DETAILED DESCRIPTION OF THE INVENTION

[0024] An example of an embodiment of the present disclosure will be described below with reference to the drawings. In each drawing, the same or equivalent components and parts are designated by the same reference numerals. Furthermore, the dimensional proportions in the drawings are exaggerated for the sake of explanation and may differ from the actual proportions.

[0025] [Embodiment] Fig. 1 shows an image forming apparatus 10 according to an embodiment of the present disclosure. As shown in Fig. 1, the image forming apparatus 10 according to the present disclosure includes an image forming unit 14, a document reading unit 18, an apparatus housing 12, and a user interface 50. In the following description, the side from which a user of the image forming apparatus 10 mainly faces the image forming apparatus 10 (the front side in Fig. 1) will be referred to as the "front," and the opposite side (the back side in Fig. 1) will be referred to as the "rear."

[0026] [Image forming unit 14] Image forming unit 14 is a component that functions as a laser printer and prints an image on recording paper using a laser method, and is a device located at the bottom of image forming device 10 as shown in FIG. 1. Image forming unit 14 includes a toner image forming unit (not shown), a transfer unit that transfers the toner image formed by the toner image forming unit onto recording paper, and a fixing device that fixes the transferred toner image onto the recording paper. Each component related to image forming unit 14 is stored inside device housing 12 and is controlled by a control unit (not shown) based on a print job input by a user's input operation. Furthermore, the recording paper on which the toner image has been fixed by image forming unit 14 is discharged from paper discharge unit 16 to the outside of device housing 12.

[0027] [Document reading unit 18] 1, the document reading unit 18 is a device disposed on the upper side of the image forming apparatus 10. The document reading unit 18 has an ADF (Automatic Document Feeder) that automatically feeds documents (recording paper on which an image is formed), and has the function of reading the image formed on each document and creating electronic data.

[0028] [User Interface 50] The user interface 50 is a device disposed on the front side of the image forming apparatus 10 (the front side in FIG. 1 ) and is a device provided for use by a user of the image forming apparatus 10. The user interface 50 has, as an example, a touch panel 54, which is an example of an input unit in this embodiment, and is also an example of an input device in this embodiment.

[0029] Next, the user interface 50 in this embodiment will be described in detail with reference to FIGS.

[0030] 2 and 3 are perspective views showing the appearance of a user interface 50 according to an embodiment of the present disclosure. As shown in FIGS. 2 and 3, the user interface 50 includes a housing 30, a touch panel 54 that faces forward as described above, and a hinge 56. The hinge 56 is provided at the rear of the housing 30 of the user interface 50, and enables the elevation / depression angle (the horizontal angle relative to the user) of the user interface 50 to be changed when the touch panel 54 is provided on the image forming apparatus 10 as shown in FIG.

[0031] 3, the housing 30 of the user interface 50 according to this embodiment has a first cover 32 and a second cover 34. In other words, in the user interface 50 according to this embodiment, the first cover 32 and the second cover 34 are combined to form the housing 30. As shown in FIG. 4, the second cover 34 has an opening 36 formed at the rear to which the first cover 32 can be detachably attached, and the first cover 32 is attached to the opening 36. In this embodiment, the first cover 32 and the second cover 34 that form the housing 30 may be made of any material that does not easily deform, but as an example, they are made of a hard synthetic resin.

[0032] 3, the first cover 32 has a mesh portion 82 that allows sound waves emitted from a speaker main body 52 (described later) to pass to the outside of the housing 30. In other words, the mesh portion 82 faces the opposite side from the touch panel 54.

[0033] (Internal structure, etc.) Fig. 5 is a cross-sectional view taken along line 3A-3A in Fig. 3, and Fig. 6 is an enlarged view of the periphery of speaker main body 52 in Fig. 5. As shown in Fig. 5, the user interface 50, in an assembled state, has a housing 30, a speaker main body 52, and a partition structure 76 that partitions a first space 72 and a second space 74. Also, as shown in Fig. 5, the user interface 50 in this embodiment further includes a touch panel 54 housed inside the housing 30.

