Description

  The present invention relates to a speaker device.

  Conventionally, for example, a speaker device mounted on an audio device such as a headphone is known (see, for example, Patent Document 1). Many speaker devices include a diaphragm that radiates sound, an edge provided on the outer periphery of the diaphragm, and a frame provided on the outer periphery of the edge.

  FIG. 1 is a diagram illustrating an example of a conventional speaker device.

  In the speaker device 50 shown in FIG. 1, the outer edge area 51 a of the diaphragm 51 is attached to the inner edge area 52 a of the edge 52, and the outer edge area 52 b of the edge 52 is connected to the attachment portion 53 a provided on the frame 53. Yes. A flexible portion 52 c is provided between the outer edge area 52 b and the inner edge area 52 c of the edge 52. Due to the flexibility of the flexible portion 52c, the diaphragm 51 is connected to the frame 53 via the edge 52 so as to freely vibrate.

  Here, the edge 52 is often formed of a relatively soft resin, a rubber-based member, or the like so that good flexibility can be obtained by the flexible portion 52c. On the other hand, the frame 53 is often formed of a relatively hard resin, metal, or the like in order to support an object such as a magnetic circuit. As described above, the edge 52 and the frame 53 are often made of different materials.

  For the connection of the outer edge region 52b of the edge 52 to the attachment portion 53a of the frame 53, adhesion by an adhesive is often employed. At this time, depending on the combination of the materials of the edge 52 and the frame 53, for example, even if the outer edge region 52b of the edge 52 is directly bonded to the mounting portion 53a of the frame 53, a desired bonding strength may not be obtained.

  Therefore, as shown in FIG. 1, a connection member 54 made of, for example, paper or resin is sandwiched between the outer edge region 52b of the edge 52 and the attachment portion 53a to obtain good adhesive strength with respect to both. Adhesion has been proposed (see, for example, Patent Document 2).

  Incidentally, in recent years, there has been an increasing demand for downsizing of speaker devices. On the other hand, from the viewpoint of sound quality, there is a demand for making the diaphragm and edge as wide as possible.

  In response to these requests, for example, when the speaker device 50 shown in FIG. 1 is reduced in size without sacrificing the width of the diaphragm 51 or the edge 52, the outer edge region 52b of the edge 52 and the attachment portion 53a are attached to each other. The width of the margin may be less than 1 mm, for example. In such a case, the width of the connecting member 54 is often less than 1 mm in accordance with the width of the pasting.

  However, the work of bonding the outer edge region of the edge to the attachment portion of the frame with a thin connection member having a width of, for example, less than 1 mm is often difficult in the manufacturing process.

  For this reason, in the speaker device as shown in FIG. 1, when the size of the speaker device is reduced without sacrificing the width of the diaphragm or the edge, a desired strength is obtained for the connection between the outer edge region of the edge and the attachment portion of the frame. The problem that it may not be obtained is an example. In addition, although the thing of width less than 1 mm was illustrated as an example of a thin connection member, the dimension of less than 1 mm is an illustration to the last, Comprising: Depending on conditions, such as a raw material of an edge, even if the width of a connection member is 1 mm or more, it is the said. Problems can occur.

  Accordingly, the present invention provides a speaker device capable of obtaining high strength in connection between the outer edge region of the edge and the mounting portion of the frame, while being reduced in size without sacrificing the area of the diaphragm or the edge. Is an issue.

  In order to solve the above problems, the invention described in claim 1 is directed to a diaphragm that emits sound, an edge provided on an outer periphery of the diaphragm, an outer edge region of the edge, and the outer edge region. A connecting member disposed between the mounting member and the connecting member, wherein the connecting member has a width wider than the outer edge region, and an inner diameter of the connecting member is smaller than an inner diameter of the outer edge region. This is a speaker device.

It is a figure which shows an example of the conventional speaker apparatus. It is a figure which shows the speaker apparatus of 1st Example along with the conventional speaker apparatus of FIG. It is an enlarged view of the adhesion location of an edge and a frame in the speaker apparatus of 1st Example. It is a figure which shows the speaker apparatus of 2nd Example along with the conventional speaker apparatus of FIG. It is a figure which shows the speaker apparatus of 3rd Example paying attention to the adhesion location of an edge and a flame | frame.

