Abstract

The invention relates to an implementation apparatus and method for a 3D surround sound effect. The 3D surround sound effect apparatus comprises an I / O device, an audio decoding / digital-to-analog conversion unit, a 3D sound effect analysis unit, a power amplifier, a power management unit and a selection unit; the I / O device is sequentially connected to the audio decoding / digital-to-analog conversion unit, the 3D sound effect analysis unit and the power amplifier; in addition, the I / O device is connected to the power management unit, the 3D sound effect analysis unit and the selection unit respectively. The common function of an earphone is distinguished from the 3D surround sound effect by setting a common I / O unit and a multifunctional I / O unit in the I / O device, thereby realizing a 3D surround sound effect around a listener by controlling the output 3D surround sound when the 3D surround sound function is required.

Description

technical field [0001] The invention relates to the field of acoustic and electric technologies, in particular to a device and method for realizing 3D surround sound effects. Background technique [0002] At present, in the existing implementation schemes of portable audio equipment such as earphones, the left and right direction sense and the processing of loud and small sounds are mainly enhanced by using the left and right dual-drive speaker units, that is, two or more speakers at a certain angle are placed in the space. Speakers at different angles provide signals from one or two channels, and the position or direction of the sound source is captured by the ear by means of signal phase difference (the principle of human ear biology) to enhance the listener's stereo perception of the sound source. However, the earphones currently on the market do not have the function of converting traditional 2D audio signals into 3D audio signals, so users cannot experience 3D surround ...
