The present invention relates to a wireless headset, and more particularly, in a state of being separated from a mother transmitting a wireless signal, the wireless signal received from the mother is received and converted into sound waves, so that the user is not constrained to the line. The present invention relates to a wireless headset that allows both hands to be used freely while listening to the headset.

In recent years, by using additional sound devices in addition to electronic devices such as mobile phones and MP3s, users can use such devices even without hands on devices such as mobile phones and MP3s. The use of such an acoustic device is attributable to the development of short-range wireless communication technologies such as Bluetooth, Wireless Lan (WLAN), Wireless Personal Area Network (WPAN), and Radio Frequency Identification (RFID).

On the other hand, in the general form of the sound device, in order to fix the mounting position of the sound device, the frame is supported on the aft wheel in a state in which a frame having a structure similar to the aft wheel is provided integrally with or detachable from the sound device. It was used in the form of However, such a structure has a problem in that the user has to wear it through a complicated operation of turning or deforming the frame on his or her ear, and there is a problem that it is not easy to wear it in the correct position. The overall volume of the sound equipment is large, and the hook-shaped shape of the frame is often undesirably caught by an external object such as a bag.

Due to this problem, there is also introduced a product for wearing the acoustic device by the process of inserting the earphone into the ear canal of the user without having to hang the acoustic device on the ear wheels. In this case, the operation of the user wearing the acoustic device is performed in such a way that the earphone of the acoustic device is directly caught by the interval between the user's migration and the other's attention and the internal space of the ear canal.

As a conventional technology of such a wireless headset, a technology such as Korean Utility Model Registration No. 20-0393227 has been proposed. The above-described technology not only allows the wireless headset to be mounted directly on the user's ear, but also allows the earphone to pop out of the wireless headset body when the wireless headset is in use, and the earphone to be recessed in the center of the body when storing the wireless headset. It is operated in such a way as to be inserted into the space of the.

However, this method has a problem in that the mounting space of components mounted inside the wireless headset becomes narrow. In other words, in order to secure the insertion space of the earphones, since a large opening must be formed in the center of the wireless headset body, many of the other parts necessary for the operation of the wireless headset must be placed in a different position out of the opening. The size of the wireless headset is inevitably large for the components to be mounted.

In addition, since the earset directly connected to the earphone is rotated by the hinge in a long state provided, when the user is wearing the wireless headset, the other end of the earset protrudes to the outside, and when another item is caught on the protruding portion of the earset, the wireless The headset will come out of the ear.

In addition, since the force to be pushed in one direction is always applied to the earphone by the torsion spring, there is a problem that the earphone is pushed outward even by a weak external shock. Therefore, the wireless headset becomes difficult to operate normally.

In addition, since the earphone is located inside the main body, there is a problem in that drawing and drawing are not easy.

As a conventional technology that has been proposed to improve this inconvenience, Korean Patent Application No. 10-2005-0113925, the name of the invention "wireless headset" that has already been patented by the applicant of the present invention can be illustrated. have.

The "wireless headset" is composed of a main body, earphones, earphone position guide structure, and by the structure as described above, the earphone is withdrawn or withdrawn or with respect to the main body between the stop state and the withdrawal state Characterized in that the position is maintained.

The above configuration has the advantage that the wireless headset can be stably operated, the device can be operated normally, and can be stably placed in a given position and structure at a location indicated by an unconscious external shock.

However, such a conventional "wireless headset" has the following problems.

First, since the conventional wireless headset only protrudes to the outside, the earphone had to be directly rotated in order to use the wireless headset. However, since the earphone is made of a soft material, when the user's hand is wet, there is a problem that the rotation of the earphone is not easy.

In addition, in the conventional wireless headset, since the earphone position guide structure of the earphone is formed inside the main body, there is a problem that the user is interfered by the main body when operating the earphone.

The present invention has been proposed to solve the above problems, the wireless headset is easily mounted on the ear, the wireless headset can be easily attached and detached, even when given an external impact can be placed stably in a predetermined shape and structure at a predetermined position. An object of the present invention is to provide a wireless headset.

In addition, since the spacer protrudes to the outside, and the earphone is drawn out only by pressing the protrusion of the spacer, an object of the present invention is to provide a wireless headset which is easier to use.

