Also, although not shown in the figure, the axis along the +X direction is the X axis, the axis along the +Y direction is the Y axis, and the axis along the +Z direction is the Z axis.

[0009] Fig. 2 is an exploded perspective view showing the exterior housing 2 as viewed from the +Z direction, and Fig. 3 is an exploded perspective view showing the exterior housing 2 as viewed from the -Z direction. As shown in Figs. 2 and 3, the exterior housing 2 includes an upper panel 21, a lower panel 22, and a housing 3, and is configured by combining the upper panel 21, the lower panel 22, and the housing 3.

[0010] [Configuration of Upper Panel] The upper panel 21 is configured in the shape of a rectangular plate. The upper panel 21 is fixed to the housing 3 so as to cover a later-described upper surface 3A of the housing 3 in the +Z direction, thereby configuring the top surface 2A. The upper panel 21 is configured by combining a first cover 21A that covers a portion of the upper surface 3A in the -X direction and a second cover 21B that covers a portion of the housing 3 in the +X direction. The upper panel 21 has a plurality of openings 211, 212, 213, and 214 that expose a portion of each of the plurality of controls 5 in the +Z direction.

[0011] The opening 211 is provided in the first cover 21A in accordance with the rotor unit 61 (described later) of the jog dial 6. The opening 211 is formed in a circular shape when viewed from the +Z direction, and the +Z-direction portion of the rotor unit 61 is disposed inside the opening 211. The opening 212 is provided in the first cover 21A in accordance with the adjustment dial 64 (described later) of the jog dial 6. The opening 212 is provided in a position in the +X direction and +Y direction relative to the opening 211.

The +Z direction portion of the second operation button 71B is disposed inside the opening 213B.

[0013] The openings 214 are provided in the corners of the second cover 21B in the +X direction and the +Y direction. The openings 214 include openings 214A, 214B, and 214C. Each of the openings 214A, 214B, and 214C is provided in a circular shape corresponding to the corresponding one of the three rotary volumes 81 included in the equalizer adjustment device 8. The shaft 83 of each rotary volume 81 is inserted through the corresponding opening 214 along the Z axis.

[0014] [Configuration of Lower Panel] The lower panel 22 is configured in the shape of a rectangular plate. The lower panel 22 is fixed to the housing 3 so as to cover a bottom surface 3B (described later) of the housing 3 in the -Z direction, thereby configuring the bottom surface 2B. The lower panel 22 has a notch 221. The notch 221 is provided on the -Y direction periphery of the lower panel 22 at a position offset in the -X direction from the center on the X axis. The notch 221 is a recess cut out in a concave shape in the +Y direction from the -Y direction periphery. A junction channel 366 (described later) of the housing 3 is disposed within the notch 221, and liquid that has flowed through the junction channel 366 is discharged to the outside of the exterior housing 2 through the notch 221.

[0015] [General Configuration of Housing] The housing 3 is made of a waterproof material such as metal or synthetic resin, and houses multiple electronic boards 4 and supports multiple controls 5. As shown in Figures 2 and 3, the housing 3 has a top surface 3A, a bottom surface 3B, a front surface 3C, a back surface 3D, a left side surface 3E, and a right side surface 3F. In addition, as shown in Figure 2, the housing 3 has a recess 31 recessed in the -Z direction from the end of the housing 3 in the +Z direction.

[0016] The top surface 3A and the bottom surface 3B are surfaces opposite each other along the Z axis. The top surface 3A faces the +Z direction, and the bottom surface 3B faces the -Z direction. The top surface 3A is located in the -Z direction relative to the +Z direction edges of the front surface 3C, back surface 3D, left side surface 3E, and right side surface 3F. Multiple electronic boards 4 are attached to the bottom surface 3B. The front surface 3C and back surface 3D are surfaces opposite each other along the Y axis. The front surface 3C faces the -Y direction, and the back surface 3D faces the +Y direction. The left side surface 3E and the right side surface 3F are surfaces opposite each other along the X axis. The left side surface 3E faces the -X direction, and the right side surface 3F faces the +X direction.

[0017] The recess 31 is seamless like a bathtub. The surface of the recess 31 facing the +Z direction constitutes the top surface 3A, and the surface of the recess 31 facing the -Z direction constitutes the bottom surface 3B. The inner side surfaces of the recess 31 constitute the inner surfaces of the front surface 3C, back surface 3D, left side surface 3E, and right side surface 3F. The partition 32 divides the space within the recess 31 into a space in the +X direction and a space in the -X direction. The partition 32 stands up from the top surface 3A and extends along the Y axis. Other components of the housing 3 will be described in detail later.

[0018] [Configuration of Electronic Boards] Figure 4 is a view of the audio device 1 from the -Z direction with the lower panel 22 removed. The multiple electronic boards 4 are attached to the bottom surface 3B of the housing 3. Each of the multiple electronic boards 4 detects a user's operation on a corresponding one of the multiple operators 5, and outputs a signal corresponding to the detected operation. As shown in Figure 4, the multiple electronic boards 4 include a jog operation detection board 41, a pressing operation detection board 42, and a rotation operation detection board 43.

[0019] The jog operation detection board 41 is disposed approximately in the center of the bottom surface 3B when viewed from the -Z direction. The jog operation detection board 41 detects the user's rotation operation and pressing operation on the rotating body unit 61 of the jog dial 6. For example, the jog operation detection board 41 detects the rotation direction and rotation angle of the rotating body unit 61. When viewed from the +Z direction or the -Z direction, the jog operation detection board 41 is disposed within an insertion opening 331 of the first arrangement section 33, which will be described later.

[0020] The pressing operation detection board 42 is provided at a corner of the bottom surface 3B in the -X and -Y directions when viewed from the -Z direction. The pressing operation detection board 42 detects the user's pressing of the operation buttons 71A, 71B of the push button device 7. As will be described in detail later, the pressing operation detection board 42 has two light-emitting elements 421 and two switches 422. The rotation operation detection board 43 detects the user's rotation of the three rotary volumes 81 of the equalizer adjustment device 8. More specifically, the rotation operation detection board 43 detects the rotation angle of each rotary volume 81 based on the voltage output from each rotary volume 81.

[0021] [Configuration of the Housing] FIG. 5 is a perspective view showing the housing 3, and FIG. 6 is a plan view showing the top surface 3A of the housing 3. In FIG. 6, the area that has been subjected to the water-repellent treatment is indicated by diagonal lines. As shown in FIGS. 5 and 6, the housing 3 further includes a first arrangement section 33 in which the jog dial 6 is arranged, a second arrangement section 34 in which the push button device 7 is arranged, a third arrangement section 35 in which the equalizer adjustment device 8 is arranged, and an exhaust path 36. The first arrangement section 33 and the second arrangement section 34 are provided in a first area 3A1 on the top surface 3A in the −X direction relative to the partition section 32. The third arrangement section 35 is provided in a second area 3A2 on the top surface 3A in the +X direction relative to the partition section 32.

[0022] [Configuration of the Discharge Path] Figure 7 is a cross-sectional view of the housing 3 taken along line VII-VII in Figure 6, viewed from the -Y direction. First, the discharge path 36 will be described. The discharge path 36 is provided on the upper surface 3A and is a flow path that discharges liquid that has infiltrated into the upper surface 3A through the openings 211 to 214 of the upper panel 21 to the outside of the housing 3, and ultimately to the outside of the exterior housing 2. As shown in Figures 6 and 7, the discharge path 36 has a first discharge path 361, a second discharge path 362, a third discharge path 363, a fourth discharge path 364, a fifth discharge path 365, a junction path 366, and a discharge port 367.

[0023] As shown in FIG. 6 , the first discharge path 361 is a groove provided in the first arrangement section 33. The first discharge path 361 extends in the −Y direction from approximately the center of a second liquid guide section 334 (described later) of the first arrangement section 33. The first discharge path 361 is inclined so as to be positioned in the −Z direction as it approaches the −Y direction. The +Y direction portion of the first discharge path 361 is connected to the −Y direction portions of each of a first liquid guide section 333 and a second liquid guide section 334 (described later) of the first arrangement section 33. The −Y direction portion of the first discharge path 361 is connected to the junction channel 366. The first discharge path 361 discharges liquid that has entered the first liquid guide section 333 and the second liquid guide section 334 to the junction channel 366.

[0024] The second discharge path 362 is a groove portion provided between the first arrangement portion 33 and the second arrangement portion 34, extends along the −Y direction, which is the direction of liquid flow in the first discharge path 361, and allows liquid to flow through. That is, the second discharge path 362 is disposed outside the first arrangement portion 33 and in the −X direction relative to the first arrangement portion 33. The +Y direction portion of the second discharge path 362 is connected to the inner edge of the upper surface 3A in the +Y direction, and the −Y direction portion of the second discharge path 362 is connected to the third discharge path 363. The second discharge path 362 is inclined so as to be positioned in the −Z direction as it approaches the −Y direction. The second discharge path 362 guides liquid that has flowed in the −X direction from a first inclined portion 3351 (described later) of the first arrangement portion 33 to the third discharge path 363.

[0025] The third discharge path 363 is a groove extending along the inner edge of the upper surface 3A in the -Y direction. As shown in FIG. 7 , the third discharge path 363 extends along the X axis, which intersects with the extension direction of the second discharge path 362. That is, the third discharge path 363 extends intersecting with the second discharge path 362, and is configured to allow the liquid that has flowed through the second discharge path 362 to flow therethrough. The third discharge path 363 is inclined so as to be positioned in the -Z direction as it approaches the +X direction. The -X direction portion of the third discharge path 363 is connected to the inner edge of the upper surface 3A in the -X direction. That is, the third discharge path 363 is connected to the second arrangement portion 34. The +X direction portion of the third discharge path 363 is connected to the junction channel 366. The third discharge path 363 discharges the liquid discharged from the second arrangement portion 34 and the liquid guided by the second discharge path 362 to the junction channel 366.

[0026] As shown in FIG. 6 , the fourth discharge path 364 is a groove portion provided between the first region 3A1 and the second region 3A2, extending along the liquid flow direction in the first discharge path 361 and allowing liquid to flow therethrough. That is, the fourth discharge path 364 is disposed outside the first arrangement portion 33 and in the +X direction relative to the first arrangement portion 33. Specifically, the fourth discharge path 364 is disposed along the Y axis in the portion where the partition portion 32 is provided. The +Y direction portion of the fourth discharge path 364 is connected to the inner edge of the upper surface 3A in the +Y direction, and the −Y direction portion of the fourth discharge path 364 is connected to the fifth discharge path 365. The fourth discharge path 364 is inclined so as to be positioned in the −Z direction as it extends in the −Y direction. The fourth discharge path 364 guides liquid that has flowed in the +X direction from a second inclined portion 3352 (described later) of the first arrangement portion 33 to the fifth discharge path 365. The second region 3A2 is inclined so as to be positioned in the −Z direction as it moves in the −X direction and the −Y direction. Therefore, the liquid that has entered the second region 3A2 flows along the second region 3A2 and is guided to the fourth discharge path 364 or the fifth discharge path 365.