Hereinafter, a speaker device according to an embodiment of the present invention will be described. A speaker device according to an embodiment of the present invention includes a diaphragm that radiates sound and an edge provided on an outer periphery of the diaphragm. The speaker device further includes a connecting member disposed between an outer edge region of the edge and an attachment portion disposed to face the outer edge region. In this speaker device, the width of the connection member is wider than the width of the outer edge region, and the inner diameter of the connection member is smaller than the inner diameter of the outer edge region.
Further, it is preferable that the attachment portion is provided on a metal part that supports a magnetic circuit for vibrating the diaphragm.
It is also preferable that the outer periphery of the connection member has a shape along the outer periphery of the edge.
It is also preferable that the outer periphery of the connection member has a shape along the outer periphery of the edge.
It is also preferable that the outer diameter of the connecting member is substantially equal to the outer diameter of the edge.
In addition, it is preferable that the connection member is bonded to the outer edge region and the attachment portion.
It is also preferable that the connecting member is annular.
It is also preferable that the edge is made of resin and the attachment portion is made of metal.

  In addition, it is preferable that the connection member has a width wider than that of the attachment portion and an inner diameter thereof is smaller than an inner diameter of the attachment portion. Thereby, the difficulty in a manufacturing process is reduced also about adhesion | attachment with the attachment part of a connection member and a flame | frame. As a result, the difficulty in the manufacturing process for the connection between the outer edge region of the edge and the attachment portion of the frame is further reduced, and a higher strength can be obtained for this connection.

  It is also preferable that the outer diameter of the connection member is substantially equal to the outer diameter of the edge. Thereby, for example, the positioning accuracy of the edge with respect to the frame can be increased as compared with the case where the outer edge of the connecting member and the outer edge of the edge are greatly displaced.

  It is also preferable that the outer diameter of the connection member is substantially equal to the outer diameter of the attachment portion. Thereby, for example, the positioning accuracy of the edge with respect to the frame at the time of manufacture can be improved as compared with a case where the outer edge of the connecting member and the outer edge of the attachment portion are greatly displaced.

  Further, the connection member may be bonded to a surface on the sound emission side of the attachment portion, and may be bonded to a surface opposite to the sound emission side in the outer edge region of the edge. As a result, the worker can perform the bonding work from an access direction that is easy for the worker, such as placing the outer edge region of the edge to which the connecting member is bonded on the attachment portion of the frame from above.

  Further, the speaker device includes a magnetic circuit and a voice coil that is supplied with an audio signal and vibrates the diaphragm by receiving an action from the magnetic circuit. There may be. That is, the frame has air holes that allow air to flow back and forth between the outer surface of the edge opposite to the sound radiation side, the outer surface of the voice coil, and the space surrounded by the inner surface of the frame. It may be in the form of being provided. By providing such a vent hole in the frame, the air permeability of the air in the space to the outside of the space is ensured during vibration of the diaphragm, and the temperature rise of the magnetic circuit is suppressed. Here, by using the wide connection member as described above, the difficulty in the manufacturing process for the adhesion between the outer edge region of the edge and the attachment portion of the frame is reduced. For this reason, it is possible to widen the space in the frame by, for example, slightly reducing the width of the mounting portion in anticipation of such a difficulty reduction. As a result, it is possible to increase the size of the vent hole and improve the air permeability of the air in the space to the outside of the space.

  A speaker device 10 according to a first embodiment of the present invention will be described with reference to FIGS.

  Part (A) of FIG. 2 shows the conventional speaker device 50 shown in FIG. 1 for comparison with the speaker device 10 according to the first embodiment. And the speaker apparatus 10 which concerns on 1st Example is shown by Part (B) of FIG. FIG. 3 shows an enlarged view of a connection portion between the edge 12 and the frame 13 in the speaker device 10 shown in Part (B) of FIG.

  In FIG. 2 (A), components equivalent to those of the speaker device 10 of the first embodiment shown in Part (B) of FIG. 2, such as a magnetic circuit, are shown in Part (B) of FIG. ) And the same reference numerals. In the following, these equivalent components are referred to only in the description of the speaker device 10 of the first embodiment, and the description of the conventional speaker device 50 is omitted.

  As shown in FIG. 2, the speaker device 10 includes a diaphragm 11, an edge 12, a frame 13, a magnetic circuit 14, a voice coil bobbin 15, and a voice coil 16.

  The speaker device 10 is a so-called dome-shaped speaker device in which a diaphragm 11 that emits sound has a dome shape. The edge 12 is provided on the outer periphery of the diaphragm 11, and the frame 13 is provided on the outer periphery of the edge 12.

