Description

  The present invention relates to an electronic device that houses a speaker used in a sound reproducing device, and an automobile and a house including the electronic device.

  In recent years, in order to further improve the realism of a two-channel stereo system in sound reproduction, various methods have been adopted, such as adopting a so-called surround system, or changing the direction of the speaker or the installation position directly by the user's hand. Yes.

  Among these methods, the technique of directly changing the direction of the speaker with the user's hand has an advantage that the visibility of the user's sound can be improved by matching with the user. As a document disclosing the technology, for example, Patent Document 1 includes a housing that includes a housing with a built-in speaker and a grill provided on the front opening side, and the grill is protruded from a wall or the like and is installed in the wall. A body assembly and a mounting mechanism for rotating and mounting the speaker to the housing assembly at a desired angular position, and the mounting mechanism can be operated from the grill side protruding from the wall. The technique of the speaker apparatus currently used is disclosed. According to this configuration, the speaker unit can be directly rotated by a user's hand and fixed at a desired angle. However, the technique described in this document has a relatively poor operability because the speaker unit is directly rotated by the user's hand.

  Further, for example, in Patent Document 2, a speaker unit is attached to a rotation chamber, a rotation shaft provided in the rotation chamber is supported by a bearing provided in a fixed chamber, and provided on the outer periphery of the rotation chamber. A technique is disclosed in which a circular arc gear is driven by a motor via another circular gear.

  However, with the techniques described in Patent Document 2 and Patent Document 1, the angle of the speaker can be changed only in a linear direction, which is the vertical direction or the horizontal direction, and the direction of the speaker is changed appropriately and arbitrarily. I couldn't.

  Further, for example, Patent Document 3 discloses a rotation reference plane forming unit that forms a rotation reference plane, a rotation plane forming unit that forms a rotation plane that can rotate along the rotation reference plane, and a tilt at a predetermined angle with respect to the rotation reference plane. Thus, there is disclosed a technique that includes a speaker attached to the rotating surface forming means, and the orientation of the reference axis of the speaker is variable by the rotation of the rotating surface forming means.

  However, the orientation of the reference axis of the speaker can only be changed by the rotation of the rotating surface forming means, and the orientation of the speaker cannot be changed appropriately and arbitrarily.

It is a perspective view which shows that the some elastic member is arrange | positioned at the surface at the back side of a cylindrical part.

  Hereinafter, an embodiment of the present invention will be described.

  An electronic apparatus according to an embodiment of the present invention includes a speaker unit, a housing, and a rotating device. The speaker unit is supported by the housing, and the rotating device rotates in a direction that intersects the axis of the housing. A first rotating device that rotates the speaker unit with respect to the housing as a shaft, and a second rotating device that rotates the speaker unit with respect to the housing with the shaft of the housing as a rotating shaft are provided. With such an electronic device, the direction of the speaker unit can be arbitrarily changed.

  The housing includes a first housing and a second housing, the speaker unit is supported by the second housing via the first housing, and the first rotating device is a speaker. The unit may be rotated with respect to the first housing, and the second rotating device may rotate the speaker unit and the first housing with respect to the second housing.

  The first housing has a shape for housing the speaker unit, the second housing has a shape for housing the first housing, and the first rotating device and the second rotating device are the first. It may be attached to the case.

  The second rotating device includes a driving device (a motor to be described later), a rotating member to which the rotation of the driving device is transmitted, and a rotated member, and the rotated member is provided in the second casing. It doesn't matter. Since the electronic device includes the rotated member, the rotational force of the second rotating device can be transmitted to the second casing.

  Further, the rotated member may be disposed in the central portion of the second casing. Since the rotational force of the second rotating device can be made relatively small, power consumption based on the second rotating device can be reduced, and an increase in size based on the second rotating device can be suppressed.

  An elastic member is attached to one of the first housing and the second housing, and the first housing may contact the second housing via the elastic member. When the first casing is rotated by the second rotating device, a gap may be formed between the second casing and the first casing. In this case, abnormal noise may occur due to contact between the first housing and the second housing. Further, vibration generated when the speaker unit is rotated or when the speaker unit is driven propagates to the entire electronic device, and the first housing and the second housing come into contact with each other to generate abnormal noise. There is a case. However, the first casing is brought into contact with the second casing via the elastic member, so that an elastic force is applied to one of the first casing and the second casing toward the other (Appendix). And the generation of abnormal noise (rattle) can be suppressed.

