JP 2000-333268 A (FIG. 1)

  In the conventional bathroom acoustic device described above, there is only one type of acoustic device installed outside the bathroom. For example, when an MD player is connected, a CD player or other audio device cannot be connected, or an MD player is connected. There was a hassle of disconnecting and reconnecting other audio devices.

  In addition, since the control signal code differs depending on the type and manufacturer of the audio device, a remote control must be prepared for each audio device, but each remote control must be waterproof so that it can be used in the bathroom. In reality, it is impossible to prepare a remote control for each audio device.

  Then, an object of this invention is to provide the bathroom audio apparatus which does not produce the above-mentioned malfunction in view of said problem.

In order to solve the above problems, a bathroom acoustic apparatus according to the present invention includes a plurality of external input terminals, amplifies an audio signal input from one input terminal selected from these external input terminals, and enters the bathroom. In a bathroom acoustic device that sounds an arranged audio speaker, a remote control installed in the bathroom is provided with a plurality of selection switches corresponding to each input terminal, and the operated selection switch among the plurality of selection switches. When the corresponding external input terminal is selected and there is an external input terminal that is not connected to a device that transmits audio signals, the connection is possible even if the selection switch corresponding to the external input terminal that is not connected is operated. A selection prohibiting means for prohibiting selection to a terminal that is not yet provided, and further, a moving image signal input terminal that is paired with any of the plurality of input terminals is provided, Outputs a video signal inputted from the image signal input terminal to the installed bathroom TV in the bathroom, is switched from an input terminal which forms a video signal input terminal and the pair to the other input terminal does not make video signal input terminal and the pair And an image signal monitoring unit that outputs a still image signal to a bathroom television instead of a moving image signal.

  Provide multiple external input terminals, connect multiple audio devices etc. to each external input terminal, and select and play audio signals input from external input terminals with remote controller in bathroom, multiple audio devices The trouble of reconnecting to one external input terminal is eliminated. However, an audio device or the like is not necessarily connected to all external input terminals. For this reason, when operating the remote controller without selecting an external input terminal to which no audio device or the like is connected, music or the like is not reproduced from the audio speaker in the bathroom even when the remote controller is operated. And until you realize that you have selected an external input terminal that is not connected to an audio device etc., you do not know the reason why the music etc. is not pronounced, which may cause misunderstanding as if an abnormality such as a failure occurred in the bathroom acoustic device Become. Therefore, even if an external input terminal to which no audio device or the like is connected is selected by the selection prohibiting means, selection to that terminal is prohibited. Thereby, the external input terminal to which no audio device or the like is connected is not selected, and the usability of the remote controller is improved.

  At least one of the plurality of external input terminals is set as a dedicated external input terminal for inputting an audio signal from a bathroom television in which an image display unit and a television speaker are attached in the bathroom. An audio signal input from an external input terminal other than the external input terminal may be branched and output to a bathroom television so that it can be reproduced by a television speaker of the bathroom television. When the input TV sound is input to the bathroom TV, the TV sound is amplified infinitely, and a so-called howling phenomenon may occur. Therefore, the audio signal output to the bathroom television is limited to terminals other than the terminal to which the audio signal from the bathroom television is input. Thereby, sound can be output only from the bathroom and howling can be prevented.

  By the way, as an external audio device, there is a device that outputs an image signal in addition to an audio signal like a video device or a DVD device. On the other hand, a CD player or the like has only an audio signal and does not output an image signal. The image signal is displayed on the image display unit of the bathroom television. If the audio signal is switched to an audio device that does not output the image signal such as a CD player in that state, a sandstorm-like noise screen or blue screen is displayed on the bathroom television. . If the screen is inconvenient, the following configuration may be used.

  That is, in addition to the plurality of external input terminals, an image signal input terminal for inputting an image signal is provided, and the input image signal is output to the bathroom television. Image data storage means for storing image data to be output is provided. Thereby, when an image signal is not input, the image data memorize | stored in the image data memory | storage means are displayed, and the usability of a bathroom sound apparatus is improved.

  If an infrared signal emitting means for receiving a signal transmitted from a remote controller in the bathroom and emitting the signal as an infrared ray to a device connected to the external input terminal is provided with one remote controller in the bathroom. A plurality of devices such as audio devices can be controlled.

  As is apparent from the above description, the present invention can connect a plurality of external devices, and can play music from these external devices and operate external devices with a remote controller in the bathroom. .

