[0001] The present disclosure relates to a speaker.

[0002] Patent Document 1 discloses a speaker equipped with two terminal fittings, each of which has a protruding plate portion that is press-fitted into a groove formed in a connecting terminal.

[0003] JP 2022-139884 A

[0004] In a speaker provided with the above-described protruding plate portion, there is a risk that the protruding plate portion may come into contact with an operator's finger or other object, causing deformation of the terminal fitting (terminal) having the protruding plate portion.

[0005] An object of the present disclosure is to provide a speaker that can suppress deformation of a terminal while ensuring workability in connecting a mating terminal.

[0006] A speaker according to a first aspect is a speaker comprising a first terminal and a second terminal, wherein the first terminal is a first pin-shaped connecting portion extending toward one side in the X direction, and has the first pin-shaped connecting portion to which a first mating terminal is connected from one side in the Y direction, which is a direction perpendicular to the X direction, and the second terminal is a second pin-shaped connecting portion extending toward one side in the X direction, and has the second pin-shaped connecting portion to which a second mating terminal is connected from one side in the Y direction, the first pin-shaped connecting portion and the second pin-shaped connecting portion form a pair of pin-shaped connecting portions aligned in the Z direction, which is a direction perpendicular to both the X direction and the Y direction, and the speaker further comprises a protective wall that is provided in a direction perpendicular to the Y direction with respect to the pair of pin-shaped connecting portions and protects the pair of pin-shaped connecting portions.

[0007] In this aspect, the speaker includes a first terminal and a second terminal. The first terminal has a first pin-shaped connecting portion extending toward one side in the X direction, and the second terminal has a second pin-shaped connecting portion extending toward one side in the X direction. The first pin-shaped connecting portion is connected to a first mating terminal from one side in the Y direction, and the second pin-shaped connecting portion is connected to a second mating terminal from one side in the Y direction. The first pin-shaped connecting portion and the second pin-shaped connecting portion form a pair of pin-shaped connecting portions aligned in the Z direction.

[0008] However, in a speaker provided with such a pair of pin-shaped connecting portions, there is a risk that the pin-shaped connecting portions may come into contact with an operator's fingers or other objects, causing deformation of the terminals. Therefore, in this aspect, the speaker is provided with a protective wall that protects the pair of pin-shaped connecting portions. The protective wall protects the pin-shaped connecting portions from contact with fingers and other objects, thereby suppressing deformation of the terminals. Furthermore, in this aspect, the protective wall is provided in a direction perpendicular to the Y direction with respect to the pair of pin-shaped connecting portions. This allows connection of a mating terminal from one side in the Y direction.

[0009] As described above, according to this aspect, it is possible to suppress deformation of the terminal while ensuring the workability of connecting the mating terminal.

[0010] In the embodiments described below, the protective wall is molded integrally with a frame included in the speaker. However, the protective wall is not limited to this and may be formed separately from the frame included in the speaker. Also, in the embodiments described below, the protective wall is provided so as to surround the pair of pin-shaped connection portions. However, the protective wall is not limited to this. Also, in the embodiments described below, one side in the X direction, which is the direction in which the first pin-shaped connection portion and the second pin-shaped connection portion extend, is a direction perpendicular to the central axis of the speaker. In other words, the pair of pin-shaped connection portions extend in a direction perpendicular to the central axis of the speaker. However, the "one side in the X direction" in this embodiment is not limited to this and may be, for example, a direction parallel to the central axis of the speaker.

[0011] A speaker according to a second aspect is the speaker according to the first aspect, wherein the protective wall includes a side wall provided on one side or the other side in the Z direction with respect to the pair of pin-shaped connection portions.

[0012] In this aspect, the protective wall includes a side wall provided on one or the other side of the pair of pin-shaped connection portions in the Z direction, so that the side wall can prevent fingers or the like from touching the pair of pin-shaped connection portions from one or the other side in the Z direction.

[0013] In the embodiment described below, the side walls extend linearly when viewed in the Y direction. However, the side walls are not limited to this, and may extend in an arc shape when viewed in the Y direction, for example. In the embodiment described below, the protective wall includes a pair of side walls provided on one side and the other side in the Z direction with respect to the pair of pin-shaped connecting portions. However, the protective wall of this aspect is not limited to this.

