Description

The removable storage media playing apparatus

Technical field

The utility model relates to a kind of removable storage media playing apparatus, relates in particular to a kind of and key-ring ornaments or is used as the combined a kind of removable storage media playing apparatus of gate inhibition's control structure.

Background technology

Key-ring is to be general articles for daily use, it is of a great variety, major part is animal, cartoon figure or a landscape beautiful lovely, that vivaciously set people laughing, and topmost function is with the key polyphone, makes the user do knowledge easily, use, and key-ring of new generation is more considered the problem of light illumination, be difficult to look under the situation that light is failed to understand as keyhole, therefore LED lamp on the key-ring ornaments arranged promptly, as long as push the button on it, this LED lamp lights, and makes things convenient for the user to seek keyhole.

Moreover, because the progress of science and technology, the digital device kind that is convenient for carrying now is numerous, for example mobile phone, personal digital assistant, digital camera, mobile computer, multi-functional removable storage media playing apparatus ..., though it is convenient, but still feeling numerous and diverse as carry totally, lose because of not hurrying easily, is to be its topmost defective.

The utility model is because said structure awaits improving, and so that a kind of removable storage media playing apparatus of tool integration function can be provided, consumption is popular to be used to provide, and desires to grind the utility model motivation of wound for the utility model.

The utility model content

Fundamental purpose of the present utility model provides a kind of removable storage media playing apparatus, and this device comprises the function that can listen the reward music and have key-ring.

Secondary objective of the present utility model provides a kind of removable storage media playing apparatus, this device can strengthen the ROM (Read Only Memory) of this removable storage media playing apparatus, and with important information such as maintenance telephone, operation notice, promptly use data burned, with standby at any time.

Another purpose of the present utility model provides a kind of removable storage media playing apparatus of the gate inhibition's of being used as control.

In order to achieve the above object, a kind of removable storage media playing apparatus of the present utility model, be provided with removable storage medium, its outside is provided with power switch, USB joint, several control knobs, earphone jack, microphone, and this removable storage medium inside is provided with central processing unit, numeral and analog converter, digital signal processor and transmission interface, it is characterized in that the outside of these removable storage medium is provided with a joint portion, this joint portion combines with a key ring.

The another feature of a kind of removable storage media playing apparatus of the present utility model is to have RFID less radio-frequency customer identification system in these removable storage medium.

By above-mentioned technical characterictic, compared with the prior art the utility model has following practical advantage:

1, effectively integrates key-ring and removable storage media playing apparatus, only need carry a kind of article, can reach simultaneously and unblank and the effect of listoning music.

2, these removable storage medium can be built-in RFID less radio-frequency customer identification system, can be used as the usefulness of the customer identification of gate inhibition's control, need not carry various gate inhibition's card, can the person of going everywhere without any hindrance here.

Specific embodiment of the utility model can cooperate the following drawings, is further described in detail.
