[0003] [Patent Document 1] JP 2003-224895 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional mechanisms can prevent the microphone device from rotating around the plug pin when a specific microphone device is connected to a specific electronic device, but when the microphone device is connected to various electronic devices, it is subject to restrictions due to the shape of each electronic device, and there is a problem that rotation of the microphone device cannot be prevented except in the specific electronic device.

[0005] Therefore, the present invention has been made in consideration of the above points, and aims to provide a microphone device and anti-rotation member that can prevent the microphone device from rotating and maintain the microphone device in a desired posture even when attached to various electronic devices. [Means for solving the problem]

[0006] One form of the microphone device of the present invention comprises a microphone unit having a sound collection portion, a holding member for holding the microphone unit in a predetermined orientation relative to an electronic device, the holding member having one end connected to the microphone unit and the other end provided with a connection terminal connected to the electronic device, and a rotation prevention member for preventing the holding member from rotating around the connection terminal, the rotation prevention member having an attachment portion attached to a plug body of the connection terminal, and a plate-shaped pressing member extending from the attachment portion toward the tip side of the plug pin of the connection terminal, the pressing member being configured to elastically deform by abutting against an outer surface of the electronic device when the plug pin is inserted into a socket of the electronic device, so that a part of the pressing member is pressed against the outer surface.

[0007] The rotation prevention member may be an elastic member in which the mounting portion and the pressing member are integrally formed.

[0008] A protrusion that protrudes toward the plug pin may be formed at a tip end of the pressing member.

[0009] The width of the pressing member may be wider toward the tip side of the pressing member.

[0010] The mounting portion may be a cylindrical portion attached to the plug body, and the anti-rotation member may further have a ring-shaped covering portion formed to protrude from the end of the cylindrical portion toward the tip side of the plug pin, and the covering portion may cover the periphery of the socket when the plug pin is inserted into the socket.

[0011] The plug body may be formed in an L-shape including a first portion extending in the same direction as the plug pin and a second portion protruding in a direction intersecting the first portion, and the anti-rotation member may have a raised portion formed on an upper end of the cylindrical portion, and the raised portion may have a shape such that, when the plug body with the anti-rotation member attached is viewed from the opposite side of the plug pin, when the angle between the line connecting the central axis of the plug pin and the position of the pressing member and the protruding direction of the second portion is 90 degrees, the first portion of the raised portion abuts or is close to the second portion, and when the angle is 270 degrees, the second portion of the raised portion abuts or is close to the second portion.

[0012] One form of the anti-rotation member of the present invention is a rotation prevention member attached to a connection terminal having a plug pin and a plug body to be inserted into a socket of an electronic device, and has an attachment portion attached to the plug body, and a plate-shaped pressing member extending from the attachment portion toward the side where the tip of the plug pin of the connection terminal is located when attached to the plug body, and the pressing member is formed of an elastic member and is configured to be elastically deformable in the thickness direction of the pressing member. Effect of the Invention

[0015] <First embodiment> Fig. 1 is a perspective view of a microphone device according to an embodiment of the present invention. Fig. 2 is a perspective view showing a state in which the microphone device is attached to an electronic device. Fig. 3 is a perspective view showing a microphone unit. Fig. 4 is a front view showing the microphone unit.

[0016] 1, the microphone device S100 includes a microphone unit 1, a holding member 2, and a windscreen 3. The microphone device S100 is connected to an electronic device 4 such as a digital camera.

[0017] The microphone unit 1 is held by a holding member 2, and has a microphone body 10 and a support unit 20. The microphone body 10 has a housing 11, a first sound collection section 12L, and a second sound collection section 12R.

[0018] In this example, the housing 11 has a cylindrical shape. A windscreen 3 is removably attached to the housing 11.

[0019] The first sound collection section 12L collects sounds from a first direction (e.g., the L side). The second sound collection section 12R collects sounds from a second direction (e.g., the R side). The first sound collection section 12L and the second sound collection section 12R are formed on the side surface of the housing 11, and are provided at intervals of 180 degrees from each other in the circumferential direction, for example. In other words, the first sound collection section 12L and the second sound collection section 12R are provided so that the directivity of the first sound collection section 12L and the directivity of the second sound collection section 12R are opposite to each other.

[0020] The support unit 20 is a member that supports the microphone body 10. The support unit 20 is configured to be rotatable with respect to the holding member 2. Specifically, the support unit 20 has a holder member 21 and a shock mount 25, as shown in FIG.