[0034] In the following description, the direction in which speaker main body 52 mainly emits sound, that is, the side facing mesh portion 82 (upper side in FIG. 5), will be referred to as the "front side," and the opposite side will be referred to as the "rear side." The direction facing the front side and the rear side will be referred to as the "thickness direction."

[0035] 4 to 6, etc., in the user interface 50 of this embodiment, the first cover 32 covers the speaker main body 52 when attached to the opening 36 of the second cover 34. Also, as shown in Fig. 4, in the user interface 50 of this embodiment, the entire front surface side of the speaker main body 52 is exposed when the first cover 32 is detached from the second cover 34.

[0036] Also, as shown in Figures 5 to 7, on the back side of the first cover 32 (the side facing the speaker main body 52), a frame-shaped rib 80 protruding toward the back side is formed so as to surround the mesh portion 82.

[0037] 5 and 6, the second cover 34 has a partition wall 60 that extends to separate the front surface side from the back surface side. A support member 58 to which the speaker body 52 (described later) is joined is attached to the partition wall 60, as shown in FIG.

[0038] (Speaker body 52) The speaker body 52 in this embodiment is a so-called loudness speaker, which generates sound by vibrating a vibrator based on an electrical signal transmitted through a signal line (not shown). In this embodiment, the diaphragm of the speaker body 52 is arranged facing upward in FIG. 5, and the speaker body 52 radiates sound toward the front surface. Note that the speaker body 52 in this embodiment is appropriately set and selected depending on the shape of the components to which it is attached, and as an example, the length in the thickness direction is small compared to the diameter.

[0039] As shown in FIGS. 4 to 7 , the support member 58 is a member that attaches the speaker body 52 to the partition wall 60 of the second cover 34, and as shown in FIGS. 5 and 6 , the support member 58 is a member that surrounds the periphery of the speaker body 52 and supports the speaker body 52 at a distance from the partition wall 60. More specifically, the support member 58 has a joint portion 62 that is attached to the partition wall 60 and an enclosure portion 64 that surrounds the speaker body 52, and the speaker body 52 is disposed inside the enclosure portion 64. For this reason, a gap that becomes the rear space 90 in this embodiment is formed between the partition wall 60 and the back surface of the speaker body 52 that is attached to the partition wall 60 via the support member 58, in other words, supported by the support member 58.

[0040] 7, the surrounding portion 64 has a portion cut out in the circumferential direction (the direction perpendicular to the thickness direction) by a notch 66. In other words, the surrounding portion 64 connects the rear space 90 and the storage space 94, which will be described later, by the notch 66.

[0041] (Buffer material 78) 5 to 7, the support member 58 is provided with a buffer material 78 on the front side of the speaker body 52 so as to surround the periphery of the speaker body 52. ​​The buffer material 78 is formed of an elastic material such as EPDM rubber, for example. As shown in FIGS. 5 to 7, the buffer material 78 comes into contact with the protruding ends of the ribs 80 of the first cover 32 when the first cover 32 is attached to the second cover 34.

[0042] The support member 58 and the speaker body 52 may be joined by any method, but as an example, they are joined using an adhesive (not shown). The support member 58 and the buffer material 78 may be joined by any method, but as an example, they are joined using an adhesive (not shown). The support member 58 and the partition wall 60 may be joined by any method, but as shown in FIG. 7, they are attached by a detachable method such as screw fastening. In this embodiment, as shown in FIG. 4, when the first cover 32 is removed from the opening 36 of the second cover 34, the support member 58 including the speaker body 52 is held in a configuration including the second cover 34. In this embodiment, "held by the second cover" means that when the first cover 32 is removed from the opening 36 of the second cover 34, as shown in FIG. 4, the support member 58 including the speaker body 52 is held in a configuration including the second cover 34.

[0043] (Compartment Structure 76) As described above, when the second cover 34 and first cover 32 according to this embodiment are combined, the ribs 80 and the buffer material 78 come into contact with each other, and the space on the front side of the speaker body 52 is partitioned from the periphery of the speaker body 52. ​​That is, in this embodiment, the buffer material 78 interposed between the protruding ends of the ribs 80 of the first cover 32 and the speaker body 52 is an example of the partition structure 76 according to this embodiment.

