Description
Technical field
The utility model belongs to wireless microphone technical field, and in particular to a kind of Wireless amplification based on automatic frequency-hopping
Device.
Background technique
Wireless microphone is that one kind by microphone converts sound into audio electrical signal, using the processing of internal circuit
Afterwards, by the space public address set of the radio wave transmission comprising audio electrical signal to surrounding.Wireless microphone is wide at home at present
The general all kinds of performing actives held applied to the places such as the place KTV, stage Karaoke, stadium and school, theater or music
Meeting, as the communication technology is more and more flourishing, radio resource seems more crowded, string frequency, disconnected frequency, radio signal interference, stabilization
The factors such as property difference, make wireless microphone the needs of needing to innovate in the prior art to meet and meet current user.But it is existing
Some UHF are more complicated to frequency mode, and after operation goes wrong, receiver is difficult to reconnect up, can not be in predeterminated frequency
Automatic cycle search is carried out in range, transfer efficiency is lower.
Utility model content
The purpose of this utility model is to provide a kind of wireless microphones based on automatic frequency-hopping, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions: a kind of Wireless amplification based on automatic frequency-hopping
Device, including emission system and reception system, emission system is made of main control chip, UHF transmitting module and antenna, on main control chip
It is connected with indicator light, key, display screen, UHF transmitting module and main control chip are connected with each other, and antenna is connected to UHF transmitting mould
On block, reception system is made of main control chip, wireless microphone receiving module, reverberation adjustment module and audio output module, main
Indicator light, key, display screen and extraneous input equipment are connected on control chip.
Preferably, the reverberation adjustment module includes wire microphone adjustment module and wireless microphone adjustment module.
Preferably, the audio output module includes circuit output, earphone output and power amplifier output three parts.
Preferably, the extraneous input equipment includes the interfaces such as bluetooth, USB flash disk, TF card, AUX IN or storage equipment.
Preferably, the emission system and reception system include battery and Charge Management equipment.
The technical effect and advantage of the utility model: the wireless microphone can effectively solve the problem that encounter interference manual operation or
When the artificial maloperation transmitter of person, the frequency variation of transmitter, receiving end can automatic frequency-hopping, automatic to connect, receiving host energy
Enough automatic frequency-hoppings, and the frequency variation of automatic connection tracking transmitter.
Detailed description of the invention
Fig. 1 is the emission system flow diagram of the utility model；
Fig. 2 is the emission system structural schematic diagram of the utility model；
Fig. 3 is the reception system flow schematic diagram of the utility model；
Fig. 4 is the reception system structure diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of wireless microphone based on automatic frequency-hopping as shown in Figs 1-4, including transmitting system
System and receive system, emission system is made of main control chip, UHF transmitting module and antenna, be connected on main control chip indicator light,
Key, display screen, UHF transmitting module and main control chip are connected with each other, and antenna is connected on UHF transmitting module, receive system
It is made of main control chip, wireless microphone receiving module, reverberation adjustment module and audio output module, is connected on main control chip
Indicator light, key, display screen and extraneous input equipment.
Specifically, the reverberation adjustment module includes wire microphone adjustment module and wireless microphone adjustment module.
Specifically, the audio output module includes circuit output, earphone output and power amplifier output three parts.
Specifically, external world's input equipment includes the interfaces such as bluetooth, USB flash disk, TF card, AUX IN or storage equipment.
Specifically, the emission system and reception system include battery and Charge Management equipment.
Emission system part: external sound chooses whether to jump out and move back after the processing of UHF transmitting module by operation frequency hopping key
Then frequency mode sends audio signal according to current frequency and new address, finally enter public frequency transmitting to frequency signal.It receives
Components of system as directed: according to the frequency and address that judge whether there is before selecting frequency signal to shut down according to last time or new pair is received
Simultaneously wireless receiving module is written in frequency signal, after receiving audio signal, if wireless signal has disconnected, in setpoint frequency range
Inside one by one then with the point of ID wireless receiving module is written again in the frequency searched out by frequency search.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