[0021] The holder member 21 is a member formed in a cylindrical shape. The holder member 21 has therein a mechanism for limiting the rotation angle of the microphone body 10 relative to the holding member 2 to a predetermined range. This mechanism will be described later with reference to other drawings.

[0022] The shock mount 25 is a structure for reducing the transmission of force applied to the support unit 20 to the microphone body 10. As shown in Fig. 3, the shock mount 25 has a ring member 25a and a support member 25b.

[0023] The ring member 25a is provided on the upper part of the holder member 21. The ring member 25a is, for example, circular, and has a diameter larger than the diameter of the holder member 21 and the diameter of the housing 11.

[0024] The support member 25b is a rod-shaped member provided so as to extend inward from the ring member 25a. As shown in Fig. 4, a plurality of support members 25b are provided below the ring member 25a, and a plurality of support members 25b are also provided above the ring member 25a. Since the support unit 20 holds the microphone body 10 via the shock mount 25 configured in this way, the force applied to the support unit 20 is less likely to be transmitted to the microphone body 10.

[0025] 1 and 2, the holding member 2 is a member that holds the microphone unit 1 in a predetermined orientation relative to an electronic device 4 (a digital camera as an example). In this example, the holding member 2 is a flexible pipe that is bendable and can maintain its posture in a bent state. One end of the holding member 2 is connected to the microphone unit 1. The other end of the holding member 2 is provided with a connection terminal 5 that is connected to the electronic device 4. In this example, the connection terminal 5 is a mini plug.

[0026] Fig. 5 is a cross-sectional view of the microphone unit. As shown in Fig. 5, the holding member 2 has an inner pipe 2a and a covering member 2b. The inner pipe 2a is, for example, a metallic cylindrical member. The inner pipe 2a is not a flexible member like an earphone cord, but is provided so as to be bendable. A cable 6 is passed through the inside of the inner pipe 2a. The covering member 2b is disposed outside the inner pipe 2a so as to cover the outer periphery of the inner pipe 2a.

[0027] 5, the holder member 21 has a partition wall 22. The partition wall 22 divides the internal space of the cylindrical holder member 21 into a first space S1 and a second space S2. The first space S1 is a space on the side where the holding member 2 is inserted, and the second space S2 is a space on the side closer to the microphone body 10.

[0028] A through hole 22h is formed in the center of the partition wall 22, and an end of the holding member 2 passes through this through hole 22h and is fixed in the second space S2. In this embodiment, the end of the holding member 2 is fixed by a pull-out prevention structure 50 arranged in the second space S2. The pull-out prevention structure 50 will be described later with reference to other drawings.

[0029] (Rotation mechanism of microphone unit) The microphone unit 1 is a stereo microphone, and as described above, includes the first sound collection unit 12L and the second sound collection unit 12R. The microphone device S100 is preferably attached to the electronic device 4 so that the first sound collection unit 12L faces left and the second sound collection unit 12R faces right when viewed from the photographer, for example.

[0030] However, the position of the socket 4a (see FIG. 12) for connecting the microphone device S100 varies depending on the electronic device 4. For example, the socket 4a may be provided on the right side or the left side of the electronic device 4. Also, the socket 4a may be provided on the top surface of the electronic device 4.

[0031] Therefore, in order to enable adjustment of the orientation of the microphone device S100 even if the position of the plug-in port 4a differs in this way, the microphone device S100 of this embodiment is configured to be rotatable with respect to the holding member 2 as shown in FIG.

[0032] The rotation axis CL (FIG. 2) extends in a direction parallel to the extension direction of the flexible pipe that is the holding member 2 (specifically, the extension direction of the flexible pipe at the connection portion between the holding member 2 and the microphone unit 1). In this embodiment, the rotation axis CL is an axis that coincides with the central axis of the microphone unit 1, and is located between the first sound collection part 12L and the second sound collection part 12R.

[0033] (Rotation mechanism) The rotation mechanism will be described in detail below. Fig. 6 is a perspective view of a connection between the holding member 2 and the holder member 21. Fig. 7 is a diagram showing a schematic view of an end of the holding member 2. Fig. 8 is a diagram showing a schematic view of an end of the holder member 21.

[0034] As shown in Fig. 6(a), a stopper 31 is fixed to an end of the holding member 2. The stopper 31 is fixed so as not to rotate relative to the holding member 2. As shown in Fig. 7, the stopper 31 includes a sectorial portion with a central angle of 120 degrees based on the center of the holding member 2. End faces 31a and 31b of this portion abut against the end of a rotation stopper, which will be described later.

