[0010] The inventors have provided the accompanying drawings and the following description to enable those skilled in the art to fully understand the present disclosure, and do not intend for them to limit the subject matter described in the claims.

[0011] (Embodiment) [1. Speaker device configuration] The configuration of a speaker device 2 according to an embodiment will be described with reference to Figs. 1 to 4. Fig. 1 is a perspective view showing the appearance of the speaker device 2 according to the embodiment. Fig. 2 is a schematic cross-sectional view of the speaker device 2 according to the embodiment taken along line II-II in Fig. 1. Fig. 3 is a schematic cross-sectional view of the speaker device 2 according to the embodiment in a state before the receiving member 14 is attached to the through-hole 30. Fig. 4 is a schematic cross-sectional view of the speaker device 2 according to the embodiment taken along line IV-IV in Fig. 2.

[0012] 1 to 4, the left-right direction of the speaker device 2 is the X-axis direction, the front-rear direction of the speaker device 2 is the Y-axis direction, and the up-down direction of the speaker device 2 is the Z-axis direction. The positive side of the X-axis is the "right," the negative side of the X-axis is the "left," the positive side of the Y-axis is the "rear," the negative side of the Y-axis is the "front," the positive side of the Z-axis is the "up," and the negative side of the Z-axis is the "down."

[0013] As shown in FIGS. 1 to 4, the speaker device 2 includes a cabinet 4, a speaker unit 6, a support member 8, and a plurality of insulators 10.

[0014] The cabinet 4 has a cabinet body 12 and a plurality of receiving members 14 .

[0015] The cabinet body 12 is a box-shaped (hollow rectangular parallelepiped) housing for accommodating the speaker unit 6, and is made of, for example, resin or wood. The cabinet body 12 has a front panel 16, a back panel 18, a right side panel 20, a left side panel 22, a top panel 24, and a bottom panel 26.

[0016] The front panel 16 and the back panel 18 are arranged to face each other in the front-to-back direction (Y-axis direction). The front panel 16 forms the front surface of the cabinet main body 12. The back panel 18 forms the back surface (the surface opposite to the front surface) of the cabinet main body 12. An opening 28, for example, having a circular shape, is formed in approximately the center of the front panel 16 to expose a diaphragm 42 (described later) of the speaker unit 6 to the outside.

[0017] The right side plate 20 and the left side plate 22 are arranged to face each other in the left-right direction (X-axis direction). The right side plate 20 forms the right side surface of the cabinet main body 12. The left side plate 22 forms the left side surface of the cabinet main body 12 (the surface opposite to the right side surface).

[0018] The top plate 24 and the bottom plate 26 are disposed so as to face each other in the vertical direction (Z-axis direction). The top plate 24 forms the top surface of the cabinet main body 12. The bottom plate 26 forms the bottom surface of the cabinet main body 12 (the surface opposite to the top surface).

[0019] A plurality of through holes 30, each having a circular shape, are formed on each side surface of the cabinet body 12 except for the front plate 16 and the back plate 18. Specifically, a plurality of through holes 30 are formed at intervals along the up-down direction on each of the right side plate 20 and the left side plate 22. A plurality of through holes 30 are also formed at intervals along the left-right direction on each of the top plate 24 and the bottom plate 26. That is, the plurality of through holes 30 are arranged at intervals in an annular shape in a plane parallel to the XZ plane. A female screw portion 32 having a thread groove is formed on the inner circumferential surface of each of the plurality of through holes 30. The female screw portion 32 is formed, for example, by an annular embedded nut made of metal.

[0020] The plurality of receiving members 14 are respectively disposed in the plurality of through holes 30 of the cabinet body 12. Each of the plurality of receiving members 14 is formed, for example, in a substantially cylindrical shape and is made of metal such as brass or aluminum. One end face of each of the plurality of receiving members 14 (the end face facing the inside of the cabinet body 12) is formed with a conically recessed concave surface 34. Furthermore, a male screw portion 36 having a screw groove is formed on the outer circumferential surface of each of the plurality of receiving members 14.