  In the speaker device 10, the outer edge region 11 a of the diaphragm 11 is overlapped and bonded to the surface of the inner edge region 12 a of the edge 12 opposite to the sound emission side. Further, the outer edge region 12 b of the edge 12 is connected to the sound emission side of the attachment portion 13 a provided on the frame 13. The attachment portion 13 a is an annular recess provided on the inner side at the end of the frame 13 on the sound emission side. The outer edge region 12b of the edge 12 is fitted into the attachment portion 13a. Between the outer edge region 12b and the inner edge region 12c of the edge 12, a flexible portion 12c that is convexly curved toward the sound radiation side is provided. Due to the flexibility of the flexible portion 12c, the diaphragm 11 is connected to the frame 13 via the edge 12 so as to freely vibrate. In this embodiment, the edge 12 is an up-roll type edge in which the flexible portion 12c is curved convexly toward the sound radiation side as described above.

  The magnetic circuit 14 includes a magnet 14a, a yoke 14b through which magnetism from the magnet 14a passes, and a plate 14d. The outer periphery of the yoke 14 b is fixed to the inner wall of the frame 13. An annular magnetic gap 14c is provided between the yoke 14b and the plate 14d. A voice coil 16 wound around a voice coil bobbin 15 is accommodated in the magnetic gap 14c. The surface opposite to the sound emission side in the outer edge region 11 a of the diaphragm 11 is fixed to the end of the voice coil bobbin 15 on the sound emission side.

  When a voice signal is supplied to the voice coil 16, a Lorentz force by magnetism from the magnetic circuit 14 acts on the voice coil 16 in accordance with the voice signal. As a result, the voice coil 16 vibrates, and the vibration is transmitted to the diaphragm 11 via the voice coil bobbin 15. And the diaphragm 11 radiates | emits a sound by the vibration.

  The diaphragm 11 shown in part (B) of FIG. 2 corresponds to an example of the diaphragm according to the present invention, the edge 12 corresponds to an example of the edge according to the present invention, and the frame 13 corresponds to the frame according to the present invention. It corresponds to an example. The magnetic circuit 14 corresponds to an example of a magnetic circuit according to the present invention, the voice coil 16 corresponds to an example of a voice coil according to the present invention, and the frame 13 corresponds to an example of a frame according to the present invention. .

  Further, a ventilation hole 13b for allowing air to flow back and forth between the surface of the edge 12 opposite to the sound radiation side, the outer surface of the voice coil 16 and the space surrounded by the inner surface of the frame 13 and the outside of the frame 13 is provided in the frame 13. Is provided. The ventilation hole 13b ensures the air permeability of the air in the space to the outside of the space when the diaphragm 12 vibrates, and the temperature rise of the magnetic circuit 14 can be suppressed. In FIG. 2, a part of the ventilation hole 13 b that is not hidden by the voice coil bobbin 15 or the voice coil 16 is illustrated.

  Here, the edge 12 is formed of a relatively soft resin, a rubber-based member, or the like so that good flexibility can be obtained by the flexible portion 12c. On the other hand, the frame 13 is formed of a relatively hard resin, metal, or the like to support the magnetic circuit 14. A connection member 17 is sandwiched between the outer edge region 12 b of the edge 12 and the attachment portion 13 a of the frame 13. The connecting member 17 is formed in an annular shape, for example, from paper or resin, which can provide good adhesive strength to both the outer edge region 12b of the edge 12 and the attachment portion 13a. The connection member 17 is adhered to the surface on the sound emission side of the attachment portion 13 a and is adhered to the surface opposite to the sound emission side of the outer edge region 12 b of the edge 12.

  A manufacturing process in this example will be described. First, the outer edge region 11 a of the diaphragm 11 is bonded to the inner edge region 12 a of the edge 12. Further, the connection member 17 is bonded to the surface of the outer edge region 12b of the edge 12 opposite to the sound emission side. Thereafter, the edge 12 with the connecting member 17 is placed on and adhered to the sound radiation side surface of the mounting portion 13a of the frame 13. In the speaker device 10 according to the present embodiment, the connection to the mounting portion 13a of the outer edge region 12b of the edge 12 is performed by the adhesive work from the access direction that is easy for the operator.

  In the present embodiment, as shown in FIG. 3, the width A1 of the connecting member 17 is wider than the width A2 of the outer edge region 12b of the edge 12, and protrudes to the inner peripheral side of the outer edge region 12b. Further, the width A1 of the connection member 17 is wider than the width A3 of the attachment portion 13a of the frame 13, and also protrudes to the inner peripheral side of the attachment portion 13a.

