Description

The present invention includes a speaker device with incorporated lamp to the light receiver, and a Ruoto sound system including the same.

  In recent years, the relaxation effect of bathing has been reviewed, and bathing while listening to music may be required to enjoy a relaxed feeling. In addition, there is a demand for listening to information on society, economy, sports, etc. even when taking a bath, and it is often performed to equip a bathroom with an acoustic system (for example, see Patent Document 1).

Therefore, the speaker is embedded in the ceiling of the bathroom or inserted into the inspection port. In addition, a remote controller (hereinafter simply referred to as “remote controller”) that performs power on / off, volume adjustment, channel selection, etc., is connected to the hot water supply device body via a cable and is used to remotely operate the hot water supply device. The remote controller is also used as a remote controller, and the remote controller is attached to a panel forming a ceiling or wall. Therefore, the bather can select and listen to music, programs, etc. according to his / her preference and request separately from the operation on the hot water supply device body by operating the remote controller.
Japanese Patent No. 3477435

  However, in the case of a conventional bathroom acoustic system as described in Patent Document 1, since the controller is in a fixed form in which the controller is embedded in the side wall of the bathroom, the controller can reach the hands of the person immersed in the bathtub immediately. It only has to be provided at the position, but when it is far away, it is necessary to get out of the bathtub and operate.

  Therefore, it is conceivable that the remote controller for operating the audio device or the like is a wireless hand-held type, but in that case, the hole for attaching the receiver that receives the signal from the remote control to the panel surface is the hole for mounting the speaker It is necessary to provide it separately. Therefore, an opening work for attaching the light receiver and a complicated work for attaching the light receiver to the hole are required, and the work cost increases.

  Further, not only the bathroom acoustic system as described above, but a conventional speaker has only a single function for generating sound, so it is desirable to make it multi-functional without increasing its size. That is.

In view of the above-mentioned problems of the conventional technology, the present invention is capable of receiving a communication light beam with a simple structure without greatly changing the structure from the conventional one, thereby providing a multifunctional function. it is possible to achieve reduction, ultimately, it is an object to provide an acoustic system comprising a speaker unit and it with suitable lamp as bathroom.

According to the present invention, the above problem is solved as follows.

Thus, the light receiver can be fixed and attached easily and reliably, and the added value can be increased without impeding the design.

(C) According to the invention described in claim 3 , since the communication light beam is infrared and the light receiver is an infrared light receiver, accurate communication by the light beam can be performed without being interrupted by light rays from the illumination device. It becomes possible.

(D) According to the invention described in claim 4 , since the protective cover of the light receiver and the speaker box can be used together, it is convenient and the acoustic performance of the speaker can be enhanced.
