Description

TECHNICAL FIELD

[0001] Aspects of the embodiments relate to a microphone device used with an attachment to a camera device. BACKGROUND

[0002] External microphones are known as external accessories of camera devices such as digital cameras. The external microphone is used in an attached state in which the external microphone is attached to an accessory socket of the camera device. When a moving image is captured in the attached state of the external microphone, vibration caused by, for example, driving of a lens of the camera device, operation vibration caused by an operation on the camera device, or the like can be transmitted to the external microphone. The external microphone can collect this vibration as noise. For example, Japanese Patent No. 6164415 discloses a microphone device having a damper that is able to absorb vibration generated in a motor for driving a lens of a camera device. The damper of the microphone device disclosed in this publication document includes an inner ring, an outer ring arranged on the outer side of the inner ring, and a plurality of ribs connecting the inner ring and the outer ring. Each rib extends linearly.

[0003] However, the damper of the microphone device disclosed in the above publication document impairs the vibration absorption characteristics of vibration in a direction parallel to the extension direction of the ribs, that is, impairs the vibration reduction performance. In the microphone device described in the above publication document, when the extension direction of the ribs coincides with a direction perpendicular to a diaphragm of a microphone element, the damper can not be sufficient to reduce vibration (noise). The microphone element is configured in various directions depending on, for example, a system type such as a stereo system or a monaural system, directivity setting as an acoustic performance, or the like. Therefore, the damper needs to appropriately configure the ribs in various configuration directions of the microphone element, and thus has poor versatility. SUMMARY

[0004] The present disclosure provides a microphone device that is able to reduce vibration from a camera device regardless of a configuration direction of a microphone element with respect to the camera device.

[0005] Accordingly, one aspect of the embodiment provides a microphone device used with a camera device attached. The microphone device includes a microphone main body configured to include a microphone element capable of collecting sound, an attachment portion configured to be attached to the camera device, and a connection portion configured to connect the microphone main body and the attachment portion. The connection portion includes a shock absorber that mitigates transmission of vibration from the camera device to the microphone main body, and a cover that houses the shock absorber. The shock absorber includes a first fixing portion fixed to the attachment portion, a second fixing portion fixed to the cover, and an elastic coupling portion that couples the first fixing portion and the second fixing portion. Each coupling portion has a curved portion that curves at a middle position between the first fixing portion and each second fixing portion. And the curved portion has a first surface and a second surface that face each other at an inner side of the curved portion, are capable of approaching and distancing from each other, and are separated from each other in a natural state where no external force is applied.

[0019] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, the configurations described in the following embodiments are merely examples, and the scope of the present disclosure is not limited by the configurations described in the embodiments. For example, each unit constituting the present disclosure can be replaced with any configuration capable of exhibiting the same function. Furthermore, any constituent can be added. Any two or more configurations (features) of the embodiments can be combined. Figures 1A to 7 A first embodiment will be described. Figure 1A and Figure 1B is a perspective view showing a positional relationship between a camera device and a microphone device in a detached state. Figure 1A is a front perspective view. Figure 1B is a rear perspective view. Hereinafter, for the sake of convenience of description, Figure 1A the upper side in is referred to as "up (or above)", and the lower side is referred to as "down (or below)" (the same applies to Figure 1B , Figure 2A , Figure 3 and Figures 5A to 11 ). As shown in Figure 1A , a digital camera 100 as a camera device includes a camera body 101, an accessory socket 110, a mode switching switch 160, a shutter button 161, and a lens unit 120. As shown in Figure 1B , the digital camera 100 includes a display unit 128, an operation unit 170, and a power switch 172. A microphone device (hereinafter simply referred to as "microphone") 200 is detachably attached to the digital camera 100. The microphone 200 is used in an attached state in which the microphone 200 is attached to the digital camera 100. The microphone 200 includes an attachment leg (attachment portion) 210, a connection portion (body portion) 230, and a microphone body 250.