In addition, the rotation axis of the earphone is coupled to the rotary guide portion formed in the upper front in the main body so that the rotation center of the earphone further separated from the main body, thereby preventing interference between the spacer and the rotation guide part, and easy to operate a wireless headset It aims to provide.

In addition, it is an object of the present invention to provide a wireless headset which is small in size, easy to store and carry by the user, easy to operate by the user, and improved in operation reliability.

In addition, the wireless headset is closely coupled to the user's ear, so that the wireless headset is not removed even if the external shock is applied during the use of the wireless headset, to provide a wireless headset with improved operation reliability and product durability. do.

Each of the circuits is preferably provided on a predetermined substrate (see 12 in FIG. 3) placed inside the body 2.

The earphone 6 has a speaker device for reproducing an electric signal as an acoustic signal by vibration of air. In addition, a flexible member is formed at the end of the earphone 6, so that the insertion member is softly deformed when the insertion member is inserted into the user's ear so that the insertion state can be firmly maintained. Therefore, there is no need for any frame of similar shape and form to the wheels for the wireless headset 1 to be mounted on the ear.

Thus, the earphone 6 and the spacer 7 coupled thereto are provided at the end of the main body 2 provided in the long rod shape, so that the user can see the earphone 6 or the spacer ( It is possible to easily withdraw the earphones 6 to make the wireless headset 1 in use state only by recognizing 7) as a tactile sense and drawing them outward.

By the above structure, the user operates the earphone 6 or the spacer 7 with the fingers of the hand holding the main body 2 while holding the main body 2 with one hand. The headset 1 can be operated conveniently.

3 is a cross-sectional view taken along line II ′ of FIG. 1, and FIG. 4 is a partial cutaway front view of FIG. 1.

The wireless headset 1 according to the present invention is characterized in that the state of movement of the earphone 6 is conveniently provided. Hereinafter, the configuration related thereto will be described in more detail.

3 and 4, the connection portion between the earphone 6 and the main body 2 includes a spacer 7 that provides a predetermined length of distance between the earphone 6 and the main body 2. do. In addition, the main body 2 is provided with an earphone seating surface 8 for guiding the mounting position of the earphone 6.

In detail, a rotation guide part (see 24 of FIG. 2) is formed at an upper end of the main body 2 to protrude forward to guide the rotational movement of the earphone and the spacer. In addition, a hinge coupling hole to which the hinge assembly 30 to be described later is coupled is formed inside the rotation guide part.

In detail, the spacer 7 catches the user's ear when the earphone 6 is pulled out in the state of use of the wireless headset 1 so that the earphone 6 is inserted into the ear of the user. This is to prevent interference by mounting by causing interference. In other words, when the wireless headset 1 is caught by the user's ear by the spacer 7, a distance of a certain distance between the user's ear and the main body 2 is maintained.

In addition, the spacer 7 is based on the hinge assembly 30 to be described later, the earphone 6 is coupled to one side, the pressing portion 25 is protruded on the other side. Therefore, the user may allow the earphone 6 to be drawn out to the outside only by pressing the pressing portion 25 protruding to the outside.

In detail, the earphone seating surface 8 provides a seating position of the earphone 6 when the earphone 6 is stored in a state adjacent to the main body 1 in the storage state of the wireless headset 1. For this purpose, it is a part which is recessed in the inner direction of the main body 2 of a long rod shape.

On the other hand, the earphone 6 is provided in a state capable of hinge rotation with respect to the main body 2, the earphone 6 is capable of hinge rotation, while the earphone 6 is guided and accommodated in the earphone guide groove 8 The position of the state and the position of the state where the earphone 6 is drawn out are guided correctly.

On the other hand, by the locking end 22 formed in the main body 2 and the locking portion 21 formed in the spacer 7, the earphone 6 and the spacer 7 flipped back toward the withdrawal state are rearward. It can further play the role of being fixed exactly in place without going further.

Hereinafter, the earphone position guide structure for guiding the position of the earphone 6 will be described in detail.

Earphone position guide structure according to the present embodiment is a structure similar to the hinge structure for the rotation of the folder of the folder-type mobile phone, the hinge assembly 30 is formed in the connection portion of the spacer 7 and the rotation guide portion 24.

First, the structure of the hinge assembly 30 will be described in detail.

