Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved technology of a conventionally used earphone, and an antenna, a receiver and a speaker are provided in the earphone so that many audio signals transmitted from the outside can be captured and reproduced. Regarding the built-in earphone receiver set.

[0002]

[Prior art]

 Conventionally, earphones with a built-in speaker have been widely available as earphones that are worn on the ears. By connecting the connection terminals of the earphones to a separately provided audio output device or audio reproduction device, the audio output from these devices can be heard directly by the ear. 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 to select a channel or reproduce a sound, but a speaker that simply outputs the input sound. It is configured to have the function as.

[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 is very limited. The present invention has been made to solve the above problems, and its purpose is to catch various audio signals sent by radio with the earphone itself and to separate output and volume control of desired audio signals. The purpose of this is to provide an earphone receiver with a built-in antenna that expands the application of the earphone and makes it easier to use by making it possible to freely use the adjustment and selection means provided on the body.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the invention described in (Claim 1), a receiving antenna, a receiver for reproducing the radio wave received by the antenna, and a voice signal reproduced by the receiver are connected to the receiver. The earphone part, which has a speaker for outputting in the earphone, is provided separately from the earphone part, has a control circuit for selecting the volume and channel of the earphone part, and It is characterized in that it comprises an adjusting / selecting means also provided with a transmitting section for transmitting to an antenna.

[0005]

[Action]

 According to the invention having the above-mentioned configuration (claim 1), the receiving antenna and the receiver for reproducing the electric wave received by the antenna and the receiver connected to the receiver are output, and the audio signal reproduced by the receiver is output. It has an earphone part with a speaker for operating the earphone and has a control circuit for selecting a channel received from the antenna of the earphone part, scanning, and adjusting the volume. In addition, since the adjustment / selection means, which also includes a transmission section for transmitting to the antenna of the earphone section, is provided separately, it is possible to adjust each type of audio signal transmitted wirelessly from a distance. By operating the selection means, it is possible to freely output the desired audio signal and adjust the volume from another location as well. It is possible to improve on the jar surface.

【Example】

 An embodiment of an earphone receiver set 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 set incorporating the 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 the earphone receiver set incorporating the antenna of the present invention. As shown in FIGS. 1 and 2, an earphone receiver set 1 with a built-in antenna according to the present invention is roughly composed of an earphone unit 2 and an adjuster 3 connected via a cable 30. The earphone unit 2 includes a flat-shaped speaker 5 and a bar antenna 4 which are arranged so as to face the radio reception bar antenna 4 toward the inner ear side in an ear mounting portion 2a formed to fit the ear. And a receiver circuit 6 which reproduces the audio signal received by the bar antenna 4 by radio. On the regulator 3 side, a 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 (pre-selector) circuit 10, and a scanning unit 11 are provided. , Volume 12, etc. In the drawing, 13, ... Are preset buttons. FIG. 3 is a circuit block diagram showing the basic circuit configuration of the earphone receiver 1 that constitutes the earphone unit. The external reception antenna 4 includes a high frequency amplifier circuit 14, a frequency conversion circuit 15, and a frequency conversion circuit 15, which constitute a voice reproduction circuit system. It is connected to the speaker 5 via the intermediate frequency amplifier circuit 16, the detection circuit 17, and the low frequency amplifier circuit 18. Further, the frequency conversion circuit 15 is connected via an oscillation circuit 19 to a control command input section 20 having a receiving antenna 20a built therein. The control command input unit 20 is composed of a generally used reception signal reproducing circuit similar to the above audio reproducing circuit system, and is provided with a fine adjustment circuit for preventing interference. On the other hand, it is provided separately from the earphone section, has a control circuit 8 for selecting the volume and channel of the earphone section, and also has a transmitting section 21 for transmitting to the antenna of the earphone section. In the adjuster 3 as the adjusting / selecting means, a command signal for controlling the desired volume and channel is transmitted to the control command input section 20 via the transmitting antenna 21a of the transmitting section 21. The transmission unit 21 is connected to the control circuit 8, and the control circuit 8 is connected to the scanning 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 set 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 connecting to the receiver circuit 6 and outputting the reproduced audio signal in the receiver circuit 6 are provided. Preset buttons 13 provided in the earphone section 2 and for the receiver circuit 6 for selecting a channel received from the antenna 4, scanning, and adjusting the volume, ..., Scan section 11 and the volume 12 can be adjusted by the adjuster 3 located at a distance, so that the user can freely operate the desired volume by simply operating the volume 12 or the preset button 13 of the adjuster 3 at hand. It enables signal output and allows you to listen at your own desired volume, improving usability. It becomes Rukoto. As described above, according to the earphone transceiver set A, the application of the earphone can be remarkably expanded as compared with the conventional earphone, and the usability can be improved.
