DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows an example in which a wireless communication device 150 according to the present invention is used in a performance system 1. The performance system 1 shown in Fig. 1 includes an effector device 100, an electric guitar 200 which is an electric musical instrument (i.e., a musical instrument), and a guitar amplifier 300. The electric guitar 200 is provided with a guitar strap 210 for hanging on the shoulder. An effector control device 10 is provided between the guitar strap 210 and the electric guitar 200.
[0010] The electric guitar 200 is connected to the effector device 100 by wire via a guitar cable 220. The effector device 100 has an effect section 120 which is connected to an electric signal input section 110, an electric signal output section 130, and a control signal input section 140. The electric signal input section 110 is connected to the guitar cable 220, and receives an electric signal (audio signal) from the electric guitar 200. The input electric signal is given various effects such as wow and distortion by the effect section 120, and is output via the electric signal output section 130. The electric signal output section 130 is connected to a guitar amplifier 300 by wire. The electric signal output from the electric signal output section 130 is output as sound from the guitar amplifier 300.
[0011] The effect section 120 imparts an effect to the electrical signal input from the electrical signal input section 110 in accordance with the degree of the effect adjusted based on the control signal from the control signal input section 140. The control signal input section 140 is connected by wire to an output terminal 154 (described later) of the wireless communication device 150. The wireless communication device 150 can receive an output signal transmitted from the effector control device 10 via a wireless communication section 42a (described later). The degree of the effect is adjusted arbitrarily by the effector control device 10.
[0012] When a player of the electric guitar 200 puts the electric guitar 200 on his shoulder with the guitar strap 210 while playing, for example by pushing the electric guitar 200 downward to apply tension to the guitar strap 210, the effector control device 10 outputs a control signal indicating the degree of the effect corresponding to the tension on the guitar strap 210. The wireless communication device 150 receives a control signal from the effector control device 10 and outputs a signal based on the signal from the effector control device 10 to the control signal input section 140 of the effector device 100. Since the effector control device 10 outputs a control signal corresponding to the tension on the guitar strap 210, for example, it is possible to perform control such as increasing the degree of the effect when the electric guitar 200 is pushed downward strongly and decreasing the degree of the effect when the electric guitar 200 is pushed downward weakly.
[0013] 2 and 3, the wireless communication device 150 is provided with a resin case 15 and is provided in a substantially rectangular box shape. The wireless communication device 150 is provided with two foot switches 151 (first foot switch 151-1, second foot switch 151-2) exposed from the upper surface of the resin case 15. The upper surface of the resin case 15 of the wireless communication device 150 is provided with a setting knob 152 (first setting knob 152-1, second setting knob 152-2) and a plurality of setting switches 153 (first setting switch 153-1, second setting switch 153-2).
[0014] In the following description of wireless communication device 150, the foot switch 151 side will be referred to as the near side or front side, the opposite side as the far side or rear side, the side where setting knob 152 and setting switch 153 are provided as the upper side, and the opposite side as the lower side. Also, when viewing wireless communication device 150 from the near side, the left side (the side where first foot switch 151-1 is provided) will be referred to as the left, and the right side (the side where second foot switch 151-2 is provided) will be referred to as the right.
[0015] An indicator unit 157 is provided between the first setting knob 152-1 and the first setting switch 153-1 on the left side and the second setting knob 152-2 and the second setting switch 153-2 on the right side. The indicator unit 157 has a plurality of LEDs arranged in the front-rear direction, which light up according to various output levels, allowing the output levels to be visually confirmed. Two output terminals 154 (a first output terminal 154-1 and a second output terminal 154-2) are provided on the rear side surface of the wireless communication device 150. An AC power terminal 155 is provided between the two output terminals 154.
[0016] The setting knob 152 functions both as a volume for switching the power ON / OFF and adjusting the output. Four setting switches 153 are provided on each side (eight in total), and are assigned as switches for switching the TRS arrangement and converting polarity. A control signal received from the effector control device 10 is output from an output terminal 154 according to the settings of the setting knob 152 and the setting switches 153.
