The speaker device 1 can be attached to a member to be attached.
On the other hand, it is possible to simultaneously accommodate the housing portion having a predetermined volume in the restricted space 30S and relatively increase the volume of the housing portion 30 constituting the back cavity. Therefore, the speaker device 1 can be attached to various types of attached members, and good acoustic characteristics can be obtained.

  In the illustrated example, a protective part 41 supported by the frame 40 is provided on the acoustic radiation side of the diaphragm 11. The protection unit 41 is provided to prevent the diaphragm 11 from being touched by other members or the user's hand. In addition, the protective part 41 is provided with an opening through which a sound wave radiated from the diaphragm 11 is passed, and is provided with a bridging part 41 </ b> A that spans the diaphragm 11.

  FIG. 4 is an explanatory view showing in detail the mounting structure of the speaker device according to the embodiment of the present invention. As illustrated, the support portion 31A of the attachment member 31 is formed along an inner protrusion 31A1 that surrounds a part of the housing portion 30 disposed below the flange portion 30C, and a bottom surface portion 30C1 of the flange portion 30C. And an inner side wall portion 31A4 standing in the acoustic radiation direction from the upper surface 31A2 of the inner protruding portion 31A1. Further, the upper surface 31A2 of the inner protruding portion 31A1 is provided as an inner support base 31A3 that supports the bottom surface portion 30C1 of the flange portion 30C. The inner wall portion 31 </ b> A <b> 4 arranges the flange portion 30 </ b> C at a predetermined position with respect to the attachment member 31 in the radial direction of the housing portion 30. If necessary, a predetermined gap may be provided between the inner wall portion 31A4 and the flange portion 30C so that the housing portion 30 can rotate with respect to the attachment member 31.

  The outer peripheral portion of the frame 40 is disposed on the flange portion 30 </ b> C of the housing portion 30 and the support portion 31 </ b> A of the attachment member 31. The flange portion 30C of the housing portion 30 is sandwiched between the support portion 31A of the attachment member 31 and the lower surface of the frame 40, but is supported by being slidable on the upper surface 31A2 (support base 31A2) of the support portion 31A. Yes. In addition, the housing 30 is rotatably attached to the attachment member 31 by fitting the flange 30C into a recess formed by the support base 31A2 and the inner wall 31A.

  In addition, the speaker unit 1 </ b> S includes a frame 40 as a stationary portion that supports the vibrating body 10 on the housing unit 30. The attachment member 31 includes an outer support portion 31B that supports the frame 40 with the support portion 31A that supports the housing portion 30 as an inner support portion (31A). The outer support portion 31B includes an outer support base 31B1 that supports the frame 40, and an outer wall portion 31B2 that is erected from the outer support base 31B1 in the acoustic radiation direction. The frame 40 is supported on the outer support base 31B1 directly or via another member, and the outer wall portion 31B2 places the frame 40 at a predetermined position with respect to the attachment member 31. Note that a predetermined gap may be provided between the outer wall portion 31B2 and the frame 40 as necessary.

  In the illustrated example, a step is formed on the outer support base 31B1 and the upper surface of the flange portion 30C, and the frame 40 and the housing portion 30 are arranged at predetermined positions by this step. Further, a gap is formed between the lower surface of the frame 40 and the outer support base 31B1. By providing this gap, the casing 30 is supported rotatably with respect to the attachment member 31 and the frame 40. The outer peripheral portion of the frame 40 is located inside the outer wall portion 31B2 of the attachment member 31. Further, the outer peripheral portion of the frame 40 is supported in a state in which the frame 40 is fitted in a recess formed by the outer support base 31B1 and the outer wall portion 31B2 of the attachment member 31. Further, the inner peripheral side surface of the frame 40 includes an inclined surface portion that forms a predetermined gap with the inclined surface portion formed in the vicinity of the outer peripheral portion of the housing portion 30. The inclined surface portion formed on the inner peripheral side surface of the frame 40 prevents the housing portion 30 from coming into contact with the frame 40 when the housing portion 30 rotates with respect to the attachment member.

