Therefore, when the cover portion 21 is rotated, the cam 41 is rotated via the cam rotation shaft 42. In addition, since the cam 41 is made in a non-circular shape and is pushed up by the stud 43, the cam 41 provides a force to always move the cover portion 21 to a constant position.

By the interaction of the cam 41 and the stud 43, the position in which the lid 21 is placed in a stable state is that the lid 21 is completely open or completely closed, In the position, since the cam 41 is in an unstable position, a force that is always rotated in any one direction is provided.

Due to the cover portion guide structure, when the cover portion 21 of the sound device 1 is in a closed state, the cam 41 and the stud 43 may interact with each other when a certain amount of external force is not applied. By the cover portion 21 is not opened. That is, since the cover portion 21 is not opened by an impact applied from the outside in the state where the acoustic device 1 is accommodated in the pocket or the bag, the earphone 6 may be expected to be not drawn out. By such a structure, the hygiene state of the earphone 6 is improved, the user's convenience is improved, and the operational stability of the acoustic device 1 can be expected to be increased.

On the other hand, the earphone position guide structure and the cover portion position guide structure is connected to each other by a stopper (Stopper). By this structure, when the cover portion 21 is opened in the state in which the earphone 6 is retracted, the earphone 6 is automatically rotated to the retracted state.

Hereinafter, a structure of a stopper part connecting the earphone location guide structure and the cover part position guide structure to each other will be described in more detail.

First, a rack 46 is coupled to the side of the cam 41 to deform the rotational movement of the cam 41 to linear movement. In addition, a pinion 47 is formed at a lower portion of the rack 46 to engage with the rack 46 to deform a linear motion into a rotational motion, and the pinion 47 has a pinion rotation shaft 48 formed at the main body. The position is fixed and supported.

On the other hand, in the lower part of the pinion 47, a rack-shaped first stopper 51 for transforming the rotational motion into a linear motion is formed. The first stopper 51 interacts with the cam 41, the rack 46, and the pinion 47 when the cover part 21 is opened or closed, and extends in the extending direction of the main body 2. By moving back and forth in the vertical direction, it serves to provide the supporting force or to remove the provided supporting force.

Preferably, the rack 46, pinion 47, pinion rotation shaft 48 and the first stopper 51 is integrally coupled to the gear box 56, the gear box 56 is a gear box fastening member It is coupled to the main body 2 by 57. By the structure as described above, the manufacturing process can be simplified, the bonding between the components can be secured, and the durability of the product can be obtained.

On the other hand, a second stopper 52 is formed between the first stopper 51 and the catching part 33 to temporarily provide the support force to the catching part 33 when the earphone 6 is pulled out. Perform the function (as detailed in Figure 4).

Referring to FIG. 4, the second stopper 52 is coupled to the main body 2 at one side of the main body 2 and between the main body 2 and the second stopper 52. The stopper side elastic member 53 is connected.

By the structure as described above, the second stopper 52 is always provided with a pushing force from the main body 2 toward the locking portion 33. In addition, in the above-described structure, in the process of closing the cover part 21 again after the user opens the cover part 21, inserts the earphones 6 in order to terminate the use of the audio device 1, The second stopper 52 serves to prevent the earphone 6 from being rotated and pulled out temporarily until the first stopper 51 supports the locking part 33. box)

5 is a rear view of the acoustic apparatus according to the present invention.

Referring to FIG. 5, the cover part 21 and the main body 2 are coupled by the cover part coupling protrusion 22. Then, the cam 41 and the cam rotation shaft 42 is coupled to one end of the cover portion engaging projection 22 inserted into the main body 2. By the above structure, when the user opens and closes the cover part 21, the cam 41 and the cam rotation shaft 42 are integrally rotated with the cover part 21.

On the other hand, preferably, the rack 46 connected to the cam 41, the pinion 47 formed in the lower portion of the rack 46 to rotate in engagement with the rack 46 and the pinion rotation shaft for supporting the pinion 47 48, the first stopper 51 formed below the pinion 47 and converting the rotational motion of the pinion 47 into a linear motion is not directly formed and coupled to the main body, but first the gearbox ( 56) integrally assembled. In addition, the gearbox 56 is coupled to the main body 2 by a gearbox fastening member 57.

 As described above, each component is not individually coupled to the main body 2, but is assembled to the gearbox 56 in advance and coupled to the main body 2, thereby facilitating manufacturing and coupling between the components. It can increase the reliability.

FIG. 6 is an enlarged perspective view showing in detail the mutual relationship between the engaging portion 33 and the first stopper 51 and the second stopper 52 in FIG. 2.

As described above with reference to FIG. 2, the earphone rotary shaft 31, the earphone-side elastic member 32, and the locking part 33 are formed at the lower end of the spacer 7. In addition, the earphone-side elastic member 32 provides an elastic force to rotate the earphone 6 in the pulled out state.

In addition, the first stopper 51 or the second stopper 52 is caught by the engaging portion 33 formed in the earphone 6, so that the earphone 6 is withdrawn when the earphone 6 is in a retracted state. It is a supportive role.

Meanwhile, as described above with reference to FIG. 2, the first stopper 51 interacts with the cover part 21, the cam 41, the cam rotation shaft 42, the rack 46, and the pinion 47. .

In detail, when the cover part 21 is opened and closed, the cam rotation shaft 42 and the cam 41 coupled to the cover part 21 are rotated by the rotation of the cover part 21. When the cam 41 rotates, the rack 46 coupled to the cam 41 linearly moves back and forth. Then, when the rack 46 is in a linear motion, the pinion 47 converts the linear motion back into a rotational motion. Finally, when the pinion 47 rotates, the first stopper 51 formed in the shape of a rack engaged with the pinion 47 straightens the rotational movement of the pinion 47 again. The motion is converted into a linear motion in the front and rear directions.