[0014] A speaker according to a third aspect is the second aspect, wherein the side walls hide at least a portion of the pair of pin-shaped connecting portions when viewed from one side or the other side in the Z direction.

[0015] In this aspect, the side walls conceal at least a portion of the pair of pin-shaped connections when viewed from one side or the other side in the Z direction, which makes it possible to more effectively protect the pair of pin-shaped connections than in an aspect in which the side walls do not conceal the pair of pin-shaped connections when viewed from the same direction.

[0016] In the embodiment described below, the side walls hide the entire pair of pin-shaped connecting portions when viewed from one side or the other side in the Z direction, but the side walls of this aspect are not limited to this.

[0017] A fourth aspect of the present invention is a speaker according to the first aspect, wherein the protective wall includes a front wall provided on one side in the X direction with respect to the pair of pin-shaped connection portions.

[0018] In this aspect, the protective wall includes a front wall provided on one side in the X direction of the pair of pin-shaped connections, so that the front wall can prevent fingers or the like from touching the pair of pin-shaped connections from one side in the X direction.

[0019] In the embodiment described below, the front wall extends linearly when viewed in the Y direction. However, the front wall is not limited to this, and may extend in an arc shape when viewed in the Y direction, for example.

[0020] A speaker according to a fifth aspect is the speaker of the fourth aspect, wherein the front wall hides at least a part of the pair of pin-shaped connecting portions when viewed from one side in the X direction.

[0021] In this embodiment, the front wall conceals at least a portion of the pair of pin-shaped connecting portions when viewed from one side in the X direction, thereby providing more effective protection for the pair of pin-shaped connecting portions than in an embodiment in which the front wall does not conceal the pair of pin-shaped connecting portions when viewed from the same direction.

[0022] In the embodiment described below, the front wall hides the entire pair of pin-shaped connecting portions when viewed from one side in the X direction, but the front wall of this embodiment is not limited to this.

[0023] In the speaker of the sixth aspect, in the first aspect, the protective wall comprises a pair of side walls provided on one side and the other side of the pair of pin-shaped connection portions in the Z direction, and a front wall provided on one side of the pair of pin-shaped connection portions in the X direction.

[0024] In this aspect, the protective wall includes a pair of side walls and a front wall, which makes it possible to more effectively protect the pair of pin-shaped connecting portions.

[0025] In the embodiment described below, the front wall connects the tips of the pair of side walls (the ends on one side in the X direction) in the Z direction, but the front wall of this aspect is not limited to this.

[0026] A seventh aspect of the present invention is a speaker according to the sixth aspect, wherein the protective wall has an intermediate wall that is provided between the pair of pin-shaped connecting portions when viewed from the Y direction and that connects to the front wall.

[0027] In this aspect, the protective wall has an intermediate wall that is provided between the pair of pin-shaped connecting portions when viewed from the Y direction and that connects to the front wall, so that the protective wall can be reinforced by the intermediate wall.

[0028] The speaker according to the eighth aspect is any one of the first to seventh aspects, in which the other end of the protective wall in the Y direction is located on the other side of the Y direction than the other ends of the pair of pin-shaped connection parts in the Y direction.

[0029] In this aspect, the other end of the protective wall in the Y direction is located on the other side in the Y direction of the other ends of the pair of pin-shaped connecting portions, thereby effectively preventing fingers or the like from touching the pair of pin-shaped connecting portions from the other side in the Y direction.

[0030] In the embodiment described below, the pair of side walls have surfaces that extend in a plane perpendicular to the Y direction and face the other side in the Y direction, and these surfaces constitute the other end of the protective wall in the Y direction. However, the protective wall of this aspect is not limited to this. In the embodiment described below, the other end of the protective wall in the Y direction is the other end of the side wall in the Y direction, not the other end of the front wall in the Y direction. In the embodiment described below, at any position in the X direction where the pin-shaped connection portion extends, the other end of the protective wall (side wall) in the Y direction is located on the other side in the Y direction of the other end of the pin-shaped connection portion. However, the protective wall of this aspect is not limited to this.

[0031] The speaker of the ninth aspect is any one of the first to seventh aspects, in which the end of the protective wall on one side in the Y direction is located on one side in the Y direction of the ends of the pair of pin-shaped connection parts on one side in the Y direction.

