Description

A kind of audio converter

Technical field

The utility model relates to a kind of transducer, is meant a kind of conversion equipment that is applied in the audio signal transfer process especially.

Background technology

As everyone knows, along with digital product enters the live quickening of speed of people, people's quality of the life has had significant lifting, and especially the appearance of voice playing class digital product is such as portable CD, MD, MP3, and this class digital product has enriched people's life greatly.The earphone series products is a kind of electro-acoustic conversion device, and its cardinal principle is that the electrical signal conversion with sound becomes voice signal.Dual track, multi-channel system are arranged in the prior art, though it has tangible acoustic image to distribute, they launch on a line or a plane, one completely stereophonic sound system should be a kind of three-dimensional surround-sound system that comprises.

Progress along with society, the increasing digital series products that can play the storage convert audio signals constantly appears in people's the life, such as, present most user gets used to some audio files are stored in the computer, circumscribed USB socket by computer when needs are play is finally played back by earphone by the audio converter conversion, afterwards, occurred having the earphone of earphone microphone structure again, it not only can playing audio signal but also the sound of outside can be passed in the computer by microphone.And aforesaid its sound line of earphone with earphone microphone structure generally all comprise earphone about two loudspeaker (SPK-L and SPK-R), earphone system ground wire (GND) and microphone (MIC), microphone system ground wire (GND), this class circuit is opened SPK-R, SPK-L, GND and MIC, GND branch two female seats and is carried out input and output in the accessing to audio transducer, such design is complicated greatly whole sound line, and this is the major defect for conventional art.

Summary of the invention

The utility model provides a kind of audio converter, it is connected with four utmost point contact female plug seats, this four utmost points contact female plug seat has the function of earphone left horn, earphone right horn, microphone and four contacts of system's ground wire simultaneously, so utilize the simulated audio signal of the decoded earphone left horn of this audio converter of the present utility model, earphone right horn, microphone and system's ground wire all to pass through this female plug seat output of four utmost points contact or input, thereby simplify overall structure greatly, and this is to be main purpose of the present utility model.

The technical scheme that the utility model adopted is: a kind of audio converter, it comprises the USB input interface, four utmost point contact female plug seats and digital audio conversion sound card, the utility model when in use, this USB input interface is connected in the USB socket of computer, information in this computer is transferred in the transducer of the present utility model by this USB input interface, this four utmost points contact female plug seat is corresponding with headset plug, the user can be plugged on headset plug in this four pole socket, in order to receive the audio signal of also changing by this transducer of the present utility model from this computer, this digital audio conversion sound card connection is arranged between this USB input interface and this four utmost points contact female plug seat.

This USB input interface, this four utmost points contact female plug seat and this digital audio conversion sound card are set on the substrate respectively, and integral body is set in the internal mold, this internal mold has inner chamber, further, this internal mold is set in the external mold, this external mold has side openings and sleeve, and this USB input interface stretches out this external mold from this side openings of this external mold, and this four utmost points contact female plug cover for seat is located in this sleeve.

This digital audio conversion sound card comprises change-over circuit, utilizes this change-over circuit the digital audio and video signals that is come by transmission in this USB input interface can be decoded, and converts analog stereo audio output and microphone input signal to.

This audio converter of the present utility model is connected with four utmost point contact female plug seats, and this four utmost points contact female plug seat has the function of earphone left horn, earphone right horn, microphone and four contacts of system's ground wire simultaneously.Utilize the simulated audio signal of the decoded earphone left horn of this audio converter of the present utility model, earphone right horn, microphone and system's ground wire all to pass through this female plug seat output of four utmost points contact or input.

The beneficial effects of the utility model are: because the utility model comprises the USB input interface, four utmost point contact female plug seats and digital audio conversion sound card, this digital audio conversion sound card connection is arranged between this USB input interface and this four utmost points contact female plug seat, this USB input interface, this four utmost points contact female plug seat and this digital audio conversion sound card are set up respectively and are connected on the substrate, and integral body is set in the internal mold, this internal mold is set in the external mold, this USB input interface stretches out in this external mold, utilize the decoded earphone left horn of this audio converter of the present utility model, the earphone right horn, the simulated audio signal of microphone and system's ground wire all passes through four female plug seat output of utmost point contact or inputs, thereby simplifies overall structure.
