relates to the technical field of an automatic device, and especially relates to an audio device frequency response testing device and method. The audio device frequency response testing device comprises a shielding box for providing a sealed environment for a to-be-tested audio device, and a workbench assembly which is arranged in the shielding box and is used for placing the audio device; a temperature control device for heating the audio device, and a testing data feedback device for receiving temperature signals and audio signals are arranged in the shielding box, wherein the temperature signals and audio signals are fed back by the heated audio device; the testing device also comprises a control cabinet; and the control cabinet are in communication connection with the temperature control device and the testing data feedback device and judges whether the audio device is qualified or not according to the relationships of the audio signals and the temperature signals. According to the device and the method, according to testing data formed by the relationships of the audio signals and the temperature signals, the change curve of the frequency responses of the audio device in different temperature environments is obtained; whether the tested audio device meets the requirement or not is judged automatically; and further whether the audio device is the qualified product or not is judged.
Description
technical field [0001] The invention relates to the technical field of automation equipment, in particular to an audio device frequency response testing device and method. Background technique [0002] Electronic products are getting thinner and thinner, and the density of internal components and chips is getting higher and higher. Poor heat dissipation or high heat generated during charging will lead to poor function of audio devices, such as MIC (microphone), It belongs to a small flexible circuit board. However, the existing frequency response (function) testing methods for audio devices can only detect the function of the audio device at normal temperature, but cannot detect when the electronic device heats up during charging, when the internal circuit board has poor heat dissipation and high temperature, or the external environment is high temperature. The impact of the situation on the audio device call. Therefore, it is a current development direction to design a fr...