[0032] In this aspect, the one end of the protective wall in the Y direction is located on one side of the one end of the pair of pin-shaped connections in the Y direction, which effectively prevents fingers or the like from touching the pair of pin-shaped connections from one side in the Y direction.

[0033] The speaker of the tenth aspect is any one of the first to seventh aspects, in which the end of the protective wall on the other side in the Y direction is located on the other side in the Y direction of the end of the pin-shaped connection portion on the other side in the Y direction, and the end of the protective wall on one side in the Y direction is located on one side in the Y direction of the end of the pin-shaped connection portion on one side in the Y direction.

[0034] In this aspect, the end of the protective wall on the other side in the Y direction is located on the other side in the Y direction of the end of the pin-shaped connection portion on the other side in the Y direction, and the end of the protective wall on one side in the Y direction is located on one side in the Y direction of the end of the pin-shaped connection portion on one side in the Y direction. This makes it possible to effectively prevent fingers, etc. from touching the pin-shaped connection portion from the other side in the Y direction, and also effectively prevent fingers, etc. from touching the pin-shaped connection portion from the one side in the Y direction.

[0035] A speaker according to an eleventh aspect is any one of the first to tenth aspects, wherein the protective wall supports a portion of one side in the X direction of at least one of the first pin-shaped connection portion and the second pin-shaped connection portion.

[0036] In this aspect, the protective wall supports a portion of at least one of the first pin-shaped connecting portion and the second pin-shaped connecting portion on one side in the X direction, thereby more effectively suppressing deformation of the terminal.

[0037] In the embodiment (modification) described later, the protective wall supports a portion of one side in the X direction of both the first pin-shaped connecting portion and the second pin-shaped connecting portion. However, the protective wall of this embodiment is not limited to this. In the embodiment (modification) described later, the protective wall is insert-molded using the first terminal and the second terminal as insert parts, so that the protective wall supports a portion of one side in the X direction of at least one of the first pin-shaped connecting portion and the second pin-shaped connecting portion. However, the protective wall of this embodiment is not limited to this. For example, the protective wall may be molded separately from the first terminal and the second terminal, and then the first terminal and the second terminal may be attached to the protective wall, thereby supporting the first pin-shaped connecting portion and the second pin-shaped connecting portion.

[0038] Fig. 1 is an enlarged perspective view of the periphery of a protective wall in a speaker according to an embodiment; Fig. 2 is a view of the speaker as seen from the rear side (one side in the Y direction); Fig. 3 is a view of the speaker as seen from the side (one side in the X direction); Fig. 4 is a view of the speaker as seen from the side (one side in the Z direction); Fig. 5 is a partially enlarged view of a speaker according to a modified example;

[0039] A speaker 10 according to an embodiment will be described below with reference to the drawings.

[0040] One side of the central axis AX of the speaker 10 is referred to as the front side, and the other side of the central axis AX is referred to as the rear side. The speaker 10 is configured to emit sound forward. The downward direction in Figures 3 and 4 is the front direction of the speaker 10. In addition, in a direction perpendicular to the central axis AX, the side closer to the central axis AX is referred to as the radially inner side, and the side away from the central axis AX is referred to as the radially outer side.

[0041] In the following description, the terms X direction, Y direction, and Z direction may be used to refer to three mutually perpendicular directions. In this embodiment, the Y direction is a direction parallel to the central axis AX of the speaker 10.

[0042] As shown in FIGS. 2 to 4, the speaker 10 includes a vibrating section 20, a magnetic circuit 30, and a frame 40 that supports the vibrating section 20 and the magnetic circuit 30.

[0043] The vibration unit 20 is a part that vibrates in the front-to-rear direction due to the magnetic interaction with the magnetic circuit 30, and has a diaphragm 22. Sound is produced when the diaphragm 22 vibrates. Specifically, the vibration unit 20 includes the diaphragm 22, an edge 24 that supports the outer edge of the diaphragm 22, a voice coil, and an elastic support part 28 (damper) that elastically supports the voice coil.

[0044] The magnetic circuit 30 is configured by combining a magnet and a magnetic member. Specifically, the magnetic circuit 30 includes a top plate, a magnet, and a yoke 36. A portion of the yoke 36 protrudes rearward from the frame 40.

