Background

In modern life, which is pursuing more and more conciseness, television sets and projection screens are continually being developed in a thinner and thinner direction, which inevitably sacrifices sound quality. In the existing mature technology, the sounding system needs enough space to generate good tone quality, and the thinner the television or the projection screen is, the smaller the space reserved for the loudspeakers in the body is, and the worse the tone quality is. In addition, televisions and projection screens pursue narrow frames, even no frames. To achieve this, designers of televisions and projection screens have backed speakers behind the screen with sound outlets directed rearward or downward to achieve a narrow, free lower bezel of the television. In this way, the built-in speaker is made to sound against the background wall, or against the desktop, rather than against the viewer. The high-pitched component of the sound is directional, and if the speaker does not sound to the viewer, the sound pressure level and definition of the high-pitched sound will be greatly reduced. Such televisions have poor sound quality, and the traditional solution is to configure a set of home theatres, but the traditional solution is heavy, complex and requires pre-buried wires, which is prohibitive for many families.

Referring to fig. 1-3, an audio signal transmission schematic diagram when an audio source device is connected to a sound system in the prior art is shown. In fig. 1, the sound system includes a sound bar 2 and a bass 3, the sound source device 1 transmits an original audio signal to the sound bar 2, the sound bar 2 decodes the audio signal, and after frequency division, transmits a part of the audio signal to a local driving circuit to drive a speaker to sound, and another part of the audio signal is transmitted to the driving circuit of the bass 3 to drive the speaker to sound. In fig. 2, the sound system includes a sound bar 2, a bass 3, a surround 4, and a surround 5, where the sound source device 1 transmits an original audio signal to the sound bar 2, the sound bar 2 decodes the audio signal, and after frequency division, a part of the audio signal is transmitted to a local driving circuit to drive a speaker to sound, another part of the audio signal is output to the bass 3, and after frequency division, the bass 3 transmits a part of the audio signal to the local driving circuit to drive the speaker to sound, and another part of the audio signal is output to the surround 4 and 5. In fig. 3, the sound system includes a sound bar 2, a bass 3, a surround 4, and a surround 5, where the sound source device 1 transmits an original audio signal to the sound bar 2, the sound bar 2 decodes the audio signal, and after the frequency division, a part of the audio signal is transmitted to a local driving circuit to drive a speaker to sound, a part of the audio signal is output to the driving circuit of the bass 3 to drive the speaker to sound, a part of the audio signal is output to the driving circuit of the surround 4 to drive the speaker to sound, and a part of the audio signal is output to the driving circuit of the surround 5 to drive the speaker to sound. In the above-mentioned several common sound systems of the prior art, when the sound bar 2 is taken to other scenes for use, the remaining bass sound box and/or surround sound box cannot be used as seen from the audio signal transmission path, which is not beneficial to meeting the diversified use demands of the multiple scenes of the user and is also not beneficial to maximizing the value of the sound system.

Aiming at the problems in the prior art, the application provides a novel sound system which can meet the use requirements of multiple scenes of users and is beneficial to maximizing the value of the sound system. Referring to fig. 4, the sound system 10 includes an audio signal box 11, a first sound box 12, and a second sound box 13, where the audio signal box 11 includes a first audio signal receiving module 111, an audio signal processing module 112, and a first audio signal output module 113; the first sound box 12 comprises a second audio signal receiving module 121 and a second audio signal output module 123, and the second sound box 13 comprises a third audio signal receiving module 131; the first audio signal receiving module 111 is configured to receive an audio signal output by the audio source device 01, the audio signal processing module 112 is configured to process the audio signal received by the first audio signal receiving module 111, and the first audio output module 113 is configured to output the audio signal processed by the audio signal processing module 112; the second audio signal receiving module 121 is connected to the first audio signal output module 113, and is configured to receive an audio signal output by the first audio signal output module 113, and the third audio signal receiving module 131 is connected to the first audio signal output module 113 or the second audio signal output module 123, and is configured to receive an audio signal output by the first audio signal output module 113 or an audio signal output by the second audio signal output module 123, and when the sound system is composed of the audio signal box 11, the first sound box 12, and the second sound box 13, the third audio signal receiving module 131 may be connected to the first audio signal output module 113 to obtain an audio signal, or may be connected to the second audio signal output module 123 to obtain an audio signal, and when the sound system includes the audio signal box 11 and the second sound box 13, the third audio signal receiving module 131 is connected to the first audio signal output module 113 to obtain an audio signal.

