Description

A portable wireless receiver having an in-ear jack and a wireless transceiver system having the same {Portable wireless receiver including audio output plug and jack and wireless transceiver system including the same}

The present invention relates to a portable wireless receiver and a wireless transmission/reception system having a jack for an in-ear earphone. More specifically, the present invention serves as a general wireless microphone transceiver and allows you to plug in an in-ear audio amplifier and an in-ear earphone so that you can directly monitor your own voice or performance in real time in the field so that there is no time delay by other methods of use. By adding a jack to the wireless microphone receiver circuit, you can use it the same as a conventional wireless microphone transceiver, and at the same time delay your own voice or performance sound in a large performance hall, outdoor stage, or indoor/outdoor busking place in a different way. It relates to a portable wireless microphone receiver capable of monitoring through an earphone jack without this, and a wireless transmission/reception system having the same.

In general, songs, performance sounds, or music on a large stage for performances and lectures or indoor and outdoor venues where broadcasting or music is performed are input to the mixer device through a wired or wireless microphone, and then transmitted to the public through an audio amplifier and speakers. In the sound emitted through a large hall or auditorium, or a wall or object in the room, there are delayed-timed sounds that are reflected back, such as echo, reverberation, and reflected sound. Because it provides an environment that is difficult to match, I use a monitoring speaker installed close to the stage to hear my song or voice or the accompaniment of instruments without time delay. There may be an unfavorable environment, and in this case, a wireless in-earphone dedicated system that can be plugged into each individual's ear is mainly used.

Most of the dedicated portable in-ear earphones are wireless rather than wired, which interfere with stage activities. And there is an inconvenience point that is not easy to handle. In particular, saxophonists and indie band musicians who attend many invited performances tend to not be able to use it easily because it is inconvenient to carry it with them every time. It is mainly used, but several wires are twisted together to provide an uncomfortable environment for performance activities.

Utility model registration No. 20-002500 is to mix and listen to the audio signal and video signal of an external device selected by the instructor, while listening to it, and output it to the TV monitor by wire, and at the same time, the voice signal of the external device and the user’s own voice signal It is configured to output to an external speaker by wire or to transmit it wirelessly to an external receiver. However, this design has a limitation that it cannot be used for a performance in which several users transmit music.

In addition, in the portable wireless transmission/reception system so far, the output of the wireless receiver is configured to be connected to the input terminal of an external audio amplifier. The speaker inside the in-ear earphone, which has a relatively low input impedance, that is, an impedance of 20 ohm to 50 ohm, cannot be played loudly, and only a very weak sound is played. In order to use in-ear headphones that sound loud, there is a problem in that an audio amplifier is added outside the wireless receiver and an in-ear earphone is inserted into the audio amplifier.

In order to improve this inconvenience, the present invention is a lightweight, small volume, simple installation, and easy to wear on the body without burden on the user. It is a technology that provides convenience for performing activities.

The present invention overcomes the disadvantages of the existing wireless transmission/reception system, such as the inconvenience of use and the inconvenient handling due to the large volume of the receiver. An object of the present invention is to provide a portable wireless receiver having an in-ear headphone jack that does not require an audio amplifier device.

In order to achieve the above object, the present invention provides an audio amplifier for earphones and a portable wireless receiver having an in-ear earphone jack to which an in-ear earphone can be connected.

The portable wireless receiver may further include a receiver plug for connection to an external amplifier speaker.

The portable wireless receiver may further include a receiver plug connected to a recording jack of an external smart phone to record sound.

In addition, the present invention is a system in which sound including instruments and voices played by a plurality of players is amplified in an audio amplifier through an audio mixer and then broadcast through a speaker, to be plugged into an input jack for sound input of the audio mixer device There is provided a wireless receiver for receiving sound from a portable wireless transmitter having a plug for audio input that can be connected, the wireless receiver having an in-ear headphone jack to which an in-ear earphone can be connected.

The portable wireless receiver may include an audio amplifier unit, and sound amplified through the audio amplifier unit may be transmitted through an in-ear headphone jack.

For one wireless transmitter, a plurality of wireless receivers may be connected.