  Referring to FIG. 1, reference numeral 1 denotes a multi-amplifier that is a bathroom acoustic apparatus according to the present invention. This multi-amplifier has an amplifier function that amplifies the input audio signal and a selection function that selects one external input terminal from a plurality of external input terminals and inputs the audio signal from the external input terminal to the amplifier function And. The amplified audio signal is output to the audio speaker 11 installed in the bathroom BR, and the pair of audio speakers 11 are sounded. The external input terminal is a terminal to which an audio signal is input. In the present embodiment, four external input terminals 2 are provided. In addition to these external input terminals 2, an image signal input terminal 12 for inputting an image signal from the outside is provided.

  The image signal input from the image signal input terminal 12 is output from the image signal output terminal 13. A monitor unit 31 of a bathroom television is attached to the bathroom BR. The monitor unit 31 is provided with a liquid crystal display unit and a television speaker. The monitor unit 31 receives an image signal sent from the tuner unit 3 installed behind the ceiling of the bathroom BR and displays a television image. In response to the audio signal sent from the unit 3, the TV speaker is configured to ring.

  The image signal output from the multi-amplifier 1 is input to the tuner unit 3 and connected to display the video signal on the monitor unit 31 of the bathroom television. The selected audio signal input to the multi-amplifier 1 is branched in the multi-amplifier 1 and output from the external output terminal 14 to the tuner unit 3. The audio signal input to the tuner unit 3 is reproduced from the television speaker of the monitor unit 31.

  The multi-amplifier 1 is connected to a light receiving unit 15 attached so that the light receiving portion faces the bathroom BR. An infrared remote controller 4 is placed in the bathroom BR, and the infrared light emitted from the remote controller 4 can be received by the light receiving unit 15. Since the remote controller 4 has a function of operating the bathroom TV, the infrared light emitted from the remote controller 4 is transmitted to a light receiving unit (not shown) attached to the monitor unit 31 in addition to the light receiving unit 15. Is also received.

  Infrared light received by the light receiving unit 15 is converted into an electrical signal and output as it is to the input / output terminal units 51, 52, 53 installed in a room other than the bathroom BL such as the living room LR. When a communication line is connected to these input / output terminal units 51, 52, and 53, and a light emitting unit 54a is connected to the tip of the communication line, the light emitting unit 54a emits infrared rays on which signals are superimposed.

  Each input / output terminal unit 51, 52, 53 is provided with a terminal for inputting an audio signal, and each terminal is connected to the external input terminal 2. Accordingly, an audio signal output from the DVD player 61 or the MD player 62 is input to the external input terminal 2. In particular, the input / output terminal unit 51 is provided with a terminal for inputting an image signal, and the terminal is connected to the image signal input terminal 12. Therefore, the image signal output from the DVD player 61 is input to the image signal input terminal 12. In the present embodiment, no external device is connected to the input / output terminal unit 53.

  2 and 3, the remote control 4 is provided with a selection switch 41. The remote controller 4 is a so-called learning remote controller, which stores a control code adopted by each manufacturer, and can make a desired control code correspond to each selection switch 41. When one of the four selection switches 41 is pressed, the remote controller 4 emits an infrared signal of a control code corresponding to the pressed selection switch. Accordingly, when another selection switch is pressed after that, infrared rays of a control code corresponding to the selection switch pressed later are emitted. Since the remote controller 4 is also used for controlling a bathroom television, the infrared light of the bathroom television control code can be emitted at any time by pressing a dedicated switch on the remote controller 4.

  On the other hand, the multi-amplifier 1 is provided with means for setting to which terminal of the external terminals 2 an external device is connected. The means is, for example, a dip switch, and a dip switch having four dip corresponding to each of the external input terminals 21, 22, 23, and 24 which are the four external input terminals 2 is built in the multi-amplifier 1. By turning on the dip corresponding to the external input terminal to which the external device is connected, it is possible to recognize to which external input terminal the external device is connected.

  Of the selection switches 41 of the remote controller 4, “TV” corresponds to the external input terminal 20, “1” corresponds to the external input terminal 21, “2” corresponds to the external input terminal 22, and “3” is external. This corresponds to the input terminal 23. A TV audio signal from the tuner unit 3 is input to the external input terminal 20, and an audio signal from the DVD player 61 is input to the external input terminal 21 via the input / output terminal unit 51. An audio signal from the MD player 62 is input via the input / output terminal unit 52. Since no audio signal is input to the external input terminal 23, only the dip corresponding to the external input terminal 23 is in the off state.

