Sound box and system

Abstract

The invention discloses a sound box and a system. The sound box comprises a shell, and a processing module, a double-terminal woofer and 2N high pitch loudspeakers which are arranged in the shell, the double-terminal woofer is provided with two input ends, specifically, a left channel input end and a right channel input end, the double-terminal bass loudspeaker receives a left sound channel low-frequency sound source signal and a right sound channel low-frequency sound source signal through the left sound channel input end and the right sound channel input end respectively. Through the mode, the left and right sound channel low-frequency sound source signals input to the double-terminal woofer do not need to be coded, so that the integrity of the original left and right sound channel low-frequency sound source signals is reserved, and the sound effect is ensured; only one woofer is used, but the number of sound channels is not changed, so that the power consumption is reduced, and the sound effect is ensured; besides, the double terminals can reduce the low-frequency resonance frequency of the bass loudspeaker, so that the frequency division point of the bass loudspeaker and the high-pitch loudspeaker can be set to be lower when the bass loudspeaker is matched with the high-pitch loudspeaker, the low-frequency playback of the sound box is facilitated, and the low-frequency sound effect is displayed more sufficiently.

Description

technical field [0001] The invention relates to the technical field of sound generating equipment, in particular to a sound box and a system. Background technique [0002] Common speaker combinations currently on the market include 2.1 system and 2.2 system. Among them, the 2.1 system includes a pair of tweeters and a single-terminal woofer, and the 2.2 system includes a pair of tweeters and two single-terminal woofers. For the 2.1 system, since only one single-terminal woofer is used, before inputting the low-frequency audio source signal to the single-terminal woofer, it is necessary to encode the low-frequency audio source signals of the left and right channels, and encode the encoded low-frequency audio source The signal is output to the single-terminal woofer, but because the algorithm fusion processing is performed on the low-frequency audio source signals of the left and right channels during encoding, part of the original low-frequency audio source signal will be los...

Problems solved by technology

For the 2.1 system, since only one single-terminal woofer is used, before inputting the low-frequency audio source signal to the single-terminal woofer, it is necessary to encode the low-frequency audio source signals of the left and right channels, and encode the encoded low-frequency audio source The signal is output to the single-terminal woofer, but due to the algorithmic fusion processing of the low-frequency audio source signals of the left and right channels during encoding, part of the original low-frequency audio source signal will be lost and the sound effect of the speaker will be reduced

For the 2.2 system, due to the need to set two single-terminal woofers, the power consumption of the speaker is increased

In addition, the crossover points of the 2.1 system and 2.2 system are relatively high, resulting in insufficient low-frequency display