  The side surface of the speaker unit facing the first housing includes a contact portion that contacts the first housing, the first housing includes a contacted portion (a concave portion described later), and the speaker unit includes the first housing. You may move along the contacted part of the body.

  One of the contact part and the contacted part is a convex part and the other is a concave part, and the contact part and the contacted part may extend in the rotation direction of the first rotating device.

  The speaker unit includes a side surface facing the first housing side, the contact portion is disposed on the side surface of the speaker unit on the first housing side, and between the center portion and the outer peripheral portion of the side surface of the speaker unit. It may be arranged.

  The contacted part becomes a path when the speaker unit rotates, and the speaker unit can be rotated along a desired path by sliding while the contact part is in contact with the contacted part.

  In addition, the contact portion and the contacted portion extend in the rotation direction of the first rotating device, thereby reducing the thickness of the first housing in the axial direction or making the electronic device compact. it can. For this reason, for example, when installing the electronic device of the present invention on the front of a car, the ceiling of a house, etc., the space for the electronic device can be reduced, so a space for placing other electronic devices etc. is secured. can do.

  The contact portion of the speaker unit may include an opening, and a member (a bar-like member described later) fixed to the first housing may pass through the opening of the contact portion.

  Moreover, the contact part of the speaker unit is provided with two or more, and the member fixed to the 1st housing | casing may be a rod-shaped member. Since the member fixed to the first casing passes through the opening of the contact portion, there is no need to provide a separate shaft, and a desired axis is used as the rotation axis of the speaker unit, or the electronic device is downsized. Or the first housing and the second housing can be assembled separately, or the speaker unit can be removed and replaced when the speaker unit fails.

  A plurality of contact portions are disposed on a side surface of the speaker unit facing the first housing, a plurality of contacted portions are disposed on the first housing, and a member fixed to the first housing is provided. You may pass through the opening part of a some contact part.

  When the speaker unit is rotated by the first rotating device, a gap is generated between the rotating member of the first rotating device and the rotated member of the speaker unit, and the rotational force of the driving device is sufficiently applied to the rotated member. Can be prevented from being transmitted. Specifically, when the rotating member is a gear and the rotated member has a plurality of teeth corresponding to the gear, it is possible to prevent tooth skipping.

  The member fixed to the first housing may be arranged in the vicinity of the end on the outer peripheral side of the speaker unit among the two ends of the opening of the contact portion.

  The member fixed to the first casing is arranged in the vicinity of the end on the outer peripheral side of the speaker unit among the two ends of the opening of the contact section, thereby fixing to the first casing. The electronic device can be downsized as compared with the case where the member is disposed near the center of the speaker unit. Further, when rotating the speaker unit, the position of the member fixed to the first housing with respect to the opening can be changed between one end and the other end of the opening of the contact portion. . In other words, the range in which the position of the member fixed to the first housing in the opening can be changed can be the range from one end of the opening of the contact portion to the other end. For this reason, the speaker unit can be rotated in a wide range.

  In addition, the length of the opening or the length of the contact portion can be made relatively small.

  The speaker unit is supported by the first housing via the first rotating member, the first rotating member is supported by the support portion of the first housing, and the rotation shaft of the first rotating member. May intersect with the axis of the first housing. When the speaker unit is rotated by the first rotating device while being in contact with the first rotating member, the speaker unit can be smoothly rotated while relatively reducing the load applied to the first rotating device.

  The second rotating member may be supported by the first casing, and the speaker unit may be supported by the first casing via the second rotating member.

  Since the speaker unit is supported by the first housing via the second rotating member while being in contact with the second rotating member, the second rotating device is used when the speaker unit is rotated by the second rotating device. The speaker unit can be smoothly rotated while the load applied to is relatively small.

  The rotation axis of the speaker unit by the first rotating device may intersect the axis of the speaker unit.

  You may provide the detection part which detects the position of a speaker unit. The detection unit may include a sensor. The first housing may include a second contact portion that contacts a side surface of the speaker unit facing the first housing.

  When the speaker unit is rotated by the first rotating device, the side surface of the speaker unit (the back surface to be described later) facing the first housing and the second contact portion come into contact with each other, so that the second contact portion becomes Its position changes. The sensor can detect the position of the speaker unit by detecting the change in the position.

  A speaker unit may be detachable from the first housing. If the speaker unit is detachable, it is easy to remove and replace the speaker unit when the speaker unit fails.

