The loudspeaker boxes currently available on the market combine a 2.1 system and a 2.2 system, wherein the 2.1 system comprises a pair of tweeters 4 and 1 single-terminal woofer 3, and the 2.2 system comprises a pair of tweeters 4 and 2 single-terminal woofers 3. For the 2.1 system, only 1 single-terminal woofer 3 is used, so before inputting the low-frequency sound source signal to the single-terminal woofer 3, the low-frequency sound source signals of the left and right channels need to be encoded, and the encoded low-frequency sound source signal needs to be output to the single-terminal woofer 3, but the low-frequency sound source signals of the left and right channels are subjected to algorithm fusion processing during encoding, so that part of original low-frequency sound source signals are lost, and the sound effect of the sound box is reduced. For the 2.2 system, since 2 single-terminal woofers 3 need to be provided, the power consumption of the cabinet is increased. In addition, the frequency division points of the 2.1 system and the 2.2 system are high, so that the low-frequency display is not rich enough.
In order to solve the above technical problem, in the present application, woofer 3 is two-terminal woofer 31, and tweeter 4 has 2N. The processing module 2 outputs the left channel high frequency sound source signal to the N tweeters 4, and outputs the right channel high frequency sound source signal to the other N tweeters 4. The processing module 2 further outputs the left channel low frequency sound source signal to the left channel input end of the two-terminal woofer 31, and outputs the right channel low frequency sound source signal to the right channel input end of the two-terminal woofer 31. It can be seen that although the present application seemingly shows that one woofer 3 is combined with 2N tweeters 4 to form a 2.1 system, since the woofer 3 is a two-terminal woofer 31, it can simultaneously input a left channel low frequency sound source signal and a right channel low frequency sound source signal, and thus, it can be regarded as a 2.2 system in nature. Specifically, the two-terminal woofer 31 may include a diaphragm and a driving unit, the driving unit is configured to drive the diaphragm to vibrate, wherein the driving unit includes a voice coil and a magnetic circuit unit corresponding to the voice coil, and the driving unit is provided with two terminals, that is, a left channel input end and a right channel input end of the two-terminal woofer 31.
It is thus clear that in this application, because bi-terminal woofer 31 includes left channel input and right channel input, specifically can refer to side in figure 5, can input left channel low frequency sound source signal and right channel low frequency sound source signal simultaneously, consequently, need not to encode the left and right channel low frequency sound source signal of inputing to bi-terminal woofer 31 to the integrality of the former left and right channel low frequency sound source signal has been kept, the audio has been guaranteed. In addition, since only one woofer 3 is used, and the number of sound channels is not changed, power consumption is reduced and sound effects are ensured. In addition, the double terminals can reduce the low-frequency resonance frequency of the woofer 3, so that the frequency dividing points of the woofer and the tweeter can be lower when the woofer and the tweeter are matched with each other, the low-frequency playback of the sound box is facilitated, and the low-frequency sound effect is more fully displayed.
As a preferred embodiment, the processing module 2 includes a processor, a low-frequency sound effect processing chip and a high-frequency sound effect processing chip;

and the high-frequency sound effect processing chip is respectively connected with the processor and the high pitch loudspeaker 4 and is used for carrying out power amplification on the original sound source signal, filtering the low-frequency sound source signal and outputting the high-frequency sound source signal to the high pitch loudspeaker 4.
Considering that only one sound effect processing chip is usually used in the prior art speaker box, in order to avoid the delay problem of the woofer 3 and the tweeter 4 caused by the difference of the lengths of the transmission lines, the distance of the speakers cannot be separated too far.
In order to solve the technical problem, in the application, the sound effect processing chip comprises a low-frequency sound effect processing chip and a high-frequency sound effect processing chip, specifically, the low-frequency sound effect processing chip performs power amplification processing and filters high-frequency sound source signals after receiving original sound source signals, and outputs the low-frequency sound source signals to the woofer 3 so as to control the woofer 3 to replay the low-frequency sound source signals. The high-frequency sound effect processing chip is used for carrying out power amplification on the original sound source signal and filtering the low-frequency sound source signal after receiving the original sound source signal, and outputting the high-frequency sound source signal to the high-pitch loudspeaker 4 so as to control the high-frequency sound source signal to be replayed by the high-pitch loudspeaker 4.
It is thus clear that in this application, woofer 3 and tweeter 4 are controlled respectively through different audio processing chips, do not have the signal that an audio processing chip control bass loudspeaker 3 and tweeter 4 lead to and transmit the time delay problem that causes in the transmission line, have further guaranteed the audio of audio amplifier.