[0027] The fifth discharge path 365 is a groove extending along the inner edge of the upper surface 3A in the -Y direction and is provided on the opposite side of the junction channel 366 from the third discharge path 363. As shown in FIG. 7 , the fifth discharge path 365 extends along the X axis intersecting the extension direction of the fourth discharge path 364. That is, the fifth discharge path 365 extends intersecting with the fourth discharge path 364 and is configured to allow the liquid that has flowed through the fourth discharge path 364 to flow therethrough. The fifth discharge path 365 is inclined so as to be positioned in the -Z direction as it extends in the -X direction. The +X direction portion of the fifth discharge path 365 is connected to the inner edge of the upper surface 3A in the +X direction. That is, the fifth discharge path 365 is connected to the second region 3A2. The -X direction portion of the fifth discharge path 365 is connected to the junction channel 366. The fifth discharge path 365 discharges the liquid guided by the fourth discharge path 364 and the liquid flowing in from the second region 3A2 to the junction path 366.

[0028] As shown in FIGS. 6 and 7 , the junction channel 366 is located at the center of the X-axis on the inner edge of the upper surface 3A in the -Y direction. Specifically, the junction channel 366 is located in the -Y direction relative to the rotation axis Rx of the jog dial 6. The junction channel 366 opens to the upper surface 3A and extends in the -Z direction. The junction channel 366 is connected to the first discharge path 361, the third discharge path 363, and the fifth discharge path 365. The junction channel 366 discharges liquid flowing from the discharge paths 361, 363, and 365 through a discharge port 367. As shown in FIGS. 3 and 7 , the discharge port 367 opens to the bottom surface 2B of the exterior housing 2. More specifically, the discharge port 367 opens into the notch 221 of the lower panel 22. The discharge port 367 discharges the liquid that has flowed through the junction channel 366 to the outside of the exterior housing 2. This allows liquid that has flowed onto the upper surface 3A inside the exterior housing 2 through the openings 211 to 214 of the upper panel 21 and the gap between the upper panel 21 and the housing 3 to be discharged to the outside of the exterior housing 2.

[0029] [Configuration of Jog Dial] Fig. 8 is a perspective view showing the jog dial 6, push button device 7, and equalizer adjustment device 8 arranged on the housing 3. Fig. 9 is an exploded perspective view showing the jog dial 6. The jog dial 6 corresponds to the first operator, and as shown in Fig. 8, is arranged in a first arrangement section 33 provided in approximately the center of the top surface 3A. More specifically, the jog dial 6 is arranged in the first arrangement section 33 so that at least a portion of it is exposed to the top surface 3A. As shown in Figs. 8 and 9, the jog dial 6 includes a rotating body unit 61, a base unit 62, a display device 63, an adjustment dial 64, and an adjustment mechanism 65.

[0030] [Configuration of Rotating Body Unit] The rotating body unit 61 is supported by the base unit 62 so as to be rotatable around a rotation axis Rx along the Z axis. More specifically, the rotating body unit 61 can rotate infinitely clockwise and counterclockwise around the rotation axis Rx. The rotating body unit 61 has a rotating body main body 611 and a top plate 617.

[0031] The rotating body main body 611 is configured in a generally truncated cone shape with an outer diameter at the end in the +Z direction smaller than the outer diameter at the end in the -Z direction, and has a display device 63 disposed therein. The portion of the rotating body main body 611 in the +Z direction is exposed in the +Z direction relative to the upper panel 21 through the opening 211 shown in Figures 1 to 3, and receives rotation operations by the user. The rotating body main body 611 has a reduced diameter portion 612, a sheet switch 613, an elastic member 614, an opening 615, and a flow path forming portion 616.

[0032] The reduced diameter portion 612 is a ring-shaped portion extending radially inward from the +Z direction edge of the rotating body main body 611, centered on the rotation axis Rx. A sheet switch 613 and an elastic member 614 are provided on the surface of the reduced diameter portion 612 facing the +Z direction. The sheet switch 613 is configured in a ring shape and detects a user's pressing operation on the top plate 617 facing the sheet switch 613. A plurality of elastic members 614 are provided on the surface of the sheet switch 613 facing the +Z direction. The multiple elastic members 614 are arranged at equal intervals along the circumferential direction centered on the rotation axis Rx. When the top plate 617 is pressed, the sheet switch 613 is pressed by at least one of the multiple elastic members 614 in contact with the top plate 617.

[0033] The opening 615 is a circular opening whose periphery is formed by the reduced diameter portion 612. The display device 63 is placed inside the rotating body main body 611 via the opening 615. The flow path forming portion 616 is a ring-shaped portion provided inside the rotating body main body 611, and a portion of the flow path forming portion 616 overlaps with the reduced diameter portion 612 when viewed from the +Z direction. As will be described in detail later, the flow path forming portion 616 forms a flow path that discharges liquid that has entered the rotating body unit 61 through a discharge port 628 of the base unit 62, which will be described later.

[0034] The top plate 617 constitutes a portion of the upper surface of the rotating body unit 61 facing the +Z direction. The top plate 617 is attached to the rotating body main body 611 so as to cover the reduced diameter portion 612 in the +Z direction and close the opening 615. As will be described in detail later, the top plate 617 has an insertion portion 618 that is inserted into the opening 615. The top plate 617 accepts a user's pressing operation on the rotating body unit 61 in the -Z direction. Specifically, when the top plate 617 is pressed, the top plate 617 tilts relative to the rotating body main body 611, thereby pressing the sheet switch 613 via the elastic member 614. The top plate 617 is made of a translucent material. An image displayed by the display device 63, which is disposed in the -Z direction relative to the top plate 617, can be observed through the top plate 617. A gap may be formed between the top plate 617 and the reduced diameter portion 612 of the rotating body main body 611. For this reason, if rain or other liquid drips onto the acoustic device 1 from the +Z direction, the liquid may seep into the rotating body unit 61 through the gap between the rotating body main body 611 and the top plate 617. For this reason, the flow path forming portion 616 forms a flow path for discharging the liquid.

[0035] [Configuration of Base Unit] Fig. 10 is a perspective view showing the jog dial 6 without illustrating the rotator unit 61, and Fig. 11 is a plan view of the jog dial 6 without illustrating the rotator unit 61, viewed from the +Z direction. The base unit 62 is fixed to the first arrangement portion 33. The base unit 62 supports the rotator unit 61 rotatably about the rotation axis Rx, and supports the display device 63 in a non-rotatable state. The base unit 62 is configured in a substantially rectangular shape. As shown in Figs. 9 and 10 , the base unit 62 has an inner peripheral wall 621, eight rollers 622, four through holes 623, and four light-transmitting members 624.

[0036] The inner peripheral wall 621 stands cylindrically from the base unit 62. When the rotator unit 61 and the base unit 62 are combined, the inner peripheral wall 621 is disposed outside the flow path forming portion 616 of the rotator unit 61. The eight rollers 622 are disposed at approximately equal intervals along the circumferential direction centered on the rotation axis Rx. The rollers 622 rotatably support the rotator unit 61. Each of the four through holes 623 penetrates the annular base unit 62 along the Z axis. The four through holes 623 are disposed at approximately equal intervals along the circumferential direction centered on the rotation axis Rx. More specifically, the four through holes 623 are disposed on an imaginary circle connecting the eight rollers 622. Each of the four light-transmitting members 624 is fitted into a corresponding one of the four through holes 623. This prevents liquid from seeping downward through the through holes 623. In this embodiment, the number of rollers 622 is eight, and the number of pairs of through holes 623 and translucent members 624 is four, but the number of rollers 622 and the number of pairs of through holes 623 and translucent members 624 can be changed as appropriate.

[0037] FIG. 12 is a perspective view showing the jog dial 6 as viewed from the −Z direction. As shown in FIG. 12 , the base unit 62 further includes four substrates 625, four housings 626, a protrusion 627, six outlets 628, and an insertion portion 629. The substrates 625, housings 626, protrusions 627, and insertion portions 629 are provided on a bottom surface 62B of the base unit 62 facing the −Z direction, and the outlets 628 penetrate the base unit 62 along the Z axis. The four substrates 625 are arranged at approximately equal intervals in the circumferential direction centered on the rotation axis Rx. More specifically, each of the four substrates 625 is provided on the bottom surface 62B in accordance with a corresponding one of the four through-holes 623. Although not shown, a light-emitting element such as an LED (light-emitting diode) is provided on the surface of each substrate 625 facing the +Z direction. Light emitted from the light emitting element is emitted in the +Z direction relative to the base unit 62 through the through hole 623 and the light-transmitting member 624 .

[0038] The four accommodation sections 626 are cylindrical portions that accommodate corresponding substrates 625 among the four substrates 625. Specifically, each of the four accommodation sections 626 protrudes in the −Z direction from the bottom surface 62B in a generally frustum shape centered on the rotation axis Rx when viewed from the −Z direction. When the jog dial 6 is arranged in the first arrangement section 33, each accommodation section 626 is arranged in a corresponding one of four engagement sections 3331 (described later) of the first arrangement section 33. A water-repellent treatment is applied to an end surface 6261 of the accommodation section 626 in the −Z direction, and the end surface 6261 comes into contact with the water-repellent region 3334 of the corresponding engagement section 3331. This prevents liquid from seeping into the opening 3332 of the engagement section 3331.

[0039] The protrusion 627 protrudes in the −Z direction from the bottom surface 62B in a circular shape centered on the rotation axis Rx. Although not shown, the outer diameter of the protrusion 627 centered on the rotation axis Rx is the same as the outer diameter of the inner peripheral wall 621 centered on the rotation axis Rx, and the inner peripheral wall 621 and the protrusion 627 are continuous along the Z axis. When the jog dial 6 is placed in the first placement section 33, the protrusion 627 faces a second liquid guide section 334 (described later) along the Z axis. Six outlets 628 are provided at equal intervals along the circumferential direction centered on the rotation axis Rx, near the outer edge of the surface of the protrusion 627 facing the −Z direction. As will be described in detail later, each outlet 628 discharges liquid that has seeped into the interior of the rotating body unit 61. The number of outlets 628 is not limited to six and can be changed as appropriate. The insertion section 629 is provided in approximately the center of the surface of the protrusion 627 facing the −Z direction. The shape of the insertion portion 629 when viewed from the -Z direction is similar to the shapes of a first wall portion 3341 and a second wall portion 3342, which will be described later. When the jog dial 6 is placed in the first placement portion 33, the insertion portion 629 is inserted from the +Z direction between the first wall portion 3341 and the second wall portion 3342. Note that a water-repellent finish is applied to an end surface 6291 of the insertion portion 629 in the -Z direction, and the end surface 6291 comes into contact with a water-repellent region 3344 between the first wall portion 3341 and the second wall portion 3342.