  The second housing may include a lid portion, and the lid portion may be disposed at a position facing the first housing. By including the lid, it is possible to prevent dust / dust from entering the space between the speaker unit and the first housing or the space between the first housing and the second housing. In addition, it is possible to prevent external force from acting on the front surface of the speaker unit and intrusion of dust / dust into the speaker unit. Moreover, it can suppress that the sound wave radiated | emitted from the front side of a speaker unit, and the sound wave which leaks from the back side interfere. In the present invention, the “lid” is merely a part of the “second casing”, and various members that can be arranged in the “second casing” as well as the “lid” are arranged. Can be done.

  The lid portion may include a surface inclined from the outer peripheral portion of the second housing toward the bottom portion of the speaker unit. By providing the surface on which the lid portion is inclined, it is possible to prevent sound waves emitted from the speaker unit from being blocked by the lid portion when the speaker unit is rotated by the first rotating device.

  The speaker unit and the first housing may be connected by an elastic member. Further, the elastic member may be formed of a member that can be expanded and contracted. When the speaker unit is rotated by the first rotating device, a gap is generated between the rotating member of the first rotating device and the rotated member of the speaker unit, and the rotational force of the driving device is sufficiently applied to the rotated member. Can be prevented from being transmitted. Specifically, when the rotating member is a gear and the rotated member has a plurality of teeth corresponding to the gear, it is possible to prevent tooth skipping.

  You may provide the control part which controls rotation of a speaker unit, and the operation part which transmits the signal of the rotation of a speaker unit to a control part. Further, the control unit may control the rotation of the speaker unit by the first rotating device and the second rotating device so that the speaker unit faces a desired or set direction. Further, the operation unit may transmit a signal in a direction in which the speaker unit should be directed to the control unit based on information such as a signal input from the outside. Thereby, the person who listens to the sound emitted from the speaker unit of the electronic device can direct the speaker unit in a desired direction by inputting information about the direction in which the speaker unit should be directed to the operation unit.

  In addition, the control unit receives a signal indicating that the electronic device is in an off state, and controls the first rotating device or the second rotating device to rotate the speaker unit to a steady position. In response to a signal indicating that the device is on, the first rotating device or the second rotating device may control the speaker unit to rotate in a desired or set direction. By providing the electronic apparatus with such a configuration, when the electronic apparatus is turned on, the speaker unit automatically enters a standby state in a desired or set direction. When the electronic device is turned off, the speaker unit is automatically controlled to return to the steady position.

  The electronic device of the present embodiment described above is useful whether it is provided in a car or a house. In this case, the direction of the speaker unit can be arbitrarily adjusted with respect to the person who listens to the sound from the speaker of the electronic device in the interior of a car or in a house. Further, power consumption when changing the direction of the speaker unit can be suppressed. Moreover, the installation space of this electronic device can be reduced.

  FIG. 4 shows an exploded perspective view in which the second housing 6 is disassembled into the outer peripheral cylindrical portion 61 and the lid portion 64. As shown in FIG. 4, the lid 64 includes the opening 5. By having the lid portion 64, it is possible to prevent external force from acting on the speaker unit 2 or dust / dust from entering the space between the speaker unit 2 and the first housing 4. Further, it is possible to suppress interference between the sound wave emitted from the back side of the speaker unit 2 and the sound wave emitted from the front side of the speaker unit 2.

  After the first housing 4 and other components to be described later and the speaker unit 2 are assembled in the second housing 6, a part of the opening of the second housing 6 is covered with the lid portion 64. Thus, the speaker device 1 as an electronic device is manufactured.

  FIG. 5 is a perspective view of the speaker device 1 of FIG. 1 with the cover 64 and the speaker unit 2 removed.

  As shown in FIGS. 2 and 5, a second rotating device 8 is disposed in the vicinity of the central portion of the first housing 4. The second rotating device 8 includes a motor 8a as a driving device, a gear (rotating member) 8b that is rotatably supported by the first housing 4 and to which the rotation of the motor 8a is transmitted, and a second housing 6. And a gear (rotated member) 8c to which the rotation of the gear 8b is transmitted.

  The gear 8 c is provided on a protrusion 62 a included in the bottom 62 of the second housing 6.

