Description
Technical field
The present invention relates to sound system, particularly relate to a kind of numeral bicycle sound system.
Background technology
Along with improving constantly of people's living standard, arrive the first-selected leisure way that countryside body-building has become people's Our Nature by bike, and everybody is while by bike, often likes listening to the music, and loosens body and mind.At present, mostly ride friend and all carry with MP3, then put on earphone and listen to the music, but there is many drawbacks in the mode of this listoning music: one is that duct blocked by earphone, add musical sound, bicyclist is difficult to hear the alarming sound from surrounding enviroment, there is certain potential safety hazard; Two is wear earphone concert for a long time to cause very major injury to the brain of people and hearing, is unfavorable for health; Three is wear trouble, and inconvenience is carried in operation.Therefore, the individual demand that a kind of sound system being applicable to bicycle meets people is badly in need of.In addition, when bicycle leaves the people visual field, for preventing theft, need to install warning device additional, thus point out owner and draw back burglar with fear.If sound system and warning device can be integrated, great facility will be brought.
Summary of the invention
The technical problem to be solved in the present invention is for the weak point existing for prior art, there is provided a kind of numeral bicycle sound system, structure is simple, safe and reliable, can meet people by bike time the individual demand of listening to the music at any time, possess anti-theft alarm function again simultaneously.
For achieving the above object, technical scheme of the present invention is: numeral bicycle sound system, comprise main frame, loudspeaker and Digiplex, described main frame comprises one for controlling the audio frequency central processing unit of whole sound system work, audio frequency central processor circuit is connected with storer, radio receiver module, audio amplification block, alarm module and wireless receiving control module, radio receiver signal and audio decoder signal export audio amplification block to and are connected with loudspeaker after audio frequency central processing unit switches, described loudspeaker comprises left speaker and right loudspeaker, it is individually fixed in the left side on bicycle handlebar, right both sides, described Digiplex is provided with the wireless transmitter module corresponding with wireless receiving control module.
The power supply supply of this system comprises outside lithium battery and built-in lithium battery, and both realize switching and being connected with audio frequency central processing unit in main frame and each module respectively by the break-make of power supply DC socket negative pole.
Described alarm module comprises the vibration transducer, audible alarm unit and the electronic switch unit that are controlled by audio frequency central processing unit.
Described storer is SD card.
Described loudspeaker is waterproof full frequency speaker.
Described main frame is placed in the front-axle beam bag of bicycle.
The left and right sound channels stated between main frame and loudspeaker is connected with two core shielding lines.
The invention has the beneficial effects as follows: structure is simple, safe and reliable, can meet the individual demand of people, effectively prevent and wear earphone and to listen to the music the potential safety hazard existed, the loudspeaker be located on handlebar facilitates oneself and the companion that goes on a tour jointly listens to the radio programme and listens to the music; Meanwhile, this system is also integrated with burglar alarm, can carry out alarm, and be attached with electronic lock function, only have and could trigger releasing by telepilot, greatly strengthen the security of bicycle, reduce loss by theft rate vehicle abnormality vibration.In addition, the outside lithium battery of setting can effectively avoid built-in lithium battery not have the electric inconvenience brought, practical.
Accompanying drawing explanation
Fig. 1 is functional-block diagram of the present invention.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
As shown in Figure 1, numeral bicycle sound system, comprises the main frame be placed in the front-axle beam bag of bicycle, is fixed on the left and right loudspeaker on the left and right handlebar of bicycle and a Digiplex.Described main frame comprises one for controlling the audio frequency central processing unit of whole sound box system work, and audio frequency central processor circuit is connected with SD card memory, radio receiver module, alarm module, audio amplification block and wireless receiving control module.Radio receiver signal and audio decoder signal export audio amplification block to and are connected with the loudspeaker on handlebar after audio frequency central processing unit switches, and as preferably, waterproof full frequency speaker selected by loudspeaker, so that rainy day use.Described audio frequency central processing unit is connected with functional switch, supply socket and audio frequency accessory power outlet, the left and right sound channels between described main frame and loudspeaker is connected with two core shielding lines, and shielding line is as the receiving antenna of FM radio receiver module and wireless control module.
Described alarm module comprises the vibration transducer, audible alarm unit and the electronic switch unit that are controlled by central processing unit.Described Digiplex is provided with the wireless transmitter module corresponding with wireless receiving control module, and controls the button of the electronic lock button of electronic switch unit, the change-over switch button controlling radio receiver module or audio decoder module work, control volume and selected song.
The power supply supply of this system comprises outside lithium battery and built-in lithium battery, and both realize switching and being connected with audio frequency central processing unit in main frame and each module respectively by the break-make of power supply DC socket negative pole.Outside lithium battery is connected to main frame outside by the supply socket of main frame.Outside lithium battery can effectively avoid built-in lithium battery not have the electric inconvenience brought.When built-in lithium battery does not have an electricity, only need connect outside lithium battery, this sound system just can work, very convenient.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