[0020] The camera body 101 has an image sensor (not shown) constituted by a CCD, a CMOS, or the like. Figure 1A and Figure 1BThe accessory socket 110 is arranged near the center of the upper surface of the camera body 101. An external accessory such as the microphone 200 is detachably connected (attached) to the accessory socket 110. The accessory socket 110 is provided with an electric contact (not shown) that is electrically connected to an electric contact 210a (not shown) provided in the attachment leg 210 of the microphone 200. Figure 3 The mode switching switch 160 is arranged at the end of the upper surface of the camera body 101. The mode switching switch 160 is used to change the mode among various modes including the moving image capturing mode. The shutter button 161 is arranged at the end of the upper surface of the camera body 101 on the side opposite to the mode switching switch 160. The shutter button 161 is used to issue a photographing instruction. The lens unit 120 is detachably attached to the front surface of the camera body 101. The lens device 120 includes a lens barrel 121 that houses a lens group (not shown) for zooming, focusing, image stabilization, and the like. The lens barrel 121 also houses a motor for driving the lens group. The display unit 128, the operation unit 170, and the power switch 172 are arranged on the back of the camera body 101. The display unit 128 displays images and various information. The operation unit 170 is composed of operation members such as various switches, buttons, and dials. The operation unit 170 receives various operations from the user who uses the digital camera 100, including a moving image capturing start operation. The power switch 172 is used to switch the power of the camera body 101 between ON and OFF.

[0021] Figure 2A and Figure 2B is an exploded perspective view showing the microphone. Figure 2A is a front perspective view. Figure 2B is a rear perspective view. Figure 3 is a sectional view taken along the line A-A in Figure 1A As described above, the microphone 200 includes the attachment leg 210, the body portion 230, and the microphone body 250, which are configured in this order from the bottom. The microphone body 250 is capable of collecting external sound. The attachment leg 210 is detachably attached to the accessory socket 110 of the digital camera 100. The body portion 230 connects the microphone body 250 and the attachment leg 210. As Figure 2A , Figure 2B and Figure 3As shown, the microphone main body 250 includes a microphone element 251, a control board 253, and a cover 252. The microphone element 251 can collect sound and output the sound as a sound signal. Although a single microphone element 251 is configured in the present embodiment, two or more microphone elements can be configured. The microphone element 251 is electrically connected to the control board 253. The sound signal output from the microphone element 251 is subjected to predetermined processing such as sound synthesis processing in the control board 253, and then transmitted as an electric signal to the digital camera 100 via the flexible board 227 of the attachment leg 210. The cover 252 is a cylindrical member in which the microphone element 251 and the control board 253 are housed. The attachment leg 210 is inserted into the accessory socket 110 of the digital camera 100 in a predetermined direction (a direction from the back to the front of the digital camera 100 in the present embodiment). As a result, the microphone 200 is attached to the digital camera 100.

[0022] As shown in Figure 2A , Figure 2B and Figure 3 , the attachment leg 210 includes an attachment leg main body 209 and a flexible board 227. The attachment leg main body 209 has a disc shape. A main body connecting portion 231 projecting upward in a cylindrical shape is formed at the center of the attachment leg main body 209. The main body connecting portion 231 is connected to the main body portion 230. The attachment leg main body 209 supports the flexible board 227. The flexible board 227 is electrically connected to the control board 253 of the microphone main body 250.

[0023] As shown in Figure 2A , Figure 2B and Figure 3 , the main body portion 230 includes a damper (shock absorber) 211, an intermediate member 232, an intermediate housing (cover) 233, and a top housing 238. The damper 211 is a shock absorber that alleviates the transmission of vibration from the digital camera 100 to the microphone main body 250 when vibration occurs in the digital camera 100, that is, an absorber that absorbs vibration from the digital camera 100. The vibration generated in the digital camera 100 includes, for example, vibration generated in a motor for driving a lens group. Although the vibration can be collected as noise by the microphone main body 250, the damper 211 can prevent sound collection. The damper 211 is made of an elastic material. Such a material is not particularly limited, and various rubber materials (such as fluororubber), in addition to gels and porous bodies, can be used, for example.

[0024] The damper 211 includes a first fixing portion 212, a second fixing portion 213, and an arm portion 214. The first fixing portion 212 is fixed to the attachment leg 210. The first fixing portion 212 has a cylindrical shape (annular shape). An intermediate member 232 having a cylindrical shape is inserted, that is, fitted, in the first fixing portion 212. The intermediate member 232 has a lower portion of a body connecting portion 231 fixed to the attachment leg 210 with a screw 290. A flange 239 having an enlarged outer diameter is provided at an upper end portion and a lower end portion of the intermediate member 232, respectively. This prevents the intermediate member 232 from coming off the first fixing portion 212. The first fixing portion 212 is fixed to the attachment leg 210 via the intermediate member 232.

[0025] On the outer peripheral side of the first fixing portion 212, a plurality of second fixing portions 213 are arranged at equal intervals along the circumferential direction. Although the number of the second fixing portions 213 is eight in the present embodiment, it is not limited thereto. For example, the number can be one to seven, or nine or more. Each of the second fixing portions 213 is fixed to an intermediate housing 233. Each of the second fixing portions 213 has a cylindrical shape (cylindrical shape) and is arranged so that a central axis thereof is parallel to a central axis of the first fixing portion 212. The entire length (length in the direction of the central axis) of each of the second fixing portions 213 is equal to the entire length of the first fixing portion 212. The diameter of each of the second fixing portions 213 is smaller than the inner diameter and the outer diameter of the first fixing portion 212.