[0040] 9, the display device 63 is disposed inside the rotating body unit 61. The display device 63 has a display panel such as a liquid crystal panel, and displays an image according to an image signal input from the control device. The image displayed by the display device 63 is observed through a light-transmitting top panel 617.

[0041] The display device 63 includes a housing 631, a rectifying plate 632, and a water-absorbing member 633. The housing 631 is disk-shaped and holds the display panel. The rectifying plate 632 is formed in a ring shape centered on the rotation axis Rx and is provided on the surface of the housing 631 facing the -Z direction. As will be described in detail later, the rectifying plate 632 rectifies the flow direction of liquid that has entered the jog dial 6 when the audio device 1 is positioned at an angle. The water-absorbing member 633 is formed in a ring shape centered on the rotation axis Rx and is disposed in the -Z direction relative to the rectifying plate 632. The outer diameter of the water-absorbing member 633 is smaller than the outer diameter of the rectifying plate 632. The water-absorbing member 633 absorbs liquid in the jog dial 6 when, for example, the audio device 1 is turned upside down after liquid has flowed into the jog dial 6. The water-absorbing member 633 may be any material that has water absorption properties, such as water-absorbing felt.

[0042] [Configuration of Adjustment Dial and Adjustment Mechanism] The adjustment dial 64 shown in FIGS. 8 to 12 is a dial that operates the adjustment mechanism 65. The shaft portion of the adjustment dial 64 is inserted through the opening 212 of the upper panel 21, and the knob 641 of the adjustment dial 64 is disposed above the upper panel 21. As shown in FIGS. 8 to 11 , the adjustment mechanism 65 is provided at the corner of the rectangular base unit 62 where the adjustment dial 64 is provided. The adjustment mechanism 65 adjusts the rotational resistance of the rotating body unit 61 in response to operation of the adjustment dial 64. When the knob 641 is rotated clockwise or counterclockwise as viewed from the +Z direction, the adjustment mechanism 65 operates, increasing the rotational resistance of the rotating body unit 61. When the knob 641 is rotated in the other of the clockwise and counterclockwise as viewed from the +Z direction, the adjustment mechanism 65 operates, reducing the rotational resistance of the rotating body unit 61. The above-mentioned jog operation detection board 41 detects the rotation direction and rotation angle of the rotating body unit 61, as well as the pressure state applied to the rotating body unit 61, and outputs a signal indicating the detected rotation direction, rotation angle, and pressure state of the rotating body unit 61 to the above-mentioned control device.

[0043] [Liquid Discharge Flow Path in Jog Dial] Figure 13 is a diagram showing a cross section of the jog dial 6 along the YZ plane, illustrating the discharge flow path of liquid that has flowed into the jog dial 6. As described above, in the rotating body unit 61, there is a risk of liquid such as rain entering between the reduced diameter portion 612 of the rotating body main body 611 and the top plate 617. Liquid that has entered the rotating body unit 61 through the gap between the reduced diameter portion 612 and the top plate 617 flows in the -Z direction, as shown by the dotted line in Figure 13, between the inner edge of the opening 615 of the rotating body main body 611 and the insertion portion 618 of the top plate 617 that is inserted into the opening 615. The liquid that has flowed in the -Z direction drips into the flow path forming portion 616, which partially overlaps with the reduced diameter portion 612 along the Z axis. The liquid dropped onto the flow path forming portion 616 flows to the outside of the flow path forming portion 616 when viewed from the +Z direction due to centrifugal force or the like when the rotating body unit 61 is rotated. Note that the flow path forming portion 616 may be inclined so that the liquid is positioned in the -Z direction as it goes outward.

[0044] The liquid that reaches the outer edge of the flow path forming portion 616 flows in the −Z direction through the gap between the outer edge of the flow path forming portion 616 and the inner side surfaces of the inner peripheral wall 621 and the protruding portion 627, and drips onto the inner surface of the protruding portion 627. That is, the liquid that flows in the −Z direction from the outer edge of the flow path forming portion 616 drips onto the surface of the protruding portion 627 facing the +Z direction. The liquid that drips onto the protruding portion 627 is discharged to the outside of the jog dial 6 through a discharge port 628 provided in the protruding portion 627. Specifically, the liquid discharged from the discharge port 628 is discharged into a second liquid guide portion 334 (described later) of the first arrangement portion 33. In this way, the liquid that seeps into the jog dial 6 from between the rotating body main body 611 and the top plate 617 is guided by the flow path forming portion 616 of the rotating body unit 61 to the discharge port 628 of the base unit 62 and is discharged from the discharge port 628 to the outside of the jog dial 6.

[0045] When the acoustic device 1 is installed in an inclined state, the liquid that passes between the inner edge of the opening 615 and the insertion portion 618 can flow toward the display device 63. In contrast, by providing the rectifying plate 632 on the display device 63, the liquid that flows toward the display device 63 can be made to flow along the rectifying plate 632, and thereby the liquid can be guided to the flow path forming portion 616.

[0046] [Configuration of First Arrangement Section] The first arrangement section 33 of the housing 3 is a jog dial arrangement section where the jog dial 6 is arranged in the first area 3A1. As shown in Figures 5 and 6, the first arrangement section 33 is provided in approximately the center of the top surface 3A. The first arrangement section 33 has an insertion port 331, a liquid guide section 332, and an outer inclined section 335.

[0047] The insertion opening 331 is provided in the center of the first arrangement portion 33 and penetrates the recess 31 constituting the upper surface 3A along the Z axis. A portion of the jog dial 6 in the −Z direction is inserted along the Z axis into the insertion opening 331. That is, a portion of the jog dial 6 is arranged in the −Z direction with respect to the recess 31 through the insertion opening 331.

[0048] [Configuration of Liquid Guide Portion] Liquid guide portion 332 guides the flowing liquid to first discharge path 361. Liquid guide portion 332 has a peripheral wall portion 3321 as well as a first liquid guide portion 333 and a second liquid guide portion 334. Peripheral wall portion 3321 is an upright wall that stands up from upper surface 3A and surrounds liquid guide portion 332. That is, peripheral wall portion 3321 stands up in the +Z direction at the outer periphery of first liquid guide portion 333 when viewed from the +Z direction.

[0049] [Configuration of the First Liquid Guide Section] The first liquid guide section 333 is a substantially circular recess centered on the rotation axis Rx as viewed from the +Z direction, and is recessed from the top surface 3A in the -Z direction. The rotation axis Rx substantially coincides with the center of the first arrangement section 33 as viewed from the +Z direction. The first liquid guide section 333 surrounds the jog dial 6 on the top surface 3A, as shown in FIG. 11 , for example. As viewed from the +Z direction, the inner edge of the opening 211, indicated by the dotted line in FIG. 6 , and the outer edge of the rotor unit 61, indicated by the dashed-dotted line in FIG. 6 , overlap with the first liquid guide section 333. Therefore, a portion of the liquid that has entered the exterior housing 2 through the gap between the inner edge of the opening 211 and the outer edge of the rotor unit 61 can enter the first liquid guide section 333. Furthermore, as described above, liquid that has entered the rotor unit 61 can enter the first liquid guide section 333. Surface 333A of first liquid guide portion 333 facing the +Z direction is inclined so as to be positioned in the −Z direction toward the center of first arrangement portion 33. That is, surface 333A is inclined so as to be positioned downward in the −Z direction toward second liquid guide portion 334, which is provided inside first liquid guide portion 333, as viewed from the +Z direction. Due to this inclination of first liquid guide portion 333, liquid that has entered first liquid guide portion 333 is quickly discharged from first liquid guide portion 333.

[0050] The first liquid guide portion 333 has four engaging portions 3331 and one protruding portion 3337. Each of the four engaging portions 3331 is a portion that engages with a corresponding one of the four housing portions 626 shown in FIG. 12. The four engaging portions 3331 are provided at approximately equal intervals in the circumferential direction centered on the rotation axis Rx. As shown in FIGS. 5 and 6 , each engaging portion 3331 has an opening 3332, an upright portion 3333, a water-repellent region 3334, a wall portion 3335, and a notch 3336.

[0051] The opening 3332 is formed in a generally frustum shape centered on the center CT of the first arrangement portion 33, which coincides with the rotation axis Rx. For example, a wire (not shown) that connects the substrate 625 shown in FIG. 12 to the control device is inserted through the opening 3332. As shown in FIGS. 5 and 6 , the standing portion 3333 stands in the +Z direction from the periphery of the opening 3332. When the engaging portion 3331 and the accommodation portion 626 are engaged with each other, the standing portion 3333 is disposed within the accommodation portion 626.

[0052] The water-repellent region 3334 is provided on the surface surrounding the upright portion 3333 in the first liquid guide portion 333. The water-repellent region 3334 is a region that has been subjected to a water-repellent treatment, and the end face 6261 of the accommodation portion 626 in the -Z direction comes into contact with the water-repellent region 3334. As described above, the end face 6261 is subjected to the same water-repellent treatment as the water-repellent region 3334, and therefore, when the engagement portion 3331 and the accommodation portion 626 engage, liquid is prevented from entering the opening 3332 through a gap between the water-repellent region 3334 and the end face 6261. The wall portion 3335 stands up in the +Z direction from the periphery of the water-repellent region 3334. When the engagement portion 3331 and the accommodation portion 626 engage, the wall portion 3335 is positioned outside the accommodation portion 626. This prevents liquid from entering between the water-repellent region 3334 and the end face 6261. The notch 3336 is a portion obtained by cutting out a portion in the −Y direction in the wall portion 3335. The notch 3336 is a portion that, when liquid seeps inside the wall portion 3335, discharges the liquid to the outside of the engaging portion 3331.

[0053] The protrusion 3337 is provided in a portion of the first liquid guide 333 that is sandwiched between two engaging portions 3331 located in the +Y direction. As shown in FIG. 5 , the protrusion 3337 is provided at an outer peripheral position in the first liquid guide 333 and protrudes in the +Z direction from a surface facing the +Z direction. More specifically, the protrusion 3337 is connected to the peripheral wall 321 that forms the outer peripheral edge of the first liquid guide 333. The surface of the protrusion 3337 facing the +Z direction is an inclined surface 3338 that is inclined so as to be positioned in the -Z direction as it approaches the -Y direction. The inclination angle of the inclined surface 3338 with respect to the XY plane is greater than the inclination angle of the surface 333A with respect to the XY plane. Therefore, liquid dripping onto the protrusion 3337 flows from the first liquid guide 333 to the second liquid guide 334 with increased momentum due to the inclined surface.

[0054] [Configuration of Second Liquid Guide Section] Second liquid guide section 334 is a section provided inside first liquid guide section 333, which has a substantially circular shape when viewed from the +Z direction, and is a section where insertion port 331 is formed. Second liquid guide section 334 is a recess that is recessed in the -Z direction from the inner edge of first liquid guide section 333. Surface 334A of second liquid guide section 334 facing the +Z direction is inclined so as to be positioned in the -Z direction as it approaches the -Y direction. In other words, second liquid guide section 334 is inclined so as to be positioned downward in the -Z direction as it approaches first discharge channel 361.

