Abstract
The utility model discloses a musical bar. The music bar is characterized by comprising a shell, wherein a sound box, a USB interface circuit, a power interface circuit and an audio interface circuit are arranged in the shell, and an interface is arranged on the shell and electrically connected with the USB interface circuit, the power interface circuit and the audio interface circuit. The music bar is provided with only one interface which is also circular and is the same with an audio interface, while the interface integrates the following four functions: firstly, power charge (when a charger is inserted or the interface is connected with an audio output interface of a computer, music playing and charging can be simultaneously carried out; secondly, data transmission (the uploading and downloading of data file can be realized just by using the ordinary audio interface so that a USB data interface can be completely replaced, and charging can also carried out simultaneously); thirdly, audio output; and fourthly, audio input ( the interface is connected with peripheral equipment), namely that one interface can replace five conventional interfaces: the USB interface, the power supply interface, a battery charging interface, the audio input interface and the audio output interface.
Description
Technical field
The utility model relates to a kind of music rod, is a kind of music rod simple in structure, easy to use specifically.
Background technology
The music rod is used in above the high-grade bicycle (racing car), is on the steel pipe of fixed cover on the racing car head generally speaking, is used for listening to MP3, and the MP4 music can connect earphone, and also the lug machine is not externally play.Existing MP3 music rod routine on the market all has two interfaces, one is circular audio output interface, another is the data transmission interface of flat, also be to be exactly USB interface and power interface that we often say, since two interfaces separately, make the structure of music rod comparatively complicated and use not too convenient.Existing music rod all just possesses self music playback function, connects the independent music appreciating of earphone, perhaps pulls out the earphone playing back music.
Summary of the invention
The purpose of this utility model provides a kind of music rod simple in structure, easy to use.
The purpose of this utility model is achieved through the following technical solutions:
A kind of music rod, it is characterized in that: described music rod comprises housing, be provided with audio amplifier and audio playing circuit in the housing, file storage circuit and usb circuit, power interface circuit, audio interface input and output circuit, housing is provided with an interface, and this interface is electrically connected with usb circuit, power interface circuit, audio interface input and output circuit.
The utility model compared with prior art has the following advantages.
Music rod described in the utility model only is provided with an interface, also be circular, the audio interface of seeing at ordinary times with us is the same, but this interface synthesis following four kinds of functions: 1. power source charges (is plugged charger, perhaps just go up playing back music on one side, Yi Bian charged) with the audio output interface connection of computer; 2. transfer of data (just can realize uploading and downloading of data file with common audio interface, can replace the usb data interface fully); 3. audio frequency output; 4. audio frequency input (external playback equipment).That is to say that an interface can replace three interfaces of our routine: USB interface, power interface and audio interface.
Description of drawings
Fig. 1 is the structural representation of the utility model music rod.
Embodiment
Below in conjunction with accompanying drawing the utility model music rod is described in further detail.
As shown in Figure 1, music rod described in the utility model mainly is made up of housing 1 and the audio amplifier, usb circuit, power interface circuit, the audio interface circuit that are arranged in the housing.Housing is provided with an interface 2, and this interface is electrically connected with usb circuit, power interface circuit, audio interface input and output circuit.The music rod has music playback function, both can connect the independent music appreciating of earphone, also can pull out the earphone playing back music, can also come usefulness as independent sound equipment simultaneously, as long as external input tone frequency channel wire just can be used as a power amplifier sound equipment.