  Further, the outer diameter of the connection member 17 is formed to be equal to the outer diameter of the edge 12. As a result, the outer edge of the connecting member 17 is substantially aligned with the outer edge of the edge. Further, the outer diameter of the connecting member 17 is substantially equal to the outer diameter of the mounting portion 13a, leaving a gap with the inner wall of the frame 13 required when the edge 12 with the connecting member 17 is placed on the mounting portion 13a. Is formed. For this reason, the outer edge of the connection member 17 is substantially aligned with the outer edge of the attachment portion 13a.

  Here, although the conventional speaker device 50 shown in part (A) of FIG. 2 is reduced in size, the diaphragm 51 and the flexible portion 52c of the edge 52 are narrowed in the downsizing. Thereby, the narrowing of the sticking margin between the outer edge region 52b of the edge 52 and the attachment portion 53a of the frame 53 is avoided. In this conventional speaker device 50, the width of the adhesive member 54 is substantially equal to the width of the outer edge region 52b of the edge 52, and is also substantially equal to the width of the attachment portion 53a.

  In contrast, in the speaker device 10 of the present embodiment shown in Part (B) of FIG. 2, the diaphragm 11 has the same width as the diaphragm 51 of the conventional speaker device 50, but the edge 12 can be formed. The flexible portion 12c is downsized while ensuring a desired area. For this reason, the width of the outer edge region 12 b of the edge 12 is narrower than the width of the outer edge region 52 b of the edge 52 in the conventional speaker device 50. In accordance with this, the width of the attachment portion 13a of the frame 13 is also narrower than the width of the attachment portion 53a of the frame 53 in the conventional speaker device 50. On the other hand, the width of the connecting member 17 remains as wide as the width of the connecting member 54 in the conventional speaker device 50.

  In the conventional speaker device 50, as described above, the width of the adhesive member 54 is substantially equal to the width of the outer edge region 12b of the edge 52 and the width of the attachment portion 53a. For this reason, as in the speaker device 10 of the present embodiment, when the downsizing is performed without sacrificing the width of the flexible portion 52c of the edge 52, the width of the connecting member 54 is set to the outer edge region 52b. And the width of the mounting portion 53a is substantially equal and narrow. When the speaker device 50 is downsized without sacrificing the size of the diaphragm 51 or the flexible portion 52c of the edge 52, the width of the connection member 54 may be less than 1 mm. The operation of connecting the outer edge region 52b of the edge 52 to the mounting portion 53a of the frame 53 with the thin connection member 54 having a width of less than 1 mm is often difficult in the manufacturing process. When the width of the connection member 54 is narrow, there may be a problem that high strength cannot be obtained for the connection between the outer edge region 52b of the edge 52 and the attachment portion 53a of the frame 53. In addition, as an example of the thin connection member, a member having a width of less than 1 mm is illustrated here. However, the dimension of less than 1 mm is merely an example, and even if the width of the connection member is 1 mm or more, the material of the edge 52, etc. The above problems may occur depending on the conditions. In the conventional speaker device 50, in order to avoid such a problem, as described above, the width of the flexible portion 52c of the edge 52 is narrowed, and thus the width of the connecting member 54 is prevented from being narrowed.

  On the other hand, in the speaker device 10 of this embodiment shown in Part (B) of FIG. 2, the width of the connecting member 17 is conventionally reduced while reducing the size without sacrificing the width of the flexible portion 12 c of the edge 12. The width is as large as that of the connection member 54 of the speaker device 50. Thereby, in the speaker device 10 of the present embodiment, the connection member 17 has a width wider than the width of the outer edge region 12b of the edge 12, and projects to the inner peripheral side of the outer edge region 12b. In the speaker device 10, by using such a wide connection member 17, first, the difficulty in the manufacturing process for bonding the outer edge region 12 b of the edge 12 and the connection member 17 is reduced. As a result, the difficulty in the manufacturing process for the connection between the outer edge region 12b of the edge 12 and the mounting portion 13a of the frame 13 is reduced. As a result, in this embodiment, the strength of the connection between the outer edge region 12b of the edge 12 and the mounting portion 13a of the frame 13 is high, while achieving a reduction in size without sacrificing the width of the flexible portion 12c of the edge 12. It is supposed to be obtained.

