Abstract
The utility model discloses a can strengthen wireless microphone receiving arrangement of signal, lay district and audio frequency processing module including casing, microphone placement area, signal reception board, be provided with microphone placement area and the district is laid to the signal reception board on the casing, be provided with audio frequency processing module in the casing, is provided with four built -in aerials in the casing, and the built -in aerial adopts formula receiving circuit very in grades. The device simple structure, reasonable in design, through embedding audio frequency processing module and radio frequency control module, it is unstable to have solved traditional microphone receiver signal transmission, and easy producing signals covers the problem of blind spot, has satisfied modern microphone receiver to the demand of the continuous signal of large tracts of land signal transmission with timely control operation situation, through upper cover and lower cover lock and the cooperation seal groove use, the effectual wireless microphone dash receiver of having protected, waterproof and dustproof effectual, the installation and dismantle the convenience change be convenient for.
Description
Technical field
The utility model relates to a kind of Signal reception plate protective device, specifically a kind of wireless microphone receiving system strengthening signal.
Background technology
Mobile loudspeaker box is the general a kind of sound-box device of present Application comparison, existing Mobile loudspeaker box in the market, microphone receiver is generally arranged on the inside of audio amplifier, received audio signal in many employings two antenna set, Signal transmissions blind spot can be there is when the antenna of transmitter and receiver is in a special position, and transmitter or receiver easily produce signal interruption when moving to different positions, greatly have impact on the stability of wireless microphone system.Simultaneously, traditional microphones plate generation signal fault, the situations such as such as transaudient interruption or tonequality are unclear, when needing to change or keep in repair, need the housing of whole audio amplifier to take apart, not only likely damage the miscellaneous part of box house, and, audio amplifier inside easily enters dust and water, and these problems are all that user brings inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of wireless microphone receiving system strengthening signal, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of wireless microphone receiving system strengthening signal, comprise housing, microphone settlement, Signal reception plate lay district and audio processing modules, described housing is provided with microphone settlement and district laid by Signal reception plate, audio processing modules is provided with in housing, four built-in aerials are provided with in housing, built-in aerial adopts true stagewise receiving circuit, and the operating frequency of built-in aerial is 740MHZ-790MHZ.
As further program of the utility model: housing adopts transparent PC material to make, and be divided into upper cover and lower cover, upper cover and lower cover fasten and use.
As the utility model further scheme: built-in aerial is connected with radio frequency control module.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, reasonable in design, by built-in audio processing module and radio frequency control module, solve the transmission of conventional microphone receiver signal unstable, the problem of easy generation quorum sensing inhibitor blind spot, meets the demand of modern microphone receiver to the continuous signal of large area Signal transmissions and timely controlling run situation; Fastened and the use of fitted seal groove by upper cover and lower cover, effectively protect wireless microphone dash receiver, waterproof and good dustproof effect, be convenient to installation and removal, be convenient for changing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the wireless microphone receiving system that can strengthen signal.
Fig. 2 is the structural representation of the wireless microphone receiving system sound intermediate frequency processing module that can strengthen signal.
Wherein: 1-microphone settlement, 2-housing, district laid by 4-Signal reception plate.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-2, a kind of wireless microphone receiving system strengthening signal, comprise housing 2, microphone settlement 1, Signal reception plate lay district 4 and audio processing modules, described housing 2 is provided with microphone settlement 1 and district 4 laid by Signal reception plate, audio processing modules is provided with in housing 2, be provided with four built-in aerials in housing 2, built-in aerial adopts true stagewise receiving circuit, and the operating frequency of built-in aerial is 740MHZ-790MHZ.Housing 2 adopts transparent PC material to make, and be divided into upper cover and lower cover, upper cover and lower cover fasten and use.Built-in aerial is connected with radio frequency control module.
Operation principle of the present utility model is: digital information is imported into audio processing modules by reception antenna by external audio information, the audio-frequency information of audio processing modules to input exports output module to after digital-to-analogue conversion, and output module exports the audio-frequency information of input the sound-box devices such as to extraneous sound console; Be provided with radio frequency control module, radio frequency control module and transmitter are responded to and are locked transmission frequency, reduce the interference of other receivers, continuous signal in ensureing 80 meters, and the frequent shift position of microphone and do not affect Received signal strength.The casing of audio amplifier is provided with the groove of the location corresponding with the shape of reception of wireless signals plate, this device is arranged in groove, and with casing horizontal parallel, installed by the mode of clinching, corresponding position is provided with the seal groove of mutual corresponding matching sealing, be convenient to handling, there is better waterproof and dust-proof effect.This apparatus structure is simple, reasonable in design, by built-in audio processing module and radio frequency control module, solve the transmission of conventional microphone receiver signal unstable, the problem of easy generation quorum sensing inhibitor blind spot, meets the demand of modern microphone receiver to the continuous signal of large area Signal transmissions and timely controlling run situation; Fastened and the use of fitted seal groove by upper cover and lower cover, effectively protect wireless microphone dash receiver, waterproof and good dustproof effect, be convenient to installation and removal, be convenient for changing.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
