Abstract
The utility model discloses bluetooth multichannel sound equipment, which comprises at least one audio supply source, a plurality of sound boxes which are arranged separately from the audio supply sources and are respectively provided with a built-in bluetooth terminal, and a bluetooth adapter, wherein the bluetooth adapter is connected with the audio supply sources, the bluetooth adapter is in audio line connection or bluetooth connection with the audio supply sources, and the bluetooth adapter is respectively paired and connected with bluetooth audio supply sources in the audio supply source and the bluetooth terminals of each sound box through a plurality of established independent bluetooth connecting channels. By adopting the structure, the sound boxes do not need to be connected with the signal sources by using audio lines, the bad consequence brought by the audio lines can be avoided, the materials of audio lines are saved, the played sound can be more perfect and pleasing, the bluetooth multichannel sound equipment is very suitable for the playing of a 5.1 channel or more channels, and has broad market prospect.
Description
Technical field
The utility model relates to a kind of stereo set, particularly relates to a kind of split type stereo set.
Background technology
Current stereo set is bothering aspect wiring, installation very much, connection is careless slightly, will produce a lot of adverse consequencess, cloth concealed wire in the time of finishing, also very difficult aspect maintenance, open-wire line layout, wire rod can be aging in very short time, and these factors all can be brought very large harmful effect to stereo set.
Utility model content
The purpose of this utility model is to avoid weak point of the prior art and a kind of bluetooth multi-channel audio equipment is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bluetooth multi-channel audio equipment, described stereo set comprises at least one audio frequency source of supply, and with a plurality of audio amplifiers that are all built-in with Bluetooth terminal of the separated setting of described audio frequency source of supply, described stereo set is also provided with Bluetooth adapter, described Bluetooth adapter is connected with each audio frequency source of supply, described Bluetooth adapter is that tone frequency channel wire is connected or bluetooth connects with the syndeton of audio frequency source of supply, described Bluetooth adapter is connected with each Bluetooth audio frequency source of supply in audio frequency source of supply and the Bluetooth terminal pairing of each audio amplifier respectively by a plurality of independently bluetooth interface channels of setting up.
Preferably, in each described audio amplifier, be equipped with power amplifier;
Preferably, described power amplifier external AC power supply or built-in rechargeable battery power supply.
Preferably, described each pairing that independently bluetooth interface channel is identified described in setting up by automatic cipher connects.
The beneficial effects of the utility model: owing to having adopted above structure, between audio amplifier and signal source without utilizing tone frequency channel wire to connect, can not affect because of the problem of tone frequency channel wire acoustical quality, both solved the adverse consequences that tone frequency channel wire brings, also saved the material of tone frequency channel wire, pass through Bluetooth wireless transmission, there is no the impact of wire quality factor, the transmission of audio signal source 100% puts in place, the sound playing back will be more perfect, more interesting to listen to, be applicable to very much 5,1 or the more broadcasting of multichannel, there are wide market prospects.
Accompanying drawing explanation
Fig. 1 is the Bluetooth adapter connection diagram of embodiment stereo set
Embodiment
It is below the embodiment of a preferred embodiment of the present utility model, the Bluetooth adapter connection diagram of the sound equipment of the present embodiment as shown in Figure 1, the stereo set of the present embodiment is the combined acoustics of 5.1 sound channels, be respectively equipped with preposition left, center, right, rearmounted left and right is the separate type audio amplifier of totally five embedded with bluetooth terminals, this stereo set is also provided with Bluetooth adapter, can be connected (the audio frequency source of supply in figure is respectively DVD player and CD player) with two audio frequency source of supply tone frequency channel wires simultaneously; And same Bluetooth audio frequency source of supply connect (the Bluetooth audio frequency source of supply connecting in figure is bluetooth cellular phone) by bluetooth interface channel 0 bluetooth of setting up, described Bluetooth adapter is also connected with the Bluetooth terminal pairing of above-mentioned 5 audio amplifiers respectively by setting up other 5 bluetooth interface channels (bluetooth interface channel 1 to 5); Each pairing that independently bluetooth interface channel is identified described in setting up by automatic cipher connects above; In another each audio amplifier, be equipped with power amplifier; The power amplifier external AC power supply of preposition left, center, right audio amplifier, rearmounted left and right audio amplifier is powered by built-in rechargeable battery.
The course of work of the present embodiment is: Bluetooth adapter is selected an audio signal, i.e. the audio signal of the Bluetooth signal of bluetooth cellular phone (0 transmission of bluetooth interface channel) or the tone frequency channel wire transmission by DVD player or CD player; Bluetooth adapter receives after audio signal, produces 5 audio signals after being processed, and these 5 audio signals is distributed to 5 bluetooth interface channels of foundation, is transferred to the Bluetooth terminal of 5 audio amplifiers; Each bluetooth interface channel works alone above, does not interfere with each other; The power amplifier that each Bluetooth terminal is passed to each audio amplifier by the audio signal receiving is partly processed and power amplifier, and puts outward by the loudspeaker of audio amplifier.
