Embodiment 1

[0087] see figure 1 , figure 1 It is a schematic flowchart of a method for automatically compensating time delay of a speaker device disclosed in an embodiment of the present invention. like figure 1 As shown, the automatic compensation delay method of the speaker device may include the following steps:

[0088] 101. The debugging device acquires the full-frequency data of the full-range speaker and the ultra-low frequency data of the subwoofer.

[0089] In the embodiment of the present invention, the full-frequency speaker can cover the range of sound frequency from 20Hz to 20KHz, and the ultra-low frequency speaker can cover the range of sound frequency from 20Hz to 100Hz. Professional subwoofers are needed to supplement and optimize the playback effect of the speaker system.

[0090] In the embodiment of the present invention, the full-frequency data may be the frequency response curve of the full-frequency speaker, and the ultra-low frequency data may be the frequency ...

Embodiment 2

[0120] see figure 2 , figure 2 It is a schematic flowchart of another method for automatically compensating time delay of a speaker device disclosed in an embodiment of the present invention. like figure 2 As shown, the automatic compensation delay method of the speaker device may include the following steps:

[0121] 201. The debugging device controls the measurement microphone to receive the full-range sound signal of the full-range speaker and the ultra-low-frequency sound signal of the ultra-low-frequency speaker.

[0122] In the embodiment of the present invention, the measurement microphone is different from the ordinary microphone. The measurement microphone needs to accurately judge and measure the frequency response, phase, signal-to-noise ratio, and spectrum analysis of the speaker. Therefore, the measurement microphone needs to have extremely high sensitivity. , all-round sound pickup range, balanced and precise frequency response curve and high sound pressure...

Embodiment 3

[0166] see Figure 4 , Figure 4 It is a structural schematic diagram of an automatic compensation delay system for a speaker device disclosed in an embodiment of the present invention. Among them, such as Figure 4 As shown, the system may include a debugging device 400, a full-range speaker 500 and a subwoofer 600, wherein the debugging device 400 includes:

[0167] The first acquiring unit 401 is configured to acquire the full-frequency data of the full-range speaker 500 and the ultra-low frequency data of the subwoofer 600 .

[0168] The first generating unit 402 is configured to generate a set of full-frequency amplitudes corresponding to different full-frequency delay values ​​by adding different full-frequency delay values ​​to the full-frequency data obtained by the first acquisition unit 401 multiple times value peak data.

[0169] In the embodiment of the present invention, the first generating unit 402 can add the same delay value to the full-frequency data mult...

Abstract

The invention discloses an automatic delay compensation method and system for a sound box device. The method comprises the steps that a debugging device acquires full frequency data of a full frequency sound box and ultralow frequency data of an ultralow frequency sound box; the debugging device generates a group of full frequency amplitude peak data corresponding to different delay values of fullfrequency by adding the different delay values of the full frequency to the full frequency data repeatedly; the debugging device generates a group of ultralow frequency amplitude peak data corresponding to different delay values of ultralow frequency by adding the different delay values of the ultralow frequency to the ultralow frequency data repeatedly; the debugging device acquires the maximumamplitude peak data in the full frequency amplitude peak data and the ultralow frequency amplitude peak data; and the debugging device sets the delay value corresponding to the maximum amplitude peakdata to the sound box corresponding to the maximum amplitude peak data. Through application of the embodiment of the invention, the delay compensation can be automatically and accurately carried out on the sound box device, and the efficiency of a debugging process is improved.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to an automatic compensation delay method and system for sound box equipment. Background technique [0002] In order to pursue the ultimate audio-visual experience, more and more people choose to bring professional speaker equipment into their homes. This kind of professional speaker equipment needs to be debugged by professional debuggers before use. To improve the listening experience, it is a very important debugging step to perform delay compensation on speaker equipment. [0003] At present, the method of delay compensation for speaker equipment is usually as follows: the debugger performs multiple delay compensation tests on the speaker equipment based on past debugging experience, and obtains the delay value used in the delay compensation test with the best auditory effect, and debugs The personnel perform delay compensation to the speaker equipment according to the dela...
