Description

  The present invention relates to an electronic device that supports a first housing and a second housing so as to be openable and closable by a hinge mechanism, and in particular, has a configuration in which a speaker opening provided in a first housing is covered by a second housing. Regarding equipment.

  Conventionally, in an electronic device such as a digital camera or a video camera, an electronic device having a so-called vari-angle type and tilt type image display unit provided with an image display unit rotatably attached to the device main body by a hinge mechanism. Equipment is widespread.

  For example, an imaging device with a biaxial vari-angle image display unit can be rotated to any angle with the image display unit open sideways so that you can shoot while checking the subject at various angles. It is. Even in an imaging apparatus having a uniaxial tilt type image display unit, the image display unit can be rotated at various angles in one direction, and similarly, shooting can be performed while checking the subject at various angles. it can.

  Patent Document 1 includes a display unit housing including an image display unit, a main body housing including an imaging unit, and a hinge unit that couples each, and the hinge unit includes the display housing and the main body housing. A digital camera is described which is a biaxial hinge that is openably and closably connected.

  In addition, electronic devices such as digital cameras and video cameras tend to be desired to be smaller and thinner in order to improve portability. The number of devices equipped with a touch panel type operation unit is increasing in the image display unit. On the other hand, downsizing is desired. On the other hand, the image display unit is as large as possible in order to improve the operability of touch operation and secure a display area during shooting. It needs to be a size.

  In addition, the number of operation buttons on the surface of the main body tends to be reduced due to the touch panel, but physical buttons are more reliable for switching from shooting to playback and switching to a specific mode. It is possible to select before starting, and it is better to leave the minimum necessary items rather than losing everything.

  When priority is given to miniaturization of the main body and securing of the image display section, an image pickup apparatus equipped with a single-axis tilt type that occupies a small space in the main body in the hinge mechanism section is suitable.

  FIG. 12 shows a configuration using a single-axis tilt hinge. As described above, an example of a configuration in which necessary operation members and mounting components are laid out with priority given to miniaturization of a digital camera and securing of an image display unit is shown. FIG. 12A is a perspective view from the front side in a state where the display unit housing 122 is closed, and FIG. 12B is a perspective view from the back side in a state where the display unit housing 122 is closed, and FIG. ) Shows a state in which the display unit housing 122 is tilted by about 90 degrees from the state of FIG. As a result of downsizing the main body as shown in FIG. 12 (b), the display unit housing 122 has the minimum necessary size determined from the operability, and the projection area of the main body housing 123 is equal to or equal to the display unit housing 122. It becomes the size with the restriction of. The back side of the digital camera 121 is occupied by the image display unit, and other operation buttons cannot be arranged.

  Further, in the main body casing 123, it is necessary to efficiently accommodate components such as a lens barrel, a battery, a mounting component, and an operation member. In the digital camera, the position of the operation unit is important. As a result of laying out with priority on operability, there is a configuration in which the operation unit 124 and the connection unit 125 are laid out on the side of the main body as shown in FIG. In consideration of the fact that the upper surface 123a of the main body becomes difficult to operate when the display housing 122 is tilted by 180 degrees, no operation member is provided, only the microphone hole 126 is provided, and mounting parts such as cables are provided on the upper surface inside the main body. Laid out.

  Further, when considering the layout, the speaker 127 is relatively large and thick, and thus it is difficult to place the speaker 127 on the side surface of the main body. Considering the space left inside the main body housing and the place where it can be opened to the outside, the space efficient position is the back surface of the main body housing as shown by the speaker sound outlet 123b in FIG.

  An example of a configuration that has been laid out efficiently will be described later in detail in the present embodiment.

  As shown in FIG. 12C, the speaker sound outlet 123b is exposed only when the display housing 122 is tilted, and the display housing 122 is formed by providing a gap between the display housing 122 and the main housing 123. The sound of the speaker 127 can reach the user even in the closed state.

  FIG. 13 is a cross-sectional view cut along a cross section CC in FIG. 12C, and shows the speaker 127 and the speaker holding member 131 assembled to the main body casing 123.

  The speaker 127 is fixed to the back cover 123c of the main body casing 123 while being charged through the cushion 132 and the dustproof sheet 133, and is fixed to the speaker holding member with a double-sided tape 134 so as not to rattle up and down. .

  In general, the speaker holding member 131 desirably emits sound from the front of the speaker 127 without opening the back of the speaker 127 as much as possible in order to stabilize the sound characteristics of the speaker 127. The speaker 127 is pressed against the back cover 123c so that sound is surely emitted from the opening 123b.

  There is also a method as in Patent Document 2 in which a speaker is provided on the display unit housing side when a speaker cannot be provided on the main body side. However, since it is necessary to further reduce the size of the display unit as small as possible to reduce the size of the main unit, the buttons displayed on the screen are reduced when operating with the touch panel, or the display image during shooting is difficult to see and the operability is improved. There was a risk of decline.

