Abstract

The utility model discloses a pair of wireless headsets. The wireless headsets mainly comprise an audio relay forwarding part and an audio receiving part, wherein the audio relay forwarding part is used for carrying out carrier transmission on received audio, and multiple users can simultaneously use the audio receiving part for receiving audio. According to the wireless headsets, the winding of lines of wired headsets is avoided, the audio can be received within a larger range moveably, and in addition, the audio can be simultaneously received by multiple users.

Description

A kind of wireless headset

Technical field:

The utility model relates to a kind of earphone, relates in particular to a kind of wireless headset that in certain space, can realize the same time listening to audio of many people.

Background technology:

At present, known earphone can only be realized the listening to audio of a pair of same form, or through the earphone tap, realizes that limited number listens to (usually not can greater than 3 people).This has fundamentally limited same audio frequency, and many people of same time listen to.Moreover, most earphone all is the mode through wired connection, realizes the transmission of audio frequency, so not only may make to twine with other line, also can limit listener in scope of activities of listening to even action degree.

Number of patent application is 201120107894.6 to disclose a kind of tv wireless earphone, but its complex structure, and only support four channels.

Summary of the invention:

The technical problem that the utility model will solve is: for overcome existing earphone tap branch very little, the winding of line, the deficiency of distance.The utility model provides a kind of wireless headset, and this earphone can be realized wireless mobile simultaneously the listening to of many people, brings freely to the user and enjoys.

The utility model solves the technical scheme that its technical problem adopted:

A kind of wireless headset is characterized in that said wireless headset comprises: comprise carrier transmit module and receiver module, said carrier transmit module; Be arranged in the miniature space, can regulate tranmitting frequency continuously, said receiver module; Can pass through man-machine interface, regulate receiving channels continuously.

Wherein said carrier transmit module is carried out carrier transmit to the audio frequency that will listen to; Adopt triode, inductance, electric capacity waveform; Audio signal is loaded into above the waveform launches through built-in aerial, can realize continuous adjustable tranmitting frequency, can remember the frequency of last adjusting; The COBBAIF input telescopic folding of said carrier transmit module is connected as a single entity with the carrier transmit module.

The Audio Signal Processing that wherein said receiver module adopts Audio Processing chip TEA5767 that antenna is received; Realize wireless listening to audio, designed the MCU microcontroller, the control and treatment audio signal; Can be manually and automatically switching channels; Design man-machine interface, friendly carried out the man-machine communication, had the man-machine interface that keyboard adds LCD combining form.Have the auto channel search function, and the corresponding channel that also has the last use of memory with transmitter module.

The beneficial effect of the utility model is: can realize the wireless listening to audio of many people, it is adjustable continuously to transmit and receive channel, and receiving channels has automatic function of search, makes simply, and man-machine interface is friendly, and easy operating uses.

The sub-rotating shaft of 1. audio input ends among Fig. 3,4,5,2. audio input end, 3. frequency modulation button, 4. mains switch;

5. rubber ears are taken among Fig. 6,7, and 6. ear is taken draw-in groove, and 7. ear is taken rotating shaft, 8. reset key, 9. manual frequency modulation key upwards, 10. automatic frequency adjustment key, 11. power keys, 12. earphones, 13. audio output jacks, 14. earphones, 15. manual frequency modulation keys downwards.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

In Fig. 1 instance schematic diagram; Lithium coin cells E1 mains switch S1 power filtering capacitor C1, the sub-P1 audio frequency of C2 audio input end filter capacitor C3 triode Q1, resistance R 3, R4, R5, tunable capacitor C4, C5, C6, C7, C8, C9 and controllable impedance L1 form the vibration carrier circuit; For the sound carrier of P1 input, launch through antenna then; In Fig. 2, the audio signal of TEA5767 Audio Processing chip reception carrier emission, microcontroller MCU connects 1,2 pins through the IIC interface and reads control TEA5767 processing audio, finally on pin 7,8, outputs to the left and right acoustic channels of earphone.

In carrier transmit module instance shown in Figure 3, audio input end (2) folds into through rotating shaft (1) when not using, attractive in appearance, light, protection audio input end.Produce during use and insert in the audio jack, turn on the power switch (4), regulate channel button (3), avoid local radio station channel.

In Fig. 6, the instance of receiver module shown in 7, ear is taken (5) and is hung on the ear, listening to audio; Mains switch (11) is arranged above, and man-machine interface is by reset key (8), manually frequency modulation key (9), (15), and automatic frequency adjustment key (10) and LCD channel show, an earphone (12), the second audio track output plughole (13).

Like Fig. 3,4, shown in 5, the concrete steps that the utility model is realized are following:

1. fold audio input end (2) of carrier transmit module, insert in the audio jack;

2. open carrier transmit modular power source switch, default channel can pass through frequency modulation button (3) for the last channel that uses of memory, switches other channels, as long as avoid local radio station channel;

3. there is draw-in groove (6) the receiver module both sides; When receiver module is worn over left ear, can the rubber ear be taken and the rotating shaft that connects is stuck in as among Fig. 2, when being worn over auris dextra; Be stuck in opposite side, can the earphone of opposite side be extracted in audio output jack (13) when only needing an ear to listen to;

4. open the receiver module mains switch, default channel is the last channel that uses of memory.During switching channels, select the adjusting pattern through button (8): manual adjustments or adjusting automatically, manual adjustments are each certain frequency that increases or reduce, and automatic adjusting promptly can search the next effectively channel that increases progressively through button (10) automatically.The best is: search earlier target channel manual fine-tuning more automatically.When display screen LCD arrives the peak frequency of 85～108M when search, need button (8) reset key, switch to from the beginning search about low-limit frequency 85M.

Should be understood that; Above-mentioned description to embodiment is comparatively detailed; Can not therefore think restriction to the utility model scope of patent protection; Variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection range of the utility model.
