Embodiment Construction
[0031] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0032] First, the nouns involved in this application are explained:
[0033] NULL area: refers to the zero sound pressure area in the sound field formed by the directional speaker. A directional loudspeaker can be realized by two loudspeakers close together, for example, the simplest directional loudspeaker can be realized by using a dipole type loudspeaker....

An embodiment of the present application provides an audio signal processing method and an electronic device. The method includes: if at least two users are currently detected, obtaining the first position of the right ear of the leftmost user and the first position of the left ear of the rightmost user. Two positions; according to the original left channel signal and the first position, determine the first input signal of the left positive speaker and the second input signal of the left negative speaker, so that the NULL area of the output sound field of the left speaker points to the first position; and according to the original The right channel signal and the second position determine the third input signal of the right positive speaker and the fourth input signal of the right negative speaker, so that the NULL area of the output sound field of the right speaker points to the second position; according to the first input signal, the second The input signal, the third input signal and the fourth input signal respectively drive the left positive speaker, the left negative speaker, the right positive speaker and the right negative speaker, realizing the control of the NULL direction of the sound field of the speaker, and effectively improving the user's listening effect.
Description
technical field [0001] The present application relates to the field of multimedia technologies, in particular to an audio signal processing method and electronic equipment. Background technique [0002] In the audio world, the practical use of directional speaker systems is one of the methods of bass reproduction. Currently, there are two directional speakers on the left and right sides of the TV equipment, which can be called the left speaker and the right speaker, which are used to play the left channel signal and the right channel signal of the TV respectively, so that the user can hear the sound of the TV. sound. [0003] However, in the prior art, since the direction of the directional speaker is forward, the user on the left side mainly hears the sound from the left speaker, and hears little sound from the right speaker. This causes the sound field heard by the user to be to the left, and the sound field heard by the user on the right is also to the right. The sound...