JP 2012-105069 A Japanese Patent No. 4322955

  However, since the gap between the main body casing 123 and the display section casing 122 is set as small as possible for miniaturization and thinning, the sound volume coming out of the gap with the main body casing 123 when the display section casing 122 is closed is the minimum necessary. It is. On the other hand, the sound emitted from the speaker 127 when the display housing 122 is opened is amplified in a specific direction by the display housing 122 on the back surface of the display housing 122 with the same effect as the horn. Therefore, there is a problem that the way the user hears the sound differs greatly when the display unit housing 122 is closed and when the display unit housing 122 is opened.

  When the display unit housing 122 is open, the sound is large and can be heard in a well-balanced manner. However, when the display unit housing 122 is closed, the sound is smaller than when the display unit housing 122 is open, making it difficult to hear middle and low sounds.

  Therefore, the present invention supports an openable and closable display housing and body housing by a hinge mechanism, and an electronic device having a speaker on the back of the body housing does not require a complicated mechanism and the display housing is opened. The object is to reduce the difference between the sound of the state and the state where the display unit housing is closed.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an external perspective view showing a configuration example of an imaging apparatus (digital camera), FIG. 1 (a) is an external perspective view seen from the front side, and FIG. 1 (b) is an external perspective view seen from the back side. FIG.

  The digital camera 1 includes a display unit casing 2 (second casing) having a display panel 5, a main body casing 3 (first casing) on the camera body side, the display unit casing 2, and the main body casing. It consists of a hinge part which connects 3.

  The display panel 5 is equipped with an electrostatic touch panel, and an operation button is displayed on the display panel, and a function can be switched by touching a position corresponding to the displayed button.

  By touch operation, subject selection, shutter release operation, zoom-in and zoom-out operations can also be performed.

  FIG. 2 is a perspective view showing a state in which the display unit housing 2 is opened in the direction indicated by the arrow A with respect to the main body housing 3.

  The hinge portion 4 has a uniaxial hinge mechanism, and the display unit housing 2 is supported to be openable and closable with respect to the main body housing 3. In the present embodiment, the movement of the display unit housing 2 with respect to the main body housing 3 is an opening / closing operation, but either the display unit housing 2 or the main body housing 3 may be used as a reference. 2 and the main body housing 3 need only be relatively opened and closed.

  Since the photographer can freely change the angle of the display unit housing 2 with respect to the main body housing 3 according to the camera angle, it is suitable for various situations. As shown in FIG. 2A, when the hinge part is opened on the upper side of the main body, a state suitable for low-angle shooting for shooting a subject at a low position is obtained. On the contrary, at the time of high-angle shooting in which the subject is photographed so as to look down from a high position, as shown in FIG. 2B, it can be handled by holding the body housing 3 upside down so that the hinge portion is located below the body. .

  Since the main housing 3 and the display housing 2 are connected by the hinge unit 4, the photographer can freely change the angle of the display housing 2 with respect to the main housing 3 in accordance with the posture for photographing. You can shoot while always checking the subject even at low and high angles. Since the rotation axis of the tilt type hinge unit 4 is provided inside the main body housing 3, an opening 302 that allows the hinge unit 4 to be accommodated and rotated is required.

  Similar to the configuration described in the background art, a speaker sound emission port 301 is provided on the back surface of the main body by downsizing and thinning the main body, and the internal configuration will be described later.

  The internal layout of the main body housing 3 of this embodiment will be described with reference to FIG. FIG. 3A is a diagram showing the appearance of the main body 3 viewed from the front, and FIG. 3B shows the layout of the components inside the main body as viewed from the front. FIG. 3C shows an internal layout viewed from the right side of the main body.

  Since the digital camera 1 supports a high angle and a low angle with a one-axis tilt, the lens barrel unit 7 is arranged in the center of the main body housing 3 assuming that it can be set upside down, and there is a space left and right. Therefore, the battery 8 is arranged on the right side and the substrates 9 are arranged on the left side.

  As can be seen from FIG. 3 (c), when trying to make the main body as small and thin as possible, there is a trade-off between the projected area from the front and the thickness of the main body. The thickness of 8 becomes dominant.

  In this embodiment, in order to make the total thickness of the digital camera as thin as possible, the battery housing portion of the main body housing 3 has a convex shape (3a) as shown in FIG. 2, and the display housing 2 has a concave shape ( 2a), and the empty space of the display unit housing 2 is also used.

  As shown in FIG. 8A, the speaker 6 is attached to the speaker housing recess 15a of the speaker holding member 15, and the opening 15b is provided for passing the connector 6a and the lead wire 6b. The speaker 6 is positioned by the outer shape of the speaker 6 and the speaker housing recess 15a, and the back surface of the speaker 6 is fixed by an adhesive member such as a front tape (not shown). In addition to the opening 15b, the speaker holding member 15 is provided with an opening 15c for allowing sound from the back of the speaker 6 to pass through.

