Abstract
The utility model discloses a microphone wireless transmission adapter, wireless transmission adapter comprises casing, switch, battery, transmission circuit board, cannon plug and transmitting antenna. The utility model discloses a wireless transmission adapter can cooperate with the wired microphone of any moving-coil type of taking your socket of card, during the use, pegs graft wireless transmission adapter in the your socket of card of wired microphone, makes wired microphone do not make any change just can make wireless microphone use. It has the advantages of convenient and flexible use, and in addition, because the circuit adopts a monolithic low-voltage frequency modulation transmitting integrated circuit block IC, it has the advantages of simple structure, small volume, high working reliability, good signal quality, low cost, etc.
Description
The utility model relates to a kind of microphone.
At present, microphone of the prior art mainly contains wireless microphone and cable microphone, and the shortcoming of existing cable microphone is: because microphone has microphone cord, and microphone cord can not be oversize, if oversize then easily cause winding, impede and problems such as signal is disturbed, thereby bring inconvenience to the user; And the shortcoming of wireless microphone is that the wireless transmission part is loaded in the microphone handle together with battery, such wireless launcher can only be exclusively used in a special wireless microphone, this has had cable microphone for some and has want that existing wireless microphone still is not ideal enough with its people as the wireless microphone use.
The purpose of this utility model is: provide a kind of moving-coil type cable microphone of having combo socket of making just to can be used as the microphone wireless transmitting adaptor that wireless microphone uses without any change, had cable microphone and want its needs as the wireless microphone user to satisfy.
The utility model is to constitute like this: wireless transmitting adaptor (3) is made up of housing (4), switch (5), battery (6), radiating circuit plate (7), CANNON plug (8) and transmitting antenna (9), one end of CANNON plug (8) is fixed in the housing (4), battery (6) and radiating circuit plate (7) are contained in the housing (4), switch (5) is fixed on the housing (4), antenna (9) is connected with radiating circuit plate (7), and the lid (10) of loading and unloading battery is arranged on housing (4); Monolithic low-voltage frequency modulation emission integrated circuit block IC is housed on radiating circuit plate (7), and CANNON plug (8) is input to the signal of microphone the input of IC.
The utility model compared with prior art, because wireless transmitting adaptor (3) has adopted the CANNON formula plug general with cable microphone, it can cooperate with the moving-coil type cable microphone of any band combo socket, only need during use wireless transmitting adaptor of the present utility model (3) directly is inserted on the combo socket of moving-coil type cable microphone, microphone need not done any change, just can be used as wireless microphone like this on the cable microphone and has used.Thereby this use is novel has easy to use a, advantage flexibly, in addition, because circuit of the present utility model has adopted monolithic low-voltage frequency modulation emission integrated circuit block IC, thereby has advantages such as simple in structure, that volume is little, functional reliability is high, signal quality is good, cheap.
System configuration schematic diagram when accompanying drawing 1 uses for the utility model;
Accompanying drawing 2 is a wireless transmitting adaptor structural representation of the present utility model;
Accompanying drawing 3 is circuit theory diagrams of the present utility model.
Embodiment of the present utility model: the housing (4) of wireless transmitting adaptor (3) is made into the cylinder type with lid, its switch (5), battery (6), radiating circuit plate (7), CANNON plug (8) and transmitting antenna (9) all can adopt the finished part of selling on the cloth field to assemble, one end of CANNON plug (8) is fixed in the housing (4), radiating circuit plate (7) is contained in the housing (4), switch (5) is fixed on the housing (4), one end of antenna (9) is connected with radiating circuit plate (7), the other end stretches out outside the housing (4), lid (10) is covered after packing into battery in the housing (4); The monolithic low-voltage frequency modulation emission integrated circuit block IC employing model that goes up dress at radiating circuit plate (7) is the low-voltage frequency modulation emission integrated circuit block of BA1404, the signal of microphone (1) is input to the input of IC by CANNON plug (8), resistance R 1～R4 in the circuit, capacitor C 2～C13, inductance L 1～L2, crystal oscillator J2 are the external circuits element of IC, and its method of attachment and component parameters all are connected by the preferred circuit of BA1404 integrated package and get final product.Microphone (1) and the receiver (2) that uses that match with wireless transmitting adaptor (3) during use all can adopt the finished product of selling on the market.
Claims (2)
1, a kind of microphone wireless transmitting adaptor, it is characterized in that: wireless transmitting adaptor (3) is made up of housing (4), switch (5), battery (6), radiating circuit plate (7), CANNON plug (8) and transmitting antenna (9), one end of CANNON plug (8) is fixed in the housing (4), battery (6) and radiating circuit plate (7) are contained in the housing (4), switch (5) is fixed on the housing (4), antenna (9) is connected with radiating circuit plate (7), and the lid (10) of loading and unloading battery is arranged on housing (4).
2, microphone wireless transmitting adaptor according to claim 1 is characterized in that: monolithic low-voltage frequency modulation emission integrated circuit block IC is housed on radiating circuit plate (7), and CANNON plug (8) is input to the signal of microphone the input of IC.
