Problems solved by technology

Although this method avoids the problem of unstable intermediate frequency response, its weight coefficient setting and threshold selection lack a strong theoretical basis, and can only be adjusted by trial and error, which is time-consuming and laborious.

Abstract

The invention discloses a method and a device for determining a position of a loudspeaker, and the loudspeaker. The method comprises the following steps of obtaining new frequency response data which is measured when the loudspeaker is at the current position, wherein the frequency response data is an amplitude frequency response which is measured when the loudspeaker plays audio data at the current position; respectively carrying out matching operation on the new frequency response data and a position model of the loudspeaker at different positions to obtain a plurality of matching results; and determining the current position of the loudspeaker according to the matching results. According to one embodiment of the invention, the position of the loudspeaker is automatically determined.

Description

technical field [0001] The present invention relates to the technical field of audio signal processing, and more particularly, to a method and device for determining the position of a loudspeaker, and a loudspeaker. Background technique [0002] When the speaker is in different positions in the room, due to the different distances from the surrounding reflective surfaces, its acoustic radiation characteristics will change, which will affect the user's listening experience. Therefore, it is necessary to perform specific equalization processing on the played audio according to the position of the speaker. Before equalizing the played audio, it is necessary to know the current position of the speaker. According to the distance from the speaker to the reflective surface and the number of reflective surfaces, the position of the speaker can be divided into three categories: "free", "edge of the wall" and "corner". For the three different positions, targeted equalization can be pe...
