Embodiment Construction
[0028] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:
[0029] Such as figure 1 , a method for adjusting loudspeaker loudness, comprising the steps of:
[0030] S1. The signal source sends the sound signal to the digital signal processor, and the digital signal processor sends the processed sound signal to the power amplifier, and the power amplifier amplifies the sound signal and sends it to the speaker, and the speaker makes a sound;
[0031] S2. The collection device collects the actual loudness information of the sound emitted by the speaker, and sends the collected information of the actual loudness to the digital signal processor;
[0032] S3. The digital signal processor compares the actual loudness with the preset loudness, and then adjusts the sound signal in a targeted manner according to the comparison result.

The invention relates to a horn loudness adjusting method, which belongs to the field of horns, and comprises the following steps that: S1, a signal source sends a sound signal to a digital signal processor, the digital signal processor sends the processed sound signal to a power amplifier, the power amplifier amplifies the sound signal and transmits the amplified sound signal to a horn, and the horn makes a sound; S2, the acquisition device acquires vibration information of a vibrating diaphragm 5 of the loudspeaker during sound production and sends the acquired vibration information to a digital signal processor, and the digital signal processor analyzes and processes the vibration information and calculates actual loudness corresponding to the vibration information; and S3, the digitalsignal processor compares the actual loudness with the preset loudness, and then performs targeted adjustment on the sound signal according to the comparison result. The sound production error of theloudspeaker can be eliminated.
Description
technical field [0001] The invention relates to the field of speakers, in particular to a method for adjusting the loudness of the speakers. Background technique [0002] Music is an important part of people's spiritual enjoyment. With the development of science and technology, there are more and more terminals capable of playing audio files, such as speakers, mobile phones, computers, MP3 and so on. A speaker generally refers to a device that converts an audio signal into sound. Its role is often to convert audio power into corresponding sound energy through the speaker, and radiate it into the space. However, during the production process or with the increase of use time, the speaker in the speaker will have a certain error in its structure and the preset structure, resulting in a certain error in the sound it emits, although the error can be kept within the standard However, it will still affect the user experience, so there is an urgent need in this field for a loudne...
