Description
Technical field
The utility model relates to electronic technology field, particularly a kind of wireless microphone.
Background technology
At present, known wireless microphone all is made up of a wireless transmission end equipment and a wireless receiving end equipment.Phase mutual interference when using in contiguous place simultaneously for fear of a plurality of wireless microphones must be used different wireless frequencies with the wireless microphone receiving equipment by every pair of wireless microphone sending ending equipment.The wireless frequency of a pair of wireless microphone sending ending equipment and wireless microphone receiving device is set, must be through setting manually guaranteeing that they use same wireless frequency, thus can accomplish communication.When the wireless transmission end equipment that need mate when wireless receiving end equipment often changes, the user has been caused very big inconvenience.
The utility model content
The utility model provides a kind of wireless microphone, can easily accomplish the automatic negotiation and the setting of the wireless frequency of wireless receiving end equipment and wireless transmission end equipment, to carry out communication.
To achieve these goals, the utility model provides following technical scheme:
A kind of wireless microphone comprises transmitting terminal and receiving terminal, and said transmitting terminal is provided with a wireless transmit chip and a MCU controller; Said receiving terminal is provided with wireless receiving chip and the 2nd MCU controller; Wherein, said receiving terminal also is provided with infrared emission head, and said transmitting terminal is provided with infrared receiving terminal; Said infrared receiving terminal signal connects a said MCU controller, and said infrared emission head signal connects said the 2nd MCU controller.
Through implementing above technical scheme; Has following technique effect: the wireless microphone that the utility model provides; In the time of need changing the wireless frequency that communication uses for the wireless transmission end equipment of wireless microphone and wireless receiving end equipment, need be through setting manually, and can carry out automatic setting through the infrared communication mode; And in a single day the frequency of accomplishing wireless microphone transmitting terminal and wireless microphone receiving terminal is consulted automatically, and the user just can carry out the use of wireless microphone.Carry out the wireless frequency of wireless transmission end equipment and wireless receiving end equipment and consult automatically, the time is very short, operate also very simple, without any need for the knowledge of wireless telecommunications or infrared communication.And add the infrared communication interface that this wireless frequency is consulted automatically for a pair of wireless microphone sending ending equipment and wireless microphone receiving device, and the electronic devices and components cost of required interpolation is very cheap, and the technology of infrared communication is the ten minutes mature and reliable also.
Description of drawings
The structure principle chart of the wireless microphone that Fig. 1 provides for the utility model embodiment.
Embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of wireless microphone, and is as shown in Figure 1, comprises transmitting terminal and receiving terminal; Said transmitting terminal is provided with wireless transmit chip and a MCU (microprocessing unit) controller; Said wireless transmit chip signal connects a said MCU controller, and said receiving terminal is provided with wireless receiving chip and the 2nd MCU controller, and said wireless receiving chip signal connects said the 2nd MCU controller; Said receiving terminal also is provided with infrared emission head; Said transmitting terminal is provided with infrared receiving terminal, and said infrared receiving terminal signal connects a said MCU controller, and said infrared emission head signal connects said the 2nd MCU controller.Transmitting terminal has audio input interface in addition; Adopt wireless communication technique to send audio signal and control signal, receiving terminal has a wireless receiving chip, is used for received audio signal and control signal; And have and audio frequency is outputed to audio-frequency power amplifier, the interface of sound multiplying arrangements such as earphone.
Because the communication distance of infrared emission head can make things convenient for and it is definite to be designed by the wireless microphone designer exactly, especially infrared ray is to belong to invisible ray, and it can not penetrate opaque barrier.Even the receiving terminal of two wireless microphones that are close to very much in the space also can be isolated through simple small and exquisite opaque barrier like this, can not cause the phase mutual interference of infrared communication.And through infrared emission head, the receiving terminal of a wireless microphone can make things convenient for exactly the transmitting terminal to the wireless microphone in the infrared signal range of receiving that gets into it to carry out infrared communication, carries out the setting of wireless frequency automatically.Like this; The user of a wireless microphone; When the receiving terminal of the transmitting terminal of the wireless microphone that he wears in hope himself and the wireless microphone of an appointment carries out wireless connections; The transmitting terminal of the wireless microphone that only need oneself be worn is put into the infrared signal transmitting boundary of the receiving terminal of specific radio microphone, and the wireless frequency that lets the transmitting terminal of his wireless microphone of being worn of receiving terminal automatic setting of wireless microphone use just can carry out the use of wireless microphone then.
The receiving terminal of the wireless microphone that this embodiment provides sends to transmitting terminal through the wireless frequency that infrared emission head uses transmitting audio signal and control signal between transmitting terminal and the receiving terminal, realizes the automatic negotiation of wireless frequency.Time is very short, operates also very simple.
More than a kind of wireless microphone that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
