Abstract
The utility model discloses a USB interface wireless audio emitting receiver, comprising a USB interface wireless audio emitter and a USB interface wireless audio receiver. A USB interface is inserted into the host, audio signals are transmitted to an audio signal emitting module through the USB interface and then converted into digital signals through the audio signal emitting module and finally emitted to the receiver, the receiver receives the digital signals, converts the digital signals into analog signals and output the analog signals to a sound box to make a sound through a USB interface. The USB interface wireless audio emitting receiver adopts wireless connection, facilitating installation and effectively avoiding the disadvantages of the inconvenience of exposed wiring and the interference easily occurring to signals in remote transmission.
Description
Technical field
The utility model relates to wireless transmitting and receiving device, relates in particular to a kind of audio frequency transceiver that adopts USB interface wireless connections stereo set.
Background technology
At present, existing known stereo set, audio signal transmission majority between signal output apparatus and the signal receiver is to connect by holding wire, therefore can adopt open-wire line to connect, can be during wiring because the restriction in place can cause wiring inconvenient, not attractive in appearance, when will carry out long-distance transmissions, signal is disturbed easily, and serious meeting causes distortion.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of audio frequency transceiver that adopts USB interface wireless connections stereo set to be provided.
In order to achieve the above object, the utility model has adopted following technical scheme:
USB interface ANTENN AUDIO transceiver, include USB interface ANTENN AUDIO reflector and USB interface ANTENN AUDIO receiver, reflector is made up of audio signal transmitter module (1) and USB interface (2), audio signal transmitter module (1) is divided into digital signal transmitter module (3) again, signal modulation module (4) and signal conversion module (5), USB interface (1) is inserted main frame, audio signal is transferred to audio signal transmitter module (2) by USB interface (1), carry out the D/A conversion by the signal conversion module in this module (5), digital signal after the conversion is carried out the 2.4G carrier modulation by signal modulation module (4), carrier signal after the modulation is launched by digital signal transmitter module (3), receiver is made up of audio signal receiver module (6) and USB interface (7), audio signal receiver module (7) is divided into wireless signal receiver module (8) again, signal modulation module (9) and signal conversion module (10), when wireless signal receiver module (8) receive transmit after, carry out demodulation by signal modulation module (9), the signal of demodulation carries out the D/A conversion by signal conversion module (10), and the analog signal after the conversion outputs on the audio amplifier by USB interface (7) and sounds.
The utility model is by the wireless connections mode, realize not needing to pass through holding wire between signal output apparatus and the signal receiver, can arbitrarily put, be not subjected to the short restriction of signal line length, quick simple and easy connection, easy for installation, effectively avoided having adopted the inconvenience of surface wiring, and when carrying out long-distance transmissions, the shortcoming that signal is disturbed easily.
Description of drawings
Fig. 1 is the structural representation of the utility model reflector;
Fig. 2 is the structural representation of the utility model receiver;
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, when usb 1 is inserted signal output apparatus, after the energized, audio signal is transferred to audio signal transmitter module 2 by usb 1, carry out the D/A conversion by the signal conversion module in this module 5, digital signal after the conversion is carried out the 2.4G carrier modulation by signal modulation module 4, carrier signal after the modulation is emitted to receiver by digital signal transmitter module 3, as shown in Figure 2, receiver is made up of audio signal receiver module 6 and USB interface 7, USB interface is received on the signal receiver, when wireless signal receiver module 8 receive transmit after, carry out demodulation by signal modulation module 9, the signal of demodulation carries out the D/A conversion by signal conversion module 10, and the analog signal after the conversion outputs on the signal receiver by USB interface 7 and sounds.
The utility model is by the wireless connections mode, realize not needing to pass through holding wire between signal output apparatus and the signal receiver, can arbitrarily put, be not subjected to the short restriction of signal line length, quick simple and easy connection, easy for installation, effectively avoided having adopted the inconvenience of surface wiring, and when carrying out long-distance transmissions, the shortcoming that signal is disturbed easily.