[0055] The second liquid guide portion 334 has a first wall portion 3341, a second wall portion 3342, and a notch 3343. The first wall portion 3341 is a wall that stands in the +Z direction from the periphery of the insertion opening 331. The second wall portion 3342 is a wall that stands in the +Z direction and is provided around the first wall portion 3341 with a predetermined gap from the first wall portion 3341 when viewed from the +Z direction. The dimension of the second wall portion 3342 in the +Z direction is approximately the same as the dimension of the first wall portion 3341 in the +Z direction. The notch 3343 is provided at the end of the second wall portion 3342 in the -Y direction. The notch 3343 discharges liquid that has seeped into the gap between the first wall portion 3341 and the second wall portion 3342 to the outside of the second wall portion 3342. The liquid discharged to the outside of the second wall portion 3342 and the liquid flowing from the first liquid guide portion 333 to the second liquid guide portion 334, together with the liquid flowing from the first liquid guide portion 333 into the first discharge path 361, are guided to the junction path 366 by the first discharge path 361. A water-repellent region 3344 that has been treated with a water-repellent coating is provided on the surface between the first wall portion 3341 and the second wall portion 3342. When the jog dial 6 is placed in the first placement portion 33, the insertion portion 629 of the base unit 62 is inserted between the first wall portion 3341 and the second wall portion 3342 from the +Z direction. A water-repellent end surface 6291 of the insertion portion 629 comes into contact with the water-repellent region 3344. This prevents liquid from entering the insertion opening 331.

[0056] [Configuration of Outer Inclined Portion] The outer inclined portion 335 is provided on the outer side of the first liquid guide portion 333 when viewed from the +Z direction. The outer inclined portion 335 includes a first inclined portion 3351, which is a portion in the −X direction from an extension line of the first discharge path 361 along the Y axis, and a second inclined portion 3352, which is a portion in the +X direction from the extension line. The first inclined portion 3351 is inclined in the −Z direction as it approaches the −X direction. That is, the first inclined portion 3351 is inclined so as to be positioned downward in the −Z direction as it approaches the second discharge path 362. Liquid dripping onto the first inclined portion 3351 through the opening 211 is discharged to the second discharge path 362 due to the inclination of the first inclined portion 3351. The second inclined portion 3352 is inclined in the −Z direction as it approaches the +X direction. That is, the second inclined portion 3352 is inclined so as to be positioned downward in the −Z direction as it approaches the fourth discharge path 364. Liquid dripping onto the second inclined portion 3352 through the opening 211 is discharged into the fourth discharge path 364 due to the inclination of the second inclined portion 3352. The flow of liquid that has entered the first arrangement portion 33 through the opening 211 of the upper panel 21 will be described in detail later.

[0057] [Configuration of Push Button Device] Fig. 14 is an exploded perspective view showing the push button device 7. The push button device 7 corresponds to the second operator and accepts a pressing operation by the user. In response to a pressing operation by the user, the push button device 7 presses switches 422A, 422B provided on the pressing operation detection board 42. The push button device 7 is provided in the corners of the top surface 3A of the housing 3 in the -X and -Y directions. As shown in Fig. 14, the push button device 7 includes two operation buttons 71, two light diffusion members 72, and one support member 73.

[0058] Each of the two operation buttons 71 is exposed on the top surface 3A and is movable in a direction from the top surface 3A to the bottom surface 3B. The two operation buttons 71 include a first operation button 71A and a second operation button 71B provided in the +Y direction relative to the first operation button 71A. Each of the operation buttons 71A, 71B is supported by a support member 73. The +Z direction portion of the first operation button 71A is exposed in the +Z direction from an opening 213A in the upper panel 21 and is operable to receive a user pressing in the -Z direction. The +Z direction portion of the second operation button 71B is exposed in the +Z direction from an opening 213B in the upper panel 21 and is operable to receive a user pressing in the -Z direction.

[0059] The two light diffusion members 72 include a first light diffusion member 72A and a second light diffusion member 72B. The first light diffusion member 72A is ring-shaped and arranged around the first operation button 71A. The first light diffusion member 72A diffuses light emitted from the first light-emitting element 421A provided on the pressing operation detection board 42 in the +Z direction. The second light diffusion member 72B is ring-shaped and arranged around the second operation button 71B. The second light diffusion member 72B diffuses light emitted from the second light-emitting element 421B provided on the pressing operation detection board 42 in the +Z direction. The support member 73 is arranged in the second arrangement portion 34 on the upper surface 3A while supporting the operation button 71 and the light diffusion member 72. The support member 73 is rectangular when viewed from the +Z direction and supports each operation button 71A, 71B while biasing them in the +Z direction. Therefore, the +Z direction portions of the operation buttons 71A and 71B are kept exposed in the +Z direction through the openings 213A and 213B.

[0060] [Configuration of Second Arrangement Section] As shown in FIGS. 5 and 6 , the second arrangement section 34 is a button arrangement section provided in a corner of the upper surface 3A in the −X and −Y directions, where the push button device 7 is arranged. That is, the second arrangement section 34 is located in the −X and −Y directions from the first arrangement section 33 across the second discharge path 362, and is located in the +Z direction from the first arrangement section 33. The second arrangement section 34 includes a first region 34A in which the first operation button 71A and the first light diffuser 72A are arranged, and a second region 34B in which the second operation button 71B and the second light diffuser 72B are arranged. The second region 34B is located in the +Y direction from the first region 34A. The support member 73 is arranged across the first region 34A and the second region 34B.

[0061] [Configuration of First Region] FIG. 15 is an enlarged perspective view of the second arrangement section 34. The first region 34A is a substantially square region with two opposing sides aligned along the X-axis and two opposing sides aligned along the Y-axis. As shown in FIG. 15 , the first region 34A includes an opening 341A, a light-transmitting member 342A, an insertion portion 343A, a shaft member 345A, four apexes 346A, four grooves 347A, and eight inclined portions 348A. The opening 341A is located in the center of the first region 34A. The opening 341A allows light emitted from the first light-emitting element 421A of the pressing operation detection board 42 to pass in the +Z direction. The opening 341A is closed by the light-transmitting member 342A. The light from the first light-emitting element 421A that passes through the opening 341A enters the first light diffusing member 72A and is diffused.

[0062] The insertion portion 343A is a boss provided in the -Y direction with respect to the opening 341A. The insertion portion 343A has a through-hole 344A that penetrates the top surface 3A along the Z axis. The shaft member 345A is disposed in the through-hole 344A so as to be movable along the Z axis. That is, the shaft member 345A is movable along the through-hole 344A. The end of the shaft member 345A in the +Z direction comes into contact with the surface of the first operation button 71A that faces the -Z direction. The end of the shaft member 345A in the -Z direction comes into contact with the switch 422A included in the pressing operation detection board 42. When the first operation button 71A is pressed in the -Z direction, the shaft member 345A presses the switch 422A. 6, when viewed from the +Z direction, the insertion portion 343A and the shaft member 345A are positioned inside the inner edge of the opening 213A, inside which the first operation button 71A is located. The inner surface of the through-hole 344A and the outer surface of the shaft member 345A are both water-repellent. This prevents liquid from flowing in the -Z direction relative to the top surface 3A through a gap between the inner surface of the through-hole 344A and the outer surface of the shaft member 345A.

[0063] 15 is a portion that extends from the periphery of opening 341A in the +Z direction with the position thereof remaining almost constant. Of the four apexes 346A, one apex 346A extends from the periphery of opening 341A in the +X direction, another apex 346A extends from the periphery of opening 341A in the -X direction, another apex 346A extends from the periphery of opening 341A in the +Y direction, and the remaining apex 346A extends from the periphery of opening 341A in the -Y direction. Note that insertion portion 343A is provided on apex 346A that extends from the periphery of opening 341A in the -Y direction.

[0064] Each of the four grooves 347A extends from the periphery of the opening 341A and is inclined with respect to the XY plane so as to be positioned in the -Z direction as it moves away from the opening 341A. Of the four grooves 347A, one groove 347A extends from the periphery of the opening 341A in the +X direction and the +Y direction, another groove 347A extends from the periphery of the opening 341A in the -X direction and the +Y direction, another groove 347A extends from the periphery of the opening 341A in the +X direction and the -Y direction, and the remaining groove 347A extends from the periphery of the opening 341A in the -X direction and the -Y direction. Each groove 347A forms a discharge path that passes between the inner edge of the opening 213A of the upper panel 21 and the outer edge of the first operation button 71A and discharges liquid that has seeped into the first region 34A from outside the exterior housing 2 to outside the first region 34A. Of the liquid discharged from such groove portion 347A, a portion of the liquid flows into discharge channel 362, and the other portion flows into discharge channel 363.

[0065] Each of the eight inclined portions 348A is a surface connecting one apex 346A to one groove 347A adjacent to that apex 346A, and is inclined with respect to the XY plane. Each inclined portion 348A guides liquid dripped onto the inclined portion 348A to the groove 347A. For example, the inclined portion 348A connecting the apex 346A extending from the periphery of the opening 341A in the +Y direction to the groove 347A extending from the periphery of the opening 341A in the +X and +Y directions guides liquid dripped onto the inclined portion 348A to the groove 347A. The same applies to the other inclined portions 348A.

[0066] [Configuration of Second Region] The second region 34B is a substantially square region with two opposing sides aligned along the X-axis and the other two opposing sides aligned along the Y-axis. The second region 34B has the same configuration as the first region 34A. That is, the second region 34B has an opening 341B, a light-transmitting member 342B, an insertion portion 343B having a through-hole 344B, a shaft member 345B, four apexes 346B, four grooves 347B, and eight inclined portions 348B.

[0067] The opening 341B is located in the center of the second region 34B and penetrates the top surface 3A along the Z axis. The opening 341B is closed by a translucent member 342B. The insertion portion 343B is a boss located in the -Y direction relative to the opening 341B, and is located on a top portion 346B extending from the periphery of the opening 341B in the -Y direction. The insertion portion 343B has a through-hole 344B that penetrates the top surface 3A along the Z axis, and a shaft member 345B is disposed within the through-hole 344B so as to be movable along the through-hole 344B. The inner surface of the through-hole 344B and the outer surface of the shaft member 345B are water-repellent. As shown in FIG. 6 , when viewed from the +Z direction, the insertion portion 343B and the shaft member 345B are located inside the inner edge of the opening 213B, within which the second operation button 71B is located.

[0068] Each of the four peaks 346B extends from the periphery of the opening 341B, similar to the four peaks 346A. Each of the four grooves 347B extends from the periphery of the opening 341B, similar to the four grooves 347B. Each groove 347B is inclined with respect to the XY plane so that it is positioned in the -Z direction as it moves away from the opening 341B. Each of the eight inclined portions 348B, similar to the eight inclined portions 348A, connects one peak 346B to one groove 347B adjacent to that peak 346B, and guides the dropped liquid to the groove 347B. Of the liquid discharged from the groove 347B, some of the liquid flows into the discharge channel 362, and the other liquid flows into the discharge channel 363.

