Abstract

The invention discloses a method and a system for realizing sound effect sound field processing based on a Bluetooth speaker. The method comprises the steps of acquiring a speed value of a speed sensor in a mobile terminal based on a Bluetooth interface in the Bluetooth speaker; acquiring a center of gravity value of a gravity sensor in the mobile terminal based on the Bluetooth interface in the Bluetooth speaker; performing weighing calculation on acquired speed value and center of gravity value to obtain a weighted value; extracting a sound effect sound filed parameter corresponding to a preset weighted value based on the weighted value; and playing the extracted sound effect sound field parameter based on a Bluetooth speaker system. According to the method, due to waving of the mobile terminal, output of the overall parameter is guaranteed, the sound effect playing melody of the whole speaker is guaranteed, and so on, so that a self-entertainment state is achieved. In the overall implementation process, uniformization is performed on the speed value and the center of gravity value, so that the difference proportion of the weighted value is low, and the overall parameter output sound effect is smooth and steady.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a method and system for realizing sound effect sound field processing based on Bluetooth audio. Background technique [0002] The full name of the "DSP" system in the audio system is "Digital Sound Field Processing Technology" (Digital Sound Field Processing). It is a new type of sound field processing system developed and produced by Yamaha Corporation of Japan in the 1980s, which is specially used to produce effects similar to live performances. Yamaha's research on the sound field is mainly aimed at various sound field elements at the performance site. They found that in addition to the size and shape of the space at the performance site, various reflections of the sound play a decisive role. Generally, there are the following: kind. [0003] (1) Direct sound and reflected sound: The sound wave from the sound source directly to the listener's ear is called direct sound. Due ...