[0017] The wireless communication device 150 is used while being placed on the floor or the like, and the output from the output terminal 154 (first output terminal 154-1, second output terminal 154-2) can be switched by stepping on the two foot switches 151 (first foot switch 151-1 or second foot switch 151-2) with the foot to turn them ON / OFF. Specifically, when the first foot switch 151-1 is turned ON, a signal according to the settings of the first setting knob 152-1 and the first setting switch 153-1 is output from the first output terminal 154-1. When the second foot switch 151-2 is turned ON, a signal according to the settings of the second setting knob 152-2 and the second setting switch 153-2 is output from the second output terminal 154-2. It is also possible to turn ON both the first foot switch 151-1 and the second foot switch 151-2 to output signals from both the first output terminal 154-1 and the second output terminal 154-2.
[0018] The resin case 15 of the wireless communication device 150 includes an upper case 15a and a lower case 15b. The upper case 15a is in the shape of a generally long rectangular box with the bottom omitted. The lower case 15b is in the shape of a generally plate (see also FIG. 3). The upper case 15a is provided with a recess 15a1 extending from the upper surface area where the setting knob 152 and the setting switch 153 are provided to the left and right side areas. When viewed from above, the recess 15a1 is in the shape of a generally long rectangle that is slightly longer in the front-rear direction, and when viewed from the left and right side areas, it is in the shape of a generally trapezoid that narrows downward.
[0019] The upper case 15a and the lower case 15b of the resin case 15 are manufactured by injection molding of resin. Aluminum decorative covers 158 are provided in the left and right recesses 15a1 of the upper case 15a so as to cover the left and right side surfaces of the left and right setting knobs 152 and the setting switches 153 from around them while exposing the left and right setting knobs 152 and the setting switches 153.
[0020] The foot switch 151 has a generally cylindrical head, and a pressing portion 151a pressed by the foot is exposed from a front upper surface 15a5, which is the upper surface of the upper case 15a on the front side of the recess 15a1. In the resin case 15, the front upper surface 15a5 on which the foot switch 151 is provided is inclined so that the front side is downward (see also Figs. 8 and 9). On the other hand, a rear upper surface 15a6 on the rear side of the recess 15a1 is generally parallel to a lower surface 15b1 of the lower case 15b, and three LEDs 156 are provided thereon.
[0021] As shown in Fig. 4, in the resin case 15, the upper case 15a and the lower case 15b are fixed by the screw members 30, which are six flat head screws. In addition, the two foot switches 151 are fixed to a sheet metal support member 50. The sheet metal support member 50 is fixed to the lower case 15b by the screw members 31, and is housed in the resin case 15. The details of the fixation by the screw members 30, 31 will be described later. The screw members may be expressed as fastening members, fixing members, etc.
[0022] As shown in FIG. 5, six cylindrical bosses 15a2 are erected downward inside the upper case 15a, three on each edge in the front-rear direction. The bosses 15a2 are provided with female threads, and the screw members 30 (see FIG. 4) are screwed into the bosses 15a2. Two circular openings 15a3 are provided in the front upper surface 15a5 of the upper case 15a. The pressing portion 151a of the foot switch 151 is exposed through the openings 15a3. An engagement protrusion 15a4 protruding downward is provided on the inner surface of the upper case 15a between the two openings 15a3. The engagement protrusion 15a4 is substantially plate-shaped with a long front-rear direction with the plate surface facing the left-right direction, and the front end and rear end are short and protrude in the left-right direction. In other words, the engagement protrusion 15a4 is provided in a substantially plate-like shape that is substantially I-shaped in a plan view.
[0023] An operation circuit board 40, on which a setting knob 152 and a setting switch 153 are provided and exposed from the upper surface of the recess 15a1, is fixed by screws inside the upper case 15a. A power supply circuit board 41 is provided below the operation circuit board 40. The power supply circuit board 41 is provided with an output terminal 154 and an AC power supply terminal 155, and is fixed to the upper case 15a by screws.