[0026] The arm portion 214 is a coupling portion that couples the first fixing portion 212 and each of the second fixing portions 213. The height (length in the direction of the central axis) of the arm portion 214 is equal to the entire length of the first fixing portion 212. The damper 211 is made of a material having elasticity as described above, and each of the arm portions 214 mainly functions to reduce vibration from the digital camera 100 to the microphone main body 250. Note that, although depending on the arrangement position of the second fixing portion 213, the arm portion 214 is preferably arranged along at least one of the optical axis direction of the digital camera 100 and the width direction of the digital camera 100. This makes it possible to at least exhibit the vibration reduction function of the arm portion 214. The damper 211 can be entirely made of an elastic material, but it is sufficient that at least the arm portion 214 is made of an elastic material. Although the damper 211 is formed by integrally forming the first fixing portion 212, the second fixing portion 213, and the arm portion 214 in the present embodiment, it is not limited thereto. For example, the damper 211 can be configured so that the first fixing portion 212, the second fixing portion 213, and the arm portion 214 are formed as separate bodies, and these separate bodies are connected to each other.

[0027] The intermediate housing 233 has a tubular shape and accommodates the damper 211 therein. The intermediate housing 233 has an opening 234 at its bottom portion through which the body connecting portion 231 of the attachment leg 210 is inserted to prevent interference with the body connecting portion 231. Further, a damper connecting portion (cap side fixing portion) 235 for fixing the second fixing portion 213 is provided on the inner peripheral portion of the intermediate housing 233. The damper connecting portion 235 has a cylindrical shape into which the second fixing portion 213 can be inserted in a loose fit state, i.e., with play (clearance) (see Figure 4 ) respectively. As a result, the second fixing portion 213 is fixed to the intermediate housing 233. Further, the inner peripheral portion of the intermediate housing 233 is provided with a claw 236 and a hole 237 at positions facing each other.

[0028] The top housing 238 covers the intermediate housing 233 from above. A plurality of ribs 240 protruding downward are formed on the lower surface of the top housing 238. The ribs 240 prevent the second fixing portion 213 of the damper 211 from coming off upward from the damper connecting portion 235 of the intermediate housing 233. Further, a recess 241 engaging with the claw 236 of the intermediate housing 233 and a screw hole 242 into which a screw 293 inserted through the hole 237 of the intermediate housing 233 is screwed are provided on the lower surface of the top housing 238. The top housing 238 has a plurality of through holes 243 penetrating in the up-down direction. A screw 291 threadedly connected with the microphone body 250 is inserted into each of the through holes 243. Thus, the top housing 238 is fixed to the microphone body 250. The microphone body 250 and the attachment leg 210 are connected via the body portion 230 having such a configuration.

[0029] Figure 4 is a cross-sectional view taken along the line B-B in Figure 1B . Since the configurations of the respective arm portions 214 are the same, the configuration of one arm portion 214 will be described as a representative example. As shown in Figure 4As shown, the arm portion 214 has a bent portion 244a bent at a middle position between the first fixed portion 212 and the second fixed portion 213. The bent portion 244a has a first inner surface (first surface) 245 and a second inner surface (second surface) 246 facing each other on the inner side of the bent portion. The first inner surface 245 is located on the side of the first fixed portion 212, and the second inner surface 246 is located on the side of the second fixed portion 213. The first inner surface 245 and the second inner surface 246 can approach and depart from each other according to the use state of the digital camera 100, that is, the posture (direction) of the microphone 200. The first inner surface 245 and the second inner surface 246 are spaced apart from each other in a natural state where no external force is applied, and a gap 244 is formed between the first inner surface 245 and the second inner surface 246. Note that, in the natural state, the portions of the arm portion 214 on both sides across the bent portion 244a are formed as straight lines parallel to each other. Furthermore, although the arm portions 214 adjacent to each other among the plurality of arm portions 214 differ in the direction of bending, that is, differ in the direction of bending convexity in the present embodiment, they are not limited thereto and can be the same in the direction of bending. When vibration from the digital camera 100 is transmitted to the attachment leg 210 of the microphone 200 in a direction parallel to the extension direction of the arm portion 214, the bent portion 244a having such a configuration can release the vibration through the gap 244. This prevents an increase in rigidity, that is, a reduction in the damping effect due to strutting of the arm portion 214. Therefore, regardless of the arrangement direction of the microphone 200 (microphone element 251) with respect to the digital camera 100, it is possible to reduce the vibration from the digital camera 100.