[0045] The frame 40 is integrally molded from resin. The frame 40 includes a first support portion 41 that supports the outer edge of the edge 24, a second support portion 42 that supports the magnetic circuit 30, and a plurality of connecting portions 43 that connect the first support portion 41 and the second support portion 42. The second support portion 42 also supports the outer edge of the elastic support portion 28. The first support portion 41 is formed in an annular shape surrounding the central axis AX of the speaker 10, and the second support portion 42 is also formed in an annular shape surrounding the central axis AX of the speaker 10. The plurality of connecting portions 43 are provided at intervals in the circumferential direction.

[0046] As shown in FIG. 1, the speaker 10 includes a first terminal 50A and a second terminal 50B.

[0047] The first terminal 50A and the second terminal 50B have a similar structure. Specifically, the first terminal 50A and the second terminal 50B have a symmetrical structure (a symmetrical structure in the Z direction in this embodiment) with respect to a plane including the central axis AX of the speaker 10. Hereinafter, when the first terminal 50A and the second terminal 50B are described without any particular distinction, they will be simply referred to as terminals 50.

[0048] The terminals 50 have held portions 52 that are held by the frame 40. The frame 40 has terminal holding portions 44 that hold the held portions 52 of the two terminals 50.

[0049] Specifically, the terminal holding portion 44 is provided so as to protrude radially outward from a portion of the second support portion 42 in the circumferential direction. The terminal holding portion 44 has protrusions 44a for positioning the terminal 50. The protrusions 44a include two protrusions 44a for positioning the first terminal 50A and two protrusions 44a for positioning the second terminal 50B. The two protrusions 44a are aligned in the X direction. Through holes are formed in the held portion 52 of the terminal 50, and the protrusions 44a are inserted into the through holes. The speaker 10 also has a holding metal fitting 70 for holding the terminal 50. The holding metal fitting 70 is press-fitted into the terminal holding portion 44 of the frame 40 from the rear side and functions to press the held portion 52 of the terminal 50. The holding metal fitting 70 has notches in which the protrusions 44a are disposed.

[0050] The frame 40 has a vertical wall 45 that connects the terminal holding portion 44 and the first support portion 41. The terminal holding portion 44 and the vertical wall 45 connect the first support portion 41 and the second support portion 42.

[0051] The terminals 50 have pin-shaped connecting portions 51 extending toward one side in the X direction. Specifically, the first terminal 50A has a first pin-shaped connecting portion 51A extending toward one side in the X direction, and the second terminal 50B has a second pin-shaped connecting portion 51B extending toward one side in the X direction. The first pin-shaped connecting portion 51A is connected to a first mating terminal 90A from one side in the Y direction, which is the front side of the speaker 10, and the second pin-shaped connecting portion 51B is connected to a second mating terminal 90B from one side in the Y direction. The first pin-shaped connecting portion 51A and the second pin-shaped connecting portion 51B constitute a pair of pin-shaped connecting portions 51A, 51B aligned in the Z direction.

[0052] The terminal 50 has an internal connection portion 53. An electric wire (not shown), such as a tinsel wire, that is connected to the voice coil is connected to the internal connection portion 53. The thickness direction of the internal connection portion 53 faces the X direction. The internal connection portion 53 has a notch for connection with the electric wire, and the notch opens inward in the Z direction.

[0053] The frame 40 has an intervening wall 46 that is interposed between the internal connection portion 53 of the first terminal 50A and the internal connection portion 53 of the second terminal 50B to prevent a short circuit. The intervening wall 46 is erected on the other side in the Y direction from the terminal holding portion 44, and its thickness direction is oriented in the Z direction.

[0054] (Protective Wall 60) Speaker 10 includes protective wall 60 that protects pair of pin-shaped connection portions 51A, 51B. Protective wall 60 protects pair of pin-shaped connection portions 51A, 51B from contact with fingers or the like and functions to suppress deformation of terminals 50. Protective wall 60 is provided in a direction perpendicular to the Y direction relative to pair of pin-shaped connection portions 51A, 51B so as to allow connection of mating terminals 90A, 90B from one side in the Y direction.

[0055] One side in the X direction, which is the direction in which the first pin-shaped connection portion 51A and the second pin-shaped connection portion 51B extend, is parallel to a line perpendicular to the central axis AX of the speaker 10. In other words, the pair of pin-shaped connection portions 51A, 51B extend in a direction perpendicular to the central axis AX of the speaker 10.

