Description
Technical field
The utility model relates to sound technique field, especially a kind of wireless acoustics based on pick-up coil.
Background technology
Traditional audio amplifier, power amplifier are normally connected with playback equipment in the mode of tone frequency channel wire, are controlled by audio-frequence player device, and it takies larger space, also have and adopt integral structure, still there is larger, the unhandy problem of volume.And the Portable intelligent terminal of the increasingly extensive use of people is as very general in mobile phone, panel computer etc., but these Portable intelligent terminals are when displaying audio file, and acoustic efficiency is poor.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For the deficiencies in the prior art part, under the purpose of this utility model is to provide a kind of volume, easy to operate, the wireless acoustics based on pick-up coil that sound result of broadcast is good.
For achieving the above object, the technical scheme that the utility model adopts is:
Based on a wireless acoustics for pick-up coil, comprise rechargeable battery, pick-up coil, amplifying circuit and loudspeaker, described rechargeable battery connects with the power interface of pick-up coil, amplifying circuit; Described pick-up coil is linked in sequence amplifying circuit, voice optimization circuit, power amplification circuit and loudspeaker.
Preferably, also comprise a power circuit, this power circuit is provided with charging inlet; The output of described power circuit is connected with rechargeable battery; This rechargeable battery connects with a MCU, and this MCU connects with power circuit.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, namely finally to be played back by loudspeaker through a series of circuit after the audio signal of Portable intelligent terminal near it being become electronic signal by pick-up coil, not only easy to operate but also sound effect is good; By the setting of power circuit and MCU, extend the useful life of rechargeable battery.
Accompanying drawing explanation
Accompanying drawing 1 is functional-block diagram of the present utility model.
In figure, each label respectively: (10) rechargeable battery, (20) pick-up coil, (30) amplifying circuit, (40) loudspeaker, (50) voice optimization circuit, (60) power amplification circuit, (70) power circuit, (80) MCU.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Refer to Fig. 1, a kind of wireless acoustics based on pick-up coil of the utility model, comprises rechargeable battery 10, pick-up coil 20, amplifying circuit 30 and loudspeaker 40, and described rechargeable battery 10 connects with the power interface of pick-up coil 20, amplifying circuit 30, described pick-up coil 20 is linked in sequence amplifying circuit 30, voice optimization circuit 50, power amplification circuit 60 and loudspeaker 40, the structural design of above, when Portable intelligent terminal is as mobile phone, panel computer etc. near pick-up coil 20 and displaying audio file time, the audio signal received is become electronic signal and delivers to amplifying circuit 30 by pick-up coil 20, this amplifying circuit 30 prevents signal oscillating and carries out denoising Processing to signal and signal is delivered to voice optimization circuit 50, bass and the middle pitch of this voice optimization circuit 50 pairs of signals strengthen, then signal delivers to loudspeaker 40 after power amplification circuit 60, by loudspeaker 40, signal is played back, sound effect is all good.
The utility model also comprises a power circuit 70, and this power circuit is provided with charging inlet, for external civil power; The output of described power circuit 70 is connected with rechargeable battery 10; This rechargeable battery 10 connects with a MCU80, this MCU80 connects with power circuit 70, the structural design of above, charging current is exported to rechargeable battery 10 after power circuit 70 pairs of civil powers carry out rectification and voltage stabilizing, MCU80 then detects the voltage of rechargeable battery 10, when not being inconsistent with rated voltage appears in the voltage of rechargeable battery 10, MCU80 controls power circuit 70, and then control the charging current of power circuit 70 output, make it be in a constant charge state for a long time, thus extend the useful life of rechargeable battery.
In sum, the utility model is by above-mentioned structural design, solve the problem of Portable intelligent terminal displaying audio file of the prior art, not only easy to operate, and sound effect is especially good, the useful life of rechargeable battery can be extended simultaneously well, there is market value and huge market potential widely.
Certainly, the utility model also has other to be out of shape.In a word, according to the prompting of above-described embodiment and the apparent variation made, and other every changes not departing from the utility model essence, all should be included within the scope described in claim.
