FIG. 3 shows an external configuration diagram of the device of the present invention. FIG. 4 shows an exploded perspective view of this apparatus. In these drawings, the device A of the present invention is applied to a bass sound unit.
The bass sound unit A includes a front panel 1 provided with an infrared transmissive window W and an operation unit 11, and a body 2 disposed on the back side of the front panel 1 with a cover C interposed therebetween. The front panel 1 is provided with an operation portion 11 provided with an operation switch SW (described later) in the center, and a sealed speaker SP is separated on the left and right sides thereof. It is arranged. Reference numeral 17 denotes a speaker exposure window provided on the front panel 1 for exposing the sealed speaker SP.

  FIG. 1 is a diagram showing an example of the structure of a circuit board that forms the main part of the device of the present invention.

  In the figure, the circuit board B is mounted with the infrared LED lamp L facing inward of the body 2 at the center of the main circuit board B2 on which the electrode part B21 of the switch SW and the like are mounted. Inside, a curved reflector R that reflects the irradiation light from the infrared LED lamp L is provided, and the reflected light from the reflector R is from a notch B3 formed around the infrared LED lamp L on the main circuit board B2. The light is reflected toward the infrared transmission window W provided on the front panel 1.

  In addition, an infrared transmissive window W is formed at an appropriate position of the front panel 1, and the infrared transmissive window W has a notch 12 in a range of the front panel 1 where infrared rays from the infrared LED lamp L are irradiated. The light-transmitting plate 13 is fitted into the notch 12. The light emitting unit circuit board B1 and the main circuit board B2 are electrically connected by the wiring l.

  In such a structure, the circuit board B can be configured such that the light emitting unit circuit board B1 and the main circuit board B2 can be configured on the same circuit board. Without impairing the operability of the switch SW, the thickness of the entire apparatus A can be reduced by preventing the infrared transmission window W from protruding forward.

  FIG. 2 shows the structural features of the inventive device proposed at the same time.

  The circuit board B shown in this figure has a main circuit board B2 on which circuit components such as a light emitting part circuit board B1 on which infrared LED lamps L1 and L2 are mounted and an electrode part B21 of a switch SW are mounted on the infrared transmission window W side. The light emitting unit circuit board B1 is disposed so as to penetrate the central part of the main circuit board B2 and to be retracted inward of the body 2. The light emitting unit circuit board B1 and the main circuit board B2 are They are connected by wiring l. B4 is a support for supporting the main circuit board B2 in the body 2.

And an infrared passage hole 16 through which infrared rays pass.

  An infrared transmission window W is configured at an appropriate position of the front panel 1 so as to correspond to the infrared passage hole 16. The infrared transmission window W is configured to transmit infrared rays from the infrared LED lamps L 1 and L 2 in the front panel 1. A cutout portion 12 is formed in the irradiation range, and a translucent plate 13 is fitted into the cutout portion 12.

  Further, the infrared LED lamps L1 and L2 are mounted so as to be inclined in different directions so that their optical axes intersect with each other, thereby reducing the height when the LED lamp is mounted, and the range in which the infrared rays reach Is wide.

  With such a structure, the thickness of the entire apparatus A is reduced by preventing the infrared transmission window W from protruding forward without impairing the operability of the switch SW provided in the operation unit 11. FIG. 5 is a diagram (schematic system diagram) for explaining how the system is used when the present invention is applied to a bass sound unit.

In this system, a bass sound unit A is installed in the bathroom, a power supply unit U is installed on the ceiling of the bathroom, and the audio equipment S (stereo speakers) having a remote control receiver Sa outside the bathroom such as a dressing room or living room. When a switch SW provided on the operation unit 11 of the bass sound unit A is operated in the bathroom, infrared rays are transmitted through the window glass G in the dressing room or the living room. Reaching the installed audio device S,
The audio device S is operated by remote control.

  The bass sound unit A and the power supply unit U are connected by a power supply line LA and an audio line LB. The bass sound unit A receives power from the power supply unit U through the power supply line LA, and the audio equipment S through the power supply unit U. The sound from is supplied. That is, the power supply unit U supplies power and relays audio.

  According to such a configuration, when the operation unit 11 of the bass sound unit A is operated, infrared rays reach the audio device S, and in response thereto, the audio device S performs an instructed process. It is sent to the bass sound unit A through the power supply unit 2 and output from the speaker SP.

  In addition, if the bass sound unit A is provided with only the speaker SP and outputs only sound, the video when the audio device S is a television device can be seen through the glass G, and the bass sound unit A As a result, the design is improved.
