Unless otherwise stated, the description of any one embodiment may be applied to other embodiments, and a detailed description thereof will be omitted in the overlapping scope.

FIG. 1 is a perspective view of a speaker module according to an embodiment of the present invention. FIG. 2 (a) is a cross-sectional view of a speaker module according to one embodiment, and FIG. 2 (b) is an exploded sectional view of a speaker module according to an embodiment.

Referring to FIGS. 1 and 2B, the speaker module 1 according to an embodiment can transmit a sound by contacting a user. The speaker module 1 may include a case 11, a speaker 12, a contact pad 13, a suspension 14, a vibration transmitting plate 15 and a buffer member 16.

The case 11 may include a space for accommodating other components therein. The case 11 may include a protrusion 111, a protrusion 112 and a protective member 113, which are openings 114 (see FIG. 2B), stepped portions 115 (see FIG.

The opening 114 can be opened toward the contact portion of the user. The opening 114 may be provided with a vibration transmitting plate 15 connecting the speaker 12 and the contact pad 13. [ The opening 114 may be formed, for example, in a central portion of the stepped portion 115.

The stepped portion 115 may be recessed toward the speaker 12. The contact pad 13 is disposed on the stepped portion 115, and the opening 114 can be covered. For example, the shape of the rim of the stepped portion 115 coincides with the shape of the rim of the contact pad 13, and the contact pad 13 can be inserted and fitted to the rim of the stepped portion 115. As a result, the case 11 and the contact pad 13 can form a closed space.

Since the speaker 12 disposed inside the case 11 is an electronic device, it may be damaged if exposed to the outside, especially water. Therefore, the waste space formed by this method can prevent contact with the outside and improve the durability of the speaker module 1. The case 11 and the contact pad 13 can form a single curved surface when the contact pad 13 is inserted and fitted to the stepped portion 115.

The suspension 14 supports the speaker 12 disposed inside the case 11 in a state of being spaced apart from the inner wall of the case 11 to attenuate the vibration generated in the speaker 12, It is possible to reduce the vibration transmitted to the motor. Further, according to the suspension 14, an external shock applied to the speaker 12 can be absorbed. Further, the suspension 14 can tilt the speaker 12 toward the side where the pressure is applied, when the pressure is applied to the contact pad 13. As a result, the contact pad 13 can contact more parts of the two phases, and the vibration of the speaker 12 can be transmitted to the user more efficiently. The material of the suspension 14 may be a metal-based material as well as a nonmetal-based material. For example, the suspension 14 may be made of stainless steel, iron, brass, rubber, silicone, or the like. The suspension 14 may include a first elastic member 141 and a second elastic member 149.

One side of the first elastic member 141 and the other side of the second elastic member 149 may be connected to the speaker 12 and the other side may be connected to the case 11. [ For example, the first elastic member 141 and the second elastic member 149 may be connected to the upper surface of the protrusion 111.

The first elastic member 141 and the second elastic member 149 may be connected to the other side of the speaker 12, respectively. For example, the first elastic member 141 and the second elastic member 149 may be connected to the opposite sides of the speaker 12, respectively. Depending on the position of the pressure applied to the contact pad 13, the speaker 12 may be inclined toward the first elastic member 141 and toward the second elastic member 149 in the opposite direction. In other words, the speaker 12 can be inclined at least in both directions.

The speaker 12 can generate vibration. For example, the speaker 12 can deliver sound to the user in a bone conduction manner. A vibration transmission plate 15 can be connected to one side of the speaker 12 and vibrations generated in the speaker 12 can be transmitted to the contact pad 13 through the vibration transmission plate 15. The speaker 12 may be of various shapes

The speaker 12 may include a contact portion 121 connected to the contact pad 13. The contact portion 121 may have various shapes. For example, the contact portion 131 may have a rectangular shape. As another example, the contact portion 131 may have a circular or elliptical shape.

The contact pad 13 can transmit vibration generated in the speaker 12 to the user in contact with the user. The area of the contact pad 13 may be larger than the area of the contact portion 121 of the speaker 12. [ For example, the contact portion 121 of the speaker 12 can be completely overlapped by the contact pad 13, with respect to a direction perpendicular to the contact portion 121 of the speaker 12. For example, the contact pad 13 may include a groove formed in conformity with the shape of the contact portion 121 of the speaker 12, and the contact portion 12 may be inserted into the groove and connected to the contact pad 13 have. The contact pad 13 is formed of a material that is more flexible than the material of the case 11, so that it can be deformed in accordance with the shape and / or the contact angle of the contact portion of the user. For example, the contact pad 13 may be made of an elastic material such as rubber.