[0056] The protective wall 60 includes a pair of side walls 61 provided on one side and the other side in the Z direction of the pair of pin-shaped connections 51A, 51B. As shown in Fig. 2, the side walls 61 extend linearly when viewed from the Y direction. As shown in Fig. 4, the side walls 61 hide the entire pair of pin-shaped connections 51A, 51B when viewed from one side or the other side in the Z direction. The cross-sectional shape of the side walls 61 (the cross-sectional shape perpendicular to the direction in which the side walls 61 extend) is a shape with the Y direction as its longitudinal axis (specifically, a rectangular shape).

[0057] The protective wall 60 includes a front wall 62 provided on one side in the X direction of the pair of pin-shaped connections 51A, 51B. As shown in FIG. 2 , the front wall 62 extends linearly when viewed from the Y direction. As shown in FIG. 3 , the front wall 62 completely conceals the pair of pin-shaped connections 51A, 51B when viewed from one side in the X direction. The front wall 62 connects the tips of the pair of side walls 61 (the ends on one side in the X direction) in the Z direction. This allows the protective wall 60 to surround the pair of pin-shaped connections 51A, 51B from the periphery. The cross-sectional shape of the front wall 62 (the cross-sectional shape perpendicular to the extension direction of the front wall 62) is a shape whose longitudinal axis is in the Y direction (specifically, a rectangular shape).

[0058] The protective wall 60 has an intermediate wall 63 that is provided between the pair of pin-shaped connecting portions 51A, 51B when viewed from the Y direction and that is connected to the front wall 62. The cross-sectional shape of the intermediate wall 63 (the cross-sectional shape perpendicular to the direction in which the intermediate wall 63 extends) is a shape (specifically, a rectangular shape) whose longitudinal direction is in the Y direction.

[0059] 1 , the Y-direction position of the other Y-direction side surface 62b of the front wall 62 coincides with the Y-direction position of the other Y-direction side surface 61b of the side wall 61. Therefore, the other Y-direction side surfaces 61b of the pair of side walls 61 and the other Y-direction side surface 62b of the front wall 62 constitute the other Y-direction ends 61b, 62b of the protective wall 60. The other Y-direction ends 61b, 62b of the protective wall 60 are located on the other Y-direction side of the other Y-direction ends of the pair of pin-shaped connecting portions 51A, 51B. The Y-direction position of the other Y-direction side surface 63b of the intermediate wall 63 also coincides with the Y-direction position of the other Y-direction side surface 62b of the front wall 62.

[0060] 4 , one Y-direction side surface 62a of the front wall 62 is located on the other Y-direction side of one Y-direction side surfaces 61a of the pair of side walls 61. Therefore, one Y-direction side surface 62a of the front wall 62 does not constitute one Y-direction end 61a of the protective wall 60, and one Y-direction side surfaces 61a of the pair of side walls 61 constitute one Y-direction end 61a of the protective wall 60. The one Y-direction end 61a of the protective wall 60 is located on one Y-direction side of one Y-direction ends of the pair of pin-shaped connecting portions 51A, 51B.

[0061] <Operation and Effect> Next, the operation and effect of this embodiment will be described.

[0062] 1 , the speaker 10 includes a first terminal 50A and a second terminal 50B. The first terminal 50A has a first pin-shaped connecting portion 51A extending toward one side in the X direction, and the second terminal 50B has a second pin-shaped connecting portion 51B extending toward one side in the X direction. The first pin-shaped connecting portion 51A is connected to a first mating terminal 90A from one side in the Y direction, and the second pin-shaped connecting portion 51B is connected to a second mating terminal 90B from one side in the Y direction. The first pin-shaped connecting portion 51A and the second pin-shaped connecting portion 51B form a pair of pin-shaped connecting portions 51A, 51B aligned in the Z direction.

