The utility model has the advantages of convenient use, good environmental protection, and perfect and beautiful appearance.
Description
Technical field
The utility model is relevant for a kind of microphone, especially refer to a kind of on the outer surface of microphone, the terminal connections that exposes for the charging use is not set, and respond to the mode that produces electric current with convergence one high-frequency electromagnetic electric wave, contactless rechargeable wired, the wireless microphone that the rechargeable battery of device in microphone inside charged.
Background technology
Amusement is more and more to pay attention to recent compatriots for daily leisure, based on popularizing of computer multi-media player, had in a lot of families now, multimedia equipments such as the jukebox of tool vocal accompaniment function or accompanying video have all been purchased, the user is as long as pass through the multimedia equipment of this class, microphone in the collocation just can be enjoyed the enjoyment of performance.
Present applied microphone is generally two kinds of wire microphone, wireless microphones, and wherein, in the wireless microphone, essential filling battery supply is with this wireless microphone of powering, with the signal outwards transmission smoothly of institute's radio reception.
But this supply power mode with the filling battery, the user, because of there not being interchangeable battery, causing re-using this microphone, and interrupts the performance atmosphere of original joy when the running down of battery in the microphone often because of no reserve battery; In addition, the housing of this microphone is in order to load battery, therefore must be provided with one can be for the battery cover or the cock of opening, imperfect except the bulk shape that makes microphone, not attractive in appearance, this battery cover or cock are damaged or get loose after also may using when long, and show its shortcoming.
In view of this utility model creator is studied innovation, discloses a kind of contactless rechargeable wired, wireless microphone.
Summary of the invention
The purpose of this utility model aims to provide a kind of contactless rechargeable wired, wireless microphone, can respond to an external electromagnetism electric wave by convergence charges to the rechargeable battery of microphone inside, make microphone reach more convenient in the use, compliance with environmental protection requirements, and profile effect complete, attractive in appearance.
According to above-mentioned purpose, a kind of contactless rechargeable wired, wireless microphone of the utility model, it is characterized in that, in the body of this microphone, has a charging circuit, this charging circuit has the induction coil that can respond to an external electromagnetism electric wave and produce electric current, and this charging circuit is connected with one group of rechargeable battery.
Wherein, this microphone comprises that also one is used to produce the high frequency generation circuit of electromagnetism electric wave; This high frequency produces circuit and comprises a rectifier that the alternating current of being imported is carried out rectification, and one is used to respond to an induction coil and the transformer that produces the high frequency frequency.
Wherein, this cradle has a pedestal, on this pedestal recessed have one can be ccontaining this microphone plant cave of inserting.
The utility model beneficial effect:
According to said structure, the utility model discloses contactless rechargeable wired, wireless microphone, has following advantage on using:
1. microphone does not need the socket power line in use or changes battery, and is more convenient on using, and compliance with environmental protection requirements.
2. microphone is placed on the cradle as the user, just can charge, need not change battery, and tool environmental protection, economic benefit.
3. do not have the charging contacts that exposes, therefore do not have the charging contacts terminal,, cause the problem that to charge because of exposing oxidation, stained for a long time to the open air.
4. need not to be provided with the device of battery case or circumscripted power line on the microphone, so its outward appearance is more apparent complete, attractive in appearance.
Desirable entity of the present utility model can by the following description and appended each be graphic, and is able to distinct.
Description of drawings
Fig. 1: structural representation of the present utility model.
Fig. 2: the applied circuit diagram of the utility model.
Embodiment
See also Fig. 1 to shown in Figure 2, the utility model system is relevant for a kind of contactless rechargeable wired, wireless microphone, in the body of this microphone 10, device has a charging circuit 11, and this charging circuit 11 contains induction coil 111, and is connected with rechargeable battery 112, make this induction coil 111 after convergence is responded to an external electromagnetism electric wave, can produce an electric current, and rechargeable battery 112 is charged, with use power supply to this microphone.
The contactless rechargeable microphone that the utility model disclosed, this external electromagnetism electric wave wherein, being derived from the high frequency generation circuit 21 that is installed in the cradle 20 sends, wherein this high frequency produces circuit 21, contain a rectifier 211, after the AC rectification of being imported, through a transformer 212 inductions one induction coil 213, and generation high frequency frequency, make this induction coil 213 behind the induction coil 111 of the charging circuit 11 of convergence microphone 10, on the induction coil 111 of the charging circuit 11 of this microphone 10, produce electric current, so that the rechargeable battery 112 that is connected is charged.
The cradle 20 that the utility model disclosed, contain a pedestal 22, on this pedestal 22, recessed have a plant cave 221, insert with ccontaining this microphone 10, so that this microphone 10 stably is inserted in this cradle 20, and make induction coil 111 ends in this microphone 10, the high frequencies installed in the pedestal 22 of this cradle 20 of leveling off to produce the induction coil 213 of circuit 21, make the induction coil 111 in this microphone 10 can respond to and produce electric current smoothly, so that rechargeable battery 112 is charged.
The utility model discloses contactless rechargeable wired, wireless microphone, when using, the user is as long as directly be inserted in microphone 10 on the cradle 20, just the operation of can charging, therefore very easy on using, and have following advantage:
1. microphone does not need in use the socket power line or changes battery, and is more convenient on using.
2. work as the user microphone is placed on the cradle, just can charge, need not change battery, and the tool environmental protection, Economic benefit.
3. do not have the charging contacts that exposes, therefore do not have the charging contacts terminal, because exposing for a long time oxidation, stained to the open air, cause not having The problem of method charging.
4. need not to arrange the device of battery case or circumscripted power line on the microphone, so its outward appearance is more aobvious complete, beautiful See.
The structure that the utility model discloses, shape can be repaiied in not disobeying to give under spirit of the present utility model and the category Decorations are used, and the utility model also will not be from limit.