The audio signal box 11 receives an audio signal output by the audio source device 01 through the first audio signal receiving module 111, specifically, the first audio signal receiving module 111 may be a common audio input port of a sound box such as a USB port, an HDMI port, an optical fiber port, an AUX port, or the like, that is, the audio signal box 11 is connected to the audio source device 01 in a wired manner. AUX port (auxliary) refers to an audio input port that can input audio (a general headphone jack) of electronic audio devices including mp3, and can output music in these devices through sound in a car.

Of course, in other embodiments, the audio signal box 11 may also be connected to the audio source device 01 in a wireless manner, for example, a wireless connection module dongle is plugged into the audio source device 01, and a corresponding wireless connection module dongle is plugged into the audio signal box 11, so as to realize wireless connection between the audio source device and the audio signal box 11. In general, in order to ensure smooth signal transmission, the audio signals output by the audio source device 01 are all encrypted or compressed signals, the audio signals output by the audio source device 01 are received by the first audio signal receiving module 111 of the audio signal box 11 and then transmitted to the audio signal processing module 112, and the audio signal processing module 112 decodes the audio signals and outputs the decoded audio signals through the first audio signal output module 113. It should be noted that, the first audio signal output module 113 may be a wireless transmission signal module, or may be a port connected to an audio transmission line.

In an application scenario, the audio signal box 11 is connected with the audio signal of the first sound box 12, the first sound box 12 is connected with the audio signal of the second sound box 13, at this time, after the audio signal output by the audio signal box 11 reaches the first sound box 12, the audio signal processing module 122 performs the frequency division processing, a part of the audio signal is output to the driving circuit 124 of the first sound box 12, the driving circuit drives the speaker 125 to sound according to the part of the audio signal, another part of the audio signal is output to the driving circuit of the second sound box 13 through the second audio signal output module 123 of the first sound box 12, and the driving circuit drives the speaker 135 to sound according to the part of the audio signal. In this application scenario, the audio signal box 11 may be connected to the audio signals of the first speaker 12 and the second speaker 13, and after the audio signal box 11 receives the audio signal output by the audio source device, a part of the audio signal is decoded and divided into frequency and then output to the first speaker 12, and another part of the audio signal is output to the second speaker 13.

In another application scenario, referring to fig. 4a and 4b, the first sound box 12 is taken by the user into another scenario, for example, the first sound box 12 is connected to the sound source device 02 to be used as a bluetooth sound box. Referring to fig. 4b, the remaining audio signal box 11 and the second speaker 13 form a new sound system 101, and the audio signal box 11 receives the audio signal output by the audio source device 01, decodes the audio signal, and outputs the decoded audio signal to the second speaker 13. The first sound box 12 and the second sound box 13 are one of a strip sound box, a surround sound box and a bass sound box. It should be noted that, since the bass speaker can only output middle bass, in the usage scenarios shown in fig. 4a and 4b, in order not to affect the user experience, the first speaker 12 and the second speaker 13 are speakers with full-frequency speakers, such as a bar speaker or a surround speaker.

In this embodiment, the user can split the sound system into 2 independent sub-sound systems for use, that is, the user only needs to purchase one set of sound system, so as to meet the use requirements of multiple scenes and diversify, and does not need to purchase a bluetooth sound box after purchasing the sound system, thereby maximally reflecting the value of the sound system and saving the equipment purchase cost for the user.