  Further, in the speaker device 10 of the present embodiment, the connecting member 17 is wider than the attachment portion 13a and protrudes to the inner peripheral side of the attachment portion 13a. Thereby, in the speaker device 10, the difficulty in the manufacturing process is reduced with respect to the bonding between the connection member 17 and the attachment portion 13 a of the frame 13. As a result, the difficulty in the manufacturing process of the connection between the outer edge region 12b of the edge 12 and the attachment portion 13a is further reduced, and a higher strength can be obtained for this connection.

  Further, in the speaker device 10 of the present embodiment, the outer diameter of the connection member 17 is formed to be equal to the outer diameter of the edge 12 as described above. As a result, the outer edge of the edge 12 and the outer edge of the connecting member 17 are substantially aligned. As a result, in the speaker device 10 of the present embodiment, the positioning accuracy of the edge 17 with respect to the frame 13 at the time of manufacture is improved as compared with, for example, a case where the outer edge of the edge 12 and the outer edge of the connecting member 17 are greatly displaced. Yes.

  Further, in the speaker device 10 of the present embodiment, as described above, the outer diameter of the connection member 17 is formed to be approximately equal to the outer diameter of the attachment portion 13a. Thereby, the outer edge of the attachment part 13a and the outer edge of the connection member 17 will be substantially aligned. As a result, in the speaker device 10 of the present embodiment, the positioning accuracy of the edge 12 with respect to the frame 13 at the time of manufacture is improved as compared with, for example, a case where the outer edge of the attachment portion 13a and the outer edge of the connection member 17 are greatly displaced. ing.

  Further, in the speaker device 10 of the present embodiment, air flows back and forth between the space surrounded by the surface opposite to the sound emission side at the edge 12, the outer surface of the voice coil 16, and the inner surface of the frame 13 and the outside of the frame 13. The vent hole 13b is provided to suppress the temperature rise of the magnetic circuit 14.

  A similar vent hole 53b is also provided in the frame 53 of the conventional speaker device 50 shown in Part (A) of FIG. However, in this embodiment, the width of the attachment portion 13a of the frame 13 is narrowed in accordance with the width of the outer edge region 12b of the edge 12. As a result, in the present embodiment, the space in which the air flowing back and forth through the vent hole 13b is accumulated is larger than the similar space in the conventional speaker device 50. In this embodiment, in response to this, the vent hole 13b is formed larger than the vent hole 53b in the conventional speaker device 50. Thus, in this embodiment, the air permeability of the air in the space is improved with respect to the conventional speaker device 50, and the temperature rise of the magnetic circuit 14 is suppressed.

  This is the end of the description of the speaker device 10 according to the first embodiment. Next, the speaker device according to the second embodiment will be described with reference to FIG.

  Part (A) of FIG. 4 shows the conventional speaker device 50 shown in FIG. 1 for comparison with the speaker device 20 according to the second embodiment. And the speaker apparatus 20 which concerns on 2nd Example is shown by the part (B) of FIG.

  The speaker device 20 of the second embodiment is different from the speaker device 10 of the first embodiment in the shapes of the diaphragm 21 and the edge 22. Hereinafter, the speaker device 20 of the second embodiment will be described by paying attention to differences from the speaker device 10 of the first embodiment.

In the following, redundant description of these equivalent components is omitted.

  In the speaker device 20 of the second embodiment, the flexible portion 22c of the edge 22 is as large as the flexible portion 52c of the conventional speaker device 50, while ensuring a desired width for the diaphragm 21. However, miniaturization has been made. For this reason, the position of the outer edge region 21 a of the diaphragm 21 is shifted to the frame 13 side from the position of the outer edge region 51 a of the diaphragm 51 of the conventional speaker device 50. In accordance with this, in the present embodiment, the position of the flexible portion 22c is shifted to the frame 13 side from the position of the flexible portion 52c of the conventional speaker device 50. As a result, the width of the outer edge region 22b of the edge 22 is narrower than the width of the outer edge region 52b of the edge 52 in the conventional speaker device 50.

  The narrow outer edge region 22b is connected to the mounting portion 13a of the frame 13 through the wide connecting member 17 as in the first embodiment. Thereby, the difficulty in a manufacturing process is reduced about the connection via the connection member 17 to the attaching part 13a of the outer edge area | region 22b of the edge 22. FIG. As a result, in the present embodiment, high strength can be obtained with respect to the connection between the outer edge region 22b of the edge 22 and the attachment portion 13a of the frame 13 while reducing the size without sacrificing the area of the diaphragm 21.
