The present invention relates to a Bluetooth headset, and more particularly, to a Bluetooth headset capable of listening to sound by a stereo speaker and providing a microphone function while improving portability by reducing size.

Since multimedia such as broadcasting phone or PMP phone is embedded as a main function of mobile phone, various contents can be viewed through a mobile phone. This trend is driving the demand for Bluetooth headsets (also known as wireless headsets).

In a typical Bluetooth headset, a speaker portion (hereinafter referred to as a speaker) and a microphone portion (hereinafter referred to as a microphone) are integrally formed. When the speaker and the microphone are integrated into one body, the overall size of the Bluetooth headset is inevitably increased.

This is because even if the speaker and the microphone is integrally provided in one body, the speaker and the microphone need to be spaced to some extent from each other to prevent the howling phenomenon between the speaker and the microphone. Otherwise, when the speaker and the microphone are almost in contact or placed at a short distance, sonic sound, which is a so-called echoing phenomenon, is inevitably degraded.

Despite the above reasons, however, most of them are implemented as mono Bluetooth when a small Bluetooth headset is manufactured by forcibly reducing its size. This is because there is not enough space to mount two or more speakers spaced apart from each other in one body.

On the other hand, in a stereo Bluetooth headset, the overall size of the Bluetooth headset is naturally increased since the speaker and the microphone have a space to form a proper distance between the speakers or a sufficient distance between the speakers. Therefore, the sound may be improved, but it causes another problem that the portability is somewhat weak.

On the other hand, in recent years, the problem of sound quality is also an issue, but in particular, a smaller size Bluetooth headset is required to improve portability.

Accordingly, manufacturers of Bluetooth headsets are making various efforts to make the size of the Bluetooth headset smaller, and active researches on this are being conducted.

However, as mentioned above, when the speaker and the microphone are integrally implemented in one body, it is difficult to implement a small size, and there is a limit in that the stereo sound cannot be heard.

Accordingly, there is a need for the development of a Bluetooth headset capable of listening to sound by stereo speakers and providing a microphone function while reducing its size to meet the current trend.

SUMMARY OF THE INVENTION An object of the present invention is to provide a Bluetooth headset capable of listening to sound by a stereo speaker and providing a microphone function while improving portability by reducing size.

The object is a headset body; A fixed speaker provided at one side of the headset body; A movable speaker provided to be withdrawn from the headset body at a position spaced apart from the fixed speaker; A microphone provided to be withdrawn from the headset body; And a controller configured to control on / off of any one of the movable speaker and the microphone based on a predetermined wireless signal.

Here, the predetermined wireless signal may be any one of a listening mode and a calling mode as a signal provided from a mobile terminal, and the controller may turn on the operation of the movable speaker and operate the microphone in the listening mode. May be turned off, the operation of the microphone may be turned on in the call mode, and the operation of the movable speaker may be turned off.

The fixed speaker may be turned on in both the listening mode and the call mode.

The microphone may be integrally coupled to the dummy body forming the movable speaker, and the dummy body and the headset body may be electrically connected to each other by a predetermined connection line.

The headset body may be provided with a winding drum for winding up and unwinding the connection line.

The headset body may further include a winding button for rotating the winding drum in one direction so that the connection line released from the winding drum may be wound on the winding drum.

The movable speaker and the microphone may be implemented by a single combined device, respectively.

An ear holder may be coupled to the fixed speaker.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in these figures, the Bluetooth headset 10 according to the present embodiment includes a control unit for controlling the headset body 12, the fixed speaker 20, the movable speaker 22, the microphone 24, and a part thereof. 30 is provided.

The headset body 12 is a part forming an appearance in the Bluetooth headset 10 of the present embodiment. Although the Bluetooth headset 10 of the present embodiment has a stereo function, the size of the headset body 12 may be kept small due to the following structural features.

The main button 13 is provided on the front of the headset body 12, and the adjustment button 15 is provided on the side. Selecting, playing, stopping, repeating, rewinding, rewinding a series of listening activities such as listening to a multimedia broadcast or MP3 through the main button 13 and the control button 15 (referred to as a listening mode). , Volume control, etc. can be selected. Of course, various functions may be added in addition to this.

A winding button 16 is further provided around the main button 13. When the winding button 16 is in the state as shown in FIG. 1 by unwinding (unwinding) the connecting line 28 from the winding drum (not shown) provided in the headset body 12, the connecting line 28 is again connected. It rotates the winding drum in one direction so as to be wound around the winding drum.

In other words, the mutually organic operation of the winding button 16, the winding drum, and the connecting line 28 is substantially similar to the operation of the automatic tape measure which is commonly encountered in the periphery. Therefore, the detailed structure and operation of the winding drum will be omitted in the present embodiment, and if necessary, those cited by the present applicant are cited.

The fixed speaker 20 is provided on one side of the headset body 12. Unlike the movable speaker 22, the fixed speaker 20 is fixed to protrude a predetermined length in the upper region of the rear surface of the headset body 12.

The operation of the fixed speaker 20 is turned on both in the above-described listening mode or in the call mode by the mobile terminal 1. Thus, the stereo function can be implemented together with the movable speaker 22 in the listening mode. Of course, in the general call mode performs a normal mono function.

