Abstract

The utility model relates to a Bluetooth stereophonic sound box, comprising a first horn, a first voice frequency power amplifier, a second horn, a second voice frequency power amplifier, a main Bluetooth chip, a secondary Bluetooth chip, a main Bluetooth antenna and a secondary Bluetooth antenna. The main Bluetooth chip is respectively connected with the first voice frequency power amplifier and the main Bluetooth antenna, the secondary Bluetooth chip is respectively connected with the second voice frequency amplifier and the secondary Bluetooth antenna, and the main Bluetooth antenna is connected with the secondary Bluetooth antenna through wireless signals. For the Bluetooth stereophonic sound box disclosed by the utility model, voice frequency signals are transmitted between the two horns of a left sound channel and a right sound channel through the Bluetooth so that the trouble of wiring between the two horns is omitted, and a true wireless stereophonic sound box is realized.

Description

The Bluetooth stereo audio amplifier
Technical field:
The utility model relates to the audio amplifier field, specifically is a kind of Bluetooth stereo audio amplifier.
Background technology:
Original Bluetooth stereo audio amplifier generally is placed on the bluetooth receiver module on the loudspeaker and received signal, on second loudspeaker that the L channel and the R channel of audio amplifier is connected to audio amplifier by wired mode, perhaps two loudspeaker is placed in the casing then; If realize real stereo, distance between two loudspeaker must reach certain size, just must couple together between such two loudspeaker with tone frequency channel wire, the wiring of this root tone frequency channel wire bothers very much under a variety of situations, and causes this wireless stereo speaker itself to lose wireless meaning.
The utility model content:
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, and a kind of wiring puzzlement of saving is provided, and really realizes the Bluetooth stereo audio amplifier of wireless transmission audio signal.
Technical solution of the present utility model is, a kind of Bluetooth stereo audio amplifier is provided, it comprises first loudspeaker, first audio frequency power amplifier, second loudspeaker, second audio frequency power amplifier, described first audio frequency power amplifier is connected with first loudspeaker, described second audio frequency power amplifier is connected with second loudspeaker, it also comprises main Bluetooth chip, inferior Bluetooth chip, main Bluetooth antenna, inferior Bluetooth antenna, described main Bluetooth chip is connected with first audio frequency power amplifier and main Bluetooth antenna respectively, described time Bluetooth chip is connected with second audio frequency power amplifier and time Bluetooth antenna respectively, and described main Bluetooth antenna is connected by wireless signal with time Bluetooth antenna.
After adopting said structure, the utlity model has following advantage:
The utility model is transferred to another loudspeaker with stereosonic one road signal (L channel or R channel) of main Baffle Box of Bluetooth by the Bluetooth chip, between two loudspeaker of left and right sound channels is to carry out transmitting audio signal by bluetooth, save the puzzlement of connecting up between two loudspeaker, realized wireless stereo audio amplifier truly.
Description of drawings:
Accompanying drawing is the functional-block diagram of the utility model Bluetooth stereo audio amplifier;
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of Bluetooth stereo audio amplifier, it comprises first loudspeaker, first audio frequency power amplifier, second loudspeaker, second audio frequency power amplifier, described first audio frequency power amplifier is connected with first loudspeaker, described second audio frequency power amplifier is connected with second loudspeaker, it also comprises main Bluetooth chip, inferior Bluetooth chip, main Bluetooth antenna, inferior Bluetooth antenna, described main Bluetooth chip is connected with first audio frequency power amplifier and main Bluetooth antenna respectively, described time Bluetooth chip is connected with second audio frequency power amplifier and time Bluetooth antenna respectively, and described main Bluetooth antenna is connected by wireless signal with time Bluetooth antenna.Described main Bluetooth chip and time Bluetooth chip all adopt commercially available Bluetooth chip, its model is BC57E687, master chip is used for receiving the stereophonic music signal that mobile phone or other Bluetooth adapter transmit, inferior Bluetooth chip is used for receiving the music signal that main Bluetooth chip passes a sound channel of coming, it is the audio frequency power amplifier of TPA6211 that described first audio frequency power amplifier and second audio frequency power amplifier all adopt model, be used for amplifying audio signal, drive loudspeaker, describedly live Bluetooth antenna and time Bluetooth antenna all adopts the PIFI antenna, be used for emission, receive wireless signal.
Operation principle of the present utility model is: main Bluetooth chip receives the music signal that mobile phone or adapter transmit by main Bluetooth antenna, the signal of a sound channel is passed to first loudspeaker by first audio frequency power amplifier, the signal of another one sound channel is sent to time Bluetooth chip by main Bluetooth antenna, inferior Bluetooth chip receives the signal that main Bluetooth antenna sends by inferior Bluetooth antenna, export the audio signal of another sound channel, and drive second loudspeaker by second audio frequency power amplifier.
Certainly; above-mentioned explanation is not to be limit value to essential scope of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art person has done in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection range of the present utility model.
