BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving device for receiving a radio wave.

[0002]

2. Description of the Related Art Conventionally, portable telephones and telephones called PHS (Personal Handy Phone) have been known as portable telephone devices capable of making telephone calls by radio waves. Thus, this type of telephone (hereinafter, referred to as a mobile phone in the sense of a portable phone, including all phones such as a mobile phone and a PHS phone) has a microphone when the speaker is put on the ear. It has a vertically long box shape that is arranged in the vicinity, and is formed to have a size that fits into a breast pocket or the like. In addition, mobile phones that transmit and receive image data as well as calls, for example, send and receive images via e-mail and the Internet, and image data as a videophone,
Portable videophones that transmit and receive moving image data are also being considered.

[0003]

SUMMARY OF THE INVENTION However, in the case of a mobile videophone, which needs to transmit and receive not only call voice but also image data, and to simultaneously hear and watch voice and image, If the mobile videophone is moved away from the face to view the displayed image data, it is difficult to transmit and receive audio because the microphone and speaker are too small. (Ear, mouth), there is a disadvantage that the displayed image becomes difficult to see this time. Also, when the mobile videophone is moved away from the face to view the displayed image data, the voice of the other party is difficult to reach the microphone of the mobile videophone, and there is a disadvantage that ambient noise enters. Was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and is a portable type capable of transmitting and receiving voices and images, but having a very good reception and reception of voices and images. It is intended to provide a device.

For example, music and other broadcasts can be received by a first wristwatch-type device, and the received content can be heard from a small ring-type reception device, and an image can be viewed by a second device. In addition, the present apparatus can also be used to listen to and view homepage information and various content information of the Internet and various networks including audio data and image data by using the telephone line. Although the audio signal is transmitted from the first device to the small ring-type receiving device by infrared rays, the transmission and reception may be performed after transmitting and receiving the signal in advance and establishing the link. The transmission format for transmission and reception may be any standard. Further, instead of using infrared radio, radio such as radio waves may be used. In addition, the design of both the first and second devices (including the finger-mounted small receiving device) is also optional, and it goes without saying that the specific detailed structure and the like can be appropriately changed.

According to the first aspect of the present invention, the first device attached to the arm can receive radio waves of voice and images, and the received sound can be heard by the sounding means.
You can listen in a style where your arm with the first device is close to your ear or pressed. And this style is like putting your palm on your cheek, thinking about something,
This style is common in daily life, such as sticking a cheek stick, and does not give unnaturalness to the surroundings. Then, the wireless image signal transmitted from the first device mounted on the arm can be received by the second device, and the received image can be viewed on the display means. Therefore, there is an effect that the reception of the sound and the visual recognition of the image can be performed extremely well, even though the portable type is used.

According to the second aspect of the present invention, since the first device mounted on the wrist can transmit not only the radio wave of sound and image but also the radio wave, it can be used particularly as a mobile phone. Then, the received sound can be heard by the small receiving device attached to the finger, so that the finger wearing the small receiving device can be heard close to or pressed against the ear. In the same manner as in the first aspect of the present invention, this style is a style often seen in daily life, such as thinking about something or putting a cheek on a cheek, such as putting a palm on a cheek. There is no unnatural surroundings. In addition, the small receiving device worn on the finger may emit a small volume because it is pressed against the ear, and an extremely small device can be used. Since there is no need to incorporate a sound generating means, the size and weight can be reduced. Then, the wireless image signal transmitted from the first device mounted on the arm can be received by the second device, and the received image can be viewed. Therefore, although it is a portable type, there is an effect that transmission and reception of sound and visual recognition of an image can be performed very well as in a videophone.

According to the eighth aspect of the present invention, since the first device mounted on the wrist can transmit as well as receive radio waves of sound and images, it can be used particularly as a portable telephone. The received sound is sent to the small receiving device mounted on the finger, and can be heard by the sound generating means of the finger-mounted small receiving device, so that the finger with the small receiving device is brought close to the ear or pressed. You can listen in the style you applied. However, similar to the above-described invention of claim 1, this style is a style often seen in everyday life such as putting a palm on a cheek, thinking about something, or sticking a cheek stick, Does not give unnaturalness to the surroundings. Further, the sound generating means provided on the small receiving device mounted on the finger may emit a small volume because it is pressed against the ear, and an extremely small device can be used. Since there is no need to incorporate a large volume sound generating means, the size and weight can be reduced.
Then, the wireless image signal transmitted from the first device mounted on the arm can be received by the second device, and the received image can be viewed on the display means. Therefore, although it is a portable type, there is an effect that transmission and reception of sound and visual recognition of an image can be performed very well as in a videophone.
