Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved technique of an earphone that has been conventionally used, and by providing an antenna, a receiver and a speaker in the earphone, it is possible to catch and reproduce many audio signals transmitted from the outside. Regarding the earphone receiver with built-in antenna.

[0002]

[Prior Art]

 Conventionally, earphones that have a built-in speaker have been commonly used as earphones that are worn on the ear. This earphone is designed so that the sound output from these devices can be heard directly by connecting the connection terminal of the earphone to a separately provided audio output device or audio reproduction device. In this way, the earphone is used to listen to the sound from some kind of audio output device, and the earphone itself does not have a function of selecting a channel or reproducing the sound, but simply outputs the input sound. It has a function as a speaker.

[0003]

[Problems to be solved by the device]

 However, the conventional earphone has only a function of wearing it in the ear and listening to the sound from the sound output device or the sound reproduction device, and its use has been limited. The present invention has been made to solve the above problems, and the purpose thereof is to catch various audio signals sent by radio with the earphone itself and freely adjust the output and volume of desired audio signals. By making it possible, we are expanding the use of earphones and providing earphone receivers with built-in antennas that are easy to use.

[0004]

[Means for Solving the Problems]

 To achieve the above purpose,

According to the invention as set forth in claim 1, a receiver for reproducing an electric wave received by an antenna for reception and an antenna for receiving the antenna, and a speaker connected to the receiver for outputting an audio signal reproduced by the receiver. In the earphone, and to the receiver is connected a controller that has a control circuit for selecting the channel received from the antenna, scanning, and adjusting the volume. It is a feature.

[0005]

[Action]

 Consists of the above configuration

1. An earphone comprising a receiving antenna, a receiver for reproducing a radio wave received by the antenna, and a speaker connected to the receiver for outputting an audio signal reproduced by the receiver. In addition, the receiver has a built-in control circuit for selecting the channel received from the antenna, scanning, and adjusting the volume. Since the earphone itself catches various audio signals that are sent, and the output and volume of the desired audio signal can be adjusted freely, the earphone can be used for a wider range of applications and can be used more easily.

【Example】

 An embodiment of an earphone receiver with a built-in antenna according to the present invention will be described below with reference to the drawings. 1 is a front view of an earphone receiver with a built-in antenna of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a circuit block diagram showing a basic circuit configuration of an earphone receiver with a built-in antenna of the present invention. As shown in FIGS. 1 and 2, an earphone receiver 1 with a built-in antenna according to the present invention is roughly composed of an earphone unit 2 and a controller 3 connected via a cable 30. The earphone 2 is connected to the wireless reception bar antenna 4 and the flat panel speaker 5 and the bar antenna 4 which are arranged so as to face toward the inner ear side in the ear mounting portion 2a formed to fit the ear. The receiver circuit 6 reproduces the voice signal received by the bar antenna 4 and received by radio. On the regulator 3 side, the power switch 9 for applying the voltage supplied from the battery 7 to the receiver circuit 6 and all circuits such as a control circuit 8 described later, a preset (preselector) circuit 10, and a scan unit. 11, the volume 12, and so on. In the figure, 13, ... Are preset buttons. FIG. 3 is a circuit block showing the basic circuit configuration of the earphone receiver 1. The antenna 4 includes a high frequency amplification circuit 14, a frequency conversion circuit 15, an intermediate frequency amplification circuit 16, a detection circuit 17, and a low frequency amplification circuit 18. It is connected to the speaker 5 via the. Further, the frequency conversion circuit 15 is connected to the control circuit 8 via the oscillation circuit 19, and the control circuit 8 is connected to the scan unit 11. A volume 12 is connected between the detection circuit 17 and the low frequency amplification circuit 18, and the volume 12 is connected to a control circuit 8 via a preset circuit 10. The operation of the earphone transceiver 1 of this embodiment configured as described above will be described. First, the receiving antenna 4 and the receiver circuit 6 for reproducing the radio wave received by the antenna 4 and the speaker 5 for being connected to the receiver circuit 6 and outputting the audio signal reproduced by the receiver circuit 6. The earphone section 2 is equipped with the preset buttons 13, ..., The scanning section for selecting the channel received from the antenna 4 in the receiver circuit 6, or for scanning or adjusting the volume. 11 and the volume 12 are connected through the control circuit 8 to configure the adjuster 3, so that various earphones 2 themselves can catch various audio signals transmitted by radio. Moreover, the user wearing the earphone unit 2 operates the adjuster 3 connected to the earphone unit 2 with the cable 30 to enable the user to freely output a desired audio signal. You can listen to your favorite volume. As described above, according to the earphone transceiver 1, the application of the Bayer horn can be remarkably expanded as compared with the conventional earphone, and the usability can be improved.
