Abstract
The utility model discloses a Bluetooth sound with a line output port, which comprises a power supply, a Bluetooth module, a processor unit, an audio-frequency amplifier and a loudspeaker, wherein the line output port which can be connected with external equipment through a data line is also arranged; the line output port is connected to the sound channel output end of the processor unit; therefore, the equipment not only can be used as playing equipment for receiving Bluetooth signals but also can be used as a Bluetooth signal processor; received audio-frequency information is transmitted into sound equipment with higher quality through a data line to be played or output into other external equipment with a sound processing function through the data line to be used; therefore, the application range of the Bluetooth sound is wider.
Description
Technical field
The utility model relates to a kind of Bluetooth audio device.
Background technology
Along with popularizing of portable type electronic product, some stereo sets are provided with the wireless data interface adaptive with audio and video player, by carrying out transfer of data between the wireless communication techniques such as bluetooth and the audio and video player, the audio-frequency information of audio and video player output is play after the sound effect processor of stereo set inside is processed, convenient and swift, enriched people's life.
But, the Bluetooth audio device of prior art just uses as a playback equipment that can receive Bluetooth signal merely, when being transferred to by data wire in other more high-quality sound appliances, plays the audio-frequency information that Bluetooth audio device need to be received, the external equipment with acoustic processing function of perhaps exporting to other through data wire as: when sound amplifier, sound pick-up outfit etc. use, Bluetooth audio device is just helpless, the scope of application of greatly having limited to Bluetooth audio device.
The utility model content
For the Bluetooth audio device that overcomes prior art can only be play, the audio-frequency information that receives can not be transferred to the deficiency of other external equipments, the utility model provides a kind of Bluetooth audio device with the line output mouth.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Bluetooth audio device with the line output mouth, comprise power supply, receive the bluetooth module of Bluetooth signal, the processor unit that links to each other with described bluetooth module, and the audio frequency amplifier and the loudspeaker that connect described processor unit signal output part, also be provided with the line output mouth that can connect by data wire external equipment, described line output mouth connects the sound channel output of described processor unit.
For the scope of application that makes described line output mouth is wider, described line output mouth is audio jack.
As a kind of improvement of technique scheme, described processor unit comprises microprocessor and sound effect processor.
For described line output mouth can also be used as the line input mouth, described line output mouth connects the outside sound channel input of sound effect processor simultaneously, be provided with electronic switch between the outside sound channel input of described line output mouth and sound effect processor, described electronic switch connects the signal output part of microprocessor.
The beneficial effects of the utility model are: be provided with the line output mouth that connects processor unit sound channel output, making equipment not only can be used as a playback equipment that receives Bluetooth signal uses, can also use as the Bluetooth signal processor, the audio-frequency information that receives is transferred in other more high-quality sound appliances by data wire plays, perhaps in data wire is exported to other the external equipment with acoustic processing function, use, make the scope of application of Bluetooth audio device wider.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is operation principle block diagram of the present utility model;
Fig. 2 is the operation principle block diagram of the utility model embodiment;
To be the utility model transfer schematic diagram to audio amplifier with Bluetooth signal to Fig. 3;
To be the utility model transfer schematic diagram to sound processing apparatus with Bluetooth signal to Fig. 4.
Embodiment
Referring to figs. 1 through Fig. 4, a kind of Bluetooth audio device with the line output mouth of the present utility model, comprise power supply, receive the bluetooth module of Bluetooth signal, the processor unit that links to each other with described bluetooth module, and the audio frequency amplifier and the loudspeaker that connect described processor unit signal output part, also being provided with the line output mouth that can connect by data wire external equipment, described line output mouth connects the sound channel output of described processor unit.
In this embodiment, described power supply comprises external power source interface, power source charges manager, battery, power electronic switch and voltage changer, so that equipment both can pass through external power source, can pass through powered battery again.Power supply provides electric energy for respectively bluetooth module, processor unit, audio frequency amplifier and loudspeaker.
Described processor unit comprises microprocessor and sound effect processor.Microprocessor sends control signals to sound effect processor and bluetooth module.Bluetooth module can receive the blue teeth wireless signal that external equipment sends, the output of bluetooth module connects the signal input part of sound effect processor, the left and right sound channels output of sound effect processor connects audio frequency amplifier, plays by loudspeaker after treatment.The left and right sound channels output of sound effect processor also exports signal to line output mouth place.
In this embodiment, for the scope of application that makes described line output mouth is wider, the 3.5mm audio jack that described line output mouth is standard.
For described line output mouth can also be used as the line input mouth, described line output mouth connects the outside sound channel input of sound effect processor simultaneously, be provided with electronic switch between the outside sound channel input of described line output mouth and sound effect processor, described electronic switch connects the signal output part of microprocessor, and microprocessor sends electronic switch and controls signal to the electronic switch place.
When this product uses as Baffle Box of Bluetooth, the bluetooth module of this interiors of products receives external equipment such as the signal of the electronic equipments such as panel computer with Bluetooth function, notebook computer, mobile phone, and the loudspeaker by this product after the sound effect processor of this interiors of products is processed broadcast.
This product also can be with external equipment by the defeated voice signal that comes of data wire, is broadcasted by the loudspeaker of this product after the internal sound surround processor is processed again.
When this product uses as the Bluetooth signal processor, inner bluetooth module receives external equipment, as has a signal of the electronic equipment such as panel computer, notebook computer, mobile phone of Bluetooth function, after the sound effect processor is processed, be reduced into voice signal and export to outside other tool with the equipment of acoustic processing function by the 3.5mm audio socket of this product through data wire, sound amplifier for example, the uses such as sound pick-up outfit.
Certainly, the utility model can also have other structural distortion except above-mentioned execution mode, and these equivalent technical solutions also should be within its protection range.
