Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio receiving device that includes a part installed in a bathroom and a part installed outside the bathroom, and each part is equipped with a speaker.

[Prior Art] As a device for enjoying radio broadcasts, excursions, etc. in the bathroom, there is a device proposed in Japanese Utility Model Publication No. 63-29307.

This idea uses a remote control device for water heaters to enjoy radio broadcasts, etc., with speakers installed in the remote control device installed inside the bathroom (hereinafter referred to as "remote control") and the remote control installed outside the bathroom. By installing a tuner as a radio receiving section only on the remote control outside the bathroom, the output signal of the tuner is amplified and applied to the speakers of both remote controllers, so that it can be used in bathrooms where good reception of radio broadcasts is difficult. However, it is now possible to enjoy high-quality radio broadcasts.

[Problem to be Solved by the Invention 1] Thus, in the above invention, the amplified output signal is applied to the remote control inside the bathroom and the remote control outside the bathroom without selecting the speakers provided respectively. Since I am trying to enjoy radio broadcasts in the bathroom, when I enjoy radio broadcasts in the bathroom, the sound is reproduced even on the speakers outside the bathroom.

However, in reality, in many cases, it is rare to enjoy the same broadcast in the bathroom and outside the bathroom, such as in the kitchen, at the same time.
When enjoying a radio broadcast in the bathroom, it becomes harsh and distracting outside the bathroom.

Therefore, in order to prevent the sound from being reproduced on the speaker of the remote controller outside the bathroom, it is necessary to adjust the volume volume on the remote controller outside the bathroom to reduce the volume, which is troublesome.

The present invention provides a radio receiving device that is equipped with speakers inside and outside the bathroom, so that it is possible to easily enjoy radio broadcasts in the bathroom, and at this time, it does not get in the way outside the bathroom and does not require troublesome operations. To provide a radio receiving device; 6 which allows users to simultaneously enjoy radio broadcasting even outside the bathroom if necessary.

[Means for Solving the Problems] The present invention connects an in-bathroom unit installed in a bathroom of a building and an outside unit in the bathroom installed outside the bathroom in the building, and connects the outside unit to the bathroom unit. A radio receiving section for receiving radio broadcasting is provided, and the bathroom internal unit and the bathroom external unit are each provided with speakers, and an audio signal generated from the radio receiving section is amplified and selectively sent to each of the speakers. a radio receiving device for applying power, wherein the bathroom external unit is provided with a connection part for connecting to an external speaker;
When applying the amplified audio signal to the speaker of the bathroom unit, the technical means is to also amplify and apply the audio signal to the connection part.

In the present invention, when enjoying a radio broadcast in the bathroom, the audio signal is applied only to the speaker of the unit in the bathroom and not to the speaker provided in the unit outside the bathroom. The sound will not be reproduced.

Conversely, when you enjoy radio broadcasts using a unit outside the bathroom, the audio signal is applied only to the speakers of the unit outside the bathroom, so the sound is not reproduced from the speakers of the unit inside the bathroom. If you want to enjoy radio broadcasts on the bathroom outside unit at the same time, you can reproduce the sound by connecting external speakers, earphones, etc. to the connection part provided on the bathroom outside unit.

Therefore, you can enjoy radio broadcasts simultaneously inside and outside the bathroom.

[Effects of the Invention] According to the present invention, when enjoying a radio broadcast in the bathroom, the speaker installed outside the bathroom does not reproduce the sound, so it does not become a hindrance.

Furthermore, by connecting an external speaker or the like as necessary, it is possible to enjoy radio broadcasts simultaneously inside the bathroom and on the outside of the bathroom.