[0030] As described above, the damper 211 has elasticity. Therefore, depending on the use state of the digital camera 100, the body portion 230 of the microphone 200 attached to the digital camera 100 and the microphone body 250 can be inclined with respect to the accessory socket 110. This will be described with reference to Figure 5A and Figure 5B . Figure 5A and Figure 5B are perspective views showing the damper and the intermediate member. Figure 5A is a perspective view in a natural state. Figure 5B is a perspective view in a state where inclination occurs. In Figure 5A the state shown, a gap 244 is formed between the first inner surface 245 and the second inner surface 246 of each arm portion 214 of the damper 211. As the generated inclination increases, the first inner surface 245 and the second inner surface 246 approach each other from the upper end side or the lower end side. Finally, the first inner surface 245 and the second inner surface 246 come into contact with each other, as Figure 5BIn this state, the inclination limit of the main body 230 and the microphone main body 250 with respect to the accessory socket 110 is regulated, that is, further inclination is limited. This prevents the main body 230 and the microphone main body 250 from being excessively inclined with respect to the accessory socket 110. The interval D244a (see FIG. 10) of the interval 244 is preferably set as follows. The interval D244a is set so that the first inner surface 245 and the second inner surface 246 come into contact with each other before the attachment leg 210 and the main body 230 or the microphone main body 250 come into direct contact with each other when the main body 230 and the microphone main body 250 are inclined. Figure 4 ) is preferably set as follows. The interval D244a is set so that the first inner surface 245 and the second inner surface 246 come into contact with each other before the attachment leg 210 and the main body 230 or the microphone main body 250 come into direct contact with each other when the main body 230 and the microphone main body 250 are inclined.

[0031] Further, when an image is captured with the digital camera 100 to which the microphone 200 is attached, the subject can move relatively greatly or the user can ride in a vehicle. In addition, when the digital camera 100 to which the microphone 200 is attached is mounted on a vehicle, something can come into contact with or collide with the microphone 200 unintentionally, which generates relatively large inertia or impact, such as inclination of the damper 211. In this case, when the attachment leg 210 of the microphone 200 comes into contact with the main body 230 or the microphone main body 250, the damping effect of the damper 211 can not be sufficiently exhibited. As a result, vibration can be directly transmitted from the contact portion between the attachment leg 210 and the main body 230 or the microphone main body 250 to the microphone main body 250. However, as described above, since the microphone 200 is designed so that the first inner surface 245 and the second inner surface 246 come into contact with each other, vibration can be prevented from being directly transmitted from the contact portion to the microphone main body 250. In a normal imaging state in which relatively large inertia or impact that inclines the damper 211 is not applied, it is preferable that the first inner surface 245 and the second inner surface 246 of the damper 211 are sufficiently separated from each other so that the damping effect can be exhibited to the maximum.

[0032] Figure 6 is a perspective view showing a first modification example of the damper applicable to the first embodiment. As Figure 6As shown, each arm portion 214 has a curved portion 244a formed on the side of the first fixed portion 212 and a curved portion 244b formed on the side of the second fixed portion 213. The curved portion 244a and the curved portion 244b are curved and convex in the same direction. The curved portion 244a has a first inner surface 245a and a second inner surface 246a. The curved portion 244b has a first inner surface 245b and a second inner surface 246b. Furthermore, the interval D244a between the first inner surface 245a and the second inner surface 246a of the curved portion 244a in the natural state is preferably different from the interval D244b between the first inner surface 245b and the second inner surface 246b of the curved portion 244b in the natural state. Specifically, the interval D244a is preferably longer than the interval D244b. When tilting occurs, due to the size correlation between the intervals, the first inner surface 245b and the second inner surface 246b of the curved portion 244b first come into contact with each other, and then, when the tilting increases, the first inner surface 245a and the second inner surface 246a of the curved portion 244a come into contact with each other. This makes it possible to stepwise limit the tilting ability of the damper 211. Although the number of curved portions formed in the present modification example is two, it is not limited thereto. For example, the number can be three or more.

[0033] Figure 7 is a perspective view showing a second modification example of the damper applicable to the first embodiment. As shown, Figure 7 the first inner surface 245 (one surface) among the first inner surface 245 and the second inner surface 246 is provided with a protrusion 247 protruding toward the second inner surface 246 (the other surface). The protrusion 247 is capable of approaching and distancing from the second inner surface 246. Therefore, as the damper 211 tilts, the protrusion 247 comes into contact with the second inner surface 246. This contact can reduce the contact area compared to the case where the protrusion 247 is omitted, and thus contributes to the mitigation of impact at the time of contact. Note that the protrusion 247 is provided on the first inner surface 245, but is not limited thereto, and can be provided on the second inner surface 246, or can be provided on both the first inner surface 245 and the second inner surface 246.