[0035] As shown in Fig. 6(b), a rotation stopper 27 for restricting rotation of the holder member 21 is provided in the first space S1 of the holder member 21. As shown in Fig. 8, the rotation stopper 27 has an annular sector portion with a central angle of 30 degrees with respect to the center of the holder member 21. This annular sector portion has end surface 27a and end surface 27b.

[0036] Fig. 9 is a schematic diagram for explaining the rotation of the microphone unit 1. Fig. 9(b) shows a state in which the microphone unit 1 is located at the center of the movable range in the rotation direction. As an example, the microphone unit 1 rotates in a range of 90 degrees counterclockwise, as shown in Fig. 9(a), based on the state of Fig. 9(b). The microphone unit 1 also rotates in a range of 90 degrees clockwise, as shown in Fig. 9(c), based on the state of Fig. 9(b).

[0037] Thus, in this embodiment, the microphone unit 1 is provided rotatably within a range of 180 degrees with respect to the holding member 2. With such a configuration, the user can appropriately rotate the microphone unit 1 of the microphone device S100 and adjust the position of the microphone unit 1 so that the first sound collection section 12L and the second sound collection section 12R each face in a predetermined direction.

[0038] In this embodiment, the movable range of the microphone unit 1 relative to the holding member 2 is 180 degrees (in other words, the microphone unit 1 is configured to rotate 90 degrees clockwise and counterclockwise from the center of the movable range in the rotation direction), but the movable range is not limited to the above. For example, the movable range of the microphone unit 1 relative to the holding member 2 may be 240 degrees or less (120 degrees or less clockwise and counterclockwise from the center of the movable range).

[0039] The movable range may be, for example, 360 degrees, but if the movable range is too wide, there is a possibility that the cable 6 may break, so the movable range as described above is preferable as an example.

[0040] (Microphone unit retention mechanism) Fig. 10 is an exploded perspective view showing the configuration of the pull-out prevention structure 50. Fig. 11 is a cross-sectional view of the pull-out prevention structure 50. The pull-out prevention structure 50 is provided at the end of a flexible pipe that is the retaining member 2 extending from the first space S1 toward the second space S2. The pull-out prevention structure 50 has a pressing plate 51, an O-ring 52, and a washer 53.

[0041] Presser plate 51 is a circular member with a hole formed in the center, and is fixed to the end of holding member 2 as shown in Fig. 11. Washer 53 is arranged so as to contact partition wall 22. O-ring 52 is arranged in a compressed state in the axial direction of the flexible pipe between presser plate 51 and washer 53. Washer 53 is not an essential component of pull-out prevention structure 50, and may be omitted.

[0042] The retaining structure 50 prevents the holding member 2 from slipping out of the through-hole 22h of the partition wall 22, and also has the function of fixing the position of the microphone unit 1. Specifically, the compressed O-ring 52 applies a biasing force to the washer 53 in a direction that presses the washer 53 against the partition wall 22, thereby preventing the microphone unit 1 from freely rotating relative to the holding member 2. With this configuration, the position of the microphone unit 1 in the rotational direction relative to the holding member 2 is fixed.

[0043] According to the configuration of this embodiment, the anti-slip structure 50 for preventing the retaining member 2 from coming loose also serves as a means for fixing the position of the retaining member 2 in the rotational direction, thereby achieving the advantage of not complicating the structure.

[0044] (Cushioning material) A buffer member 55 is disposed inside the second space S2 as shown in Fig. 11. The buffer member 55 is a member formed in a substantially C-shape and having a circular outline as shown in Fig. 10. The buffer member 55 is, for example, a felt member having a predetermined thickness.

[0045] As described above, in this embodiment, the microphone body 10 is supported by the support unit 20 via the shock mount 25, and the microphone body 10 is movable within a predetermined movable range relative to the support unit 20. In this configuration, in this embodiment, the buffer member 55 is disposed so as to support the end of the protruding portion 10a that protrudes from the microphone body 10 toward the holder member 21.

[0046] The buffer member 55 is fixed inside the holder member 21. According to a configuration in which the buffer member 55 made of a felt material is provided in this manner, the vibration transmitted from the support unit 20 to the microphone body 10 can be attenuated more effectively than in a structure in which the protruding portion 10a is supported by a hard resin member, for example, and recording performance can be improved.

[0047] (Effect of microphone device S100) As described above, according to the microphone device S100 of this embodiment, the microphone unit 1 is rotatably arranged with respect to the holding member 2, so that the microphone unit 1 can be rotated while connected to the electronic device 4 to adjust the sound collection section to a predetermined orientation, and therefore the directivity can be set in the desired direction.