[0044] More specifically, when the first cover 32 and the second cover 34 are combined, as shown in Figures 5 and 6, a first space 72, which is a space partitioned by the partition structure 76, is formed on the front side of the speaker body 52. ​​Furthermore, a second space 74, which is a space partitioned from the first space 72, is formed in the space inside the housing 30 excluding the front side of the speaker body 52.

[0045] 5 to 7, the second space 74 is further divided into a plurality of spaces. More specifically, the second space 74 has a rear space 90, which is the space behind the speaker body 52, an accommodation space 94 that accommodates functional components different from the speaker body 52, and a connecting space 92 that connects the rear space 90 and the accommodation space 94. In other words, the rear space 90, which is formed on the rear side of the speaker body 52, is connected to the surroundings via the connecting space 92, rather than the speaker body 52.

[0046] 7, a part of the enclosure 64 is cut out by the notch 66, thereby connecting the rear space 90 and the storage space 94. The space connecting the rear space 90 and the storage space 94, which is formed by cutting out a part of the enclosure 64 by the notch 66, is an example of the connecting space 92 in this embodiment.

[0047] In this embodiment, the accommodation space 94 is further divided into a plurality of sections. More specifically, the accommodation space 94 has a first accommodation space 96 and a second accommodation space 98 formed on the rear side of the first accommodation space 96 with the partition wall 60 sandwiched therebetween. As shown in Figures 5 and 6, the first accommodation space 96 is a space in which wiring that transmits electrical signals to the speaker main body 52 (not shown), a control unit that controls the touch panel 54 and the speaker main body 52, and the like are disposed. Note that the touch panel 54 is an example of a functional component different from the speaker main body 52 in this embodiment.

[0048] 5 and 6, the second housing space 98 is arranged in a state in which the display surface of the touch panel 54 (a screen that accepts user input) is exposed on the back surface side of the housing 30. Therefore, in this embodiment, the first space 72 can be said to be located on the opposite side of the second space 74 from the touch panel 54.

[0049] (sound heard by user) Generally, when the speaker body 52 is small, the lower the sound produced by the speaker body 52 (the sound with a relatively low frequency), the harder it is to produce the sound, and the lower the sound emitted from the speaker, the harder it is for the user to hear.

[0050] Furthermore, when the speaker body 52 vibrates and radiates sound waves toward the front surface side, sound waves that are out of phase with the sound waves radiated toward the front surface side are generated on the back surface side of the speaker body 52. ​​When both the sound waves radiated toward the back surface side and the sound waves radiated toward the front surface side reach the user, the sound waves tend to interfere with each other and cancel each other out for the user. In other words, when both the sound waves radiated toward the front surface side and the sound waves radiated toward the back surface side of the speaker body 52 reach the user, the user finds it even more difficult to hear the low-frequency range of the sound emitted from the speaker body 52.

[0051] Here, according to the configuration of the user interface 50 of this embodiment, the first space 72 created on the front surface side of the speaker body 52 and the second space 74 created on the back surface side of the speaker body 52 are partitioned, and therefore the volume of the second space 74 is large. In other words, according to the configuration of the user interface 50 of this embodiment, it is possible to move the sound waves radiated into the second space 74 away from the mesh portion 82, and therefore it is easy to suppress interference with the sound waves radiated into the first space 72.

[0052] The present inventors created a configuration equivalent to the user interface 50 according to this embodiment, emitted sound from the speaker main body 52, and measured the sound emitted from the speaker main body 52. ​​The upper diagram in FIG. 8 is a spectrum diagram showing the sound included in the audio data emitted from the speaker main body 52, and the lower diagram in FIG. 8 is a spectrum diagram showing the measurement result of the sound emitted from the speaker main body 52.

[0053] As mentioned above, in the example shown in Figure 8, the sound contained in the audio data shown in the upper figure is not accurately represented, as shown in the lower figure, and the peaks in the sound pressure level around 300 Hz and 400 Hz are smaller in the lower figure than in the upper figure.