The hinge assembly 30 according to the present invention is fixed to the hinge case 31 forming an outer shape of the hinge assembly 30 and one side of the hinge case 31 to operate the hinge assembly 30. An elastic member 32 providing an elastic force, a first cam 33 coupled to the other side of the elastic member 32 to guide the operation of the hinge assembly 30, and the first cam 33; The second cam 34 is formed to be engaged, and the rotary shaft 35 is integrally formed with the second cam 34 and coupled to the spacer 7.

In detail, the hinge case 31 is formed in a hollow cylindrical shape with one side open. In addition, a fixing jaw is formed at an opened side of the hinge case 31 such that the second cam 34 is not separated from the hinge assembly 30.

In detail, an elastic member 32 is coupled to one side of the hinge case 31, and a first cam 33 having a substantially triangular pyramid shape is coupled to the other side of the elastic member 32. In addition, the other side of the first cam 33, the second cam 34 of the shape corresponding to the first cam 33 and the rotary shaft 35 formed integrally therewith are coupled. In more detail, the second cam 34 is coupled to compress the elastic member 32 coupled to the first cam 33. Accordingly, the elastic member 32 always provides an elastic force in the direction in which the length thereof extends, that is, the left to right direction when viewed in the drawing.

In detail, the rotation shaft 35 may be formed in a substantially square shape. The diagonal length of the square is preferably equal to the diameter of the coupling hole 23 formed in the spacer 7. By the above configuration, the rotary shaft 35 is matched with the coupling hole 23, so that the spacer 7 and the rotary shaft 35 can be rotated together without turning.

Next, the coupling process of the hinge assembly 30, the main body 2 and the spacer 7 will be described.

First, a hinge coupling hole is formed inside the rotation guide part 24 extending upward from the upper left / right side of the main body. The hinge coupling hole is formed at an upper end of the rotation guide part 24 extending upwardly from the main body. Therefore, the hinge coupling hole and the hinge assembly 30 coupled thereto are placed in a position biased to one side with respect to the extending direction of the main body. By such a configuration, the rotation center of the earphone is further spaced apart from the main body, thereby preventing the interference acting on the earphone.

In addition, the hinge assembly 30 formed integrally is inserted into the hinge coupling hole and accommodated therein. In this state, when the rotary shaft 35 projecting outward is pressed, the second cam 34 integrally formed with the rotary shaft 35 presses the first cam 33 which is in contact with it, and thus the elastic member 32 is By being compressed, the rotating shaft 35 may be drawn into the hinge case 31. In this state, when the spacer 7 is inserted between the rotation guide portions 24 on both sides of the main body 2, the rotation shaft 35 is returned to its original position by the elastic force provided by the elastic member 32, thereby providing the spacer ( The rotating shaft 35 is coupled to the coupling hole 23 of 7).

In this case, the rotation shaft 35 is formed to fit with the coupling hole 23 of the spacer 7, when the spacer 7 is rotated, the rotation shaft 35 and the second cam 35 integrally formed therewith. It must be formed to rotate together.

By the structure as described above, the first cam 33 is always provided with a force in the direction pushing toward the second cam 34 from the elastic member 32. That is, the first cam 33 provides a force for the second cam 34 to be placed at a constant rotational angle while always in contact with the second cam 34.

In other words, the position where the spacer 7 and the earphone 6 coupled thereto are stabilized by the interaction between the first cam 33 and the second cam 34 is such that the earphone 6 is located in the stable state. The wireless headset 1 may be in a state in which the wireless headset 1 is not used as the state accommodated in the earphone seating surface 8 or the earphone 6 is completely drawn outward. And in the center position, since the 2nd cam 34 is in an unstable position, it always provides the force which rotates to either side.

When the wireless headset 1 is not operated by the position guide structure of the earphone, that is, when the earphone 6 is accommodated inside the earphone seating surface 8, a certain amount of external force is not applied. Otherwise, the earphone 6 is not drawn outward by the interaction of the first cam 33 and the second cam 34. Therefore, it can be expected that the earphone 6 is not drawn out even by the impact applied from the outside in the state where the wireless headset 1 is accommodated in the pocket or bag. By this structure, the hygiene state of the earphone 6 is improved, the convenience of use is improved, and the operation stability of the wireless headset 1 can be expected to be increased.