As a result, the rotational movement of the cover portion 21 is converted / transmitted into the linear movement of the first stopper 51, and the bearing force is applied to the locking portion 33 by the linear movement of the first stopper 51. The provided or provided supporting force is removed to control the withdrawal or withdrawal of the earphone 6.

In other words, when the cover part 21 is opened, the first stopper 51 retreats (in the opposite direction to the earphone). Therefore, the supporting force provided to the locking portion 33 is removed, so that the earphone 6 is rotated in the pulled out state. On the other hand, when the cover part 21 is closed, the first stopper 51 is advanced (in the direction of the earphone), and thus the supporting force is provided to the locking part 33 again, so that the earphone 6 is in the withdrawn state. It prevents rotation.

Fig. 7 is an enlarged view of part III of Fig. 6, (a) is a plan view of part III, Fig. 7 (b) is a side view of part III, and Fig. 7 (c) is a front view of part III. .

Referring to FIG. 7A, chambers 51a and 52a are formed at corner portions where the first stopper 51 and the second stopper 52 meet each other. When the second stopper 52 supports the engaging portion 33 by the respective chambers 51a and 52a, the first stopper 51 moves forward to move the second stopper 52 forward. Push out, it can take the role of supporting the locking portion 33.

Referring to FIG. 7B, the first stopper 51 and the second stopper 52 each form a level of a certain level. As described above, the first stopper 51 and the second stopper 52 form a structure in which the height difference is a certain degree, so that the first stopper 51 completely pushes out the second stopper 52 and its role. Until it replaces, the engaging portion 33 can be maintained without being pulled out position.

Referring to FIG. 7C, a chamber 33a is formed at a lower end of the locking part 33 in contact with an upper end of the second stopper 52. When the earphone 6 is retracted by the chamber 33a, the second stopper 52 protrudes through the protruding second stopper 52 and is rotated to the lower end of the second stopper 52, thereby allowing the second stopper 52 to enter the second stopper 52. May be supported and not withdrawn again.

That is, the chambers 33a, 51a and 52a formed in the respective components serve as guides for moving to the positions that each component should occupy. The relationship between each of the components may be more clear with reference to the operation or operation of the present invention described later.

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

First, the state in which the sound device 1 is waiting for use will be mainly described.

In the state where the acoustic device 1 is in use, the earphone 6 is accommodated in the main body 2 and is supported by the main body 2. In addition, the part where the earphone 6 protrudes to the outside of the main body 2 is protected by the cover part 21. That is, since the main body 2 and the cover 21 are coupled while the earphone 6 is retracted while the acoustic device 1 is in use, the earphone 6 is completely exposed to the outside. It doesn't work. Due to such a stable structure, it is possible to obtain the advantages that the portable device 1 is easy to carry, easy to store, to prevent breakage, to improve operation stability, and to have a simple and beautiful appearance.

Of course, the cover portion 21 is axially coupled to the main body 2, the cover portion 21 is shown to be opened and closed by the rotational movement, but this is only one embodiment. That is, the cover part is completely detachable from the main body 2, and may be provided in various aspects, such as a cover part coupled to the main body 2 and opened and closed by linear movement.

On the other hand, the acoustic device 1 is a general state that the user continues to use, like a mobile phone, it is preferable to be placed in a position that can be reached by the user at any time. To this end, a clip (not shown) may be formed on any one side of the main body 2 of the acoustic apparatus 1. The clip extends from one end of the main body 2 to the other end, and the clip can be deformed to some extent by itself. Therefore, the user can easily mount the acoustic device 1 using the clip at the corner of the shirt or the like of the shirt. When the sound device 1 is to be used, such as a telephone call to the mobile phone, the sound device 1 can be easily taken out and used.

The clip is to improve the usability when the sound device (1) of the present invention is provided in a rod or cylindrical shape, when the sound device (1) is used in the form of a ballpoint pen, etc. The usability can be further improved.

Hereinafter, the process in which the acoustic device 1 is used will be described in more detail.

The opening and closing of the cover portion 21 and the withdrawal operation of the earphone 6 can be clearly understood by FIGS. 8 to 10. FIG. 8 is a cross-sectional view and an enlarged perspective view of a standby state of the sound device 1, that is, a state in which the cover 21 is closed and the earphone 6 is retracted. 10 is a cross-sectional view and an enlarged perspective view of the state in which the cover part 21 is opened and the earphone 6 is in the withdrawal operation, and FIG. 10 is a cross-sectional view and an enlarged perspective view of the state in which the earphone 6 is completely drawn out and the cover part 21 is closed. (The arrows in the enlarged perspective view indicate the direction in which each component moves.)

When a call comes to a mobile phone or the like, and the user wants to use the acoustic device 1, the cover 21 is opened, the earphone 6 is pulled out, and the cover 21 is closed again.

In more detail, the cover 21 is closed and the earphone 6 is retracted in a standby state in which the sound device 1 is not used. At this time, the locking portion 33 formed at the lower end of the earphone 6 is supported by the first stopper 51 so that its fixed position is maintained, and the locking portion 33 and the first stopper 51 are supported. By the interaction of the) the earphone 6 is not drawn out. At this time, the second stopper 52 is pushed toward the earphone rotation shaft 31 by the second stopper side elastic member 53, but is in contact with the side surface of the locking portion 33, It is not intervened in the position fixing action by the interaction of the locking portion 33 and the first stopper 51. (Fig. 8)