[0054] However, as shown in the lower diagram of Figure 8, the sound emitted from the speaker has clearly higher sound pressure levels at 600 Hz, which is twice the frequency of 300 Hz, and at 900 Hz, which is three times the frequency. The sound pressure level at 800 Hz, which is twice the frequency of 400 Hz, is also clearly higher. Additionally, the sound pressure level at 1000 Hz (1 kHz), which is twice the frequency of 500 Hz, is also clearly higher. In other words, with the configuration and structure of the user interface 50 according to this embodiment, even for frequencies in the low-frequency range (500 Hz or lower in this example) included in the audio data, sounds with frequencies two or three times the frequency of the frequencies are likely to be measured.

[0055] Furthermore, there is a known phenomenon known as the missing fundamental, in which, even if the sound pressure level of a sound of a certain frequency is unclear, if a sound of a frequency that is an integral multiple of that frequency is clearly audible, the sound of that frequency is perceived by humans. Therefore, as shown in the lower diagram of Figure 8, even if sounds of 300 Hz and 400 Hz are actually difficult for a user to hear, the user interface 50 according to this embodiment makes it easy to recognize the sounds of 300 Hz and 400 Hz due to the above phenomenon.

[0056] The user interface 50 and image forming apparatus 10 according to this embodiment provide the following functions and effects.

[0057] (Action and effect) In the user interface 50 according to this embodiment, a first space 72 on the front side of the speaker main body 52 and a second space 74 on the back side are partitioned with the first cover 32 attached to the second cover 34. This makes it difficult for sound waves radiated from the speaker main body 52 into the first space 72 to mix with sound waves of an opposite phase radiated into the second space 74. Therefore, according to the user interface 50 according to this embodiment, low-pitched sounds are easier to hear compared to a user interface 50 in which the speaker main body 52 is located between the first cover 32 and the second cover 34 to which the first cover 32 is detachable, or a configuration in which the space on the front side of the speaker main body 52 is connected to the space on the back side.

[0058] Furthermore, in the user interface 50 according to this embodiment, the compartment structure 76 is formed of a frame-shaped rib 80 and a buffer material 78 interposed between the speaker and the rib 80. Therefore, with the user interface 50 according to this embodiment, a gap is less likely to occur between the first space 72 and the second space 74 compared to a configuration in which the compartment structure 76 is formed only by the rib 80 protruding from the first cover 32.

[0059] Furthermore, in the user interface 50 according to this embodiment, the entire front surface of the speaker main body 52 is exposed when the first cover 32 is detached from the second cover 34. In other words, according to the user interface 50 according to this embodiment, the speaker can be assembled by removing the first cover 32. Therefore, according to the user interface 50 according to this embodiment, the assembly work of the speaker main body 52 is easier than in a configuration in which only a portion of the front surface is exposed when the first cover 32 is detached from the second cover 34.

[0060] Furthermore, the user interface 50 according to this embodiment has an accommodation space 94 that accommodates functional components different from the speaker body 52, and the second space 74 connects the rear space 90 to the accommodation space 94. In other words, according to the user interface 50 according to this embodiment, the second space 74 extends outward from the rear side of the speaker body 52. ​​Therefore, according to the user interface 50 according to this embodiment, it is easier to hear low-pitched sounds compared to when the second space 74 is provided only on the rear side of the speaker body 52.

[0061] Furthermore, the user interface 50 according to this embodiment has a notch 66 in a part of the enclosure 64 that surrounds the periphery of the speaker main body 52, and the notch 66 forms a connecting space 92 that connects the rear space 90 and the storage space 94. Therefore, according to the user interface 50 according to this embodiment, the connecting space 92 can be created by the support member 58.

[0062] Furthermore, in the user interface 50 according to this embodiment, the speaker body 52 is detachably attached integrally with the support member 58 to the second cover 34. Therefore, according to the user interface 50 according to this embodiment, the speaker body 52 and the support member 58 can be replaced integrally by removing the first cover 32.

[0063] Furthermore, in the user interface 50 according to this embodiment, the touch panel 54 that receives input operations from the user is disposed in the second space 74. Therefore, according to the user interface 50 according to this embodiment, the device can be used for input operations by the user.