It should be noted that when using the audio system to play audio, the audio signal is first sent to the audio signal box 11 through the audio source device, where the audio signal is in the form of an electrical signal, and cannot be directly heard by us, and then enters the audio signal box 11, and after being decoded, the audio signal is subjected to an amplifier (or may be subjected to an amplifying process when the first speaker box 12 or the second speaker box 13 is used), where the amplifier is used to increase the voltage and the current of the audio signal to a sufficient level so as to drive the speaker unit. The speaker unit of the enclosure is the most important part of the enclosure, including the driving circuit and the speakers. The speaker has a membrane, typically made of a material such as paper, plastic or metal. When an electrical signal passes through the drive circuit, it is transferred to the diaphragm, causing it to begin vibrating. The vibrating diaphragm produces sound waves in the air, which are audible to us. The speed and amplitude of the vibration of the diaphragm determines the pitch and volume of the sound. Eventually, the generated sound waves will propagate out of the enclosure, through the air to our ears. The acoustic waves are received by our auditory system and converted into sound that we can perceive and understand.

Audio source devices generally refer to source devices that output audio signals for televisions, projectors, CD players, MP3 players, radios, and the like.

After receiving the audio signal output by the audio source device 01, the audio signal box 11 decodes the audio signal, outputs a part of the decoded audio signal to the driving circuit of the first sound box 12 to drive the speaker of the first sound box 12 to sound, outputs another part of the decoded audio signal to the second sound box 13, carries out frequency division processing after receiving the audio signal, and outputs a part of the audio signal to the driving circuit of the local machine to drive the speaker to sound, and outputs another part of the audio signal to the driving circuits of the third sound box 14 and the fourth sound box 15 to drive the speaker to sound. In another embodiment, the audio signal box 11 is connected with the first sound box 12, the second sound box 13, the third sound box 14 and the fourth sound box 15 through audio signals sequentially, after the audio signal box 11 receives the audio signal output by the audio source device 01, a part of the audio signal is output to the driving circuit of the first sound box 12 to drive the speaker of the first sound box 12 to sound, another part of the audio signal is output to the second sound box 13 to perform the frequency division processing after receiving the audio signal, a part of the audio signal is output to the driving circuit of the second sound box 13 to drive the speaker of the second sound box 13 to sound, and another part of audio signal is output to the driving circuits of the third sound box 14 and the fourth sound box 15 to drive the speakers of the third sound box 14 and the fourth sound box 15 to sound. Or the processing chip with stronger processing capability is integrated in the audio signal box 11, the audio signal box 11 can divide the audio signal into proper audio signal branches according to the number of the sound boxes in the sound system, play corresponding audio signals in the corresponding sound boxes, and send irrelevant audio signals to other sound boxes. For example, in the embodiment shown in fig. 5, the audio signal box 11 receives the audio signal output by the audio source device, and divides the audio signal into four paths of signals S1, S2, S3, and S4 after decoding, when the audio signal is transmitted to the first sound box 12, the signal S1 is used for being sent to the driving circuit to drive the speaker to sound, the signals S2, S3, and S4 are continuously transmitted to the second sound box 13, the signal S2 is used for being sent to the driving circuit to drive the speaker to sound, and the signals S3 and S4 are respectively transmitted to the third sound box 14 and the fourth sound box 15 to drive the speakers of the third sound box 14 and the fourth sound box 15 to sound.

Referring to fig. 5a and 5b, the sound system 10 can be split into a sub-sound system 101 and a sub-sound system 102 under different application scenarios, for example, the sub-sound system 101 includes an audio signal box 11, a second sound box 13, a third sound box 14 and a fourth sound box 15. The second sound box 13 can be connected with the audio signal box 11 to acquire audio signals and then transmit the audio signals to the third sound box 14 and the fourth sound box 15, so that the whole sub-sound system 101 can be ensured to be used normally.