  Further, in the illustrated example, the upper surface of the outer peripheral portion of the housing portion 30 is provided at a position higher than the upper surface of the outer support base 31 </ b> B <b> 1 of the attachment member 31. For this reason, the bottom surface portion of the frame 40 and the outer peripheral portion of the housing portion 30 are in contact with each other, and a predetermined gap is provided between the lower surface of the frame 40 and the upper surface of the mounting member 31. The housing parts 30 are fixed to each other. For example, the upper surface of the outer peripheral portion of the housing 30 may be provided at a position lower than the upper surface of the outer support base 31B1 of the attachment member 31. At this time, the outer peripheral portion of the frame 40 and the outer support base 31B1 of the attachment member 31 are in contact with each other, and a predetermined gap is provided between the lower surface of the frame 40 and the upper surface of the housing portion 30. 31 and the housing | casing part 30 are mutually fixed. After the contact avoiding portion 30 </ b> A of the housing portion 30 is disposed at a predetermined position, the bottom surface portion of the housing portion 30 and the hole portion 23 </ b> B of the yoke 23 may be fixed by the fastening member 33.

  In the illustrated example, the outer side surface of the outer peripheral portion of the housing portion 30 that is disposed to face the attachment member 31 is substantially flat. However, the present invention is not limited to this. For example, threading may be formed on the outer side surface of the housing 30 and the inner side surface of the mounting member facing the outer side surface to fit each other. Further, one of the outer side surface of the housing portion 30 and the inner side surface of the attachment member 31 may be formed in a concave cross-sectional shape, and the other may be formed in a convex cross-sectional shape so as to be fitted to each other. . In other words, a fitting portion may be formed on one of the outer side surface of the housing portion 30 and the inner side surface of the attachment member 31, and a fitted portion may be formed on the other side.

  The edge 12 supports the diaphragm 11 on the frame 40 so as to freely vibrate, and the outer periphery of the edge 12 is fixed to the frame 40. In the illustrated example, the outer peripheral portion of the edge 12 is supported on the support surface 40 </ b> S of the frame 40. Further, a buffer member 42 and a sound absorbing member 43 are arranged between the outer peripheral portion of the edge 12 and the support surface 40S of the frame 40.

  Here, the edge 12 has a plurality of curved portions 12A, and the curved portion 12A1 disposed on the outer side is formed to have greater rigidity than the curved portion 12A2 disposed on the inner side. More specifically, the bending portion 12A1 disposed on the outer side is formed to be thicker than the bending portion 12A2 disposed on the inner side. According to this, by making the rigidity of the bending portion 12A1 arranged on the outside larger than the bending portion 12A2 arranged on the inside, when the diaphragm 11 vibrates with a relatively small amplitude, the bending portion 12A2 is made more than the bending portion 12A1. Move more flexibly. Further, by making the bending portion 12A1 disposed on the outside more rigid than the bending portion 12A2 disposed on the inside, the vibration is suppressed by applying a braking force when the diaphragm 11 vibrates with an excessive amplitude. The linearity of the edge 12 with respect to the vibration of the voice coil 13 can be improved.

  On the other hand, as shown in FIG. 2, the vibrating body 10 and the magnetic circuit 20 are supported by a frame 40. In addition, a protrusion 30 </ b> D that protrudes toward the magnetic circuit 20 is provided at the bottom of the housing 30 that faces the magnetic circuit 20. The protrusion 30D supports the bottom surface 20A of the magnetic circuit 20. More specifically, the magnetic circuit 20 includes a magnet 21, a plate 22, and a yoke 23, and a protrusion 30 </ b> D included in the housing unit 30 supports a bottom surface 23 </ b> A of the yoke 23. In the illustrated example, the projecting portion 30 </ b> D and the bottom surface portion 23 </ b> A of the yoke 23 are fixed by the fastening member 33. In addition, after arrange | positioning the contact avoidance part 30A in a predetermined position with respect to a to-be-attached member, you may fix the protrusion part 30D and the bottom face part 23A of the yoke 23 with the fastening member 33. FIG. Further, the hole 23B is provided in the yoke 23, the hole 30D1 is provided in the protrusion 30D, a thread is formed on the inner side surface of the hole 23B, and the hole 30D1 in the protrusion 30D and the hole in the yoke 23 are provided with the fastening member 33. The yoke 23 and the housing part 30 may be fixed by being inserted into the part 23B. Further, if necessary, the hole 23B provided in the yoke 23 is a recess into which a part of the fastening member 33 is inserted, or a space between the yoke 23 and the diaphragm 11, and the yoke 23 and the housing 30. It may be a through hole that communicates with the space between them.