[0064] Furthermore, the first space 72 of the user interface 50 according to this embodiment is located on the opposite side of the second space 74 from the touch panel 54. Therefore, according to the user interface 50 according to this embodiment, the user interface 50 is made smaller than a configuration in which the speaker main body 52 is arranged alongside the touch panel 54 along the cover surface (the surface in the direction in which the first cover 32 extends). Furthermore, according to the user interface 50 according to this embodiment, the mesh portion 82 is located on the opposite side of the image forming apparatus 10 from the front, which is the side from which the user operates the apparatus, and therefore dirt is less likely to get inside the housing 30 even when the user operates the apparatus with wet hands, for example.

[0065] Furthermore, the image forming apparatus 10 according to this embodiment uses the user interface 50 having the above-described configuration. Therefore, the user interface 50 according to this embodiment can obtain a sound generation function without disposing the speaker main body 52 on the main body of the image forming apparatus 10.

[0066] (Variation) In the above description, the image forming apparatus 10 is described as an apparatus in which the user interface 50 has the compartment structure 76 according to the present embodiment. However, examples of the apparatus according to the present embodiment are not limited to this. For example, the functions of the first cover 32 and the second cover 34 may be performed by the apparatus housing 12 of the image forming apparatus 10, and the speaker main body 52 and the compartment structure 76 may be configured to be included in the apparatus housing 12 of the image forming apparatus 10. In other words, the image forming apparatus 10 may be another example of the "apparatus" according to the present embodiment. In this case, the housing space for housing any of the functional components, including the image forming unit 14, the document reading unit 18, etc., of the image forming apparatus 10 may be connected to the rear space behind the speaker main body 52 by a connecting space.

[0067] Furthermore, in the above description, the user interface 50 having the touch panel 54 has been described as an example of a device in this embodiment, but the example of the device in this embodiment is not limited to this. For example, the device may have the configuration described above, without including an input unit such as the touch panel 54, but instead using a housing having a first cover and a second cover, a speaker body, and a compartment structure. In other words, the device in this embodiment is not limited to an input device or an image forming device 10.

[0068] In the above example, the user interface 50 has the touch panel 54 in the second housing space 98, but the configuration of the user interface 50 according to this embodiment is not limited to this. For example, in addition to the touch panel 54, other functional components such as a display that only presents information to the user, a keyboard, etc. may also be provided.

[0069] In the above description, the first space 72 is located on the opposite side of the second space 74 from the touch panel 54, but the configuration of the user interface 50 according to the present embodiment is not limited to this. For example, the first cover 32 may be provided on the front side of the image forming apparatus 10, with the mesh portion 82 located on the front side.

[0070] In the above description, the speaker body 52 is integrated with the support member 58 and attached to the second cover 34, but the configuration of the user interface 50 according to this embodiment is not limited to this. For example, the support member 58 may be permanently attached to the partition wall 60, or the speaker body 52 and the support member 58 may be detachably attached.

[0071] In the above description, the support member 58 has a notch 66 in a part of the enclosure 64, and the notch 66 forms the connecting space 92. However, the configuration of the user interface 50 according to this embodiment is not limited to this. For example, the enclosure 64 may not have the notch 66, and the connecting space 92 connecting the rear space 90 and the storage space 94 may be formed by a hole opened in the partition wall 60.

[0072] In the above description, the connecting space 92 connecting the rear space 90 and the storage space 94 in the user interface 50 is formed by the support member 58, but the configuration of the user interface 50 according to this embodiment is not limited to this. For example, the enclosure 64 of the support member 58 may be configured to cover the rear side of the speaker main body 52 while being in contact with the partition wall 60, and the connecting space 92 may not be provided.

[0073] In the above description, the entire front surface of the speaker body 52 is exposed when the first cover 32 is removed, but the configuration of the user interface 50 according to this embodiment is not limited to this. For example, the speaker body 52 may be configured not to be exposed even when the first cover 32 is removed, and the speaker body 52 may be configured to be more firmly attached to the second cover 34.
