The utility model content
The technical problems to be solved in the utility model is: a kind of numeral bicycle sound system is provided, and it is simple in structure, and is safe and reliable, can satisfy the individual demand that people listen to the music by bike the time at any time, possesses again anti-theft alarm function simultaneously.
To achieve these goals, the technical solution adopted in the utility model is: a kind of numeral bicycle sound system, comprise main frame, loudspeaker and Digiplex, described main frame comprises an audio frequency central processing unit that is used for controlling whole sound system work, audio frequency central processing unit circuit is connected with storer, radio receiver module, the audio frequency amplification module, alarm module and wireless receiving control module, described radio receiver signal exports the audio frequency amplification module with the audio decoder signal to and is connected with loudspeaker after the audio frequency central processing unit switches, described loudspeaker comprises left speaker and right loudspeaker, and it is individually fixed in the left side on the bicycle handlebar, right both sides; Described telepilot is provided with the wireless transmitter module corresponding with the wireless receiving control module.
As preferably, the power supply of this system is supplied with and is comprised outside lithium battery and built-in lithium battery, both respectively the break-make by power supply DC socket negative pole realize switching and be connected with audio frequency central processing unit and each module in the main frame.
As preferably, described alarm module comprises vibration transducer, audible alarm unit and the electronic switch unit by the control of audio frequency central processing unit.
As preferably, described storer is the SD card.
As preferably, described loudspeaker is the waterproof full frequency speaker.
As preferably, described main frame places in the front-axle beam bag of bicycle.
As preferably, the left and right sound channels between described main frame and the loudspeaker is connected with two core shielding lines, and wherein two heart yearns are used for audio transmission, and shielding line is as the receiving antenna of FM radio receiver module and wireless control module.
The beneficial effect that the utility model brings is: this sound system is simple in structure, safe and reliable, can satisfy people's individual demand, effectively avoid wearing the potential safety hazard that earphone is listened to the music and existed, be located at the convenient own and companion that goes on a tour of loudspeaker on the handlebar and jointly listen to the radio programme and listen to the music; Simultaneously, this system also is integrated with burglar alarm, can carry out alarm to the vehicle abnormality vibration, and be attached with electronic lock function, only has by telepilot and could trigger releasing, has greatly strengthened the security of bicycle, reduces loss by theft rate.In addition, the inconvenience that the outside lithium battery of setting can effectively avoid built-in lithium battery not have electricity to bring, practical.
Description of drawings
Fig. 1 is the functional-block diagram of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of numeral bicycle sound system comprises the main frame in the front-axle beam bag that places bicycle, is fixed in left and right loudspeaker and a Digiplex on the left and right handlebar of bicycle.Described main frame comprises an audio frequency central processing unit that is used for controlling whole sound box system work, and audio frequency central processing unit circuit is connected with SD card memory, radio receiver module, alarm module, audio frequency amplification module and wireless receiving control module.Described radio receiver signal and audio decoder signal export the audio frequency amplification module to and are connected with loudspeaker on the handlebar after the audio frequency central processing unit switches, as preferably, loudspeaker is selected the waterproof full frequency speaker, so that the rainy day use.Be connected with functional switch, supply socket and audio frequency accessory power outlet on the described audio frequency central processing unit, left and right sound channels between described main frame and the loudspeaker is connected with two core shielding lines, wherein two heart yearns are used for audio transmission, and shielding line is as the receiving antenna of FM radio receiver module and wireless control module.
Described alarm module comprises vibration transducer, audible alarm unit and the electronic switch unit by central processing unit control.Described telepilot is provided with the wireless transmitter module corresponding with the wireless receiving control module, and the button of the change-over switch button of the electronic lock button of control electronic switch unit, control radio receiver module or the work of audio decoder module, control volume and selected song.
The power supply of this system is supplied with and is comprised outside lithium battery and built-in lithium battery, both respectively the break-make by power supply DC socket negative pole realize switching and be connected with audio frequency central processing unit and each module in the main frame.Outside lithium battery is connected to the main frame outside by the supply socket of main frame.The inconvenience that outside lithium battery can effectively avoid built-in lithium battery not have electricity to bring.When built-in lithium battery does not have electricity, only need to connect upper outside lithium battery, this sound system just can be worked, and is very convenient.
