Description
Technical field
The utility model relates to a kind of digital product charging device, relates in particular to a kind of both playbacks in addition, and the digital product that can charge is put charging device outward again.
Background technology
When the digital product of now a lot of mobile phones or MP3, MP4 etc. need charge, can charge by charger, wherein, the power input of charger connects external power supply (mains supply or vehicle power), the output terminal of charger is with after the charging port of digital product is connected, the logarithmic code product charges, and after charging finished, digital product continued to use again.By above-mentioned aspect as can be seen, adopt this kind charge mode logarithmic code product to charge, can be subjected to the restriction of region, promptly travelling outdoors or during field work, both do not had mains supply, when not having vehicle power, can't the digital product of mobile phone or MP3, MP4 etc. have been charged yet.And general charger has only charge function, and does not have outer player function and microphone function, and its function is comparatively single, and usable range is narrow.
(Granted publication number is CN2447943Y to disclose a kind of charger for mobile phone at Chinese utility model patent instructions, Granted publication day is September 12 calendar year 2001), its clip Text is as follows: a kind of charger for mobile phone, comprise shell and be arranged on wherein charging circuit, the input plug that is connected with external power supply, the output plug that is connected with battery of mobile phone, in above-mentioned shell, be provided with reserve battery in addition, and be provided with a may command reserve battery with the reserve battery cooperation and in position be connected the knob that is communicated with by certain circuit with input plug and output plug respectively, this reserve battery can be rechargeable battery, this charger both can be connected with external power, battery of mobile phone and reserve battery are charged, when no external power, can charge to mobile phone by reserve battery again, bring convenience to the user, and complete machine structure is simple, the convenient use.
Above-mentioned utility model discloses a kind of charger for mobile phone that has reserve battery, substantially solved and travelled outdoors or during field work, the problem that the digital product of mobile phone or MP3, MP4 etc. is charged, but, its function is still more single, promptly just have charge function, and do not possess playback, microphone function, its usable range still is narrow.
The utility model content
The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, provided a kind of both the solution to travel outdoors or during field work, to the problem that the digital product of mobile phone or MP3, MP4 etc. charges, the multi-functional digital product that also has playback, microphone function is put charging device outward.
In order to solve technical matters recited above, the utility model is taked following technical scheme:
A kind of digital product is put charging device outward, have a housing, be arranged on the charging circuit in the housing, the power input interface that connects external power supply, the charging output interface of linking number code product battery, the microphone that also is provided with audio output circuit, the loudspeaker that are electrically connected with audio output circuit, microphone input circuit in the described housing and is electrically connected with the microphone input circuit.
Wherein, described digital product is mobile phone, MP3 or MP4.
Also be provided with the standby rechargeable battery that is electrically connected with charging circuit in the described housing, standby rechargeable battery one end is connected with charging circuit, and the other end is electrically connected with the charging output interface.
As a kind of preferred version, described digital product is put charging device outward and is also included the earphone interface that is electrically connected with audio output circuit.
Described digital product is put charging device outward and is also included the playback mode switch that is used to select loudspeaker playback or earphone playback.If when wanting to use loudspeaker to carry out outer playback, the playback mode switch is transferred to loudspeaker playback pattern; If when using the earphone playback, the playback mode switch is transferred to earphone playback pattern.
As a kind of preferred version, described digital product is put charging device outward and is also included the microphone starting switch.Use the microphone starting switch, can be when the mobile portable phone the tinkle of bells sounds, press the microphone starting switch after, receive calls, and carry out communication by microphone and the other side.
The utility model had both solved by a standby rechargeable battery and had travelled outdoors or during field work, the problem that the digital product of mobile phone or MP3, MP4 etc. is charged, also by a microphone input circuit and an audio output circuit, the realization audio frequency is put outward and the voice dialogue function, receive calls conveniently, and be convenient for carrying, cost is also low, has more wide usage range.