[0024] As shown in FIG. 6, the sheet metal support member 50 supporting the two foot switches 151 is made of one sheet metal material and is generally U-shaped with the open side facing downward when viewed from the front-rear direction. The sheet metal support member 50 includes a top plate 51 to which the foot switch 151 is fixedly attached, and two side plates 52 extending downward from both the left and right ends of the top plate 51. A notch 52c is provided at the lower end of each side plate 52. A bent portion 52a that is bent inward is provided at the portion of the lower end of the side plate 52 that is rearward of the notch 52c. The bent portion 52a is provided so that the plate surface, i.e., the upper surface 52a1 and the lower surface 52a2 of the bent portion 52a face the vertical direction. Each bent portion 52a is provided with a female screw 52a3.
[0025] In the front portion of the notch 52c in the side plate 52, a lower edge surface 52b is provided as the lower surface of the portion of the side plate 52 that has not been subjected to processing such as bending. Here, as shown in Fig. 9, the lower surface 52a2 of the bent portion 52a is located above the lower edge surface 52b. Also, as shown in Fig. 4, the front edge surface 52d of the side plate 52 is linearly continuous in the vertical direction, but the rear edge surface 52e bulges out so that the bent portion 52a has a predetermined size.
[0026] In addition, the front edge of the top plate 51 is provided with a reinforcing bent portion 51a that is bent downward at a right angle. The reinforcing bent portion 51a is disposed between the two side plates 52, and increases the rigidity of the top plate 51 against a bending force in the downward direction. A reinforcing bent portion can also be provided on the rear edge of the top plate 51. However, when a reinforcing bent portion is provided on the rear edge of the top plate 51, the height of the sheet metal support member 50 needs to be increased in consideration of interference with the housing 151b of the foot switch 151 and interference with internal components (such as the setting switch 153), which may result in an increase in the size of the device.
[0027] Further, an engagement slot 51b that is long in the front-rear direction is provided between the two foot switches 151 fixed to the top plate 51. As shown in Fig. 8, an engagement protrusion 15a4 of the upper case 15a is inserted into and engaged with the engagement slot 51b. As shown in Fig. 5, by inserting the engagement protrusion 15a4 into the engagement slot 51b, the left and right edges of the substantially I-shaped engagement protrusion 15a4 come into sliding contact with the engagement slot 51b in a left-right manner, and the sheet metal support member 50 is positioned in the left-right direction with respect to the upper case 15a when assembling the wireless communication device 150.
[0028] As shown in FIG. 8, the top plate 51 is inclined so that the front side is downward. The angle at which the top plate 51 is inclined is approximately parallel to the front upper surface 15a5 of the upper case 15a. Here, the axis CL1 of the foot switch 151 is perpendicular to the plate surface of the top plate 51. Therefore, the pressing portion 151a of the foot switch 151 is provided facing the front side. In this embodiment, the angle θ at which the top plate 51 is inclined from the horizontal plane is set to about 10 degrees. This allows the user to rotate the toe with the heel as a fulcrum to depress the foot switch 151 well.
[0029] As shown in FIG. 7, the lower case 15b is provided in a substantially plate-like shape. A plurality of ribs 15b3 long in the front-rear direction are arranged in the left-right direction on an inner surface 15b5 of the lower case 15b. A total of six screw holes 15b2 are provided in the left and right edges of the inner surface 15b5 (upper surface of the lower case 15b) of the lower case 15b, three in the front-rear direction, so as to face each other in the left-right direction. The screw holes 15b2 are provided corresponding to the bosses 15a2 of the upper case 15a. The upper case 15a and the lower case 15b are fixed by a plurality of screw members 30 (see FIG. 4) screwed into the female threads of the bosses 15a2 through the respective screw holes 15b2. As shown in FIG. 3, the screw holes 15b2 are countersunk on the lower surface 15b1 side of the lower case 15b. Of the six screw holes 15b2, circular rubber feet 32 are attached to the four screw holes 15b2 (screw members 30) at the four corners on the underside 15b1 side.