  An amplifier unit 16 is built in the multi-amplifier 1, and an audio signal input to the amplifier unit 16 is amplified and output to the audio speaker 11. In the multi-amplifier 1, a first changeover switch 71 and a second changeover switch 72 are connected in series. The first changeover switch 71 selects one of the three external input terminals 21, 22, and 23 and outputs a sound signal from the selected one external input terminal. The output audio signal is branched and output from the external output terminal 14 to the tuner unit 3. The second changeover switch 72 allows the amplifier unit 16 to input either the audio signal output from the first changeover switch 71 or the audio signal of the bathroom television input from the external input terminal 20. These two changeover switches 71 and 72 are changed over by a selection switch 41 of the remote controller 4.

  That is, when the “TV” switch of the selection switch 41 is pressed, the second changeover switch 72 is activated and the audio signal from the tuner unit 3 is input to the amplifier unit 16. Therefore, the audio from the television 11 is generated from the audio speaker 11.

  Next, when the “1” switch of the selection switch 41 is pressed, the second changeover switch 72 is switched and the first changeover switch 71 is switched to the external input terminal 21. Therefore, the audio signal from the DVD player 61 is input to the amplifier unit 16, and the audio signal from the DVD player 61 is generated from the audio speaker 11. The audio signal from the DVD player 61 is branched to the tuner unit 3, and the image signal from the DVD player 61 is also output to the tuner unit 3.

  In this state, the moving image from the DVD player 61 is displayed on the monitor unit 31, but the sound is also reproduced from the television speaker. In contrast to the high-quality sound from the audio speaker 11, the sound reproduced from the television speaker has a lower sound quality. Therefore, there is a case where it is desired to stop the sound generation from the television speaker. At this time, when the TV mute switch 42 is pressed, the mute process is performed in the bathroom television, and the volume becomes zero. However, when the volume is reduced to zero by the mute processing as described above, a display indicating that the volume is always zero is continuously displayed on the screen. For this reason, it may be an obstacle to watching moving images. In this case, the volume may be lowered by the “TV volume” switch, but the switch must be kept pressed until the volume is lowered.

  Therefore, an “AV mute” switch 43 is provided on the remote controller 4. When the switch 43 is pressed once, a signal for decreasing the volume continues to be transmitted to the bathroom television while the volume is sufficiently zero. Finally, a signal for raising the volume by one level is output. Then, the volume of the television becomes 1 instead of zero. In this case, even if a display with a volume of 1 is displayed on the monitor unit 31, the display disappears after a few seconds. Therefore, it does not get in the way of watching videos.

  Next, when “2” of the selection switch 41 is pressed, the first changeover switch 71 is switched, and the audio signal from the external input terminal 22 is input to the amplifier unit 16. Further, the image signal monitoring unit 8 operates to block the image signal from the DVD player 61 from being output from the image signal output terminal 13. Note that still image data is stored in the image signal monitoring unit 8 in advance. Instead of the image signal from the DVD player 61, the stored image signal is transferred from the image signal output terminal 13 to the tuner unit 3. Output. Then, as soon as the DVD player 61 is switched to the MD player 62, a noise screen or a blue screen is prevented from being displayed on the monitor unit 31, and the stored still image is displayed, causing discomfort. I tried not to. If the “AV volume” switch 44 is operated in this state, infrared light is emitted from the light emitting portion 54a, and the volume of the MD player 62 is increased or decreased.

  Next, when “3” of the selection switch 41 is pressed, in this embodiment, since the external device is not connected and the dip is turned off, the changeover state of both the changeover switches 71 and 72 changes. I tried not to.

  In the configuration shown in FIG. 2, two changeover switches 71 and 72 are connected in series. The reason for this configuration is to prevent the so-called howling phenomenon from occurring when the audio signal input from the tuner unit 3 is input to the tuner unit 3 again. In order to prevent the occurrence of the howling phenomenon, another configuration may be employed. For example, as shown in FIG. 4, a four-circuit selector switch 73 is used and the output side of the selector switch 73 is connected to the external output terminal 14. An opening / closing switch 74 may be interposed between the two, and the opening / closing switch 74 may be turned off only when the external input terminal 20 is selected.

  By the way, although the presence or absence of the input of the audio | voice signal to the external input terminal 2 was installed with the dip switch in the said embodiment, the short circuit resistance was built in the connector connected to an external input terminal, and the connector was connected. May be automatically detected on the multi-amplifier 1 side so that the selector switch is not switched to the external input terminal to which the connector is not connected.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