The vibration transmission plate 15 may be disposed between the contact pad 13 and the speaker 12. [ The area of the vibration transmission plate 15 may be larger than the area of the contact portion 121 of the speaker 12 and smaller than the area of the contact pad 13. [ In other words, the areas of the contact portions 121, the vibration transmission plate 15, and the contact pads 13 of the speaker 12 can be sequentially increased. The vibration transmitting plate 15 may be made of a material that is stiffer than the material of the contact pad 13, for example, metal. With such a configuration, it is possible to prevent the contact pad 13 from being excessively deformed, and to transmit the vibration generated by the speaker 12 to the contact pad 13 substantially uniformly.

The buffer member 16 is disposed between the speaker 12 and the case 11 so as to prevent the speaker 12 from falling excessively toward the inner wall of the case 11. [ The buffer member 16 may include a flexible material having elasticity, for example, sponge, styrofoam or rubber. The buffer member 16 can prevent the speaker 12 from directly contacting the inner wall of the case 11 even if an excessive pressure is exerted from the outside through the contact pad 13. [

The height d2 from the inner wall of the case 11 to the upper surface of the contact portion 121 of the speaker 12 may be higher than the height d1 to the upper end of the opening 114. [ In other words, when the speaker module 1 is viewed from the side, the speaker 12 can be exposed to the outside of the opening 114 with the contact pad 13 removed. With such a structure, the speaker 12 can adapt to various directions of pressure better, while reducing the thickness of the contact pads.

3 is a perspective view of a first elastic member according to an embodiment.

Referring to FIG. 3, the first elastic member 141 according to an embodiment may rotate pitch around the first axis A1 or roll about the second axis A2 The speaker 12 connected to the first elastic member 141 can be inclined in various directions. The first elastic member 141 may include a speaker connection portion 142, a case connection portion 143, and a middle portion 144. Since the second elastic member 149 can have the same shape and function as the first elastic member 141, the first elastic member 141 will be described below.

The speaker connection portion 142 may be connected to the speaker 12. For example, the speaker connection portion 142 of the first elastic member 141 may be fixed to the side surface of the speaker 12.

The case connecting portion 143 may be connected to the case 11. [ The case connecting portion 143 can be connected to a columnar protruding portion 111 protruding from the inner wall of the case 11. The projecting portion 111 can separate the first elastic member 141 from the inner wall of the case 11. [ The width of the surface of the protrusion 111 which is in contact with the case connecting portion 143 may be smaller than the width of the case connecting portion 143. The vibration generated in the speaker 12 can be reduced through the first elastic member 141. [ As a result, the vibration generated in the speaker 12 can be transmitted to the contact pad 13 more than the case 11.

The case connecting portion 143 may include a hole through which the protrusion 112 protruding from the protruding portion 111 can pass. The protrusion 112 is inserted into the hole and a protective member 113 may be disposed between the hole and the protrusion 112.

The protective member 113 can be firmly fitted so that the first elastic member 141 does not come off the protruding portion 111 and the protruding portion 112 can be prevented from being damaged. For example, the protective member 113 may be a material having elasticity such as rubber. In this case, the vibration transmitted to the protruding portion 111 can be minimized by absorbing the vibration of the first elastic member 141.

The central portion 144 may connect the speaker connection portion 142 and the case connection portion 143. For example, the case connecting portion 143 and the center portion 144 may be connected to each other in parallel, and the speaker connecting portion 143 and the center portion 144 may be connected to each other at right angles to each other. In other words, the first elastic member 141 can be formed into a "B" shape.

The central portion 144 may include a portion where the width decreases from the speaker connecting portion 142 to the case connecting portion 143. Such a shape can make the roll and pitch rotation of the first elastic member 141 flexible.

The central portion 144 may include at least one groove that is recessed in a direction intersecting the longitudinal direction of the central portion 144. For example, the center portion 144 may include a first groove 145 that is recessed toward the right frame R14 from the left frame L14, and a second groove 145 that is recessed toward the left frame L14 from the right frame R14 And may include a second groove 146. The length of at least one groove of the first groove 145 and the second groove 146 may be at least one-half the width of the central portion 144.

