Abstract

The invention relates to a speaker device by predicting and compensating for changes in sound pressure within a housing caused by at least one acoustic energy converter, and a method of driving acoustic energy converters. The speaker device includes a housing having an internal space, a first acoustic energy converter, a second acoustic energy converter, and a controller. The first and second acoustic energy converters are disposed in the housing and share the same internal space, such as a strip-shaped sound. For the speaker device, the controller uses an algorithm and a mathematical model (for example, a conversion function) on the audio signal received from the outside, so that the sounds respectively output by the first and second acoustic energy converters sharing the same internal space may be compensated, and the effect is equivalent to the first and second acoustic energy converters being separately disposed in the respective housings.

Description

technical field [0001] The present invention relates to a loudspeaker device, and more particularly to a loudspeaker system for actively canceling interaction between at least two loudspeakers sharing the same housing. Background technique [0002] In a loudspeaker system, multiple loudspeakers (also known as drivers or acoustic transducers) can be mounted on the same enclosure box, and these speakers will share the interior space in the enclosure box. When sharing the same interior space, displacement of one speaker diaphragm can affect the other speaker diaphragm due to sound pressure changes within the enclosure box. This effect is most obvious at low frequencies and seriously affects the speaker effect, and the speaker will have a relatively large diaphragm excursion at this time. [0003] For example, the speaker system may include a first speaker and a second speaker that share the interior space of the housing. When the first speaker is activated, the displacement o...