[0021] As shown in FIG. 3 , the receiving member 14 is attached to the through hole 30 by screwing the male thread portion 36 of the receiving member 14 into the female thread portion 32 of the through hole 30 from the outside of the cabinet body 12 (i.e., by rotating the male thread portion 36 in the tightening direction relative to the female thread portion 32). The tightening direction is the direction in which the male thread portion 36 moves while rotating within the female thread portion 32 toward the inside of the cabinet body 12. At this time, as shown in FIG. 1 , the receiving member 14 can be seen through the through hole 30 from the outside of the cabinet body 12. After the receiving member 14 is attached to the through hole 30, the receiving member 14 may be completely fixed to the through hole 30 with an adhesive or the like to prevent the receiving member 14 from loosening (i.e., to prevent the male thread portion 36 from rotating relative to the female thread portion 32 in the direction opposite to the tightening direction).

[0022] The speaker unit 6 is an acoustic unit for outputting sound. At least a portion of the speaker unit 6 is disposed inside the cabinet body 12 so as to close the opening 28 of the cabinet body 12. The speaker unit 6 has a field magnet portion 38, a frame 40, a diaphragm 42, an edge 68, a voice coil bobbin 44, a damper 46, and a voice coil 48. Note that a portion of the speaker unit 6 (for example, the edge 68, etc.) may be disposed outside the cabinet body 12, or the entire speaker unit 6 may be disposed inside the cabinet body 12.

[0023] The field magnet section is disposed behind the diaphragm (on the positive side of the Y-axis), and includes a base plate 50, a top plate 52, and a magnet .

[0024] The base plate 50 is made of, for example, iron, and has a cylindrical portion 56 and a flange portion 58 that protrudes radially outward from the rear end (the end on the positive side of the Y axis) of the cylindrical portion 56. The flange portion 58 of the base plate 50 supports the magnet 54 from behind.

[0025] The top plate 52 is made of, for example, iron and has a disk shape, and is disposed so as to cover the magnet 54 from the front. A circular opening 60 is formed in the approximate center of the top plate 52.

[0026] The magnet 54 is formed in a cylindrical shape and is supported between a flange portion 58 of the base plate 50 and the top plate 52. A circular opening 62 is formed in the center of the magnet 54. The opening 62 of the magnet 54 is in communication with the opening 60 of the top plate 52.

[0027] The cylindrical portion 56 of the base plate 50 is inserted through the opening 62 of the magnet 54 and the opening 60 of the top plate 52. A magnetic gap 64 is formed between the cylindrical portion 56 of the base plate 50 and the inner circumferential surface of the opening 60 of the top plate 52.

[0028] The frame 40 is for holding the outer periphery of the diaphragm 42 on the periphery of the opening 28 of the cabinet main body 12, and is formed of, for example, resin or metal. The frame 40 has a cone-like (approximately truncated cone) shape that expands in diameter from the rear end (the end on the positive side of the Y axis) to the front end (the end on the negative side of the Y axis) around the central axis 66 of the speaker unit 6. The front end of the frame 40 is disposed on the periphery of the opening 28 of the cabinet main body 12. The rear end of the frame 40 is fixed to the top plate 52 of the field magnet part 38.

[0029] The diaphragm 42 has a cone-like shape that widens in diameter from the rear end (the end on the positive side of the Y-axis) to the front end (the end on the negative side of the Y-axis) around the central axis 66 of the speaker unit 6. The front end of the diaphragm 42 is supported by the front end of the frame 40 via an edge 68 so that it can vibrate. A hemispherical center cap 70 is attached to the open radial center of the diaphragm 42. The shape of the center cap 70 is not limited to a hemispherical shape and may be other shapes. Furthermore, another member may be used in place of the center cap 70.

[0030] The voice coil bobbin 44 is connected to the rear end of the diaphragm 42 and extends rearward from the rear end of the diaphragm 42 in a cylindrical shape.

[0031] The damper 46 connects the outer peripheral surface of the voice coil bobbin 44 to the inner surface of the frame 40. As a result, the voice coil bobbin 44 is supported by the inner surface of the frame 40 via the damper 46 so as to be able to vibrate.

[0032] The voice coil 48 is wound around the outer peripheral surface of the voice coil bobbin 44 and is positioned in a magnetic gap 64 formed between the cylindrical portion 56 of the base plate 50 and the inner peripheral surface of the opening 60 of the top plate 52.

