[0032] Refer to the attached Figure 1-7 , a sound system in an embodiment of the present utility model.

[0033] The audio system includes a first audio device 2, a second audio device 3, and an audio cable for connecting to an external device 00 and receiving audio. The first audio device 2 includes a first control module 22, a first speaker 21 electrically connected to the first control module 22, and a first wireless module 24. The second audio device 3 includes a second control module 33, a second speaker 34 electrically connected to the second control module 33, and a second wireless module 31. The first control module 22 and the second control module 33 are both electrically connected to the audio cable, and the first wireless module 24 is wirelessly connected to the second wireless module 31. The first control module 22 receives an audio signal transmitted from an external device via the audio cable, decodes, divides, and amplifies the audio signal, and then selects a channel of audio to be played through the first speaker 21; the first control module 22 sends a wireless signal through the first wireless module 24.

[0034] The first speaker 2 of the present invention utilizes a first control module 22 to decode, frequency-divide, and amplify audio received via an audio cable from an external device, and then plays it through the first speaker 21. The second speaker 3 utilizes a second control module 33 to decode, frequency-divide, and amplify audio received via an audio cable from an external device, and then plays it through the second speaker 34. This allows the first and second speakers 2 and 3 to be directly connected to the audio of a television, computer, or the like via audio cables. Furthermore, by configuring a first wireless module 24 on the first speaker 2 and a second wireless module 31 on the second speaker 3, which is wirelessly connected to the first wireless module 24, communication is achieved between the first and second speakers 2 and 3, allowing them to play left and right channel audio, respectively, to achieve a stereo effect. This eliminates the need for an external audio decoder, amplifier, distributor, or DSP digital processor, making it convenient for users.

[0035] In one embodiment, an audio cable includes a first audio terminal 11, a second audio terminal 13, a third audio terminal 14, and two connecting wires 12. One end of each connecting wire 12 is electrically connected to the first audio terminal 11, and the other ends of each connecting wire 12 are electrically connected to the second audio terminal 13 and the third audio terminal 14, respectively. A first speaker 2 includes a first connecting terminal 23 for electrically connecting to the second audio terminal 13, which is electrically connected to a first control module 22. A second speaker 3 includes a second connecting terminal 32 for electrically connecting to the third audio terminal 14, which is electrically connected to a second control module 33. The first audio terminal 11 is used to connect to an external device such as a television or a calculator to receive an audio signal. The audio signal is then transmitted to the first control module 22 and the second control module 33, respectively, via the two connecting wires 12, the second audio terminal 13, and the first connecting terminal 23 and the second connecting terminal 32 of the third audio terminal 14, thereby transmitting the audio signal from the same external device to the first speaker 2 and the second speaker 3, respectively.

[0036] In one embodiment, the first audio terminal 11, the second audio terminal 13, and the third audio terminal 14 are all audio coaxial cable connectors, and the first connecting terminal 23 and the second connecting terminal 32 are both audio coaxial cable interfaces adapted for use with the audio coaxial cable connectors. This allows for detachable audio cables from the first speaker 2 and / or the second speaker 3, facilitating transport and portability of the system.

The first and second power interfaces can each be connected to an external power source via a power cord, or they can be connected to the same power source using two separate power cords, reducing the number of external power sources and facilitating user convenience.

The audio cable is electrically connected to the first decoder 221, the first analog frequency divider module 224 is electrically connected to the first speaker 21, and the first wireless module 24 is electrically connected to the first electronic frequency divider 222. The first decoder 221 is configured to decode the audio signal input via the audio cable and transmit it to the first electronic frequency divider 222. The first electronic frequency divider 222 is configured to electronically divide the decoded audio signal into audio signals of various frequency bands and transmit them to the first power amplifier 223 for amplification. The first analog frequency divider module 224 is configured to perform analog frequency division on the audio signal amplified by the first power amplifier 223 and then play it through the first speaker 21.

[0039] In the prior art, general audio frequency division only uses one audio method, that is, either electronic frequency division or analog frequency division. Among them, the use of electronic frequency division for audio frequency division can achieve precise frequency division, making the audio played later more flat, which leads to poor audio softness and signal smoothness. The use of analog frequency division for audio frequency division can improve the audio softness and signal smoothness after frequency division, and the sound played is softer and smoother, but the frequency division accuracy is not enough for electronic frequency division. To this end, in this embodiment, the first speaker 2 is configured with a first electronic frequency divider 222 and a first analog frequency division module 224 to achieve precise frequency division while making the audio played by the first speaker 21 relatively soft, so as to better preserve the original sound effect, so as to solve the problem that the audio obtained by the existing speakers using electronic frequency division or analog frequency division cannot simultaneously meet the requirements of precise frequency division and better audio softness.

