BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless headphone of a type in which a sound signal from an audio device is wirelessly transmitted to the headphone using infrared rays.

[0002]

2. Description of the Related Art Music and the like are enjoyed in a sound reproducing device,
Alternatively, a speaker is generally used when listening to sound together with video with a television receiver, but headphones are used when the user is aware of the surroundings or enjoys himself alone at night or the like. Conventionally, headphones have been connected to audio equipment and the like with a cord and used within the length of this cord.However, if the length of the cord is short, the distance between the audio equipment and the listener is limited. The usability is poor. Therefore, if the cord is sufficiently long (for example, about 5 meters), the restriction on the seating position and the like is sufficiently relaxed, but there is a problem that the cord interferes when used nearby or when not used.

[0003] Therefore, this cord was abolished, and a sound reproducing device or the like was connected to headphones wirelessly.
Wireless headphones have been devised and put into practical use.
Many of these wireless headphones use infrared rays because they can transmit and receive stereo signals with good sound quality and efficiently.

The conventional wireless headphones used in this manner are generally of a head mounted type using a headband, and have a large housing. That is, because the housing has sufficient capacity,
In the housing, a receiving circuit, a power supply, and the like are housed in addition to the speaker unit. Because of the large size, the light receiving portion of the infrared signal was also large enough to select a place that would not interfere with the reception of the infrared signal, such as near the lower end of the headband.

[0005] However, wireless headphones are not limited to head-mounted types, and recently,
Even small inner ear type devices have emerged. In this case, since the capacity of the housing is limited, all of the light receiving unit and the receiving circuit are housed in a small case, and this case and the inner ear type headphones are connected. It was common to connect between with a cord.

[0006]

When the cord is connected between the case and the in-ear headphones as described above, an infrared signal from an infrared transmitter provided on the sound reproducing device side is received by the light receiving element in the case. Will receive it. By the way, we use in-ear headphones because we want to make them smaller so that they can move while listening to music, etc.From this perspective, even if we use in-ear headphones, The inability to store the case in a pocket or the like is extremely inconvenient in use. If the case is stored in a pocket, it will not be possible to receive infrared signals.

The present invention has been made in view of this point, and will provide a wireless headphone in which a case can be accommodated in a pocket or the like even in a wireless headphone using an in-ear type headphone. It is assumed that.

[0008]

According to the present invention, as a means for solving the above-mentioned problems, at least a rear portion of a housing of the in-ear type headphone is formed of a translucent material, and two insides of the housing are provided. Approximately 90 infrared receivers
The infrared light receiving element is connected to a receiving circuit by a cord while being stored in a different direction .

[0009]

With this configuration, infrared rays can be received by the in-ear headphones, so that the case housing the receiving circuit and the power supply can be housed in a pocket or the like. Thereby, usability is significantly improved. Also, two infrared light receiving elements are provided and
By changing the orientation by 90 degrees, it can respond to a wide range of infrared signals.
Will be able to respond.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a housing of an in-ear type headphone, in which a speaker unit 2 is provided.
And the substrate 3. 4 is a protector, 5 is a rubber ring, and 6 is a bushing. The tip of the cord 7 is connected to the speaker unit 2 and the board 3.

The rear part 8 of the housing 1 is formed of a translucent material, and an infrared light receiving element 9 is housed inside the rear part 8 of the housing 1. The infrared light receiving element 9 is connected to the receiving circuit 11 in the case 10 shown in FIG. Reference numeral 12 denotes a battery serving as a power supply.

As shown in FIG. 2, the infrared light receiving element 9
The two infrared light receiving elements 9 are substantially 90
It is arranged in different degrees. By arranging the infrared light receiving element 9 in such a manner that the direction is changed by approximately 90 degrees, it is possible to receive a wide range of infrared signals.

In this wireless headphone constructed as described above, the housing 1 is inserted into the ear canal with the protector 4 facing forward, as in the case of conventional ordinary in-ear headphones, but at least the rear part of the housing 1 is transparent. Since it is formed of a material having a characteristic, an infrared signal enters from this portion and the infrared light receiving element 9 receives the infrared signal. The received signal is sent by the code 7 to the receiving circuit 11 in the case 10, where it is processed into an audio signal, which is again sent to the housing 1 by the code 7 to operate the speaker unit 2.

In the embodiment described above, at least the rear portion of the housing 1 is formed of a light-transmitting material. However, the present invention is not limited to this. It goes without saying that the entire housing 1 may be formed of a translucent material.

[0015]

[Effects of the Invention] The present invention is a wireless headphone configured as described above, so that even in the case of an in-ear type, a case accommodating a receiving circuit and the like can be put in a pocket or the like. Usability will be significantly improved. And two infrared light receiving elements are provided.
Has been turned approximately 90 degrees, so there is no problem even if the user moves.
Will be usable.