[0033] A magnetic field is generated in the magnetic gap 64 in which the voice coil 48 is disposed by the magnetic force from the magnet 54. When a current flows through the voice coil 48, the voice coil 48 receives a force from the magnetic field in the magnetic gap 64 and vibrates. When the vibration of the voice coil 48 is transmitted to the voice coil bobbin 44, the diaphragm 42 connected to the voice coil bobbin 44 vibrates in the front-to-rear direction (the direction indicated by the arrow 72 in FIG. 2), and sound waves are generated from the diaphragm 42.

[0034] The support member 8 is a member for supporting the speaker unit 6, and is formed of, for example, a rectangular plate member. The support member 8 is formed of, for example, metal, resin, or wood. The support member 8 is disposed inside the cabinet main body 12. Specifically, the support member 8 is disposed so that its thickness direction (Y-axis direction) substantially coincides with the vibration direction of the diaphragm 42 (the direction indicated by arrow 72 in FIG. 2). As shown in FIG. 2, a front surface 74 of the support member 8 is disposed so as to face the front plate 16 of the cabinet main body 12. A back surface 76 of the support member 8 is disposed so as to face the back plate 18 of the cabinet main body 12.

[0035] As shown in FIG. 4 , a right side 78 of the outer periphery of the support member 8 is arranged to face the plurality of through holes 30 formed in the right side plate 20 of the cabinet body 12. A left side 80 of the outer periphery of the support member 8 is arranged to face the plurality of through holes 30 formed in the left side plate 22 of the cabinet body 12. An upper side 82 of the outer periphery of the support member 8 is arranged to face the plurality of through holes 30 formed in the top plate 24 of the cabinet body 12. A lower side 84 of the outer periphery of the support member 8 is arranged to face the plurality of through holes 30 formed in the bottom plate 26 of the cabinet body 12. In this embodiment, the support member 8 is not in direct contact with the cabinet body 12, but is supported by the cabinet body 12 only via a plurality of insulators 10 and a plurality of receiving members 14, which will be described later.

[0036] 2 and 4, a circular opening 86 is formed in the approximate center of the support member 8. The magnet 54 of the field magnet unit 38 is inserted through the opening 86 of the support member 8. For convenience of explanation, the field magnet unit 38 and the screw holes through which screws 88 (described later) are inserted are not shown in FIG. 4. In the present embodiment, only one opening 86 is provided in the approximate center of the support member 8, but this is not limiting, and the number and position of the openings 86 may be arbitrary.

[0037] Furthermore, the front surface 74 of the support member 8 functions as a support surface that supports the field magnet portion 38 of the speaker unit 6. The top plate 52 of the field magnet portion 38 is supported on the support surface of the support member 8, and the two are attached with a plurality of screws 88. Note that the method of fixing the support member 8 and the top plate 52 shown in FIG. 2 is one example, and other fixing methods may be used. An imaginary plane 90 (shown by a dashed line in FIG. 2) that includes the support surface includes the center of gravity 92 of the speaker unit 6. Because the weight of the field magnet portion 38 is greater than the weight of the diaphragm 42, the center of gravity 92 of the speaker unit 6 is located in a position that is biased closer to the field magnet portion 38 than the diaphragm 42 in the front-to-rear direction.

[0038] In this embodiment, the plane 90 includes the position 92 of the center of gravity of the speaker unit 6, but the plane 90 does not necessarily have to include the position 92 of the center of gravity of the speaker unit 6. Also, in this embodiment, the field magnet portion 38 of the speaker unit 6 is supported by the support member 8, but this is not limited to this, and a member other than the field magnet portion 38 of the speaker unit 6 (for example, the frame 40, or another member provided on the speaker unit 6 for mounting on the support member 8) may be supported by the support member 8. Alternatively, the members constituting the speaker unit 6 (for example, the top plate 52, the base plate 50, the frame 40, etc.) may be formed integrally with the support member 8, or the speaker unit 6 may be supported by the support member 8 via a separate member.