The first groove 145 and the second groove 146 can smooth the roll rotation of the first elastic member 141 around the second axis A2 of the speaker connection portion 142. [ The suspension 14 can be flexibly tilted toward the left edge L14 by the first groove 145 when external pressure is applied to the left edge L14 of the first elastic member 141. [ The first elastic member 141 can be flexibly tilted toward the right rim R14 by the second groove 146 when external pressure is applied to the right rim portion R14 of the first elastic member 141. [

4 is a perspective view of a contact pad according to one embodiment.

Referring to FIG. 4, the contact pad 13 according to one embodiment can transmit vibration in contact with the user's skin. The contact pad 13 may include a portion having a smaller cross-sectional area in a direction away from the speaker 12. According to this configuration, even if the speaker module has various bends in the user's various head parts, the speaker module can be brought into close contact therewith. The contact pad 13 may have a first region 131, a second region 132, and a third region 133.

The central region of the first region 131 may be flat. Both end portions may be bent downward in a direction perpendicular to the longitudinal direction of the first region 131. The second region 132 may extend from one end in the longitudinal direction of the first region 131 and may be curved in a direction in which the speaker 12 is positioned with respect to the center of the first region 131. The third region may extend from the other end in the longitudinal direction of the first region 131 and may be curved in a direction in which the speaker 12 is located with respect to the center of the first region 131. Further, the material of the contact pad 13 may be more flexible than the material of the case 12. Such a shape and material can make the speaker module 1 closely contact with various shapes of the user's head.

5 is a perspective view of a case according to one embodiment.

Referring to FIG. 5, the case 11 according to one embodiment may include an opening 114 and a stepped portion 115.

The stepped portion 115 may be recessed toward the speaker in a shape corresponding to the rim of the first region 131, the second region 132 and the third region 133 of the contact pad 13. [ The contact pad 13 may be disposed on the stepped portion 115. As a result, the first region 131, the second region 132, the third region 133, and the case 11 can form a single curved surface. For example, when a speaker module is applied to a pair of eyeglasses or the like, there may be no apparent difference from a general eyeglass frame.

6 is a perspective view of a speaker module according to an embodiment.

6, the speaker module 2 includes a case 11, a speaker 12, a contact pad 13, a suspension 24, a vibration transmitting plate 15, and a buffer member 16 have. The suspension 24 may include a first elastic member 241 and a second elastic member 249.

The first elastic member 241 includes a speaker connecting portion 242 and a first branch portion 247 and a second branch portion 248 branched from the speaker connecting portion 242 in different directions and connected to the inner wall of the case 11, . ≪ / RTI > For example, the first branch portion 247 and the second branch portion 248 may be connected to the speaker connection portion 242 in a vertical direction.

The first branch portion 247 and the second branch portion 248 may change in position relative to the pressure applied to the contact pad 13. [ For example, when pressure is applied to the first branch 247, the first branch 247 and the second branch 248 are lowered. The first branch 247 is connected to the second branch 247 248, so that the speaker 12 can be tilted toward the first branching portion 247. In this case,

For example, the first branch portion 247 and the second branch portion 248 may form a constant angle and may spread. The first branch portion 247 and the second branch portion 248 may be connected to the protrusions 211 spaced apart from each other. The ends of the first branch portion 247 and the second branch portion 248 may include holes for being connected to the projecting portions 211, respectively. Protrusions protruding from the protrusions 211 are fitted into the holes, and a protection member 213 may be disposed between the protrusions.

Similarly to the first elastic member 241, the second elastic member 249 may include two branched portions. According to such a configuration, since the speaker 12 can be flexibly inclined in the up-and-down direction, the back-and-forth direction, the left-right direction and / or the diagonal direction, the speaker 12 can be complied with by various external forces transmitted through the contact pad 13 have.

7 is a top view of a suspension according to one embodiment.

Referring to FIG. 7, the suspension 34 according to one embodiment may include a first elastic member 341 and a second elastic member 349. The first elastic member 341 may include a speaker connection portion 342, a case connection portion 343, and a middle portion 344.

The central portion 344 may include a plurality of folded features. For example, the center portion 344 may include a shape that is bent a plurality of times in a direction perpendicular to an imaginary line connecting the speaker connection portion 342 and the case connection portion 343. Such a curved shape allows the central portion 344 to be flexible so that the speaker 12 can be flexibly tilted with respect to the two axes A3 and A4 crossing the center of the speaker 12.

8 is a top view of a suspension in accordance with one embodiment.

Referring to FIG. 8, the suspension 44 according to one embodiment may be formed as a single polygonal flat plate. The suspension 44 may include a plurality of elastic members 442 extending from the respective vertexes of the speaker connection portion 441 for supporting the speaker and the speaker connection portion 441 and connected to the case.

