Problems solved by technology

The current method is to use acrylic or 3D printing to manufacture different volumes of the rear acoustic cavity based on empirical data. If an acoustic problem is encountered during the test, the rear acoustic cavity can only be manually rebuilt until the problem is solved, resulting in time-consuming and labor-intensive in the entire design process. Efficiency Low, which in turn affects the design cycle of the rear cavity

Abstract

The application discloses an acoustic cavity testing system, method, device and readable storage medium, and relates to the technical field of acoustic testing. The specific implementation scheme is: obtain a test instruction; send an audio excitation signal to the speaker according to the test instruction, and receive an audio response signal from the speaker collected by the audio collection device; analyze the audio response signal , generating a control signal; sending the control signal to the driving device, so that the driving device changes the volume of the variable-volume rear acoustic cavity according to the control signal. The embodiment of the present application solves the time-consuming, labor-intensive and low-efficiency technical problems in the design process of the rear acoustic cavity, improves the design efficiency, and shortens the design period.

Description

technical field [0001] This application relates to computer technology, in particular to the technical field of acoustic testing. Background technique [0002] The sound cavity of the speaker can adjust the output frequency response curve of the speaker to a certain extent, and the high and low sound effects of the sound can be changed through the adjustment of the sound cavity parameters, and the volume of the rear sound cavity mainly affects the bass effect. [0003] When designing the rear acoustic cavity, it is necessary to test the output audio signal of the speaker in the case of different volumes of the rear acoustic cavity, so as to obtain a rear acoustic cavity with a suitable volume. The current method is to use acrylic or 3D printing to manufacture different volumes of the rear acoustic cavity based on empirical data. If an acoustic problem is encountered during the test, the rear acoustic cavity can only be manually rebuilt until the problem is solved, resulting ...
