Abstract

The invention discloses an audio system based on a Bluetooth transmission technology, and belongs to a wireless transmission technology. The audio system mainly solves the problem that the transmission distance is short according to an existing Bluetooth transmission technology. The audio system based on the Bluetooth transmission technology is characterized by comprises a Bluetooth receiver, a 2.4G emitter connected with the output end of the Bluetooth receiver, and playing equipment used for receiving and playing audio signals. The playing equipment comprises a 2.4G receiver matched with the 2.4G emitter, a control circuit connected with the output end of the 2.4G receiver, and a horn connected with the output end of the control circuit. According to the audio system, the wireless transmission distance is increased greatly through combination of the Bluetooth technology and the 2.4G wireless transmission technology, and the practical value is improved greatly.

Description

A kind of audio system based on Bluetooth transmission technology
 
Technical field
The present invention relates to a kind of audio playing apparatus, specifically, relate to a kind of audio system based on Bluetooth transmission technology.
Background technology
Along with the raising of quality of life, music has been dissolved among daily life completely.Existing music equipment is a lot, mobile phone, MP3, IPAD etc. have music playback function, but, no matter be that equipment, all can not carry out wireless audio frequency transmission function, even if there is equipment can carry out wireless transmission, its transmission range is also very limited, and this is limited by the transmission range of wireless network.
Summary of the invention
The object of the present invention is to provide a kind of audio system based on Bluetooth transmission technology, solve the short problem of existing audio wireless transmission range.
To achieve these goals, the technical solution used in the present invention is as follows:
An audio system based on Bluetooth transmission technology, is characterized in that, comprises Bluetooth Receiver, the 2.4G reflector being connected with the output of this Bluetooth Receiver, and for receiving the also playback equipment of playing audio signal.
Described playback equipment comprises the 2.4G receiver that you match with described 2.4G reflector, the control circuit being connected with the output of this 2.4G receiver, and the loudspeaker that are connected with the output of this control circuit.
Described control circuit comprises CPU, and is connected amplifier and filter with this CPU successively; The output of described 2.4G receiver is electrically connected to the input of described amplifier, and described loudspeaker are connected with described CPU.
Compared with prior art, the present invention has following beneficial effect:
(1) the present invention utilizes Bluetooth technology and 2.4G wireless technology to combine, thereby the distance of wireless transmission is increased greatly, has effectively solved the simple short problem of Bluetooth transmission distance, and the practical value of audio-frequence player device is improved greatly.
(2) principle of the invention is simple, realization is convenient, and cost is low, and application is wide.
Accompanying drawing explanation
Fig. 1 is system block diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figure 1, the audio system based on Bluetooth transmission technology, mainly comprises existing audio-frequence player device,, bluetooth module, 2.4G reflector and 2.4G receiver.Wherein, outside bluetooth module and 2.4G emitter position audio-frequence player device, when audio signal radios to bluetooth module, bluetooth module is transferred to 2.4G reflector again by signal, then by the 2.4G receiver that is arranged on audio-frequence player device inside, receives signal.
When 2.4G receiver receives after audio signal, first through amplifier and filter, carry out signal processing, then by CPU, control loudspeaker and play this music.
Under technical support of the present invention, utilize bluetooth and 2.4G wireless technology to combine, can realize 90 meters of wireless transmission audio-frequency functions, the distance of wireless transmission is increased greatly, practicality has obtained good raising.
Above-described embodiment is only the preferred embodiments of the present invention, and not limiting the scope of the invention, adopts design principle of the present invention in every case, and carries out non-creativeness work on this basis and the variation made, within all should belonging to protection scope of the present invention.