[0069] [Function of Push Button Device] Figure 16 is a diagram showing a cross section of the acoustic device 1 along the YZ plane at the push button device 7 and the second arrangement section 34. Here, on the opposite side of the second arrangement section 34 from the push button device 7, as shown in Figure 16, a pressing operation detection board 42 attached to the bottom surface 3B is provided. The pressing operation detection board 42 has two light-emitting elements 421A and 421B and two switches 422A and 422B, and the light-emitting elements 421A and 421B and the switches 422A and 422B are provided on a surface 42A of the pressing operation detection board 42 facing in the +Z direction.

[0070] The light-emitting element 421A and the switch 422A are provided in accordance with the first region 34A. More specifically, the light-emitting element 421A is provided in accordance with the opening 341A, and the switch 422A is provided in accordance with the shaft member 345A. The light-emitting element 421B and the switch 422B are provided in accordance with the second region 34B. More specifically, the light-emitting element 421A is provided in accordance with the opening 341B, and the switch 422B is provided in accordance with the shaft member 345B. The light-emitting elements 421A and 421B are formed, for example, by LEDs. The switches 422A and 422B are formed, for example, by membrane switches.

[0071] When the first operation button 71A is pressed in the -Z direction, the shaft member 345A moves in the -Z direction by the first operation button 71A and presses the switch 422A. When the user releases the pressure on the first operation button 71A, the shaft member 345A returns to its original position due to the restoring force of the membrane switch 422A, and the first operation button 71A returns to its original position by the support member 73. When the second operation button 71B is pressed in the -Z direction, the shaft member 345B presses the switch 422B in the same way as when the first operation button 71A is pressed. Furthermore, when pressure on the second operation button 71B is released, the second operation button 71B and the shaft member 345B return to their original positions in the same way as when pressure on the first operation button 71A is released. The pressing operation detection board 42 detects the pressing operation on the first operation button 71A by determining the state of the switch 422A. The pressing operation detection board 42 detects the pressing operation of the second operation button 71B by determining the state of the switch 422B, and outputs a signal corresponding to the pressing operation of each of the operation buttons 71A, 71B to the control device.

[0072] [Configuration of Third Arrangement Section] The third arrangement section 35 in which the equalizer adjustment device 8 is arranged will be described first. The third arrangement section 35 shown in FIGS. 5 and 6 is provided at a corner in the +X direction and +Y direction on the top surface 3A of the housing 3. The third arrangement section 35 has three holes 351 penetrating the top surface 3A along the Z axis. The three holes 351 include a first hole 3511, a second hole 3512, and a third hole 3513. The shaft 83 of the first rotary volume 81A constituting the equalizer adjustment device 8 is arranged in the first hole 3511. The shaft 83 of the second rotary volume 81B constituting the equalizer adjustment device 8 is arranged in the second hole 3512. The shaft 83 of the third rotary volume 81C constituting the equalizer adjustment device 8 is arranged in the third hole 3513.

[0073] [Configuration of Equalizer Adjustment Device] As shown in FIGS. 1 and 2 , the equalizer adjustment device 8 includes three rotary volumes 81. Each rotary volume 81 corresponds to a rotary operator and accepts a rotary operation to adjust the output level of a predetermined frequency band of music. The three rotary volumes 81 include a first rotary volume 81A, a second rotary volume 81B, and a third rotary volume 81C. The first rotary volume 81A is a high-frequency band adjustment unit that adjusts the volume level of the high-frequency band of music. The high-frequency band is, for example, a frequency band equal to or higher than 4649 Hz. The second rotary volume 81B is a mid-frequency band adjustment unit that adjusts the volume level of the mid-frequency band of music. The mid-frequency band is, for example, a frequency band greater than 284 Hz and less than 4649 Hz. The third rotary volume 81C is a low-frequency band adjustment unit that adjusts the maximum volume level of the low-frequency band of music. The low-frequency band is, for example, a frequency band equal to or lower than 284 Hz. The rotary operation detection board 43 outputs a signal indicating the position of each rotary volume 81A, 81B, 81C to the control device based on the output voltage value from each rotary volume 81.

[0074] 17 is a diagram showing a cross section of the rotary volume 81 along the XZ plane. The rotary volume 81 has a variable resistor inside, the resistance value of which changes in response to rotation by the user, and the voltage value of the output voltage changes based on the rotation angle of a shaft 83, which will be described later. As shown in FIG. 17 , the rotary volume 81 includes a housing 82, a shaft 83, a knob 84, and a cap 85.

[0075] The housing 82 is attached to a support substrate SB, which is fixed to the bottom surface 3B of the housing 3, with screws SC, and is mounted on the surface 43A of the rotation operation detection substrate 43 facing the +Z direction. That is, the housing 82 is disposed inside the housing 3 and fixed to the surface 43A. The housing 82 accommodates the variable resistor. The shaft 83 is formed in a substantially cylindrical shape and is supported by the housing 82 so as to be rotatable about a rotation axis Rz along the Z axis. The shaft 83 changes the resistance value of the variable resistor according to the rotation angle about the rotation axis Rz. The shaft 83 is inserted through the opening SB1 of the support substrate SB, the hole 351 of the third arrangement portion 35, and the opening 214 of the upper panel 21 along the Z axis.

[0076] The knob 84 is connected to the shaft portion 83 and receives a user's rotation operation to rotate the shaft portion 83. The knob 84 is disposed in the +Z direction relative to the upper panel 21. The knob 84 has a ring-shaped portion 841 that is disposed within the opening 214 when the shaft portion 83 and the knob 84 are connected. The ring-shaped portion 841 corresponds to a first ring-shaped portion. The ring-shaped portion 841 is provided at the end of the knob 84 in the -Z direction and is formed in a ring shape along the circumferential direction centered on the rotation axis Rz. The ring-shaped portion 841 is disposed around the shaft portion 83, spaced a predetermined distance from the outer peripheral surface of the approximately cylindrical shaft portion 83. The outer peripheral surface 842 of the ring-shaped portion 841, the inner peripheral surface 843 of the ring-shaped portion 841, and the end surface 844 of the ring-shaped portion 841 facing the -Z direction are subjected to the same water-repellent treatment as described above. The end surface 844 connects the outer peripheral surface 842 and the inner peripheral surface 843 .

[0077] The cap 85 is configured in a ring shape centered on the rotation axis Rz and is provided around the shaft portion 83. The cap 85 has a large diameter portion 851, a small diameter portion 852, a coupling portion 853, and a connecting portion 854. The large diameter portion 851 is formed in a cylindrical shape surrounding the shaft portion 83. The large diameter portion 851 is disposed in the -Z direction with respect to the upper panel 21 and is disposed within the hole 351 of the third arrangement portion 35 when viewed from the -Z direction. The small diameter portion 852 corresponds to a second ring-shaped portion facing the ring-shaped portion 841. The small diameter portion 852 is formed in a ring shape with an outer diameter dimension smaller than that of the large diameter portion 851. The small diameter portion 852 is disposed in the +Z direction relative to the large diameter portion 851 and is disposed around the shaft portion 83 and inside the ring-shaped portion 841. When viewed from the +Z direction, small diameter portion 852 is disposed within opening 214 of upper panel 21, and the +Z direction end of small diameter portion 852 is disposed further in the +Z direction than upper panel 21. A part of the inner circumferential surface of small diameter portion 852 can come into contact with the outer circumferential surface of shaft portion 83. An outer circumferential surface 852A of small diameter portion 852 that faces inner circumferential surface 843 of ring-shaped portion 841 is subjected to the same water-repellent treatment as ring-shaped portion 841.

[0078] The connecting portion 853 extends along the XY plane and connects the large diameter portion 851 and the small diameter portion 852. The connecting portion 853 is formed in a ring shape centered on the rotation axis Rz. The connecting portion 854 is provided on the outer edge of the surface of the connecting portion 853 facing the +Z direction. The connecting portion 854 is disposed in the -Z direction with respect to the upper panel 21. The connecting portion 854 faces the periphery of the opening 214 in the bottom surface 21C of the upper panel 21. The bottom surface 21C is the surface of the upper panel 21 facing the -Z direction. The connecting portion 854 is fixed to the bottom surface 21C via a ring-shaped sealing member SM provided on the bottom surface 21C along the periphery of the opening 214. More specifically, the connecting portion 854 is connected to the surface of the sealing member SM facing the -Z direction, and the surface of the sealing member SM facing the +Z direction is connected to the bottom surface 21C of the upper panel 21. That is, the cap 85 is fixed to the bottom surface 21C of the upper panel 21, which faces the top surface 3A. The sealing member SM can be formed of an elastic member such as an O-ring, and the sealing member SM, the connecting portion 854, and the bottom surface 21C are sealed together with, for example, an adhesive.

[0079] [Waterproof Configuration of Equalizer Adjustment Device] As shown in FIG. 17 , the gap between the periphery of the opening 214 of the upper panel 21 and the cap 85 of the rotary volume 81 is sealed with a sealing member SM. This prevents liquid from entering the housing 3 through this gap. Meanwhile, the ring-shaped portion 841 of the knob 84 operated by the user and the small-diameter portion 852 of the cap 85 fixed to the upper panel 21 are both water-repellent. In particular, the inner circumferential surface 843 and the outer circumferential surface of the small-diameter portion 852 of the ring-shaped portion 841 and the cap 85, which face each other, are both water-repellent. The gap between the inner circumferential surface 843 and the small-diameter portion 852 is sized to prevent liquid from entering due to the water-repellent treatment. This prevents liquid from entering the housing 3 through the gap and through the inside of the cap 85. In this way, liquid is prevented from entering the interior of the outer casing 2, in which the electronic board 4, which is a circuit board, is located, from the outside of the outer casing 2 through the gap between the rotating volume 81 and the inner edge of the opening 214 through which the rotating volume 81 passes.

[0080] 18 is a plan view showing the top surface 3A of the housing 3 as viewed from the +Z direction, and is a diagram showing the drainage path of liquid that has seeped into the top surface 3A. Below, we will explain the drainage path of liquid that has flowed to the top surface 3A via the openings 211-213 of the upper panel 21. As described above, the infiltration of liquid into the top surface 3A via the gap between the opening 214 and the rotation volume 81 is suppressed, so we will not explain this here.