[0063] However, in a speaker 10 provided with such a pair of pin-shaped connecting portions 51A, 51B, there is a risk that the pin-shaped connecting portions 51A, 51B may come into contact with an operator's fingers or other objects, causing deformation of the terminals 50. Therefore, in this embodiment, as shown in FIG. 1 , the speaker 10 is provided with a protective wall 60 that protects the pair of pin-shaped connecting portions 51A, 51B. Therefore, the protective wall 60 protects the pin-shaped connecting portions 51A, 51B from contact with fingers and the like, thereby suppressing deformation of the terminals 50. Furthermore, in this embodiment, the protective wall 60 is provided in a direction perpendicular to the Y direction with respect to the pair of pin-shaped connecting portions 51A, 51B. Therefore, connection of a mating terminal 90 from one side in the Y direction is permitted.

[0064] As described above, according to this embodiment, it is possible to suppress deformation of the terminal 50 while ensuring the workability of connecting the mating terminal 90 .

[0065] 1 and 2, the protective wall 60 includes a side wall 61 provided on one or the other side in the Z direction of the pair of pin-shaped connection portions 51A, 51B. Therefore, the side wall 61 can prevent fingers or the like from touching the pair of pin-shaped connection portions 51A, 51B from one or the other side in the Z direction.

[0066] 4, in this embodiment, the side wall 61 hides at least a part (specifically, the entirety) of the pair of pin-shaped connection portions 51A, 51B when viewed from one side or the other side in the Z direction, so that the pair of pin-shaped connection portions 51A, 51B can be protected more effectively than in a configuration in which the side wall 61 does not hide the pair of pin-shaped connection portions 51A, 51B when viewed from the same direction.

[0067] 1 and 2, the protective wall 60 includes a front wall 62 provided on one side in the X direction of the pair of pin-shaped connections 51A, 51B. Therefore, the front wall 62 can prevent fingers or the like from touching the pair of pin-shaped connections 51A, 51B from one side in the X direction.

[0068] 3, in this embodiment, the front wall 62 hides at least a portion (specifically, the entirety) of the pair of pin-shaped connections 51A, 51B when viewed from one side in the X direction, which makes it possible to more effectively protect the pair of pin-shaped connections 51A, 51B compared to a configuration in which the front wall 62 does not hide the pair of pin-shaped connections 51A, 51B when viewed from the same direction.

[0069] 2 , the protective wall 60 has an intermediate wall 63 that is provided between the pair of pin-shaped connecting portions 51A, 51B when viewed from the Y direction and that is connected to the front wall 62. Therefore, the protective wall 60 can be reinforced by the intermediate wall 63.

[0070] 3 and 4, in this embodiment, the ends 61b and 62b of the protective wall 60 on the other side in the Y direction are located on the other side in the Y direction of the ends of the pair of pin-shaped connecting portions 51A and 51B on the other side in the Y direction, which effectively prevents fingers and the like from touching the pair of pin-shaped connecting portions 51A and 51B from the other side in the Y direction.

[0071] 4, in this embodiment, the end 61a of the protective wall 60 on one side in the Y direction is located on one side in the Y direction of the ends of the pair of pin-shaped connecting portions 51A, 51B on one side in the Y direction, which effectively prevents fingers or the like from touching the pair of pin-shaped connecting portions 51A, 51B from one side in the Y direction.

[0072] (Modification) FIG. 5 is a partially enlarged view of a speaker 110 according to a modification.

[0073] In the modified example, the protective wall 160 supports the tip portions 51A1, 51B1 (parts on one side in the X direction) of the first pin-shaped connecting portion 51A and the second pin-shaped connecting portion 51B. Specifically, the tip portions 51A1, 51B1 of the first pin-shaped connecting portion 51A and the second pin-shaped connecting portion 51B are supported in a state where they are embedded in the front wall 62 of the protective wall 160. This makes it possible to more effectively suppress deformation of the terminal 50. This is because, while the first pin-shaped connecting portion 51A and the second pin-shaped connecting portion 51B are supported in a cantilevered state in the structure shown in FIG. 2 , they are supported in a doubly supported state in the structure of the modified example.

[0074] In a modified example, the protective wall 160 is insert-molded using the first terminal 50A and the second terminal 50B as insert parts, so that the protective wall 160 supports a portion of one side in the X direction of at least one of the first pin-shaped connecting portion 51A and the second pin-shaped connecting portion 51B. Specifically, the frame 140 is insert-molded using the first terminal 50A and the second terminal 50B as insert parts.

[0075] [Supplementary Explanation] Although the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments.