In addition, the present invention includes a radio receiving antenna, a high frequency receiving unit, a radio frequency control unit for synchronizing a frequency matching the radio frequency of the other party, a sound demodulator, and a battery unit, and an audio amplifier for amplifying the sound transmitted from the radio transmitter Provided is a portable wireless receiver that further installs a unit and has an in-earphone jack for transmitting the amplified sound to the earphone through the audio amplifier unit.

The present invention is to provide a device for easy use by general players and instructors by providing a device that is smaller, lighter, easier to handle, and easier to carry than the bulky and inconvenient handling of the existing wireless transceiver monitoring device. .

Since the wireless receiver of the present invention has its own built-in amplifier, it is possible to record music on the smartphone through the receiver plug while listening to the amplified sound with the in-ear earphone, so it is equipped with multi-functions and has excellent marketability.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. And, in describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a view showing the overall configuration of a wireless transmission/reception system 1 of the present invention. The radio transmission/reception system 1 includes a radio transmitter 2 and a radio receiver 4 . The radio transmitter 2 includes a plug 2a for audio input connected to the PHONE jack of the sound mixer. The wireless receiver 4 includes a receiver plug 4a that connects to an external smart phone to output sound so that the smart phone can record, and an earphone jack 4b that delivers sound to the in-ear phone. “Sound” should be broadly interpreted to include not only human voice, but also all audible sounds such as musical instruments and ambient noise.

2 is a block diagram of the wireless transmitter 2 of the present invention.

The wireless transmitter 2 includes an audio input plug 2a to which audio sound is input from an external audio mixer, a sound modulator 103 that modulates the input sound, and a high-frequency mixing unit that changes the modulated sound to a high frequency. It includes a unit 104 , a frequency control unit 105 for controlling a high-frequency radio frequency for transmission, a radio transmitting antenna 106 and a battery unit 107 for supplying power.

One of the features of the present invention is that the condenser microphone unit 101 is replaced with an audio input plug 2a as shown in FIG. 2 .

3 shows the external appearance of a wireless transmitter 2' having a condenser microphone unit 101 in the prior art. When a song, lecture, or speech is mainly performed on the microphone 101', voice sound is input through the condenser microphone unit 101, is processed inside the wireless transmitter 2', and is transmitted to the wireless receiver.

However, if the audio input plug 2a is used instead of the condenser microphone 101 as in the present invention, the sound input to the wireless transmitter 2 is not only human voice but also various performance sounds and instrument sounds from the audio mixer. Therefore, the application area of the wireless transmitter 2 can be greatly expanded.

In particular, when the audio mixer includes all musical instrument sounds that are played simultaneously with one song, the sound transmitted through the audio input plug 2a is mixed in the wireless transmitter 2 and simultaneously transmitted to the wireless receiver 4 . Because it is transmitted, it is very convenient to transmit sound in the field such as a live performance.

That is, by inserting only the audio input plug (2a) of the wireless transmitter (2) of the present invention into an output terminal such as a phone of an audio mixer that is provided at most performance sites and controls the sound, if an appropriate receiver is provided, a plurality of players or The singer will be able to hear the same sound at the same time without time delay.

The structure of the wireless transmitter 2 of the present invention is not limited, and the manufacturing method is various, but when the condenser microphone and related members are removed from the wireless transmitter 2' of FIG. 3 and replaced with a plug 2a for audio input, It is sufficient, economical, and can reduce production costs. The plug 2a for audio input may use a 3.5mm plug.

FIG. 4 shows an actual photo of the wireless transmitter 2 of the present invention, which is an improvement of the conventional wireless transmitter 2' of FIG. 3 . Although the appearance and basic structure of the two devices are similar, it can be understood that there is a big difference in the scalability of uses and functions. The microphone 101' should be close to the person's mouth, and even if the body of the wireless transmitter 2' is mounted at the position closest to the human body, it should be invisible, especially if there are many viewers or spectators. Although it is common to wear it, the cable must be long, but in the present invention, only the audio input plug (2a) connected to the short-length cable needs to be installed, so the design and manufacture is very simple.