[0040] In one embodiment, the second control module 33 includes a second decoder 331, a second electronic frequency divider 332 electrically connected to the second decoder 331, a second power amplifier 333 electrically connected to the second electronic frequency divider 332, and a second analog frequency divider module 334 electrically connected to the second power amplifier 333. The second analog frequency divider module 334 is electrically connected to the second speaker 34, and the second wireless module 31 is electrically connected to the second electronic frequency divider 332. The second decoder 331 is configured to decode the audio signal input via the audio line and transmit it to the second electronic frequency divider 332. The second electronic frequency divider 332 is configured to electronically divide the decoded audio signal into audio signals of various frequency bands and transmit them to the second power amplifier 333 for amplification. The second analog frequency divider module 334 is configured to analog divide the audio signal amplified by the second power amplifier 333 and play it through the second speaker 34. In this embodiment, the second speaker 3 is configured with a second electronic frequency divider 332 and a second analog frequency divider module 334 to achieve precise frequency division while making the audio played by the second speaker 34 relatively soft, so as to better preserve the original sound effect, thereby solving the problem that the audio obtained by the existing speakers using electronic frequency division or analog frequency division cannot simultaneously meet the requirements of precise frequency division and better audio softness.

[0041] Specifically, the first decoder 221 and the second decoder 331 can both use stereo chips, and can use chips such as AC6966B and AC6956. The first electronic frequency divider 222 and the second electronic frequency divider 332 can use chips such as JL7018 and JL7012. The first wireless module 24 and the second wireless module 31 are both antennas. The chip models of the first decoder 221, the second decoder 331, and the first electronic frequency divider 222 and the second electronic frequency divider 332 are not limited herein.

[0042] In one embodiment, the first speaker 2 further includes a first inverter 25, through which the audio line is electrically connected to the first decoder 221. The first inverter 25 is configured to amplify the audio signal input via the audio line and transmit the amplified audio signal to the first decoder 221. Since audio signals attenuate during transmission via the audio line, the first inverter 25 amplifies the audio signal input from the audio input port by inverting it twice, thereby restoring the audio signal input from the external device.

[0043] Specifically, after the first power interface is connected to the power supply, the power module converts the input power into an adaptive voltage to respectively power the first inverter 25, the first decoder 221, the first electronic frequency divider 222, and the first power amplifier 223.

[0044] In one embodiment, the second speaker 3 further includes a second inverter 35, through which the audio line is electrically connected to the second decoder 331. The second inverter 35 is used to amplify the audio signal input via the audio line and transmit the amplified audio signal to the second decoder 331. Since audio signals attenuate during transmission via the audio line, the second inverter 35 amplifies the audio signal input from the audio input port by inverting it twice, thereby restoring the audio signal input from the external device.

[0045] Specifically, after the first power interface is connected to the power supply, the power module converts the input power into an adaptive voltage to respectively power the first inverter 25, the first decoder 221, the first electronic frequency divider 222, and the first power amplifier 223.

[0046] Specifically, the first inverter 25 and the second inverter 35 can both be chips of types such as 74HC04D and 74LS04.

[0047] In one embodiment, the number of first speakers 21 is four, namely, two first tweeters and two first woofers. The number of first analog crossover modules 224 is four, wherein two first analog crossover modules 224 are each electrically connected to a first tweeter, and the remaining first analog crossover modules 224 are each electrically connected to a first woofer. The decoded audio signal is divided into a left-channel treble audio, a left-channel bass audio, a right-channel treble audio, and a right-channel bass audio through the first decoder 221 and the first electronic frequency divider 222. The four divided audio frequency bands are amplified by the first power amplifier 223 and then analog-divided by a first analog frequency division module 224. Finally, the four divided audio frequency bands are played through the first speaker 21, that is, one first speaker 21 plays the left-channel treble audio, one first speaker 21 plays the left-channel bass audio, one first speaker 21 plays the right-channel treble audio, and another first speaker 21 plays the right-channel treble audio. Thus, a first speaker 2 can play a stereo sound effect, so that a stereo effect can be achieved even when it is not used in conjunction with the second speaker 3.

[0048] In one embodiment, the number of second speakers 34 is four, namely, two second tweeters and two second woofers. The number of second analog crossover modules 334 is four; two second analog crossover modules 334 are each electrically connected to a second tweeter, and the remaining second analog crossover modules 334 are each electrically connected to a second woofer. The decoded audio signal is divided into a left-channel treble audio, a left-channel bass audio, a right-channel treble audio, and a right-channel bass audio through the second decoder 331 and the second electronic divider 332, and the four divided audio frequency bands are amplified by the second power amplifier 333 and then analog-divided by a second analog divider module 334. Finally, the four audio frequency bands are played through the second speakers 34, that is, one second speaker 34 plays the left-channel treble audio, one second speaker 34 plays the left-channel bass audio, one second speaker 34 plays the right-channel treble audio, and another second speaker 34 plays the right-channel treble audio. Thus, a second speaker 3 can play a stereo sound effect, so that a stereo effect can be achieved when it is not used in conjunction with the first speaker 2.

[0049] The first analog frequency divider module 224 and the second analog frequency divider module 334 can be low-pass filters or high-pass filters, and users can configure them accordingly based on the treble or bass played by the corresponding speakers. For example, if the first speaker 21 is a tweeter and the user plays treble, the first analog frequency divider module 224 connected to the first speaker 21 will be a high-pass filter to allow high frequencies to pass, allowing the treble audio to be played through the first speaker 21.

[0050] In the above embodiment, the first speaker 2 is provided with a first function key electrically connected to the first control module 22, and the second speaker 3 is provided with a second function key electrically connected to the second control module 33. Specifically, when a user operates the first function key, only the first control module 22 can pair the first wireless module 24 with the second wireless module 31 of the second speaker 3, thereby achieving wireless communication between the first speaker 2 and the second speaker 3.
