Abstract

The utility model discloses a wireless earphone, which comprises a playing conversion device formed by the connections between a playing conversion switch (4) respectively with an audio power amplifying module (5) and an earphone loud-speaker (3) as well as between the audio power amplifying module (5) and a power amplifying loud-speaker (6), and a wireless connecting device which comprises the connections between a Bluetooth emitting module (7) and a music player as well as between a blue tooth receiving module (8) and the playing conversion switch (4). The sound playing part formed by the audio power amplifying module and the power amplifying loud-speaker can keep normal sound listening when the earphone is picked off caused by tired ear; the Bluetooth receiving module of the wireless earphone part of the utility model can be directly matched with the other apparatuses with Bluetooth emitting modules to be used so as to realize wireless playing.

Description

A kind of wireless headset

Technical field

The utility model relates to a kind of wireless headset, especially a kind of wear-type wireless headset.

Background technology

People are when music appreciating, often in order to obtain the good sound quality effect, particularly when using portable music player, the capital selects earphone as sound generation source, simultaneously, in order further to overcome the constraint of earphone sound source wire to service range, wireless headset becomes the optimal selection of modern people's enjoy music especially.

During but existing earphone uses there be the main problem that exists:

After long wearing headphones, inevitably can cause ear's pain and tired out, even the hearing of damage ear-drum, but will interrupt appreciation again, so brought great inconvenience to use to music if take the suitable rest of earphone.

In addition, the transmitter module of conventional wireless earphone and receiver module need supporting use, so its wireless poor compatibility.

The utility model content

In view of the above deficiency of prior art, the purpose of the utility model design is: providing a kind of can play the wireless headset of conversion between the two in earphone broadcast and sound equipment, and the wireless compatibility of this wireless headset be strong according to actual needs.

For achieving the above object, the utility model has adopted following technical scheme:

Design and a kind ofly can change the wireless headset that earphone is play and sound equipment is play, it is except the parts that comprise the headstock, earmuff, earphone speaker earphone and generally possess, and it also comprises plays conversion setting and wireless connection device;

It is play the conversion setting and constitutes by playing change over switch, audio frequency power amplifier module and power amplifier loud speaker, playing change over switch is connected with earphone speaker with audio frequency power amplifier module respectively, audio frequency power amplifier module is connected with the power amplifier loud speaker, and audio frequency power amplifier module becomes sound equipment to play part with the power amplifier set of speakers;

Its wireless connection device comprises Bluetooth transmission module and bluetooth receiver module, the Bluetooth transmission module is connected with music player, the bluetooth receiver module is connected with the broadcast change over switch, and the sound source signal that the bluetooth receiver module can spread out of the Bluetooth transmission module receives and passes to the broadcast change over switch.

Above-mentioned power amplifier loud speaker is arranged on the outside of earmuff.

During use, regulate and play change over switch, just the sound source signal that the bluetooth receiver module can be received switches broadcast between power amplifier loud speaker and earphone speaker, can take off this wireless headset when sensation ear is tired out, regulates the broadcast change over switch and gets final product to the power amplifier loudspeaker plays.

The beneficial effects of the utility model are:

Owing to be provided with the sound equipment broadcast part that audio frequency power amplifier module and power amplifier loud speaker are formed, realize the sound equipment broadcast so can substitute the fixed combination sound equipment, not only having dwindled the use volume is beneficial to and carries, also reduced power consumption, and make because long-time wearing headphones when causing ear tired out, can both continue maintenance at any time and normally listen to sound after taking off earphone; In addition, existing a lot of electronic products, as: notebook computer, mobile phone etc., itself just carries Bluetooth function, contain the bluetooth sending module, because reception, the sending module of bluetooth all are to adopt unified connection standard, are compatiblely to match, so the bluetooth receiver module of the utility model wireless headset part then can also directly use with more coordinative composition of equipments that other self has the Bluetooth transmission module.

Embodiment

Below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.

Shown in Fig. 1,2,3,4.

The earmuff (2) that wireless headset comprises the headstock (1) and is connected with at its two ends, earmuff (2) is built-in with earphone speaker (3).

This wireless headset also is provided with 1 broadcast change over switch (4), 1 audio frequency power amplifier module (5), 2 power amplifier loud speakers (6) and 1 group of bluetooth reception, sending module and constitutes;

Bluetooth receiver module (8) is connected with broadcast change over switch (4), playing change over switch (4) is connected with earphone speaker (3) with audio frequency power amplifier module (5) respectively, audio frequency power amplifier module (5) is connected with power amplifier loud speaker (6), and this circuit part is embedded in earmuff (2);

The signal input circuit end of Bluetooth transmission module (7) is connected with signal gang socket (9), and this circuit part is arranged on separately in the independent box body;

Its 2 power amplifier loud speakers (6) are separately positioned on the outside of the headstock (1) two ends earmuffs (2), play the top that change over switch (4) is arranged on left side earmuff (2) power amplifier loud speaker (6).

During use, the signal attachment plug of music player is linked into signal gang socket (9) with Bluetooth transmission module (7), opens the power supply that respectively uses equipment, just can realize wireless listening to; Simultaneously, can also when needs are had a rest, take off this wireless headset, will play change over switch (4) and be adjusted to power amplifier loud speaker (6) and play, realize that continual continuation realization music listens to.

Obviously, when actual production, can also make more embodiment with reference to basic design scheme of the present utility model:
