Abstract
The utility model discloses a sound system connected through Bluetooth, comprising a host and five sound boxes. The host is internally provided with a Bluetooth receiving module and the five sound boxes are used to match with the host. The host is also internally provided with an APTx Bluetooth audio decoder which can decode an audio signal into six sound channel signals of left, right, left rear, right rear and low pitch. The host is connected with the five sound boxes through a Bluetooth module to respectively transmit the decoded six sound channel signals to the five sound boxes for being displayed. The sound system adopts Bluetooth connection while wire rod connection is not required and can realize an object of a split-surround sound effect.
Description
Technical field
The utility model relates to the sound technique field, especially relates to a kind of sound system that connects by bluetooth.
Background technology
Progress along with digital technology, people's entertainment life also tends to digitlization gradually, for example the audio-visual technology of high-definition digital makes people enjoy more real entertainment life, wherein multichannel enlarger and loudspeaker are indispensable outfits, and wherein 5.1 sound channel sound systems are most basic multi-channel audio systems.5.1 the sound channel sound system is generally play on cinema, cinema and other places when audio-visual and is used, 5.1 the sound channel sound system is left horn and right horn and the supper bass loudspeaker that voice signal outputed to the left horn of preposition main sound channel and right horn, center channel loudspeaker, surround channel, make it produce 3 D space sound effect, make us just like the sense of reality on the spot in person.Though use 5.1 sound channel sound systems can be audio-visual during broadcast sound have more the sense of reality, in the prior art, each loudspeaker need have certain location interval in the 5.1 sound channel sound systems, its wiring is difficulty comparatively; Though the existing 5.1 sound channel stereo sets of supporting that bluetooth connects on the market, this equipment must with could realize 5.1 audios by wire rod connection loudspeaker again after main system of audio is connected; Or adopt 5.1 sound channels all to focus on the main frame, can not reach wireless or really split around purpose.
The utility model content
In order to overcome the problem that prior art exists, the 5.1 sound channel sound systems that the utility model provides a kind of universal blue tooth to connect, this system adopts bluetooth to connect and need not connect by wire rod, can realize audio around the purpose that splits.
The utility model is achieved by the following technical programs: a kind of sound system that connects by bluetooth, comprise the main frame of embedded with bluetooth receiver module and five audio amplifiers that are used with main frame respectively, this main frame also is built-in with APTx Bluetooth audio frequency decoder, audio signal decoding can be become left and right, in, left back, right back and six sound channel signals of bass, main frame is connected with five audio amplifiers by bluetooth module, decoded six sound channels signal is passed to five audio amplifiers respectively realize playing.
As the further improvement of the technical program, described main frame and five audio amplifiers be built-in rechargeable battery all.
As the further improvement of the technical program, described main frame internal USB charging module, the USB charging module is connected with USB interface and rechargeable battery, and rechargeable battery is the external equipment charging by USB interface.
Step as the technical program is improved built-in NFC module on the described main frame.
The utility model has following advantage with respect to prior art: use the bluetooth receiver module to realize the acoustic signal transmission in the utility model, need not connect by wire rod, solve the problem of the wiring difficulty that 5.1 sound channel sound systems exist in the prior art, and the equal built-in rechargeable battery of main frame and each sound equipment, make its putting position convenient.Built-in NFC chip and NFC antenna on the main frame make this sound system have the NFC function, and wireless connections are easier, intelligent.Internal USB charging module on this system host can charge for other portable mobile apparatus.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Be described in detail below in conjunction with the utility model of embodiment.
Embodiment
Understanding for the ease of those skilled in the art is further described in detail the utility model below in conjunction with structural representation:
As shown in Figure 1, the utility model discloses a kind of sound system that connects by bluetooth, comprise the main frame of embedded with bluetooth receiver module and five audio amplifiers that are used with main frame respectively, this main frame also is built-in with APTx Bluetooth audio frequency decoder, audio signal decoding can be become left and right, in, left back, right back and six sound channel signals of bass, main frame is connected with five audio amplifiers by bluetooth module, decoded six sound channels signal is passed to five audio amplifiers respectively realize playing.In system, use the bluetooth receiver module to realize the acoustic signal transmission, need not connect by wire rod, solve the problem of the wiring difficulty that 5.1 sound channel sound systems exist in the prior art.Described main frame and five audio amplifiers be built-in rechargeable battery all, and its main frame and each loudspeaker all be can work independently, and putting position is more convenient.Described main frame internal USB charging module, the USB charging module is connected with USB interface and rechargeable battery, and rechargeable battery is the external equipment charging by USB interface, can charge for other portable mobile apparatus.Built-in NFC module on the described main frame comprises NFC chip and NFC antenna, can charge for other portable mobile apparatus.
The not concrete construction module of introducing all can adopt mature structure module of the prior art in the utility model, does not give unnecessary details at this.
The above embodiment has only expressed execution mode of the present utility model; it describes comparatively concrete and detailed; but can not therefore be interpreted as the restriction to the utility model claim; as long as employing is equal to the technical scheme that the form of replacement or equivalent transformation obtains, all should drop within the protection range of the present utility model.