[0030] A substantially rectangular annular wall portion 15b6 is provided on the outer periphery of the lower case 15b. When the lower case 15b is combined with the upper case 15a, the annular wall portion 15b6 is located inside the upper case 15a, and a plurality of ribs 15b61 on the outer wall surface slide against the inner periphery of the side wall of the upper case 15a, positioning the lower case 15b relative to the upper case 15a.
[0031] On the inner side surface 15b5 of the lower case 15b (the upper surface of the lower case 15b, in other words, the inner surface of the bottom plate of the resin case 15), two bosses 15b4, one on each side, are provided facing each other in the left-right direction near the front side. The bosses 15b4 are provided so as to protrude from the inner side surface 15b5, and are circularly concave when viewed from the lower surface 15b1 side (see FIG. 3). The bosses 15b4 are provided with a screw hole 15b41. The sheet metal support member 50 is fixed to the lower case 15b by the screw member 31 (see FIG. 4) screwing into the female thread of the bent portion 52a of the sheet metal support member 50 through the screw hole 15b41 (see also FIG. 8). As shown in FIG. 9, the lower surface 52a2 of the bent portion 52a is in face contact with the upper surface of the boss 15b4. A lower edge surface 52b of the side plate 52 of the sheet metal supporting member 50, which is located below the lower surface 52a2 of the bent portion 52a, is in face-to-face contact with an inner side surface 15b5 of the lower case 15b.
[0032] When the foot switch 151, which has an inclined axis CL1, is stepped on by a foot, a large load is applied to the front portion of the side plate 52. However, since the sheet metal support member 50 is supported by the surface contact between the lower surface 52a2 of the bent portion 52a and the upper surface of the boss 15b4, damage to the lower case 15b can be reduced. Since the lower surface of the bent portion 52a and the lower edge surface 52b are provided at different heights, part of the load when the foot switch 151 is stepped on by a foot can also be received by the inner surface 15b5 that is in surface contact with the lower edge surface 52b. Therefore, the load when the foot switch 151 is stepped on by a foot is further distributed, and damage to the lower case 15b can be further reduced. Since the bent portion 52a is bent toward the inside of the wireless communication device 150, the size of the device can be made more compact than when it is bent toward the outside.
[0033] Further, a wireless communication circuit board 42 is fixed to the lower case 15b by screws. The wireless communication circuit board 42 is provided with a wireless communication unit 42a, which is a wireless module, and is a board including the wireless communication unit 42a. The operation circuit board 40 and power supply circuit board 41 provided in the upper case 15a and the wireless communication circuit board 42 and foot switch 151 provided in the lower case 15b are electrically connected by a flat cable 45, part of which is shown in the figure, or the like.
[0034] As shown in Fig. 10, the wireless communication unit 42a of the wireless communication circuit board 42 is disposed outside the area surrounded by the top plate 51 and the two side plates 52 of the sheet metal support member 50. The area surrounded by the top plate 51 and the two side plates 52 is indicated by a hatched area S1 in Fig. 8. In other words, the positional relationship between the sheet metal support member 50 and the wireless communication unit 42a is set so that the wireless communication unit 42a is visible in a plan view as shown in Fig. 10. In further other words, the positional relationship between the sheet metal support member 50 and the wireless communication unit 42a is set so that the wireless communication unit 42a is visible in any of the up-down, left-right, and front-back directions.
[0035] Therefore, the output signal from the effector control device 10 hardly interferes with the sheet metal support member 50 in any of the front-rear, up-down, and left-right directions, and can be received well by the wireless communication unit 42a. For example, even in front of the wireless communication unit 42a, radio waves can pass between the two side plates 52 below the top plate 51 of the sheet metal support member 50. Note that the resin case 15 is made of resin, and the operation circuit board 40 and power supply circuit board 41 are also made of resin, so there is almost no hindrance to reception of the wireless communication unit 42a.
[0036] As described above, according to an embodiment of the present invention, wireless communication device 150 includes resin case 15, sheet metal support member 50 that is housed in resin case 15 and supports foot switch 151 exposed from resin case 15, and wireless communication unit 42a that is housed in resin case 15.
