It has a second space part 35. The second space part 35 serves as a buffer to alleviate the pain in the ear when the terminal is inserted, and naturally outputs the sound output delivered to the ear by concentrating the flow of sound uttered by the speaker body 23 in the space. To improve. In this case, the first hole 34 serves to transfer the voice sound concentrated in the second space part 35 into the ear.

In addition, a plurality of second holes 36 are formed in the first protruding ring 33 to free the flow of sound uttered behind the speaker unit 21. In addition, the voiced sound inlets of the second holes 36 are interconnected by grooves 37 so that when one of the second holes 36 is blocked by the toothed portion 13, the sound that is spoken backward is heard. It can be easily attracted to another hole along the groove 37.

Hereinafter, the method of assembling the acoustic receiving terminal having a shock absorbing cover according to an embodiment of the present invention and the operation after wearing it in the ear will be described in detail.

First, the speaker main body 23 of the speaker unit 21 is inserted into the first space 32 of the shock absorbing cover 31 to be accommodated. At this time, the first protrusion ring 33 is caught by the rear of the body of the speaker body (23). On the other hand, the front of the speaker body 23 is accommodated to face the front of the second space portion 35, the front of the speaker body 23 and the second space portion 35 is the first protrusion ring 33 It is partitioned from each other by a second protruding ring 38 of similar shape to. That is, the speaker body 23 is wrapped by the first protrusion ring 33 and the second protrusion ring 38 to be tightly received in the first space part 32.

Thereafter, the speaker unit 21 covered with the shock absorbing cover 31 is coupled to the coupling part 15 of the terminal body 11. That is, the rear of the speaker body 23 corresponding to the coupling portion 15 is inserted into the coupling portion. Prior to this, an adhesive capable of instant bonding to the coupling part 15 is applied. As such, when the speaker unit 21 covered with the shock absorbing cover 31 is coupled to the coupling part 15 of the terminal body 11, the tooth part 13 strongly bites the first protrusion ring 33. At that moment, the adhesive is strongly bonded to the coupling part 15 and the rear of the speaker body 23 so that the body of the shock absorbing cover 31 is firmly supported by the terminal body 11 while being bitten by the tooth part 13. .

Therefore, when the terminal combined with the shock absorbing cover 31 is inserted into the wheel, the second space part 35 is stably grounded inside the wheel. At this time, the pressure pressurizing the terminal by the wearer's movement is absorbed and dissipated by the soft cushion cover 31 of a predetermined thickness and by the buffering action of the buffer space of the second space part 35, thereby extinguishing the wheel itself and the wheel. Rubbing of the medial ear canal does not directly irritate or pain the ear. That is, the close contact by the second space part 35 is very soft to the touch, excellent adhesion to promote pain relief. In addition, since the second space part 35 is in close contact with the inside of the auricle, it is possible to effectively block external noise so that the output of sound is improved and does not disturb others. In addition, since the speaker unit 21 is instantaneously bonded to the coupling part 15 while the tooth part 13 strongly presses the first protruding ring 33, the shock absorbing cover 31 is inserted into or removed from the wheel. 11) to prevent the departure. In addition, since the sound uttered forward from the speaker body 23 can be naturally concentrated in the second space part 35, the sound transmitted to the ear is improved by the resonance space of the second space part 35. do.

In addition, since a plurality of second holes 36 are formed in the first protruding ring 33, the sound uttered behind the speaker body 23, that is, the noise is naturally caught and emitted to the outside, resulting in high quality sound. You can listen in comfort. When the tooth 13 bites the first protruding ring 33, the tooth 13 may block the second hole 36. At this time, since the voiced sound inlets of the second holes 36 are connected to each other by the grooves 37, the sound flowing into the hole blocked by the teeth of the teeth 13 passes through the grooves 37 and the teeth 13 ) Will flow into the other unblocked hole.

In addition to these actions, unlike the conventional method of inducing a high cost due to the complexity of the process because the assembly process of the terminal is simple, a low cost productivity process is possible to secure a competitive advantage.

On the contrary, as shown in FIG. 3, the buffer cover 31 extends in the first space part 32 to have a predetermined space, and the front surface in which the plurality of first holes 34 are formed is recessed and annular. It may also have a second space portion 35 formed. Therefore, the annular portion of the shock absorbing cover 31 is completely adhered to the inner ear, thereby further improving the buffering property and not irritating the skin of the inner ear. Then, the sound emitted from the speaker main body 23 is concentrated in the recessed space, thereby high output into the ear.

However, the second space portion 45 of the buffer cover 41 extends to the first space portion 32 and is formed in an annular shape in which one side is open.

In addition, as shown in FIG. 6, the second space part 45 may have a tooth groove 46 formed at an end portion of the annular inner circumferential surface opposite to the speaker body 23. As illustrated in FIG. 7, a plurality of third holes 47 having a predetermined shape, for example, a quadrangular shape, may be further formed on the inner circumferential surface of the second space part 45. Alternatively, as shown in FIG. 8, a plurality of third holes 48 having a circular shape may be formed on the inner circumferential surface of the second space part 45. Here, the shape of the third holes 47 and 48 is not limited thereto, and the action of the tooth grooves 46 and the third holes 47 and 48 may be a part of the sound generated from the speaker body 23. This flows into the open annular second space portion 45 and concentrates the central portion of the speaker body 23.

As a result, the annular second space portion 45 is rounded to ground the inside of the auricle as a whole, thereby providing cushioning. That is, the annular second space portion 45 is smoothly grounded to the pinching portion of the ear canal so as not to irritate the ear. In addition, it is excellent in sealing property so that the sound of the speaker body 23 flows directly into the ear. In addition, by concentrating a part of the sound flowing out of the speaker body 23 to the center of the speaker body 23 through the tooth groove 46 and the third holes 47 and 48, the wearer is always in a comfortable state and of good quality. You can listen to the sound.

(13) is composed of a soft buffer cover 51 is fixed to prevent the pain caused by the ear. However, the second space portion 55 of the shock absorbing cover 51 is a protrusion type having a space extending to the first space portion 32 and gradually narrowed toward the front side, for example, is formed in a trumpet shape, The formation of the plurality of fourth holes 49 is characteristically different from that of the other embodiments described above.

As a result, the protruding second space portion 55 allows the inside of the auricle to be grounded as a whole and deeply, and has a buffering effect by expanding the buffer space more widely. That is, the second space portion 55 of the protruding type is gently grounded to the pinching portion of the ear canal so as not to irritate the ear by closely adhering inwardly. In addition, the sound emitted from the speaker body 23 is concentrated in a large space of the second space part 55 so as to be transmitted to the ear through the fourth hole 49 so that the wearer can always listen to high quality sound in a comfortable state. Will be.

As described above, the acoustic receiving terminal having a shock absorbing cover according to the present invention prevents the shock absorbing cover from being detached from the terminal body due to friction when the inner and outer wheels are inserted and removed due to the firm fixing of the shock absorbing cover. There is a first advantage to that.

In addition, there is a second advantage in that not only to prevent the pain caused by the inner ear wheel by the space portion in close contact with the ear, but also improve the output of the sound.