In addition, even when the earphone 6 is completely drawn outward, if the external force is not applied to a certain degree, the earphone 6 is inward due to the interaction between the first cam 33 and the second cam 34. It does not come in. Therefore, when the earphone 6 is mounted on the user's ear while being drawn out and in use, the earphone 6 is not easily drawn out by an impact applied from the outside. There is an advantage to be improved.

With reference to the above-described structure will be described in more detail the operation to action according to the present invention.

3 to 8 are diagrams illustrating the inlet and withdrawal operation of the earphone in the wireless headset according to the present invention. FIGS. 3 and 4 are side cross-sectional views and partial cutaway front views of the retracted state, and FIGS. 5 and 6 are retracted views. A side cross-sectional view and a partial cutaway front view of a state in which a drawing operation is performed, and FIGS. 7 and 8 are side cross-sectional views and a partial cutaway front view of a withdrawn state.

3 and 4, the state in which the wireless headset 1 is retracted and waiting for use will be described.

In the state where the wireless headset 1 is in use, the earphone 6 is accommodated in the main body and is accommodated in the earphone seating surface 8. Further, even if the earphone 6 is caught by another item of the outer world, since the position is stably supported by the earphone position guide structure as described above, the earphone 6 is not drawn outward. Due to such a stable structure, it is possible to obtain an advantage that the operational stability of the wireless headset 1 is improved.

5 and 6, a process of pulling in / out of the wireless headset 1 will be described in detail.

When a call comes to a mobile phone or the like and the user wants to use the wireless headset 1, the user rotates the earphone 6 to draw it to the outside. Referring to the withdrawal process of the earphone 6 in more detail, the user pushes up a portion of the earphone 6 protruding to the outside of the earphone seating surface 8 with the hand holding the main body 2. Or press the protruding portion near the locking portion 21 of the spacer (7). Then, the earphone 6 is rotated about the rotation shaft 35, the earphone 6 is lightly rotated by the interaction of the first cam 33 and the second cam 34 is drawn outward. do.

In other words, until the user exerts an external force to a certain degree or more and the center of gravity of the earphone 6 exceeds the reference axis 40, when the user removes the external force, the earphone 6 returns to the retracted state. However, once the center of gravity of the earphone 6 exceeds the reference axis 40, even when the user removes the external force, the earphone 6 rotates in the drawn state by the interaction of the first cam 33 and the second cam 34. do.

In this way, since the earphone 6 can be drawn outward lightly, the user's convenience can be further improved. Then, once the earphone 6 is withdrawn, the earphone 6 has the first cam 33 and the second cam until the earphone 6 is pulled inward with the same force as when the user withdraws it. It is fixed at the drawn out position by the force acting between 34). Therefore, even when the user inserts the earphone 6 into the ear, the earphone 6 can be accurately maintained in the withdrawal position without shaking. Therefore, the inserting operation of the earphone 6 can be made more accurately and conveniently.

In addition, since the spacer 7 extends beyond a predetermined length in the state in which the earphone 6 is drawn out, the main body 2 is formed in the outer structure of the ear, such as the auricle, in the state where the user inserts the earphone 6 into the ear. Does not cause interference. Therefore, the insertion position of the wireless headset 1 can be kept more firm and stable. The length of the spacer 7 can be formed to a length suitable for the purpose as described.

In addition, since the rotation path of the spacer 7 is guided by the rotation guide part 24, and the maximum rotation radius is limited by the locking part 21 and the locking end 22, external shock is applied to the spacer 7. Even if it loses, there is an advantage that the earphone 6 is prevented from being damaged. In other words, since the spacer 7 and the rotation guide 24 correspond to each other, even if an external shock is applied to the earphone 6, the amount of impact applied to the hinge assembly 30 is significantly reduced. It can be. Of course, the withdrawal and withdrawal operations of the spacer 7 are guided by the rotation guide 24.

7 and 8, the state in which the wireless headset 1 is drawn out and in use will be described.

As described above, the state in which the earphone 6 is in use is a state in which the earphone 6 is completely drawn out, and the center of gravity of the earphone 6 crosses the reference axis 40. Therefore, the earphone 6 is in the direction in which the earphone 6 is drawn out, ie clockwise when viewed in the drawing, by the interaction of the elastic member 35 and the first cam 33 and the second cam 34. Get the force to rotate. Therefore, since the earphone 6 can maintain the drawn state even when subjected to an external force of a certain degree or less, there is an advantage that the operational stability is increased.