  According to this, the housing 30, the frame 40, and the attachment member 31 are in contact with each other, and the bottom surface 20 </ b> A of the magnetic circuit 20 is in contact with the protrusion 30 </ b> D of the housing 30, thereby driving the speaker device 1. Therefore, it is possible to suppress unnecessary vibration that occurs along with this, and it is possible to suppress propagation of unnecessary vibration to the attached member. The diaphragm 11 is supported by the attachment member 31 via the edge 12 and the frame 40. For this reason, for example, the vibration of the diaphragm 11 propagates to the attachment member 31 via the edge 12 and the frame 40, and the vibration propagates from the magnetic circuit 20 to the attachment member 31 via the housing portion 30, whereby the attachment member 31. Both can cancel the vibrations. Therefore, it is possible to suppress unnecessary vibration from propagating to the attached member, and it is possible to suppress generation of unnecessary sound waves by the attached member due to unnecessary vibration.

  Moreover, the rigidity in the vicinity of the bottom part of the housing part 30 can be relatively increased by screwing the bottom part of the housing part 30 to the yoke. For this reason, even if air arranged in an airtight space in the casing 30 is repeatedly compressed and expanded by vibration of the diaphragm, the rigidity in the vicinity of the bottom of the casing is relatively large. It can suppress that a part vibrates and abnormal noise arises.

  Further, by providing a plurality of protruding portions 30E extending in the radial direction or the circumferential direction at the bottom portion of the housing portion 30, the rigidity at the bottom portion of the housing portion 30 can be relatively increased, and the vibration of the housing portion 30 can be increased. Generation of abnormal noise, abnormal noise due to contact between the magnetic circuit 20 and the bottom of the casing 30, or generation of abnormal noise due to contact between the peripheral member 2 </ b> B and the casing 30 can be suppressed. Further, if necessary, the protrusion 30 </ b> D may not be provided on the bottom of the housing 30.

  5 and 6 are explanatory views for explaining assembly and attachment of the speaker device according to the embodiment of the present invention. As shown in FIG. 5, the housing part 30 is inserted into the opening 31 </ b> C of the attachment member 31 from the bottom, and the flange part 30 </ b> C of the housing part 30 is supported by the inner support part 31 </ b> A of the attachment member 31. The vibrating body 10 and the magnetic circuit 20 of the speaker unit 1 </ b> S are housed in the housing 30, and the frame 40 of the speaker unit 1 </ b> S is supported by the outer support portion 31 </ b> B of the attachment member 31. At that time, the bottom surface portion 20 </ b> A of the magnetic circuit (the bottom surface portion 23 </ b> A of the yoke 23) comes into contact with the protruding portion 30 </ b> D of the housing portion 30. Further, a protection unit 41 is mounted on the frame 40 so as to cover the vibrating body 10.

  As shown in FIG. 6, the attachment member 31 includes a frame hole portion 32 corresponding to the hole portion 40 </ b> A of the frame 40 and an attachment member hole portion 34 corresponding to the hole portion of the attachment member 2. Yes. A fastening member (first fastening member) (not shown) is inserted into the hole 40A of the frame 40 and the frame hole 32 of the attachment member 31, and the hole of the attachment member and the attachment member of the attachment member 31 are inserted.
