Description

In-ear wireless earphones {RADIO EAR-PHONE FOR USE IN EAR}

The present invention relates to an ear-type wireless earphone, and more particularly, to an ear-type wireless earphone which induces a voice or sound transmitted through an earphone jack from an electronic device to a wireless earphone body by using a transmission loop and transmits the same to a user. will be.

In general, earphone is an abbreviation of earphone receiver, among which crystal receiver is a structure that operates the diaphragm using piezoelectric effect of crystal element, and magnetic receiver is a diaphragm by flowing voice current through coil. It is structure to operate. In addition to the type that directly plugs into the ear hole, there is a thing that is worn on the head, and this is called a headphone (headphone), and according to its characteristics, there is a trend toward high quality or miniaturization, and many companies produce high quality wired earphones.

In addition, even in a special situation or a person working in a special job is using wired earphones or wireless earphones to receive other situations, the use of wireless earphones are increasing rapidly due to the development of automobiles and mobile phones.

As described above, the conventional wired earphone is a line for connecting the jack and the earphone body to the jack for connecting to the electronic device, and converts the electrical voice signal input through the line into vibration to generate a small wave (疏密 波) It is composed of a speaker that delivers, the function of delivering the voice (sound) output from the electronic device to the user is maintained, but the activity radius is limited only by the line connecting the mobile phone and the earphone body to a lot of users In addition, since the earphone or the transceiver is exposed to the outside, there is a problem that cannot be used in a specific situation or a specific place.

In addition, the conventional wireless earphone has to be separately implemented a device for receiving voice (sound) from the electronic device wirelessly, and in the case of an electronic device corresponding to the wireless earphone had to be implemented separately. In addition, in the transmission / reception method between the wireless earphone and the mobile phone, an infrared communication or RF signal is used, and thus, a complicated receiver is required. Therefore, the size of the transmission and reception device and the wireless earphone are not only large, but also the production cost. In addition, there is a problem that the additional measures to adjust the channel when using the communication method as described above.

In addition, even in the case of the conventional wireless earphone, the device itself is large, and thus, the problem that the wired earphone cannot be used in a special situation or a special place cannot be solved.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object of the present invention has been implemented in the ear type to eliminate the problem that the device is exposed to the outside when worn, such as the conventional wired earphones and wireless earphones. In addition, the use of inductive electromotive force eliminates the need for a circuit for processing high frequency signals, and thus provides an inductive wireless earphone capable of reducing the size and production cost of the device by reducing components necessary for implementing the device.

Another purpose is to transmit and receive wirelessly through induction electromotive force without using RF signal or infrared ray that need to match channel selection between transmitting device and receiving device, so that it can be conveniently used without the hassle of conventional channel matching. It is to provide an ear type wireless earphone.

In order to achieve the above object, the earphone-type wireless earphone according to the present invention includes an earphone for transmitting a voice output from an electronic device having an earphone jack to a user.

A transmission loop having an earphone jack insertable into the earphone jack of the electronic device, for wirelessly inducing the induction electromotive force generated through an electrical voice signal output through the earphone jack from the electronic device; And

Implemented so as not to be exposed to the outside when worn in the ear, and amplifies the electric voice signal derived from the transmission loop and converts into a small wave (sound wave) through a diaphragm, characterized in that consisting of a wireless earphone body for transmitting to the user.

As a guide to the wireless earphone body 200. At this time, the transmission loop 100 is not operated by any driving means, but is connected (connected) to the earphone jack implemented in the electronic device, and guides the voice to the wireless earphone main body 200.

In addition, the wireless earphone main body 200 is implemented so as not to be exposed to the outside when worn in the ear, the amplified wave generated through the vibration plate after amplifying the electric voice signal wirelessly induced through the induced electromotive force from the transmission loop 100 ( It plays a role of delivering a ripple to a user, and is composed of a coil 210, a voice amplifier 220, a speaker 230, a volume controller 240, a battery 250 and a housing 260.

First, the coil 210 in the wireless earphone main body 200 serves to convert the voice wirelessly induced through the induced electromotive force from the transmission loop 100 into an electrical signal and output the electrical signal to the voice amplifier 220.

In addition, the voice amplifier 220 in the wireless earphone main body 200 serves to amplify and output the electric voice signal wirelessly input from the coil 210 to the speaker 230. In this case, the voice amplifier 220 is implemented in the form of a chip, and connects the coil 210, the speaker 230, the volume controller 240, the battery 250, and the like as shown in FIG. 2.

In addition, the speaker 230 in the wireless earphone main body 200 converts the electric voice signal amplified from the voice amplifier 220 into vibration using a diaphragm to generate a small wave and transmit it to the user. do.

In addition, the volume controller 240 in the wireless earphone main body 200 is connected to the voice amplifier 220 serves to adjust the basic volume through the adjustment of the resistance. At this time, the volume controller 240 is a volume control bar 241 of the "-" shape is exposed on one side of the housing 260, the internal resistance changes when the volume control bar 241 is rotated by a user The default volume is adjusted.

The battery 250 in the wireless earphone main body 200 serves to supply power to each component.

In addition, the housing 260 in the wireless earphone body 200 is implemented so as not to be exposed to the outside when worn in the ear, the coil 210, the voice amplifier 220, the speaker 230, the volume control 240, etc. While fixing to the inside, the battery case 251 is provided to detach the battery 250 on the rear side, and serves to implement the shape of the device. In this case, the housing 260 may be made of plastic and silicon, and the battery case 251 may be detachably used.

In addition, as shown in Figure 2, the wireless earphone main body is provided with a plurality of capacitors for preventing the backflow or noise in each configuration, as shown in Figure 5, to configure the main body to the output enhancement type In order to amplify the electrical voice signal before the amplification in the voice amplifier 220, it may further include an amplifier 300 for removing the noise and at the same time stable.

Next, an operation process of the earphone-type wireless earphone according to an embodiment of the present invention having the above configuration will be described with reference to FIGS. 1 to 6.