On the other hand, the earphone 6 and the spacer 7 is supported so that it is no longer flipped back by the locking portion 21 and the locking end 22.

In addition, after the earphone 6 is completely withdrawn, the user may start the operation of the wireless headset 1 by operating the on / off button 10, or after use, the on / off button 10 Press again to end use of the wireless headset 1. And, of course, when the volume is to be adjusted during use, the volume can be adjusted by the volume control unit (4). Furthermore, the wireless headset 1 may be operated in the operation state only by the operation of pulling out the earphone 6 without the need of separately operating the on / off button 10 after the earphone 6 is completely drawn out. For example, the wireless headset 1 may be automatically brought into operation by detecting the extraction position of the earphone 6.

When the use of the wireless headset 1 is terminated and the user wants to pull the earphone 6 inward, the user may rotate the earphone 6 inward as opposed to the pulling out operation of the earphone 6. Detailed description will be omitted.

According to the present invention, the wireless headset is easily mounted on the ear, the wireless headset can be easily attached and detached, and even when an external shock is applied, the wireless headset can be stably placed in a predetermined shape and structure at a predetermined position, and the size of the product is reduced, and the user It is possible to obtain advantages of easy storage and carrying, easy operation of the user, and improved operation reliability.

Therefore, in the description of the present embodiment, the part without description thereof will use the description of the first embodiment, and detailed description thereof will be omitted. In addition, in the drawing numbers, the same components as in the first embodiment will be denoted by the same reference numerals to be described.

9 to 12 are diagrams illustrating the retracting and withdrawing operation of the earphone in the wireless headset according to the second embodiment of the present invention. FIGS. 9 and 10 are side cross-sectional views and partial cutaway front views of the retracted state, and FIG. 11. 12 is a side cross-sectional view and a partial cutaway front view in the drawn state.

9 to 12, in the wireless headset 1 according to the second embodiment of the present invention, as compared with the first embodiment, the engagement angle of the rotational axis 35 of the hinge assembly 30 is characteristically different. In other words, the coupling angle of the rotary shaft 35 is adjusted so that the reference shaft 50 is positioned in a direction rotated by a predetermined angle clockwise as compared with the first embodiment.

Therefore, the spacer 7 to which the earphone 6 is coupled always receives a force in a direction in which it is drawn, that is, counterclockwise when viewed in the drawing. In other words, since the center of gravity of the earphone 6 does not exceed the reference axis 50 until the rotation of the spacer 7 is limited by the locking portion 21 and the locking end 22. In other words, it always receives the direction of the incoming direction.

With reference to the above-described structure will be described in more detail the operation to action according to the present invention.

When a call comes to a mobile phone or the like and the user wants to use the wireless headset 1, the user rotates the earphone 6 to draw it to the outside. Referring to the withdrawal process of the earphone 6 in more detail, the user pushes up a part of the earphone 6 protruding to the outside of the earphone seating surface 8 with the hand holding the main body 2. Alternatively, pressing the protruding portion near the locking portion 21 of the spacer 7 causes the earphone 6 to rotate about the rotation shaft 35. Then, the user pushes up the earphone 6 or inserts the earphone 6 into the ear while pressing the protruding portion near the locking portion 21. When the earphone 6 is inserted and the user releases his or her hand holding the wireless headset 1, the main body 2 is centered around the earphone 6 and the spacer 7 inserted into the user's ear. Is rotated toward the user's ear and tightly coupled to the user's earlobe or the like.

In other words, since the earphone 6 is always subjected to a force to be rotated in the retraction direction by the elastic force provided by the elastic member 35, the earphone 6 in the state where the earphone 6 is inserted into the ear canal of the user. It is tightly coupled to the user's ear.

By the structure as described above, the earphone is closely coupled to the user's ear, even when an external shock is given, it can be stably placed in a predetermined shape and structure at a predetermined position, the operation reliability and durability of the product is improved.

According to the configuration of the present invention as described above, the wireless headset is easily mounted on the ear, the wireless headset can be easily attached and detached, and even when an external impact is provided, there is an effect that can be stably placed in a predetermined shape and structure at a predetermined position. .
