Problems solved by technology

[0003] The internal structure of a traditional bluetooth stereo device is shown in Figure 1, wherein the function of the microprocessor 10' is weak no matter whether it is on the speaker or on the earphone, and the sound effect processing function is relatively weak. For example, when playing music, the sound effect of the subwoofer is often There are noises, and the subwoofer cannot be perfectly presented; when the subwoofer is too loud, it will break the sound, or the overtone at the high pitch is too small, making the sound thin and difficult to enter the ear. It is necessary to increase the subwoofer processing and simulate various sound fields. The sound effects and the dynamic equalizer (Dynamic Equalizer, D-EQ) processing functions are coordinated, including dynamic equalizers, graphic equalizers and parametric equalizers for precise control

Embodiment Construction

[0018] In the following detailed description through specific embodiments, it should be easier to understand the purpose, technical content, characteristics and effects of the present invention.

[0019] The invention provides a method for increasing the sound effect processing function of a bluetooth stereo device, which can compensate for the lack of subwoofer, simulate the sound effect processing functions of various sound fields, and automatically adjust the gain and parameters in the equalizer (EQ). Due to the wide range of Bluetooth stereo devices, the method for increasing the audio processing function of the present invention will be described below by taking a Bluetooth stereo headset as an example.

[0020] Fig. 2 is a structural diagram of the internal components of the bluetooth stereo earphone of the present invention, and its difference with Fig. 1 is that the microprocessor 10 of the bluetooth stereo earphone of Fig. 2 further includes an audio effect processing ...

Abstract

A method for adding sound effect process function of a Bluetooth stereo device is provided in the present invention, adding a digital signal process technology to the Bluetooth stereo device and adding a sound effect process module for processing stereo sound source series flow, adding special sound effect series flow into the form of the sound source series flow after subband coding (Subband coding, SBC) decoding received by the Bluetooth stereo device, sound effect process function containing super bass process function, sound effect simulating various sound fields and process function of the dynamic equalizer, wherein the super bass process bases on using human ear lost basic frequency effect, and the simulating various sound fields bases on the rebound of sound in space, sound positioning process technology and sound effect simulating technology etc., leading the stereo sound effect to be perfect while process sound effect process.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a method for adding subwoofer processing functions, simulating the sound effects of various sound fields and the processing functions of dynamic equalizers to a Bluetooth stereo device. Background technique [0002] With the gradual development of science and technology, various real-time and convenient electronic devices are constantly being developed to meet the needs of people's lives to meet the needs of simplicity, convenience, and portability. Among them, wireless transmission technology has made great progress. Mobile phones, computers, keyboards, mice, and earphones can all use Bluetooth wireless transmission technology. For example, Bluetooth wireless earphones allow users to listen to music within the range no matter they are doing or walking. , without the trouble of being hindered by the transmission line. [0003] The internal structure of a tradit...