[0081] Of the liquid that has entered the interior of the exterior housing 2 through the gap between the jog dial 6 and the opening 211 shown in FIG. 8 and other figures, a portion of the liquid flows into the first liquid guide portion 333. Liquid that has passed through the gap between the opening 212 and the adjustment dial 64 also flows into the first liquid guide portion 333. The liquid that has flowed into the first liquid guide portion 333 is guided to the second liquid guide portion 334 by the inclination of the first liquid guide portion 333, as shown by arrow A11 in FIG. 18 . Furthermore, as described above, in the rotor unit 61 of the jog dial 6, the liquid that has passed through the gap between the reduced diameter portion 612 of the rotor main body 611 and the top plate 617 is guided from the outlet 628 of the base unit 62 to the second liquid guide portion 334. The liquid that has been guided to the second liquid guide portion 334 flows in the −Y direction through the second liquid guide portion 334 by the inclination of the second liquid guide portion 334, as shown by arrow A12. Then, as shown by arrow A13, the liquid that has flowed through the -Y direction portion of the second liquid guide portion 334 flows in the -Y direction through the first discharge path 361 connected to the second liquid guide portion 334 and flows into the junction path 366.

[0082] Of the liquid that has seeped into the interior of the exterior housing 2 through the gap between the jog dial 6 and the opening 211, the remaining liquid flows through the outer inclined portion 335. Of the outer inclined portion 335, the liquid that has flowed through the first inclined portion 3351 flows along the first inclined portion 3351 as indicated by arrow A21, and then flows into the second discharge path 362 as indicated by arrow A22. The liquid that has flowed into the second discharge path 362 flows through the second discharge path 362 in the −Y direction as indicated by arrow A23, and then flows into the third discharge path 363. The liquid that has flowed into the third discharge path 363 flows through the third discharge path 363 in the +X direction as indicated by arrow A3, and then flows into the junction path 366. Of the outer inclined portion 335, the liquid that has flowed through the second inclined portion 3352 flows along the second inclined portion 3352 as indicated by arrow A24, and then flows into the fourth discharge path 364 as indicated by arrow A25. Then, as shown by arrow A26, the liquid that has flowed into the fourth discharge channel 364 flows through the fourth discharge channel 364 in the −Y direction and flows into the fifth discharge channel 365. As shown by arrow A4, the liquid that has flowed into the fifth discharge channel 365 flows through the fifth discharge channel 365 in the −X direction and flows into the junction channel 366.

[0083] Liquid that seeps into the interior of the exterior housing 2 through the gap between opening 213A and the first operation button 71A of the opening 213 flows through groove 347A, as indicated by arrow A51. Liquid that seeps into the interior of the exterior housing 2 through the gap between opening 213B and the second operation button 71B flows through groove 347B, as indicated by arrow A52. Liquid that has flowed through each of grooves 347A and 347B flows into the third discharge path 363, as indicated by arrow A53. Liquid that flows into the third discharge path 363 from the second arrangement section 34 flows in the +X direction and into the junction path 366, similar to the liquid that flows into the third discharge path 363 from the second discharge path 362. Liquid that has flowed into the junction path 366 flows in the -Z direction along the junction path 366 and is discharged to the outside of the exterior housing 2 from a discharge port 367 that opens into the notch 221 of the lower panel 22.

[0084] Effects of the Embodiment The audio device 1 according to the present embodiment described above has the following effects. The audio device 1 includes an electronic board 4, a housing 3, a jog dial 6 as a first operator, and a first discharge path 361. The housing 3 has a top surface 3A and a bottom surface 3B opposite the top surface 3A, and houses the electronic board 4. At least a portion of the jog dial 6 is exposed on the top surface 3A. The first discharge path 361 is provided on the top surface 3A and discharges liquid. The housing 3 includes a first arrangement portion 33 provided on the top surface 3A and in which the jog dial 6 is disposed. The first arrangement portion 33 includes a liquid guide portion 332 that guides liquid to the first discharge path 361.

[0085] With this configuration, if liquid such as rain or drinking water seeps into the first arrangement portion 33 in which the jog dial 6 is arranged, the liquid can be quickly drained to the first drain path 361. Therefore, it is possible to prevent liquid from seeping into the housing 3, thereby improving the waterproof performance of the audio device 1.

[0086] In the acoustic device 1, the liquid guide portion 332 has a first liquid guide portion 333 and a second liquid guide portion 334. The first liquid guide portion 333 is formed in a concave shape on the upper surface 3A surrounding the jog dial 6. The second liquid guide portion 334 is provided on the inside of the first liquid guide portion 333 when viewed from the +Z direction, and is formed in a concave shape recessed downward from the inner edge of the first liquid guide portion 333. The first discharge path 361 is connected to the second liquid guide portion 334. With this configuration, the first liquid guide portion 333 and the second liquid guide portion 334 are each formed in a concave shape, and the second liquid guide portion 334 is recessed downward from the inner edge of the first liquid guide portion 333. This allows liquid dripping around the jog dial 6 to quickly flow from the first liquid guide portion 333 to the second liquid guide portion 334, and ultimately allows the liquid to be quickly discharged from the second liquid guide portion 334 to the first discharge path 361. Therefore, liquid that has entered the first arrangement portion 33 can be quickly discharged, thereby improving the waterproof performance of the audio device 1.

[0087] In the audio device 1, the housing 3 has an insertion opening 331 and a first wall portion 3341. The insertion opening 331 is provided in the second liquid guide portion 334. A portion of the jog dial 6 is inserted into the insertion opening 331 along the Z axis. The first wall portion 3341 is provided in the second liquid guide portion 334 and surrounds the periphery of the insertion opening 331. With this configuration, the first wall portion 3341 can prevent liquid that has flowed through the second liquid guide portion 334 from seeping into the insertion opening 331. Therefore, it is possible to prevent liquid from dripping onto the jog operation detection board 41, which is the electronic board 4 arranged inside the insertion opening 331.

[0088] In the acoustic device 1, the first liquid guide portion 333 is inclined so as to be positioned downward as it approaches the second liquid guide portion 334. The second liquid guide portion 334 is inclined so as to be positioned downward as it approaches the first discharge path 361. With this configuration, liquid that has dripped into the first liquid guide portion 333 can be quickly discharged to the second liquid guide portion 334, and liquid that has flowed through the second liquid guide portion 334 can be quickly discharged to the first discharge path 361. This makes it possible to improve the drainage performance of the acoustic device 1, and ultimately to improve the waterproof performance of the acoustic device 1.

[0089] The acoustic device 1 has a second discharge path 362, a third discharge path 363, and a merging path 366. The second discharge path 362 is provided outside the first arrangement portion 33 on the upper surface 3A when viewed from a position facing the upper surface 3A. That is, the second discharge path 362 is provided outside the first arrangement portion 33 on the upper surface 3A when viewed from the +Z direction. The second discharge path 362 extends along the -Y direction, which is the flow direction of liquid in the first discharge path 361, and is a groove portion through which liquid can flow. The third discharge path 363 extends intersecting with the second discharge path 362 when viewed from a position facing the upper surface 3A. The third discharge path 363 is configured to allow the liquid that has flowed through the second discharge path 362 to flow therethrough. The merging path 366 is a path through which the liquid flowing through the first discharge path 361 and the liquid flowing through the third discharge path 363 merge. The first arrangement section 33 has a first inclined section 3351. When viewed from a position facing the upper surface 3A, the first inclined section 3351 is located outside the liquid guide section 332 and is inclined so as to be positioned downward as it approaches the second discharge path 362. The first inclined section 3351 discharges liquid into the second discharge path 362.

[0090] With this configuration, liquid that drips onto the outside of the liquid guide portion 332 in the first arrangement portion 33 can be guided to the second discharge path 362 by the first inclined portion 3351, and the liquid that has flowed into the second discharge path 362 can be circulated to the junction path 366 via the third discharge path 363. This allows liquid that drips onto the first arrangement portion 33 to be quickly discharged, thereby improving the waterproof performance of the acoustic device 1.

[0091] The acoustic device 1 includes a fourth discharge path 364 and a fifth discharge path 365. When viewed from a position facing the top surface 3A, the fourth discharge path 364 is located outside the first arrangement portion 33 on the top surface 3A and on the opposite side of the first arrangement portion 33 from the second discharge path 362. The fourth discharge path 364 extends along the -Y direction, which is the direction of liquid flow in the first discharge path 361, and is a groove portion through which liquid can flow. When viewed from a position facing the top surface 3A, the fifth discharge path 365 extends, intersecting the fourth discharge path 364. Liquid that has flowed through the fourth discharge path 364 flows through the fifth discharge path 365, and the fifth discharge path 365 is connected to the junction channel 366. The first arrangement portion 33 includes a second inclined portion 3352. When viewed from a position facing the top surface 3A, the second inclined portion 3352 is located outside the liquid guide portion 332. The second inclined portion 3352 is inclined so as to be positioned downward as it approaches the fourth discharge path 364 , and discharges liquid into the fourth discharge path 364 .

[0092] With this configuration, liquid that drips onto the first inclined portion 3351 in the first arrangement portion 33 can be guided to the second discharge path 362 by the first inclined portion 3351, and liquid that drips onto the second inclined portion 3352 in the first arrangement portion 33 can be guided to the fourth discharge path 364 by the second inclined portion 3352. Then, liquid that has flowed into the second discharge path 362 can be guided to the junction path 366 via the third discharge path 363, and liquid that has flowed into the fourth discharge path 364 can be guided to the junction path 366 via the fifth discharge path 365. Therefore, liquid that has dripped onto the liquid guide portion 332, the first inclined portion 3351, and the second inclined portion 3352 can be quickly drained to the outside of the housing 3 via the junction path 366, thereby improving the waterproof performance of the acoustic device 1.

[0093] In the acoustic device 1, the housing 3 has a downwardly recessed recess 31. The top surface 3A is formed by the bottom of the recess 31. This configuration makes it easier for liquid dripping onto the top surface 3A to be received, and makes it easier to guide the liquid to the third discharge path 363 or the fifth discharge path 365. This improves the waterproof performance of the acoustic device 1.

[0094] The acoustic device 1 includes a lower panel 22 that covers the bottom surface 3B and is fixed to the housing 3, and an outlet 367 that discharges liquid that has flowed through the merged channel 366. The lower panel 22 has a notch 221, and the outlet 367 opens into the notch 221. With this configuration, liquid that has dripped onto the top surface 3A of the housing 3 can be discharged from the lower part of the housing 3.

[0095] The audio device 1 includes a push button device 7 as a second operator. The push button device 7 is exposed on the top surface 3A and includes a first operation button 71A and a second operation button 71B that are movable in a direction from the top surface 3A to the bottom surface 3B. The housing 3 includes a second arrangement section 34 that is provided on the top surface 3A and in which the push button device 7 is arranged. The second arrangement section 34 has through holes 344A and 344B that penetrate the top surface 3A, and shaft members 345A and 345B. The shaft member 345A is provided inside the through hole 344A and is movable along the through hole 344A, and the shaft member 345B is provided inside the through hole 344B and is movable along the through hole 344B. Of the electronic boards 4, the pressing operation detection board 42 includes a switch 422A that is pressed by a shaft member 345A that moves together with the first operation button 71A, and a switch 422B that is pressed by a shaft member 345B that moves together with the second operation button 71B. The outer surface of the shaft member 345A and the inner surface of the through-hole 344A are each treated with a water-repellent finish, and the outer surface of the shaft member 345B and the inner surface of the through-hole 344B are each treated with a water-repellent finish.