[0037] This allows the sheet metal support member 50 to withstand the force of stepping on the foot switch 151, providing sufficient rigidity for functioning the foot switch 151. Furthermore, the wireless communication unit 42a is housed in the resin case 15, which has good communication properties, making it easy to ensure the necessary wireless communication performance.
[0038] Moreover, the sheet metal support member 50 has a top plate 51 to which the foot switch 151 is attached and two side plates 52 extending from the top plate 51, and the wireless communication unit 42a is disposed outside an area S1 surrounded by the top plate 51 and the two side plates 52. This reduces interference between the radio waves received by the wireless communication unit 42a and the sheet metal support member 50, thereby further improving wireless communication performance.
[0039] Moreover, the side plate 52 has a bent portion 52a at its lower end, and a lower surface 52a2 of the bent portion 52a is located above a lower edge surface 52b of the side plate 52. This allows the screw member 31 to be provided so that the lower surface side of the boss 15b4 to which the screw member 31 for fixing the sheet metal support member 50 to the lower case 15b is attached is concave while the sheet metal support member 50 is received in face-to-face contact therewith, so that the screw member 31 does not protrude from the lower surface 15b1 of the lower case 15b.
[0040] Furthermore, a boss 15b4 is provided on the inner surface of the bottom plate of the resin case 15 so as to protrude and come into contact with the lower surface of the bent portion 52a, and the bent portion 52a and the boss 15b4 are fixed by a screw member 31. This makes it possible to fix the sheet metal supporting member 50 to the resin case 15 so that the load applied to the sheet metal supporting member 50 can be received by the surface abutment between the bent portion 52a and the boss 15b4.
[0041] In addition, the tabletop 51 is inclined so that the front side is downward. This allows the foot switch 151 to be provided so that the axis CL1 of the foot switch 151 is inclined toward the front side, making it easy to press the foot.
[0042] Additionally, the top plate 51 has a reinforcing bent portion 51a that is bent so as to be disposed between the two side plates 52. This can further increase the rigidity of the sheet metal supporting member 50.
[0043] Furthermore, the resin case 15 includes an upper case 15a and a lower case 15b, and the wireless communication circuit board 42 including the wireless communication unit 42a is fixed to the lower case 15b side. The other boards (the operation circuit board 40 and the power supply circuit board 41) are fixed to the upper case 15a side. This allows the wireless communication circuit board 42 to be arranged separately from the other boards (the operation circuit board 40 and the power supply circuit board 41), making it easy to arrange the wireless communication circuit board 42 in any position so as to ensure good communication performance.
[0044] Further, the sheet metal support member 50 is provided with an engagement long hole 51b long in the front-rear direction, and the upper case 15a is provided with an engagement protrusion 15a4 that engages with the engagement long hole 51b. This allows the sheet metal support member 50 to be easily positioned during assembly. In this embodiment, when the sheet metal support member 50 is engaged with the resin case 15, the engagement protrusion 15a4 provided on the inside of the resin case 15 is engaged with the engagement long hole 51b provided on the top plate 51 of the sheet metal support member 50. This allows the sheet metal support member 50 to be engaged with the resin case 15 with a good clearance, so that the foot switch 151 and the resin case 15 are prevented from rubbing against each other when the foot switch 151 is stepped on, which would cause damage to the resin case 15. In this embodiment, the reinforcing bent portion 51a is provided, so that strength is ensured even if the top plate 51 is provided with the engagement long hole 51b. In this embodiment, positioning by the inside of the resin case 15 and the outside of the sheet metal support member 50 is not adopted. This is because bending the sheet metal support member 50 involves precision issues.
[0045] Moreover, the wireless communication device 150 includes an output terminal 154 that connects to the effector device 100, and the wireless communication unit 42a receives a signal from the effector control device 10 provided on the electric guitar 200, which is a musical instrument, and the output terminal 154 outputs a signal based on the signal from the effector control device 10 to the effector device 100. This makes it possible to provide a performance system 1 that allows the effector device 100 to be controlled from any position within a predetermined range.

These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