[0048] <Second embodiment> Next, an example in which the microphone device S100 is attached to an electronic device via the anti-rotation member 70 will be described with reference to Figs. 12 to 16. Fig. 12 is a perspective view showing how the microphone device S100 is attached to an electronic device via the anti-rotation member 70. Fig. 13 is a diagram showing the anti-rotation member 70. Fig. 14 is a cross-sectional view of the anti-rotation member 70. Fig. 15 is a diagram showing an example of a state of the anti-rotation member 70 when the connection terminal 5 is connected to the electronic device 4. Fig. 16 is a diagram showing another example of a state of the anti-rotation member 70 when the connection terminal 5 is connected to the electronic device 4.

[0049] One of the features of the configuration of this embodiment is that it is provided with a rotation prevention member 70. In the case of a configuration in which the plug pin 5a is inserted into the socket 4a of the electronic device 4 as exemplified in Fig. 12, a rotational force is generated by the weight of the microphone unit 1 and the holding member 2, which may cause a problem that the microphone device S100 rotates.

[0050] Therefore, in the configuration of this embodiment, a rotation prevention member 70 is provided to prevent the microphone device S100 from rotating.

[0051] As an example, the microphone device S100 of this embodiment is the same as that of the first embodiment. The microphone device S100 includes a microphone unit 1 and a holding member 2 that holds the microphone unit 1.

[0052] A connection terminal 5 is provided at an end of the holding member 2. In this example, the connection terminal 5 has a cylindrical plug body 5b and a round bar-shaped plug pin 5a protruding from the plug body 5b.

[0053] 13, anti-rotation member 70 has an attachment portion 71, a pressing member 73, and a cover portion 75. In this example, anti-rotation member 70 is a single member in which attachment portion 71, pressing member 73, and cover portion 75 are integrally formed. One example of the material for anti-rotation member 70 is an elastic member such as rubber.

[0054] The mounting portion 71 is a portion that is attached to the plug body 5b. The mounting portion 71 has a cylindrical shape. The inner diameter of the mounting portion 71 is slightly shorter than the diameter of the plug body 5b. The mounting portion 71 is attached to the plug body 5b in a state in which it is elastically deformed so as to expand slightly in the radial direction.

[0055] 13, a protruding portion 71a is formed on the upper end of the mounting portion 71. The function of the protruding portion 71a will be described later with reference to other drawings.

[0056] The pressing member 73 is formed in a substantially plate-like shape. As illustrated in Fig. 14, the pressing member 73 is formed to extend from the attachment portion 71 toward the tip side of the plug pin 5a when the anti-rotation member 70 is attached to the plug body 5b. The pressing member 73 is elastic and is provided so as to be bendable in its thickness direction.

[0057] The pressing member 73 may be formed so as to be in contact with the mounting portion 71 , but in this embodiment, it is connected to the mounting portion 71 via a connection portion 72 .

[0058] As shown in Fig. 13(b), a protrusion 73a is formed at the tip of the pressing member 73. As an example, the protrusion 73a has a flat pressing surface. As shown in Fig. 14, the protrusion 73a protrudes toward the plug pin 5a.

[0059] The width of the pressing member 73 may be constant from the base end side, which is the side closer to the connecting portion 72, toward the tip end side, but in this embodiment, the width of the pressing member 73 increases toward the tip end side of the pressing member 73 as shown in Fig. 13(d). With this configuration, the protruding portion 73a at the tip end of the pressing member 73 can be formed large.

[0060] The cover portion 75 is formed so as to protrude from the end of the mounting portion 71 toward the tip side of the plug pin 5a. The cover portion 75 has a ring-like shape with a diameter larger than that of the mounting portion 71. Specifically, the cover portion 75 is formed in a circular ring shape. The tip portion of the cover portion 75 is an inclined tapered surface 75a. Specifically, the tapered surface 75a is a truncated cone-shaped surface whose inner diameter becomes larger toward the tip side.

[0061] Since the tip of the covering portion 75 is formed in such a shape, the tip of the covering portion 75 is easily deformed. As a result, when the connection terminal 5 is connected to the electronic device 4, the covering portion 75 can follow the shape of the outer surface of the electronic device 4 and satisfactorily cover the periphery of the socket 4a.