  The driving device is not particularly limited as long as it is a device that applies a rotational force to the rotating member. The rotating member and the rotated member may be any member that can transmit a rotational force, and examples thereof include a gear having teeth and a member having a surface that generates a frictional force. The gear 8 c is disposed in the vicinity of the center portion of the second housing 6. The gear 8 c is disposed on the axis of the second housing 6. The gear 8 c only needs to be fixed to the second housing 6, and may be formed integrally or may be formed of a separate member with respect to the bottom 42 of the first housing 4.

  A protrusion 62 a is disposed in the inner peripheral portion 42 a of the bottom portion 42 of the first housing 4. Further, the first casing 4 is rotatably supported with respect to the second casing 6 by the protrusion 43 of the first casing 4.

  When the motor 8a is driven, the rotational force is transmitted to the gear 8b that meshes with the motor 8a and is rotatably supported by the first housing 4, and the gear 8b rotates with respect to the gear 8c.

  Then, the fixed gear 8c and the gear 8b are rotated, and the first casing 4 supported by the second casing 2 so as to rotate freely rotates with respect to the second casing 6. Thereby, the speaker unit 2 accommodated in the first casing 4 and thus the first casing 4 rotates the axis of the first casing 4 and the second casing 6 with the rotation axis (in FIG. 5). , And rotates in the direction of the arrow XY shown in FIG.

  As described above, the second rotating device 8 is arranged in the first housing 4 and the second housing with the axes of the first housing 4 and the second housing 6 as the rotation axis. Since the first casing 4 is rotated with respect to 6, the rotational force of the second rotating device 8 can be made relatively small. Therefore, power consumption based on the second rotating device 8 can be reduced, and an increase in the size of the electronic device based on the second rotating device 8 can be suppressed.

  As described above, the speaker unit 2 is accommodated in the first housing 4. FIG. 6 shows a perspective view of the speaker unit 2 as seen from the back side. On the back surface of the speaker unit 2, protruding first contact portions 5 a and 5 b, a gear (rotated member) 3 c, and second contacted portions 9 a and 9 b corresponding to a contact portion 18 described later are provided. ing.

  The first contact portions 5 a and 5 b are arranged side by side on the side surface on the back side of the speaker unit 2. These first contact portions 5a and 5b are arranged substantially in parallel. The first contact portions 5a and 5b are disposed between the central portion 2a and the outer peripheral portion 2b on the back side surface of the speaker unit 2, and extend from the central portion 2a toward the outer peripheral portion 2b. . The first contact portions 5a and 5b are disposed between the central portion 2a and the outer peripheral portion 2b, so that the first contact portions 5a and 5b are first compared to the case where the first contact portions 5a and 5b are disposed in the central portion 2a. The thickness of the casing 4 in the axial direction can be reduced, and thus the speaker device 1 can be made compact. For this reason, for example, when installing the speaker device 1 of the present embodiment on the front of an automobile or the ceiling of a house, the space for the speaker device 1 can be reduced, so there is a space for placing other electronic devices. Can be secured.

  On the other hand, as shown in FIG. 5 and the like, the first casing 4 is provided with a first contacted portion 10 for fitting and sliding one of the first contact portions 5a and 5b. ing. The first contacted portion 10 is formed in a concave shape as a shape corresponding to the first contact portions 5a and 5b. The first contact portions 5a and 5b extend in an arc shape with the axis around which the speaker unit 2 rotates relative to the first housing 4 as the central axis.

  Of the first contact parts 5a and 5b, for example, the first contacted part 10, one of them has a convex shape and the other has a concave shape. If it is a shape, there will be no limitation in particular. Further, a plurality of first contacted parts 10 may be provided in the first housing 4 corresponding to a plurality of contact parts.

  FIG. 7 is a perspective view when the first housing 4 is cut at a position on the back side from the center. For explanation, a part of the speaker unit 2 is shown. As FIG. 7 shows, the 1st contact part 5a fits into the 1st to-be-contacted part 10, and slides by using the 1st to-be-contacted part 10 as a path | route. As the first contact portion 5a slides with respect to the first contacted portion 10 as a path, the speaker unit 2 can rotate along a desired path.

  The first contact portions 5a and 5b are provided with openings 15a and 15b. The openings 15a and 15b open the side surfaces of the first contact portions 5a and 5b, and are formed along the direction in which the first contact portions 5a and 5b extend. On the other hand, a rod-like member 11 as a member fixed to the first housing 4 is arranged in the first housing 4. This rod-shaped member 11 is fixed to the first housing 4 via a support portion 12. The rod-shaped member 11 passes through the openings 15a and 15b of the first contact portions 5a and 5b.