In addition, in the present invention, an extra wire is further provided in the audio cable 2b to which the audio input plug 2a of the wireless transmitter 2 is connected, and the extra wire is applied to the radio of the wireless transmitter 2 . It can be used by being connected to the circuit of the transmitting antenna 106 . This is because, if the length of the audio cable 2b is set to be 1/2 of the wavelength of the radio frequency, radio waves are best radiated. For example, if you want to transmit a signal of 1 GHz, since the wavelength in air of 1 GHz is 30 cm, if you make the length of the antenna wire inside the audio cable 2b connected to the wireless transmitting antenna 106 to 15 cm, an effective 1 GHz wireless antenna can be obtained. can be produced However, in the case of a monopole antenna, since the ground state has an image effect, it is manufactured with a length equal to a quarter of the frequency wavelength.

Next, the wireless receiver 4 of the present invention will be described.

The wireless receiver 4 of the present invention is most effective to provide a pair with the wireless transmitter 2 described above, but is not limited thereto.

As shown in FIG. 5, the wireless receiver 4 of the present invention includes a wireless receiving antenna 206 including a wire having a length corresponding to a quarter of a radio frequency wavelength, a high frequency receiving unit 204, and the other side of the radio It includes a radio frequency control unit 205 for synchronizing a frequency suitable for a frequency, a sound demodulation unit 203 , a battery unit 207 , and an audio amplifier unit 201 for connecting earphones or headphones.

The audio amplifier unit 201 is a configuration that does not exist in the existing wireless receiver, and the existing wireless receiver is used to make the amplifier and speaker loud by inserting a wirelessly received signal into an external audio amplifier or external microphone input of a speaker, Since the wireless receiver itself does not have a built-in audio amplifier, the sound output of the wireless receiver itself cannot supply satisfactory sound to the earphone. However, in the present invention, the audio amplifier unit 201 is installed, and the sound transmitted by the sound demodulator 203 can be used by directly plugging in the earphone through the audio amplifier unit 201 .

In addition, in the present invention, the signal transmitted from the sound demodulator 203 may be connected to the smartphone recording terminal through the receiver plug 4a to perform simultaneous recording in the smartphone. Accordingly, the user can listen to the sound amplified by the audio amplifier while wearing the in-ear earphone and simultaneously record the sound on the smartphone. This function is exhibited together with the wireless transmitter 2 of the present invention described above, and the instrument player transmits the sound from the audio mixer, including not only his own instrument, but also the sound of other players playing the instrument, to the radio transmitter 2 and the radio receiver. There is no time delay because you can listen to it in real time at the same time through (4), which is especially useful when playing multiple instruments. Since the wireless receiver 4 is made to be portable and easy to wear by attaching it to a user's pocket or belt rather than a conventional stand-fixed receiver, there is no concern about twisting the wired cable between several players.

Meanwhile, the receiver plug 4a is for receiving the sound transmitted from the sound demodulator 203 and transmitting it to an external smart phone to record music. The receiver plug 4a may transmit the sound to the amplifier to send the sound to the surroundings through the speaker.

According to the present invention, when multiple wireless receivers 4 are used simultaneously, one receiver can record the sound of the scene through the recording jack of the smartphone via the receiver plug 4a. The recorded music is very useful in that the music of the field transmitted from the wireless receiver 4 is recorded as it is, excluding the sound or noise of the audience.

Install two receiver plugs (4a) and put an add or switch button on the wireless transmitter (4) so that the output sound is recorded on the smartphone and delivered directly to the speaker of the amplifier without going through the audio amplifier unit 201 It is also possible to change

According to the present invention, one wireless transmitter 2 is installed, and the wireless receiver 4 is connected to a channel of the wireless transmitter 2 by pairing a plurality of pairs to connect a player of each musical instrument such as a guitar, saxophone, drum, etc. can play their own instruments while simultaneously listening to music with earphones through their respective wireless transmitters 4 , so it is convenient for performances and can provide harmonious music to the spectators.

6 is a diagram illustrating the external appearance of a wireless receiver 4' having a receiver plug 4a' in the prior art. A receiver plug 4a' is connected to the wireless receiver 4', but this is for insertion into an audio amplifier (not shown) and does not perform a recording function for a smartphone.

FIG. 7 shows an actual photo of the wireless receiver 4 of the present invention, which is an improvement of the conventional wireless receiver 4' of FIG. 6 . Although the appearance of the two devices is similar, it can be understood that there is a big difference in the internal configuration, use, and expandability of functions. The receiver plug (4a) and the earphone jack (4b) can use a 3.5mm plug and jack.

In the above, the present invention has been described with reference to the above embodiments, but it goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
