In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
Fig. 1 is a schematic flow chart of a control method of an electroacoustic device performance test device according to an embodiment of the disclosure. The embodiment can be applied to the situation of performance test of different electroacoustic devices. The method of the embodiment can be executed by a control system of the electroacoustic device performance testing device, and the system can be realized in a hardware/software mode and can be configured in computer equipment. The control method of the electroacoustic device performance testing device can be realized.
In the prior art, an electroacoustic device performance test system is adopted, namely, the sound signals of the electroacoustic device are collected through a standard wheat in the electroacoustic test system, the sound signals collected by the standard wheat are converted into electric signals through a digital-to-analog conversion module and are transmitted to the electroacoustic test system to realize the performance test of the electroacoustic device, but because the standard wheat is required to be manually placed in the prior art, the collection of the sound of the electroacoustic device is realized, and when different types of electroacoustic devices are collected, the standard wheat is required to be manually moved, on one hand, the sound outlet of the electroacoustic device and the standard wheat cannot be guaranteed to be positioned on the same horizontal plane, on the other hand, the accuracy of the distance between the standard wheat and the electroacoustic device cannot be guaranteed, and the accuracy of the test result is influenced. To solve this problem, an embodiment of the disclosure provides a control method of an electroacoustic device performance testing apparatus, where the electroacoustic device performance testing apparatus includes a standard, a first stepper motor, a test stand and a transmission mechanism, the standard is fixed on the transmission mechanism, and the first stepper motor drives the transmission mechanism to move so that the transmission mechanism drives the standard to move along the test stand.
As shown in fig. 1, the method specifically includes the following steps:

After the state information of the electroacoustic device is acquired, the sampling position is determined according to the state information of the electroacoustic device. Specifically, the sampling position is the sampling distance between the standard microphone and the electroacoustic device and/or the sampling angle between the standard microphone and the electroacoustic device. In addition, if the electroacoustic device is a component in a mobile terminal or an electronic device, due to the difference in the setting positions of the electroacoustic device, the sampling angle needs to be determined according to the position information of the electroacoustic device. For example, if the electroacoustic device in the mobile terminal is a receiver and the receiver is located at the top position of the display screen of the mobile terminal, the sampling angle between the microphone and the electroacoustic device is 90 degrees. If the electroacoustic device in the mobile terminal is a receiver and the receiver is positioned at the top of the display screen of the mobile terminal, the sampling angle between the microphone and the electroacoustic device is 90 degrees.