For example, as shown in FIG. 8, the speaker connecting portion 441 may have a rectangular shape and four elastic members 442 may be provided. However, the speaker connecting portion 441 may have various polygonal shapes, May be composed of different numbers.

Due to the elastic member 442, the speaker connection portion 441 can vibrate with elasticity in the up-and-down direction and can be inclined in various directions. By adjusting the width, length and / or shape of the elastic member 442, the magnitude of the elastic force in the vertical direction of the suspension 44 can be adjusted.

FIG. 9 is a perspective view of a spectacled wearable device according to an embodiment, and FIG. 10 is a partially cutaway perspective view of a first spectacle frame according to an embodiment.

Referring to FIGS. 9 and 10, the spectacles wearable device 5 according to one embodiment can transmit sound to a user by disposing a bone conduction speaker at a portion contacting the user. The eyeglass wearable device 5 may include a lens frame 59, a first eyeglass leg 51, and a second eyeglass leg 59.

The first spectacles leg 51 includes a speaker 52 that generates vibration, a contact pad 53 that transmits the vibration of the speaker 52 to the user when the user uses the spectacles wearable device 5, A vibration transmission plate 55 for transmitting the vibration of the speaker 52 to the contact pad 53, a suspension 54 for supporting the speaker 52 in a state of being separated from the inner wall of the first eyeglass leg 51, And a buffer member 16 disposed between the speaker 52 and the case 11.

The outer surface of the contact pad 53 can form one curved surface with the outer surface of the first eyeglass leg 51. Because of this shape, the wearable device 5 of the eyeglass type according to one embodiment can have a shape similar to general glasses.

The first eyeglass leg 51 may be rotatably mounted on the lens frame 59, for example. The first eyeglass leg 51 may include a main body portion 517 provided on the lens frame 59, a speaker mounting portion 515 on which the speaker 52 is mounted, and a connector 516.

The speaker mounting portion 515 can be located at the end of the first eyeglass leg 51 and consequently can contact the user's ear when using the spectacles wearable device 5 by the user. The speaker mounting portion 515 may, for example, contact the back portion of the user's temporal bone to deliver sound to the user in a bone conduction manner. As another example, the contact pad 13 may contact the upper portion of the ear of the user's temporal bone and deliver sound to the user in a bone conduction manner. Thus, when the speaker mounting portion 515 contacts the upper or back portion of the user's temporal bone, the vibration generated by the speaker 52 can be transmitted to the user without being disturbed by the hair.

The connector 516 may have greater flexibility than the main body portion 517. For example, the connecting body 516 may be made of a material that is more flexible than the material of the main body portion 517. For example, the main body portion 517 may be made of plastic, and the connection body 516 may be made of rubber. As another example, link 516 may be fabricated to have a flexible nature in a dual injection technique that combines urethane and polycarbonate. For example, the connecting body 516 may be formed in a more flexible shape than the main body portion 517. For example, the maximum cross-sectional area of the connecting body 516 may be smaller than the minimum cross-sectional area of the main body portion 517 with respect to a direction perpendicular to the longitudinal direction of the first eyeglass leg 51.

Due to such a shape and material, the connecting body 516 may be more flexible than the main body portion 517 and the speaker mounting portion 515 which are other portions of the first eyeglass leg 51. As a result, the angle between the main body portion 517 and the speaker mounting portion 515 can be adjusted according to the head size and shape of various users, and the wearer's comfort can be improved.

On the other hand, the maximum cross-sectional area of the connecting body 516 may be smaller than the maximum cross-sectional area of the speaker mounting portion 515 with respect to the direction perpendicular to the longitudinal direction of the first spectacles leg 51. The speaker mounting portion 515, the connecting body 516 and the main body portion 517 function as one large sounding box when the speaker mounting portion 515 and the connecting body 516 have the same cross sectional area, The vibration can be amplified by the resonance tube and propagated to the outside. In contrast, according to the embodiment, since the vibration generated in the speaker 52 can be attenuated or blocked by the connector 516 having a narrow cross-sectional area, the structure is advantageous in that the sound generated in the speaker 52 propagates to the outside Thereby improving the efficiency of transmission to the user in a reflexive manner.

The speaker mounting portion 515, the speaker 52, the contact pad 53, the suspension 54, the vibration transmitting plate 55 and the buffer member 56 may collectively be referred to as a "speaker module ".