[0034] Hereinafter, the second embodiment will be described with reference to Figure 8 and Figure 9 The second embodiment will be described. Differences from the above-described embodiments will be mainly described, and the description of the same matters will be omitted. Figure 8 and Figure 9 are perspective views showing the damper in the second embodiment, respectively. One of the configurations for improving the damping effect of the damper 211 of the first embodiment is to lower the rigidity of the damper 211. As the configuration for lowering the rigidity of the damper 211, Figure 8The shown damper 211 is designed so that the height of the arm portion 214 is smaller than the entire length of the first fixed portion 212. This reduces the rigidity of the damper 211, thereby improving the damping effect. Due to the reduction in rigidity, Figure 8 The shown damper 211 tends to be more apt to tilt. In this case, since a gap for preventing contact between the attachment leg 210 and the main body portion 230 or the microphone main body 250 is to be ensured, there is a problem that the microphone 200 can be upsized. Further, since the damper 211 is apt to tilt, the microphone 200 swings back and forth and right and left, for example, when a moving image is shot while walking on one side, and there is a problem that stable sound collection is hindered.

[0035] As Figure 9 shown, the damper 211 includes a first arm portion 248 and a second arm portion 249 as the arm portion of each of the eight second fixed portions 213. The first arm portion 248 and the second arm portion 249 are arranged in the up-down direction (along the central axis direction of the first fixed portion 212). The first arm portion 248 connects the upper end portion of the first fixed portion 212 and the upper end portion of the second fixed portion 213. The second arm portion 249 connects the lower end portion of the first fixed portion 212 and the lower end portion of the second fixed portion 213. The first arm portion 248 and the second arm portion 249 are spaced apart from each other in the up-down direction, and a gap 270 is formed between the first arm portion 248 and the second arm portion 249. The volume of the portion connecting the first fixed portion 212 and the second fixed portion 213 is reduced due to the gap 270, and the rigidity against shear deformation is reduced. Further, the sectional secondary moment around the central axis of the damper 211 or the sectional secondary moment around the axis (z-axis) along the width direction of the digital camera 100, which surrounds the optical axis (x-axis) of the digital camera 100, is represented by the following equation (1).

[0036]

[0037] I x 、 z : sectional secondary moment around the x-axis or z-axis

[0038] h: height of the arm portion 214 or the arm portions 248 and 249

[0039] b: thickness of the arm portion 214 or the arm portions 248 and 249

[0040] As is clear from equation (1), the longer the distance from the axis to the section in the height direction, the larger the sectional secondary moment. Therefore, Figure 9 The shown damper 211 reduces the rigidity of the damper 211 in the translation direction to improve the damping effect, and the sectional secondary moment around the x-axis or z-axis is higher than Figure 8The cross-sectional second moment of the damper 211 shown is indicated. As a result, Figure 9 The damper 211 shown can reduce the inclination more than Figure 8 The damper 211 shown can reduce the inclination more than

[0041] Hereinafter, the third embodiment will be described with reference to Figure 10A and Figure 10B The third embodiment will be described. Differences from the above-described embodiments will be mainly described, and the description of the same matters will be omitted. Figure 10A and Figure 10B are perspective views and cross-sectional views showing a damper in the third embodiment. Figure 10A is a perspective view. Figure 10B is a cross-sectional view taken along the line C-C in Figure 10A As shown in Figure 10A , the damper 211 includes a plate-shaped portion 272 provided between a pair of adjacent ones of the eight second fixing portions 213. The damper 211 includes a protrusion 271 provided on the outer periphery of the first fixing portion 212 and protruding toward the plate-shaped portion 272. The plate-shaped portion 272 and the protrusion 271 can approach and depart from each other. The plate-shaped portion 272 and the protrusion 271 can limit the inclination limit of the main body portion 230 and the microphone main body 250 with respect to the accessory socket 110 in a state where the plate-shaped portion 272 and the protrusion 271 contact each other. This prevents the main body portion 230 and the microphone main body 250 from excessively inclining with respect to the accessory socket 110. The distance D273 (see Figure 10B ) between the plate-shaped portion 272 and the protrusion 271 is preferably set in the same manner as the distance D244a.

[0042] Figure 11 is a perspective view showing a modification example of the damper applicable to the first embodiment, the second embodiment, and the third embodiment.
