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...