[0096] This configuration prevents liquid from flowing toward the pressing operation detection board 42 between the shaft member 345A pressing the switch 422A and the through-hole 344A through which the shaft member 345A passes, and between the shaft member 345B pressing the switch 422B and the through-hole 344B through which the shaft member 345B passes. This improves the waterproof performance of the audio device 1. Furthermore, the water-repellent treatment applied to the inner surfaces of the through-holes 344A and 344B and the outer surfaces of the shaft members 345A and 345B prevents liquid from entering. This eliminates the need to use sealing materials such as rubber on the movable shaft members 345A and 345B. This prevents the movement resistance of the shaft members 345A and 345B from changing due to deterioration of the sealing materials over time, thereby preventing changes in the operability of the operation buttons 71A and 71B of the push button device 7.

[0097] The audio device 1 includes an upper panel 21 that covers the top surface 3A of the housing 3 and is fixed to the housing 3, and a rotary volume 81 serving as a rotary operator. The rotary volume 81 includes a housing portion 82, a shaft portion 83, a knob 84, and a cap 85. The housing portion 82 is disposed inside the housing 3. The shaft portion 83 passes through an opening 214 in the upper panel 21 and is supported by the housing portion 82 so as to be rotatable about a rotation axis Rz. The knob 84 is coupled to the shaft portion 83 and receives an operation to rotate the shaft portion 83. The knob 84 includes a ring-shaped portion 841 that extends in the circumferential direction around the rotation axis Rz. The ring-shaped portion 841 corresponds to a first ring-shaped portion. The cap 85 is provided around the shaft portion 83 and is fixed to a bottom surface 21C of the upper panel 21 that faces the top surface 3A. The cap 85 includes a small-diameter portion 852 that faces the ring-shaped portion 841. The small diameter portion 852 corresponds to the second ring-shaped portion. The opposing surfaces of the ring-shaped portion 841 and the small diameter portion 852 are treated with a water-repellent coating. Specifically, the inner peripheral surface 843 of the ring-shaped portion 841 and the outer peripheral surface 852A of the small diameter portion 852 are both treated with a water-repellent coating.

[0098] This configuration prevents liquid from seeping into the housing 82, i.e., into the housing 3, through the gap between the opposing surfaces of the ring-shaped portion 841 and the small-diameter portion 852. This improves the waterproof performance of the audio device 1. Furthermore, the water-repellent treatment applied to the inner circumferential surface 843 of the ring-shaped portion 841 and the outer circumferential surface 852A of the small-diameter portion 852 prevents liquid from seeping in. Therefore, there is no need to use a sealing member such as rubber on the ring-shaped portion 841, which rotates with the knob 84. This prevents changes in the rotational resistance of the ring-shaped portion 841, and in turn, the rotational resistance of the knob 84, due to deterioration of the sealing member over time. This prevents changes in the operability of the rotary volume 81. Furthermore, because the upper panel 21 is fixed to the housing 3 so as to cover the top surface 3A, the arrangement portions 33-35, including the first arrangement portion 33, and the discharge path 36, including the first discharge path 361, provided on the top surface 3A can be made less noticeable. Therefore, the appearance of the audio device 1 can be improved.

[0099] The audio device 1 includes an upper panel 21 that covers the top surface 3A and is fixed to the housing 3. The upper panel 21 has an opening 211 that exposes the jog dial 6 serving as the first operator. With this configuration, as described above, the upper panel 21 is fixed to the housing 3 so as to cover the top surface 3A, making it possible to make the arrangement sections 33 to 35, including the first arrangement section 33, and the discharge path 36, including the first discharge path 361, less noticeable. This allows the audio device 1 to have a good appearance.

[0100] [Modifications of the Embodiment] The present disclosure is not limited to the above-described embodiment. In the above-described embodiment, the audio device 1 includes a jog dial 6 as a first operator and a push button device 7 as a second operator. However, this is not limiting, and the audio device 1 may include other types of operators, or the audio device 1 may include only the first operator. The first operator may be an operator different from the jog dial 6, for example, a turntable that rotates a disc such as a record. In this case, the disc serves as the operating unit of the turntable. Furthermore, for example, instead of the jog dial 6, an operating button 71 of the push button device 7 may be arranged in the opening 211, and the configuration of the first arrangement unit 33 may be applied to the second arrangement unit 34. When the push button device 7 is the first operator of the present invention and the second arrangement section 34 is the first arrangement section of the present invention, the grooves 347A, 347B provided in the second arrangement section 34 can be referred to as a liquid guide section, and at least one of the second discharge path 362 and the third discharge path 363 can be referred to as a first discharge path to which liquid is guided by the liquid guide section. Note that the push button device 7 may be configured to include either the first operation button 71A or the second operation button 71B.

[0101] In the above embodiment, the discharge path 36 includes the first discharge path 361, the second discharge path 362, the third discharge path 363, the fourth discharge path 364, the fifth discharge path 365, and the junction path 366. However, this is not limiting, and the discharge path provided in the housing 3 may be only the first discharge path 361. In this case, the first discharge path 361 may extend to an end of the housing 3, and the liquid that has flowed into the first discharge path 361 may be discharged to the outside of the housing 3.

[0102] In the above embodiment, the liquid guide portion 332 includes the first liquid guide portion 333 and the second liquid guide portion 334, which is recessed downward from the inner edge of the first liquid guide portion 333. However, this is not limiting, and the liquid guide portion 332 does not have to include the second liquid guide portion 334. In this case, it is sufficient to provide the first liquid guide portion 333 with an insertion port 331 and connect the first discharge channel 361 to the first liquid guide portion 333. Furthermore, as long as the liquid can smoothly flow from the first liquid guide portion 333 to the second liquid guide portion 334, the first liquid guide portion 333 does not have to be inclined downward toward the second liquid guide portion 334. Similarly, as long as the liquid can smoothly flow from the second liquid guide portion 334 to the first discharge channel 361, the second liquid guide portion 334 does not have to be inclined downward toward the first discharge channel 361. Furthermore, the liquid guide portion 332 may further include a liquid guide portion similar to the first liquid guide portion 333 or the second liquid guide portion 334 between the first liquid guide portion 333 and the second liquid guide portion 334 .

[0103] In the above embodiment, the second liquid guiding portion 334 is provided with the insertion opening 331 through which a portion of the jog dial 6 is inserted, and the first wall portion 3341 as a wall portion surrounding the periphery of the insertion opening 331. However, this is not limiting, and at least one of the insertion opening 331 and the first wall portion 3341 may be omitted. Furthermore, the second liquid guiding portion 334 may not be provided with the second wall portion 3342 that surrounds the first wall portion 3341 when viewed from the +Z direction.

[0104] In the above embodiment, the discharge path 36 is provided outside the first arrangement portion 33 on the upper surface 3A and includes a second discharge path 362 extending along the flow direction of the liquid in the first discharge path 361, a third discharge path 363 extending intersecting the second discharge path 362 when viewed from the +Z direction and through which the liquid flowing through the second discharge path 362 flows, and a merging path 366 through which the liquid flowing through the first discharge path 361 and the liquid flowing through the third discharge path 363 merge. However, this is not limiting, and the merging path 366 may be omitted. In this case, the liquid flowing through the first discharge path 361 and the liquid flowing through the third discharge path 363 may be separately discharged to the outside of the housing 3. Furthermore, if the liquid flowing through the first discharge path 361 and the liquid flowing through the second discharge path 362 are separately discharged to the outside of the housing 3, the third discharge path 363 may be omitted.

[0105] In the above embodiment, the discharge path 36 includes the fourth discharge path 364, which is provided outside the first arrangement portion 33 on the upper surface 3A and extends in the direction of liquid flow in the first discharge path 361, and the fifth discharge path 365, which extends intersecting the fourth discharge path 364 when viewed from the +Z direction, through which the liquid that has flowed through the fourth discharge path 364 flows, and which is connected to the merged path 366. However, this is not limiting, and the fourth discharge path 364 and the fifth discharge path 365 may be omitted. In this case, the outer portion of the liquid guide portion 332 in the first arrangement portion 33 may be inclined so as to be positioned lower as it approaches the second discharge path 362. Furthermore, the liquid that has flowed through the first discharge path 361 and the liquid that has flowed through the fifth discharge path 365 may be separately discharged to the outside of the housing 3. In this case, the fifth discharge path 365 may not be connected to the merged path 366. Furthermore, if the liquid that has flowed through the first discharge path 361 and the liquid that has flowed through the fourth discharge path 364 are discharged separately to the outside of the housing 3, the fifth discharge path 365 may not be necessary.

[0106] In the above embodiment, the first arrangement section 33 includes the first inclined portion 3351 provided on the outer side of the liquid guide section 332, and the first inclined portion 3351 is inclined so as to be positioned downward as it approaches the second discharge channel 362, thereby discharging the liquid into the second discharge channel 362. However, this is not limited to this, and the first inclined portion 3351 may be omitted. The first arrangement section 33 includes the second inclined portion 3352 provided on the outer side of the liquid guide section 332, and the second inclined portion 3352 is inclined so as to be positioned downward as it approaches the fourth discharge channel 364, thereby discharging the liquid into the fourth discharge channel 364. However, this is not limited to this, and the second inclined portion 3352 may be omitted. In other words, the portion of the first arrangement section 33 outside the liquid guide section 332 does not have to be inclined toward the second discharge channel 362 or the fourth discharge channel 364.

[0107] In the above embodiment, the top surface 3A of the housing 3 is configured by the bottom of the recess 31 that is recessed in the -Z direction from the edge of the housing 3 in the +Z direction. In other words, the top surface 3A is the surface of the recess 31 that faces the +Z direction. However, this is not limiting, and the recess 31 may be absent. In this case, the top surface 3A may be a surface that includes the edge of the housing 3 in the +Z direction.

[0108] In the above embodiment, the outlet 367 that discharges liquid to the outside of the exterior housing 2 is described as opening into the notch 221 of the lower panel 22 that constitutes the bottom surface 2B of the exterior housing 2. That is, the outlet 367 is described as opening on the bottom surface 2B of the exterior housing 2. However, this is not limited thereto, and the outlet 367 that discharges liquid that has flowed through at least the first outlet path 361 may be opened on a surface other than the bottom surface 3B. For example, the outlet 367 may be provided on at least one of the front surface 3C, rear surface 3D, left surface 3E, and right surface 3F of the housing 3 that constitutes the front surface 2C, rear surface 2D, left surface 2E, and right surface 2F. The same applies when the merged path 366 is not provided, i.e., when the liquid that has flowed through each of the outlet paths 361 to 365 is individually discharged, and outlets connected to each of the outlet paths 361 to 365 are provided.

