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 invention discloses a vocal cavity testing system, method and device and a readable storage medium, and relates to the technical field of acoustic testing. According to the specific implementationscheme, the method comprises the steps of: obtaining a test instruction; sending an audio excitation signal to the loudspeaker according to the test instruction, and receiving an audio response signal sent by the loudspeaker and collected by the audio collection device; analyzing the audio response signal to generate a control signal; and sending the control signal to the driving equipment, so that the driving equipment changes the volume of the volume-variable rear vocal cavity according to the control signal. According to the embodiment of the invention, the technical problems of time and labor waste and low efficiency in the rear vocal cavity design process are solved, the design efficiency is improved, and the design period is shortened.

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 ...