An ear holder 21 is provided around the fixed speaker 20. The ear holder 21 allows the Bluetooth headset 10 to be worn on one ear. The ear holder 21 may be in the form of a ring or may have a ring shape with one side open.

While the fixed speaker 20 is fixed to one side of the headset body 12, the movable speaker 22 is withdrawn from the headset body 12 at a position spaced apart from the fixed speaker 20. That is, although the movable speaker 22 is usually built-in or hangs on the headset body 12 side, the desired length can be secured by pulling from the headset body 12 when necessary.

Of course, the microphone 24 is also provided to be withdrawn from the headset body 12, like the movable speaker 22.

In this embodiment, the microphone 24 is integrally coupled to the dummy body 26 forming the body of the movable speaker 22 so that such an operation can be made (see FIG. 1). And it is electrically connected to the headset body 12 through the above-described connection line 28.

Accordingly, as described above, when the dummy body 26 to which the microphone 24 is coupled is pulled out, the connection line 28 is released from the winding drum provided in the headset body 12, and the microphone 24 and the movable speaker are removed. 22 may be withdrawn from the headset body 12 in a predetermined length. Of course, in order to return the microphone 24 and the movable speaker 22 to their original positions, the connecting line 28 may be wound due to the reverse rotation of the winding drum by pressing the winding button 16.

When implemented in a simple structure as shown in FIG. 1, the connection line 28 may be divided into a portion 28a connected to the movable speaker 22 and a portion 28b connected to the microphone 24, as shown in an enlarged view. It may be. Of course, the control unit 30 is in charge of whether the on / off of the electrical signal operation for these.

1, if it is cumbersome to integrally connect the microphone 24 to the dummy body 26 of the movable speaker 22, the functions of the movable speaker 22 and the microphone 24 may be selectively selected. It is also possible to use a conventional combined device that can be implemented.

The control unit 30 is responsible for controlling the operation of any one of the movable speaker 22 and the microphone 24 on / off based on a predetermined radio signal.

Here, the predetermined radio signal is a signal provided from the mobile terminal 1, as shown in FIG. 2, which is one of a listening mode and a call mode. As described above, the listening mode refers to a series of listening actions such as listening to a multimedia broadcast or an MP3, and the call mode refers to an action of making or receiving a call.

If the radio signal of the listening mode is transmitted from the mobile terminal 1, the controller 30 turns on the operation of the movable speaker 22 and turns off the operation of the microphone 24. Thus, in this state, stereo sound can be enjoyed.

If the radio signal of the call mode is transmitted from the mobile terminal 1, the controller 30 turns on the operation of the microphone 24 and turns off the operation of the movable speaker 22. At this time, it is possible to have a conversation with the microphone 24 while listening to the voice of the other party through the mono mode receiving function by the fixed speaker 20.

The operation of the Bluetooth headset 10 having such a configuration will be described with reference to FIG. 4 as follows.

First, as shown in FIG. 1, the connecting line 28 is pulled and hangs from the headset body 12. FIG. Then, the connecting line 28 is released from the headset body 12 and the movable speaker 22 and the microphone 24 are spaced apart from the headset body 12. In this state, the mobile terminal 1 and the Bluetooth headset 10 are connected by wireless communication (S11).

When the user of the mobile terminal 1 wishes to listen to music, for example, the wireless signal of the listening mode is transmitted from the mobile terminal 1 to the Bluetooth headset 10.

The controller 30 determines whether or not the listening mode is transmitted to the transmitted signal (S13). When the listening mode is confirmed, the controller 30 turns on the operation of the movable speaker 22 and turns off the operation of the microphone 24. (S15). At this time, if the fixed speaker 20 is worn on one ear and the movable speaker 22 is worn on the other ear, stereo sound can be enjoyed.

If the radio signal of the call mode is transmitted from the mobile terminal 1, the controller 30 determines whether the radio signal is present (S23), and if the call mode is confirmed, the operation of the movable speaker 22 is turned off (Off). And the operation of the microphone 24 is turned on (S25). At this time, it is possible to have a conversation with the microphone 24 while listening to the voice of the other party through the mono mode receiving function by the fixed speaker 20.

When the call ends or the operation of listening to music is stopped, the user presses the winding button 16 and returns the movable speaker 22 and the microphone 24 to their original positions.

As described above, according to the present embodiment, since the movable speaker 22 and the microphone 24 are drawn out of the headset body 12 only during use, the Bluetooth headset 10 can be made small in size, thereby improving the portability and the stereo speaker. It is possible to listen to the sound by, and to provide the microphone 24 function.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

In the above embodiment, the description is omitted, but the connection line may have a certain rigidity. This will be convenient to use as a microphone after flipping in the desired direction.

In the above-described embodiment, the movable speaker and the microphone are selectively on / off controlled by the control unit. However, a separate switch is further provided on the headset body to allow the movable speaker and the microphone to be selectively turned on and off. (On / Off) may be used.

Referring to the drawings of the above-described embodiment, the shape of the movable speaker is in the form of the ear, but it may be the same as the fixed speaker.

The winding drum of the above-described embodiment may be provided inside the headset body or may be provided outside thereof. Of course, without the winding drum, it may simply be a form of winding the connecting line on one side of the headset body.

As described above, according to the present invention, it is possible to listen to sound by a stereo speaker and to provide a microphone function while improving portability by reducing size.