[0039] Each of the multiple insulators 10 is formed, for example, in a conical shape and is made of metal such as brass or aluminum. Each of the multiple insulators 10 is arranged on a part of the outer periphery of the support member 8 (i.e., on an end of the support member 8). That is, the multiple insulators 10 are arranged at intervals along the circumferential direction of the outer periphery of the support member 8 (i.e., at intervals on the end of the support member 8). Although not shown, each of the multiple insulators 10 has a male thread portion, and the male thread portion is screwed into a female thread portion formed on the outer periphery of the support member 8, thereby fixing the multiple insulators 10 to the outer periphery of the support member 8. Note that the method of fixing the multiple insulators 10 to the outer periphery of the support member 8 is not limited to this, and the multiple insulators 10 may also be fixed to the outer periphery of the support member 8 with an adhesive or the like.

[0040] Each of the multiple insulators 10 protrudes in a conical shape from part of the outer periphery of the support member 8 in a direction approximately perpendicular to the vibration direction of the diaphragm 42, and its top is in point contact with the bottom of the concave surface 34 of the receiving member 14.

[0041] 4, each of the multiple insulators 10 arranged on a portion of the right side 78 of the support member 8 protrudes in a conical shape in a direction (positive side of the X-axis) substantially perpendicular to the vibration direction of the diaphragm 42. The tops of the multiple insulators 10 are in point contact with the bottoms of the respective concave surfaces 34 of the multiple receiving members 14 arranged in the respective through holes 30 of the right side plate 20 of the cabinet body 12. At this time, by screwing the respective male thread portions 36 of the multiple receiving members 14 into the respective female thread portions 32 of the respective through holes 30, the respective concave surfaces 34 of the multiple receiving members 14 press the respective multiple insulators 10 leftward (negative side of the X-axis).

[0042] Furthermore, each of the multiple insulators 10 arranged on a portion of the left side 80 of the support member 8 protrudes in a conical shape in a direction (the negative side of the X-axis) substantially perpendicular to the vibration direction of the diaphragm 42. The tops of the multiple insulators 10 are in point contact with the bottoms of the concave surfaces 34 of the multiple receiving members 14 arranged in the multiple through holes 30 of the left side panel 22 of the cabinet body 12. At this time, by screwing the male threaded portions 36 of the multiple receiving members 14 into the female threaded portions 32 of the multiple through holes 30, the concave surfaces 34 of the multiple receiving members 14 press the multiple insulators 10 to the right (the positive side of the X-axis).

[0043] As a result, the right side 78 of the support member 8 is pressed from the right by the plurality of receiving members 14 arranged in the plurality of through holes 30 of the right side plate 20 of the cabinet body 12. Also, the left side 80 of the support member 8 is pressed from the left by the plurality of receiving members 14 arranged in the plurality of through holes 30 of the left side plate 22 of the cabinet body 12. In other words, the support member 8 is supported (clamped) by being pressed from the left and right by the plurality of receiving members 14.

[0044] Furthermore, each of the multiple insulators 10 arranged on a portion of the upper side 82 of the support member 8 protrudes in a conical shape in a direction (positive side of the Z axis) substantially perpendicular to the vibration direction of the diaphragm 42. The tops of the multiple insulators 10 are in point contact with the bottoms of the respective concave surfaces 34 of the multiple receiving members 14 arranged in the respective through holes 30 of the top plate 24 of the cabinet body 12. At this time, by screwing the respective male thread portions 36 of the multiple receiving members 14 into the respective female thread portions 32 of the respective through holes 30, the respective concave surfaces 34 of the multiple receiving members 14 press the respective multiple insulators 10 downward (negative side of the Z axis).

[0045] Furthermore, each of the multiple insulators 10 arranged on a portion of the lower side 84 of the support member 8 protrudes in a conical shape in a direction (negative side of the Z axis) substantially perpendicular to the vibration direction of the diaphragm 42. The tops of the multiple insulators 10 are in point contact with the bottoms of the respective concave surfaces 34 of the multiple receiving members 14 arranged in the respective through holes 30 of the bottom plate 26 of the cabinet body 12. At this time, by screwing the respective male thread portions 36 of the multiple receiving members 14 into the respective female thread portions 32 of the respective through holes 30, the respective concave surfaces 34 of the multiple receiving members 14 press the respective multiple insulators 10 upward (positive side of the Z axis).