  As shown in FIG. 8B, the speaker holding member 15 is provided with a U-groove 15d from the opening 15c toward the upper surface of the main body. A sound path opening / closing member 18 is fixed to the mounting surface 15 e on the speaker holding member 15, and the U groove 15 d forms a sound path for guiding the sound on the back side of the speaker 6 by covering the opening with the sound path opening / closing member 18. . The sound path opening / closing member 18 is an elastically deformable thin plate material such as SUS430 or phosphor bronze, and is positioned and fixed by caulking the positioning bosses 15f and 15g. Airtightness can be increased by increasing the number of caulking points as necessary.

  The sound path opening / closing member 18 can be elastically deformed with the deforming portion 18a as a fulcrum, and the sound path opening / closing member tip 18b can be displaced by elastic deformation. Further, the portion of the sound path opening / closing member 18 that fits into the U-groove 15d is processed into a U-shaped 18c so that a large gap is not generated in the sound path even when the sound path opening / closing member 18 is displaced. Yes. A rib 15h is provided at the tip of the U groove 15d serving as the sound path outlet, and a slit 15i is provided at both ends of the rib 15h so as to escape the tip of the U-shaped bent portion 15c of the sound path opening / closing member 18. In the state where only the speaker holding member 15 and the sound path opening / closing member 18 are assembled, the sound path by the U groove 15d is closed by the abutment of the rib 15h at the front end of the sound path opening / closing member 18 and the U groove 15d.

  FIG. 9 is a perspective view illustrating the relationship between the sound path opening / closing member 18, the base member 16, and the hinge unit 4. 9A is a perspective view showing the base member 16 from the back side of the main body, and FIG. 9B is a state in which the speaker holding member 15, the sound path opening / closing member 18 and the base member 16 are combined, and the hinge unit 4. It is a perspective view from the main body back side for demonstrating a relationship.

  As shown in FIG. 9A, the base member 16 has a blindfolding wall 16a that escapes the rotation range of the hinge unit 4, and an opening 16b is provided in the blindfolding wall 16a. By providing the opening 16b, the sound that has passed through the U-groove 15d from the back surface of the speaker 6 can escape from the opening 16b to the opening 302 of the main body housing 3.

  As shown in FIG. 9B, the tip end portion 18b of the sound path opening / closing member 18 can project from the opening portion 16b of the base member 16, and when it is assembled to the hinge unit 4 as shown by the arrow B, the display unit frame The sound path opening / closing member distal end portion 18b contacts the abutting portion 403a of 403. When the hinge unit 4 is closed, the abutting portion 403a pushes the tip of the sound path opening / closing member 18b, and the sound path opening / closing member 18 is elastically deformed. Thus, the sound path is opened with the hinge unit 4 closed. Further, by providing a notch 403b in the vicinity of the rotation shaft 404 of the display unit frame 403, it is easier for sound to pass.

  10A and 10B are cross-sectional views taken along the U-groove 15d. FIG. 10A shows a state in which the display unit housing 2 is opened, and FIG. 10B shows a state in which the display unit housing 2 is closed. .

  As shown in FIG. 10A, when the display housing 2 is opened, the tip 18b of the sound path opening / closing member 18 is in contact with the rib 15h provided at the U groove outlet, and the sound path opening / closing member 18 is in a flat state. is there. At this time, the sound path on the back surface of the speaker holding member 15 is closed by closing the rib 15h and the sound path opening / closing member 18, and the sound directed from the speaker 6 toward the back surface side of the speaker holding member 15 is U-groove 15d of the speaker holding member. The sound is emitted only from the sound outlet 301 in front of the speaker 6.

  As shown in FIG. 10B, when the display unit housing 2 is closed, the abutment part 403a of the display unit frame of the hinge unit 4 pushes the tip 18b of the sound path opening / closing member 18, whereby the sound path opening / closing member 18 is moved. Due to elastic deformation, a gap is formed between the rib 15h in the speaker holding member U groove and the sound path opening / closing member 18. Sound from the speaker 6 toward the back side of the speaker holding member 15 passes through the U groove 15b of the speaker holding member 15 and the opening 16b of the base member 16 in this order, and is emitted from the hinge opening 302 of the main body housing 3. Therefore, both the sound from the sound outlet 301 on the back of the main body housing 3 and the sound from the hinge opening 302 are delivered, and as a result, the difference in volume between when the display housing 2 is closed and when it is opened. Can be shortened.

  As described above, since the second sound emission port can be opened and closed in conjunction with the opening and closing operation of the hinge unit without disposing a drive source and drive mechanism in the main body housing, the structure is simple and the cost is reduced. The change in volume due to the opening and closing of the housing can be reduced. And even if you have to place a speaker on the back of the main unit housing due to the downsizing of the main unit and the size of the display panel, you can increase the choice of speakers and reduce the constraints on the design by eliminating problems in practice. it can.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary. For example, in an electronic device that supports a first housing and a second housing so as to be openable and closable by a hinge mechanism, a speaker is provided in one of the housings, and the sound emission port of the speaker is the other housing As long as it is an electronic device that opens and closes the second sound emission opening in conjunction with the hinge rotation, the electronic device other than the imaging device described above can be applied.