[0062] (Example of use of anti-rotation member 70) Fig. 15 is a diagram showing an example of attachment of the rotation prevention member 70 to the electronic device 4. Specifically, Fig. 15 shows a state in which the plug pin 5a is inserted into the socket 4a, and the outer surface 4S corresponds to a side surface of the electronic device 4. When the plug pin 5a is inserted into the socket 4a as shown in Fig. 15, the pressing member 73 comes into contact with the outer surface 4S of the electronic device 4, and is elastically deformed so as to be bent as a whole. As a result, a protrusion 73a, which is a part of the pressing member 73, is pressed against the outer surface 4S.

[0063] In this manner, a part of the pressing member 73 is pressed against the outer surface 4S, making it difficult for the connection terminal 5 to rotate around the plug pin 5a. Therefore, according to the configuration of this embodiment, the microphone device S100 can be maintained in a predetermined orientation.

[0064] 15, the cover portion 75 covers the periphery of the socket 4a. This configuration has the effect of preventing liquids such as rain, dust, and the like from entering the socket 4a.

[0065] 16 is a diagram showing another example of how the anti-rotation member 70 is attached to the electronic device 4. The outer surface 4S in FIG.

[0066] In the state shown in Fig. 16, the tip of the pressing member 73 is pressed against the outer surface 4F that intersects with the outer surface 4S on which the insertion port 4a is provided, rather than against the outer surface 4S. The pressing member 73 is not bent as much as in the state shown in Fig. 15, but is elastically deformed so as to bend gently overall. The protruding portion 73a is pressed against the outer surface 4F.

[0067] In this way, the pressing member 73 can be attached to the electronic device 4 in the orientation shown in Fig. 16 in addition to the orientation shown in Fig. 15. The rotation prevention member 70 of this embodiment is provided so as to be elastically deformable to the extent that the pressing member 73 bends, and therefore can be attached to the electronic device 4 in various orientations. This means that the rotation prevention member 70 can be used for a plurality of electronic devices having different positions of the plug-in port 4a.

[0068] (Regarding the raised portion 71a) Next, the function of the raised portion 71a will be described with reference to Figures 17 and 18. Figure 17 is a perspective view showing the anti-rotation member 70 and the connection terminal 5. Figure 18 is a view showing the plug body 5b to which the anti-rotation member 70 is attached, viewed from the opposite side of the plug pin 5a.

[0069] The anti-rotation member 70 may be configured to be attached in any orientation (meaning the orientation in the circumferential direction) to the plug body 5b of the connection terminal 5, but in this embodiment, a raised portion 71a is provided as a means for determining the attachment orientation of the anti-rotation member 70 to the connection terminal 5.

[0070] 17, the plug body 5b of the connection terminal 5 is L-shaped. Specifically, the plug body 5b includes a first portion 5b-1 extending in the same direction as the plug pin 5a, and a second portion 5b-2 protruding in a direction intersecting the first portion 5b-1.

[0071] The raised portion 71a formed on the upper end of the cylindrical mounting portion 71 has a shape such that when the anti-rotation member 70 is attached to the plug body 5b, the upper end of the raised portion 71a is higher than the lower end of the second portion 5b-2.

[0072] Because such a protrusion 71a is formed, as shown in Figure 18(a), the first portion 71b of the protrusion 71a abuts against the second portion 5b-2 when the angle between the line L1 connecting the central axis of the plug pin and the position of the pressing member 73 and the line L2 in the protruding direction of the second portion 5b-2 is 90 degrees.

[0073] On the other hand, as shown in FIG. 18(b), when the angle between the line L1 and the line L2 is 270 degrees, the second portion 71c of the raised portion 71a abuts against the second portion 5b-2.

[0074] According to the above-described configuration, the user can attach the anti-rotation member 70 to the plug body 5b, for example, in an orientation in which the pressing member 73 is at an angle of 90 degrees or 270 degrees with respect to the line L2.

[0075] In the above example, the raised portion 71a abuts against the second portion 5b-2 at 90 degrees and 270 degrees, respectively. However, the abutment is not necessarily required, and the raised portion 71a may be configured to be close to the second portion 5b-2.

[0076] (Advantages of the Configuration of the Second Embodiment) As described above, according to the configuration of this embodiment, the microphone device S100 is attached to the electronic device 4 via the anti-rotation member 70, so that it is possible to prevent the microphone device S100 from rotating around the plug pin 5a. In this way, the function of the anti-rotation member 70 prevents the microphone device S100 from rotating, so that it is possible to maintain the microphone device S100 in a desired position.

[0077] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by distributing or integrating functionally or physically in any unit. In addition, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention.