  Since the bar-shaped member 11 passes through the openings 15a and 15b, the state where the first contact portion 5a is fitted to the first contacted portion 10 can be maintained, and the rotation of the speaker unit 2 can be smoothly performed. Done.

  In addition, when the speaker unit 2 is rotated, it is possible to refrain from using a shaft serving as a rotation axis. For this reason, a rotating shaft can be set to a desired position. Moreover, by refraining from using the shaft as the rotating shaft, the space for arranging the shaft can be eliminated, and the speaker device 1 itself can be downsized. Furthermore, by refraining from using the shaft, the speaker unit 2, the first housing 4 and the second housing 6 can be assembled separately, and when the speaker unit 2 breaks down, the speaker unit 2 2 can be removed and replaced.

The first housing 4, first rotary device 3 for rotating the speaker unit 2 describes the direction you intersecting the axis of the first housing 4 as a rotational axis (broken line C in FIG. 1) It is arranged. The rotation axis also intersects the axis of the speaker unit 2. In the illustrated example, the rotation axis indicated by the broken line C in FIG. 1 is a direction substantially orthogonal to the first housing 4. Further, the rotation axis indicated by the broken line C in FIG. 1 is substantially orthogonal to the axis of the speaker unit 2.

  The first rotating device 3 includes a motor 3a as a driving device, a gear (rotating member) 3b to which the rotation of the motor 3a is transmitted, a gear (rotating member) 3b ′ to which the rotation of the gear 3b is transmitted, and a gear. A gear (a rotated member) 3c provided on the back surface of the speaker unit 2 to which the rotation of 3b ′ is transmitted is constituted by a support portion 3d. The gear 3b and the gear 3b 'are supported on the first casing 4 by a support portion 3d so as to be freely rotatable. The driving device is not particularly limited as long as it is a device that applies a rotational force to the rotating member. The rotating member and the rotated member may be any member that can transmit a rotational force, and examples thereof include a gear having teeth and a member having a surface that generates a frictional force. The first rotating device 3 is disposed between the central portion of the first casing 4 and the outer peripheral cylindrical portion 42 and adjacent to the second rotating device 8.

  When the motor 3a is driven, the rotation is transmitted to the gear 3b meshed with the motor 3a and then to the gear 3b ', and these gears rotate in a chain. Further, the rotation is transmitted to a gear 3 c that meshes with the gear 3 b ′ and is fixed to the side surface on the back side of the speaker unit 2, and the speaker unit 2 rotates with respect to the first housing 4 together with the gear 3 c.

  Thereby, the speaker unit 2 accommodated in the first housing 4 rotates with a direction orthogonal to the axis of the first housing 4 as a rotation axis (a CC broken line in FIG. 1). As shown in FIG. 1, the direction of this rotation is such that the edge portion of the speaker unit 2 is in the direction of arrow Z, that is, in the direction of arrow Z ′ in FIG. As described above, in this embodiment, the speaker unit 2 can be moved in the direction of the arrow Z ′ in FIG. 1 and in the XY direction in FIG. 1 as described above. can do.

  When the speaker unit 2 is rotated by the first rotating device 3, between the motor 3a and the gear 3b to which the rotation of the motor 3a is transmitted in the first rotating device 3, or between the gear 3b and the gear 3b ′. , And the engagement between the rotating members of the second rotating device 3 (hereinafter, abbreviated as “between the motor 3a, the gears 3b, 3b ′, and c”) between the gear 3b ′ and the gear c. ) May be separated, and tooth skipping may occur between the motor 3a and the gears 3b, 3b ′, 3c (the rotational force is not accurately transmitted).

However, it arranged in the first housing 4, the rod-like member 11 which extends substantially parallel to the speaker unit 2 the rotary shaft (dashed line C) is the first contact portion 5a, the opening 15a in 5b, 15b 2 (or more), the engagement between the gears 3b, 3b ′, c in the first rotating device 8 (the connection between the rotating members of the first rotating device 8) is released. It is possible to prevent the rotational force from being transmitted, such as tooth skipping. Further, the motor 3 a and the gears 3 b and 3 b ′ are supported by a support portion 3 d provided in the first housing 4. By using the support portion 3d, it is possible to prevent the engagement between the motor 3a and the gears 3b and 3b ′ (connection between the rotating members included in the first rotating device 8) from separating.