[0109] In the above embodiment, the inner surface of the through hole 344A provided in the second arrangement portion 34 and the outer surface of the shaft member 345A provided in the through hole 344A are each subjected to a water-repellent treatment, thereby preventing liquid from flowing through the through hole 344A toward the bottom surface 3B. Furthermore, the inner surface of the through hole 344B provided in the second arrangement portion 34 and the outer surface of the shaft member 345B provided in the through hole 344B are each subjected to a water-repellent treatment, thereby preventing liquid from flowing through the through hole 344B toward the bottom surface 3B. However, this is not limiting. Alternatively, sealing members such as O-rings may be provided in contact with the inner circumferential surface of the through hole 344A and the outer circumferential surface of the shaft member 345A, or sealing members may be provided in contact with the inner circumferential surface of the through hole 344B and the outer circumferential surface of the shaft member 345B. Even in such cases, the sealing members can prevent liquid that has flowed into the through holes 344A and 344B from flowing toward the bottom surface 3B.

[0110] In the above embodiment, the rotary volume 81 serving as a rotary operator includes the knob 84 that rotates together with the shaft 83 and the cap 85 that is fixed to the bottom surface 21C of the upper panel 21. The water-repellent treatment applied to the opposing surfaces of the ring-shaped portion 841 serving as the first ring-shaped portion of the knob 84 and the small-diameter portion 852 serving as the second ring-shaped portion of the cap 85 prevents liquid from entering. However, this is not limiting, and sealing members such as O-rings may be provided in contact with the inner circumferential surface of the small-diameter portion 852 and the inner circumferential surface of the opening 214, and with the outer circumferential surface of the shaft 83. Even in this case, the sealing member can prevent liquid from flowing into the hole 351 of the housing 3 and, ultimately, from flowing below the bottom surface 3B.

[0111] In the above embodiment, the exterior housing 2 of the audio device 1 includes an upper panel 21 that covers the top surface 3A of the housing 3 and is fixed to the housing 3. However, this is not a limitation, and the upper panel 21 may be omitted. In this case, the exterior housing 2 may be configured by combining the housing 3 and the lower panel 22. Furthermore, the upper panel 21 is configured by combining a first cover 21A that covers a portion of the top surface 3A in the -X direction and a second cover 21B that covers a portion of the top surface 3A in the +X direction. However, this is not a limitation, and the upper panel 21 may be a plate-like body in which the covers 21A and 21B are integrated.

[0112] In the above embodiment, the audio device 1 is a DJ player equipped with one jog dial 6. However, the present invention is not limited to this. The audio device 1 may be a DJ mixer that mixes multiple input songs, a DJ controller that mixes multiple songs while playing them, or a DJ sampler that applies sound effects to songs being played. In other words, the present invention can be applied to any audio device that can perform audio operations on songs, such as DJ equipment.

[0113] [Summary of the Invention] The summary of the invention is as follows: [1] An acoustic device comprising: an electronic board; a housing having a top surface and a bottom surface opposite to the top surface and accommodating the electronic board; a first operator at least partially exposed on the top surface; and a first discharge path provided on the top surface for discharging liquid, wherein the housing has a first arrangement portion provided on the top surface and in which the first operator is arranged, and the first arrangement portion has a liquid guide portion for guiding liquid to the first discharge path.

[0114] According to this configuration, the first arrangement portion provided on the top surface of the housing has a liquid guide portion that guides liquid to the first discharge path. Therefore, if liquid such as rain or drinking water seeps into the first arrangement portion where the first operating element is arranged, the liquid can be quickly discharged into the first discharge path. This prevents liquid from seeping into the housing, thereby improving the waterproof performance of the audio device.

[0115] [2] The acoustic device described in [1], wherein the liquid guide portion includes a first concave liquid guide portion surrounding the first operating element and a second concave liquid guide portion disposed inside the first liquid guide portion and concave downward from the inner edge of the first liquid guide portion, and the first discharge path is connected to the second liquid guide portion. With this configuration, the first and second liquid guide portions are each formed concave, and the second liquid guide portion is concave downward from the inner edge of the first liquid guide portion. This allows liquid dripping around the first operating element to quickly flow from the first liquid guide portion to the second liquid guide portion, and ultimately to be quickly discharged from the second liquid guide portion to the first discharge path. This allows liquid that has seeped into the first arrangement portion to be quickly discharged, thereby improving the waterproof performance of the acoustic device.

[0116] [3] The acoustic device according to [2], wherein the housing has an insertion opening provided in the second liquid guide section, through which a portion of the first operating element is inserted, and a wall portion provided in the second liquid guide section, surrounding the insertion opening. With this configuration, the wall portion can prevent liquid that has flowed through the second liquid guide section from penetrating into the insertion opening. Therefore, for example, if an electronic board is placed in the insertion opening, it is possible to prevent liquid from dripping onto the electronic board.

[0117] [4] The acoustic device according to [2] or [3], wherein the first liquid guide portion is inclined so as to be positioned downward as it approaches the second liquid guide portion, and the second liquid guide portion is inclined so as to be positioned downward as it approaches the first discharge path. With this configuration, liquid dripped into the first liquid guide portion can be quickly discharged to the second liquid guide portion, and liquid that has flowed through the second liquid guide portion can be quickly discharged to the first discharge path. This can improve the drainage performance of the acoustic device, and ultimately improve the waterproof performance of the acoustic device.

[0118] [5] The acoustic device according to any one of [1] to [4], comprising: a second discharge channel provided outside the first arrangement section on the upper surface as viewed from a position facing the upper surface, extending in a direction in which liquid flows in the first discharge channel and through which liquid can flow; a third discharge channel extending intersecting the second discharge channel as viewed from the facing position and through which liquid that has flowed in the second discharge channel flows; and a merging channel through which the liquid flowing in the first discharge channel and the liquid flowing in the third discharge channel merge; wherein the first arrangement section has a first inclined section located outside the liquid guide section as viewed from the facing position and inclined downward as it approaches the second discharge channel, and the first inclined section discharges liquid into the second discharge channel. With this configuration, liquid dripped outside the liquid guide section in the first arrangement section can be guided to the second discharge channel by the first inclined section, and liquid that has flowed in the second discharge channel can be circulated to the merging channel via the third discharge channel. This allows liquid that drips onto the first arrangement portion to be quickly drained, thereby improving the waterproof performance of the audio device.

[0119] [6] The acoustic device described in [5] comprises: a fourth discharge channel, which is provided on the outer side of the first arrangement portion on the upper surface and on the opposite side of the first arrangement portion from the second discharge channel when viewed from the opposing position, extending along the flow direction of liquid in the first discharge channel and through which liquid can flow; and a fifth discharge channel, which extends and intersects with the fourth discharge channel when viewed from the opposing position, through which liquid that has flowed through the fourth discharge channel flows and which is connected to the merging channel; wherein the first arrangement portion has a second inclined portion which is located outside the liquid guide portion when viewed from the opposing position and is inclined so as to position downward as it approaches the fourth discharge channel, and wherein the second inclined portion discharges liquid into the fourth discharge channel.

[0120] With this configuration, liquid that drips onto the first inclined portion in the first arrangement portion can be guided to the second discharge path by the first inclined portion, and liquid that drips onto the second inclined portion in the first arrangement portion can be guided to the fourth discharge path by the second inclined portion. Liquid that flows into the second discharge path can then be guided to the merging path via the third discharge path, and liquid that flows into the fourth discharge path can then be guided to the merging path via the fifth discharge path. Therefore, liquid that drips onto the liquid guide portion, the first inclined portion, and the second inclined portion can be quickly drained to the outside of the housing via the merging path, thereby improving the waterproof performance of the acoustic device.

[0121] [7] The acoustic device according to [5] or [6], wherein the housing has a recess that is recessed downward, and the top surface is formed by the bottom of the recess. This configuration makes it easier for liquid dripping onto the top surface to be received and for the liquid to be easily guided to the third discharge path or the fifth discharge path. This improves the waterproof performance of the acoustic device.

[0122] [8] The acoustic device according to any one of [5] to [7], further comprising: a lower panel that covers the bottom surface and is fixed to the housing; and an outlet that discharges liquid that has flowed through the merging channel, the lower panel having a notch, and the outlet opening into the notch. With this configuration, liquid that drips onto the upper surface of the housing can be discharged from the lower part of the housing.

[0123] [9] An acoustic device according to any one of [1] to [8], comprising a second operator exposed on the top surface and movable in a direction from the top surface to the bottom surface when pressed, the housing having a second arrangement portion provided on the top surface in which the second operator is arranged, the second arrangement portion having a through hole penetrating the top surface and an axis member provided inside the through hole and movable along the through hole, the electronic board having a switch pressed by the axis member that moves together with the second operator, and the outer surface of the axis member and the inner surface of the through hole each having a water-repellent finish.

[0124] This configuration prevents liquid from flowing between the shaft member that presses the switch provided on the electronic board and the through-hole through which the shaft member passes and toward the electronic board. This improves the waterproof performance of the audio device. Furthermore, the water-repellent treatment applied to the inner surface of the through-hole and the outer surface of the shaft member prevents liquid from entering, eliminating the need to use a sealing member such as rubber on the shaft member, which is a movable member, to prevent liquid from entering. This prevents the movement resistance of the shaft member from changing due to deterioration of the sealing member over time, thereby preventing changes in the operability of the second operating element.

[0125]

[10] An acoustic device according to any one of [1] to [9], comprising: an upper panel covering the top surface and fixed to the housing; and a rotary operator, wherein the rotary operator comprises: a housing portion disposed inside the housing; a shaft portion inserted through an opening in the upper panel and supported on the housing portion so as to be rotatable about a rotation axis; a knob connected to the shaft portion and configured to receive an operation for rotating the shaft portion; and a cap provided around the shaft portion and fixed to a surface of the upper panel facing the top surface, wherein the knob has a first ring-shaped portion extending in a circumferential direction about the rotation axis; and the cap has a second ring-shaped portion facing the first ring-shaped portion, and wherein the surfaces of the first ring-shaped portion and the second ring-shaped portion facing each other are water-repellent.

[0126] This configuration prevents liquid from penetrating into the housing, i.e., into the housing, through the gap between the opposing surfaces of the first and second ring-shaped portions. This improves the waterproof performance of the audio device. Furthermore, because the water-repellent finish applied to the first and second ring-shaped portions prevents liquid from penetrating, there is no need to use a sealing member such as rubber on the first ring-shaped portion, which rotates with the knob. This eliminates the need to change the rotational resistance of the first ring-shaped portion, and ultimately the knob, due to deterioration of the sealing member over time. This prevents changes in the operability of the rotary control. Furthermore, because the upper panel is fixed to the housing so as to cover the top surface, the first arrangement portion and first exhaust channel on the top surface can be made less noticeable. This improves the audio device's appearance.

[0127]

[11] The acoustic device according to any one of [1] to [9], further comprising an upper panel that covers the upper surface and is fixed to the housing, the upper panel having an opening that exposes the first operating element. According to this configuration, as with the above, the upper panel is fixed to the housing so as to cover the upper surface, making the first arrangement portion and the first discharge path provided on the upper surface less noticeable. This improves the appearance of the acoustic device.