[0046] As a result, the upper edge 82 of the support member 8 is pressed from above by the plurality of receiving members 14 arranged in the plurality of through holes 30 of the top plate 24 of the cabinet body 12. Also, the lower edge 84 of the support member 8 is pressed from below by the plurality of receiving members 14 arranged in the plurality of through holes 30 of the bottom plate 26 of the cabinet body 12. In other words, the support member 8 is supported (sandwiched) by being pressed from above and below by the plurality of receiving members 14.

[0047] When assembling the speaker device 2, with the support member 8 placed inside the cabinet main body 12, the male threaded portions 36 of the plurality of receiving members 14 are screwed into the female threaded portions 32 of the plurality of through holes 30 from the outside of the cabinet main body 12, and the tops of the plurality of insulators 10 are brought into contact with the concave surfaces 34 of the plurality of receiving members 14. In this way, the plurality of receiving members 14 are attached to the plurality of through holes 30, respectively, and the support member 8 is supported by the cabinet main body 12 via the plurality of insulators 10.

[0048] In this embodiment, each of the multiple insulators 10 is configured to protrude from a portion of the outer periphery of the support member 8 in a direction approximately perpendicular to the vibration direction of the diaphragm 42, but this is not limited to this and the insulators 10 may protrude in any direction from a portion of the outer periphery of the support member 8.

[0049] [2.Effects] In this embodiment, as described above, the support member 8 that supports the speaker unit 6 is supported on the cabinet main body 12 via a plurality of insulators 10 and a plurality of receiving members 14. This makes it possible to reduce the contact area between the insulators 10 and the receiving members 14, so that when vibrations occur in the speaker unit 6, the vibrations of the speaker unit 6 can be prevented from being transmitted to the cabinet 4 via the support member 8. As a result, the sound quality of the speaker device 2 can be improved.

[0050] Furthermore, in this embodiment, as described above, the imaginary plane 90 including the support surface of the support member 8 includes the center of gravity position 92 of the speaker unit 6. This makes it possible to maintain a good weight balance of the speaker unit 6, and to suppress transmission of vibrations of the speaker unit 6 to the cabinet 4 when outputting sound.

[0067] (Other embodiments) As described above, the embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which appropriate modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in the above embodiments to create new embodiments.

[0068] Therefore, other embodiments will be exemplified below.

[0069] In the above embodiment, the speaker device 2 is described as having a plurality of receiving members 14, but the present invention is not limited to this, and the speaker device 2 may have only one receiving member 14.

[0070] Furthermore, in the above embodiment, the support member 8 is supported on the cabinet main body 12 only by the insulator 10 and the receiving member 14, but this is not limiting and may be combined with other fixing methods such as adhesive bonding or screw fastening. That is, a part of the outer periphery of the support member 8 may be supported on the cabinet main body 12 by the insulator 10 and the receiving member 14, and another part of the outer periphery of the support member 8 may be fixed to the cabinet main body 12 by another fixing method.

[0071] Furthermore, in the above embodiment, the support member 8 and the plurality of insulators 10 are configured as separate bodies, but this is not limitative, and the support member 8 and the plurality of insulators 10 may be configured as an integral body.

[0072] In addition, in the above embodiment, the insulator 10 is formed in a conical shape, but this is not limited thereto and it may be formed in a pyramidal shape, such as a triangular pyramid or a square pyramid. Similarly, in the above embodiment, the concave surface 34 of the receiving member 14 is formed in a conical shape, but this is not limited thereto and it may be formed in a pyramidal shape, such as a triangular pyramid or a square pyramid.

[0073] In the above embodiment, the insulator 10 is formed as a cone-shaped protrusion, and the receiving member 14 is formed as a cone-shaped concave surface. However, the insulator 10 may be formed as a cone-shaped concave surface, and the receiving member 14 may be formed as a cone-shaped protrusion. In this case, the insulator 10 is disposed at the end of the support member 8 and has a cone-shaped concave surface (for example, a concave surface formed to be recessed into the end surface of the support member 8). The receiving member 14 protrudes in a cone shape, and its apex is in point contact with the concave surface of the insulator 10. In this case, the receiving member 14 may protrude in a direction substantially perpendicular to the vibration direction of the diaphragm 42, for example.

[0074] In the above embodiment, the insulator 10 is in point contact with the receiving member 14, but this is not limitative, and the insulator 10 may be in line contact or surface contact with the receiving member 14.
