First, the ultra-light wireless terminal 100 includes a wireless communication module 110 , a pairing module 120 , a control module 130 , and a power module 140 , and may further include a multi-party communication module 150 .

The wireless communication module 110 is compatible with the mobile communication terminal 200 equipped with wireless Wi-Fi, Bluetooth, Zigbee, etc. to transmit and receive voice.

The wireless communication module 110 uses a communication method for a personal wireless communication network (PAN) between terminals capable of short-range wireless communication, and can transmit and receive signals by forming a communication channel in the short-range.

For example, the Bluetooth communication method may perform communication using an Industrial Scientific Medical (ISM) band of a 2.4 GHz band. Here, the ISM band has a feature that can be used freely without a separate license. And, in the Bluetooth communication method, a guard band of 2 MHz band below the ISM band and a guard band of 3.5 MHz band above the ISM band are placed to prevent interference with other devices. The Bluetooth communication method basically uses a frequency hopping method, hopping 1600 times per second. Accordingly, the Bluetooth module may perform a series of operations for transmitting and receiving data through a wireless interface with the mobile communication terminal 200 capable of short-range wireless communication.

Here, the wireless communication module 110 receives a call connection from the mobile communication terminal 200 to provide a call mode or provides a sound source transmitter mode that receives and transmits a sound source from a plurality of sound source devices or mobile communication terminal 200. can

The pairing module 120 may perform pairing by exchanging data within a short distance within a predetermined distance. For example, the pairing module 120 may perform pairing using the NFC function, but is not limited thereto.

The pairing module 120 transmits a signal to the mobile communication terminal 200 located in a short distance, and when it is confirmed by the mobile communication terminal 200, pairing may be performed automatically.

In this case, it may be set to pair only with the mobile communication terminal 200 to which the security code is input using a separate security code.

It may be set to perform

When the control module 130 receives two or more signals from the wireless communication module, it generates a list of the received signals. In addition, the control module 130 may connect a signal selected from the generated list through a channel controller.

In this case, the connected signal may be limited to, for example, a sound source transmitter mode that outputs only a sound source through a speaker, rather than a call mode in which a sound source signal is transmitted and received to provide a call.

Here, the sound source includes all data that transmits a message through sound, such as voice and music.

The power module 140 provides power to the internal functions of the ultra-light wireless terminal 100 .

Finally, the multi-party communication module 150 can perform communication through Bluetooth, wireless Wi-Fi, Zigbee, etc., and implements a one-to-N call mode. However, the multi-party communication module is not limited to the above wireless communication methods.

The multi-party communication module 150 enables multi-party communication between the paired mobile communication terminal 200 and one or more different ultra-light wireless terminals 100 to be performed.

In this case, the ultra-light wireless terminal 100 provided with the multi-party communication module 150 may provide multi-party communication between the mobile communication terminal 200 paired as the master ultra-light wireless terminal and the plurality of ultra-light wireless terminals 100 .

Meanwhile, the multilateral communication module may be divided into a first channel unit and a second channel unit excluding the first channel unit. For example, it is possible to connect to a mobile communication terminal or a sound source device through a first channel unit to receive a signal, and to connect to one or more ultra-light wireless terminals through a second channel unit to perform multi-party communication.

Here, the number of channels allocated to the first channel unit and the second channel unit is not limited to a specific number, and can be easily changed and designed by a user later.

In addition, the multi-party communication module 300 is not built into the ultra-light wireless terminal 100 but is configured as an external module and is connected to the ultra-light wireless terminal 100 by wire or wirelessly to perform multi-party communication.

In addition, the mobile communication terminal 200 includes a pairing module 210 , a wireless communication module 220 , and an integrated circuit 230 , and may further include a multi-party communication module 240 .

Here, the mobile communication terminal 200 means a device equipped with arithmetic processing and mobile communication capabilities by having a processor, a memory, and a mobile communication module, respectively. For example, there is a personal computer, a handheld computer, a personal digital assistant (PDA), a mobile phone, a smart device, a tablet, and the like.

The pairing module 210 performs pairing with the ultra-light wireless terminal 100 using the received ID, number, and access numbering of the ultra-light wireless terminal 100 or through a function of automatically pairing through wireless communication.

The pairing module 210 may perform pairing with different mobile communication terminals 200 or a plurality of ultra-light wireless terminals 100 at the same time.

In other words, the pairing module 210 may perform one-to-one, one-to-many (one-to-N ) pairing with another mobile communication terminal or ultra-light wireless terminal 100 .

The wireless communication module 220 performs short-range or long-distance wireless communication, and exchanges data with other mobile communication terminals, servers, and the like.

In other words, it is paired with one or more ultra-light wireless terminals 100 during a call between different mobile communication terminals 200 so that multi-party communication is performed between different mobile communication terminals 200 and one or more ultra-light wireless terminals 100 .

For example, the ZigBee module set may be included as one of the chipsets in the main board of the mobile communication terminal 200 , and may be mounted on the SIM chip and included in the mobile communication terminal 200 , but is not limited thereto.

Also, the multi-party communication module 300 may be located outside the mobile communication terminal 200 . When the multi-party communication module 240 is not included in the mobile communication terminal 200 , it may connect with the mobile communication terminal 200 through the multi-party communication module 300 , which is a separate external module, to support multi-party communication.

Here, the multi-party communication module 240 and the multi-party communication module 300 perform the same function for supporting the multi-party communication of the mobile communication terminal 200, but do not necessarily have the same configuration.

For example, if multi-party communication is supported through Bluetooth, wireless Wi-Fi, and Zigbee supported by the multi-party communication modules 240 and 300, Bluetooth and wireless Wi-Fi are built-in as the multi-party communication module 240 inside the mobile communication terminal 200, However, multi-party communication can be performed by connecting the ZigBee set to the external multi-party communication module 300 .

Meanwhile, the multi-party communication modules 150 and 300 provided in the ultra-light wireless terminal 100 and the multi-party communication modules 240 and 300 provided in the mobile communication terminal 200 have the same configuration and repeated descriptions will be omitted.

For example, the size of the resistance may be adjusted according to the size of the resistance set corresponding to the angle at which the volume controller 12 rotates, and the intensity of the current may be adjusted accordingly to adjust the volume of the output sound.

According to this principle, when the volume control 12 rotates clockwise, the sound becomes louder, and when it rotates counterclockwise, the sound can become small.

The call on/off button 13 is a button formed in the inner region of the volume controller 12, and may connect a call with a terminal that transmits a signal by pressure applied from the outside, or end the connected call.

In addition, the LED 14 is a light indicator and is positioned between the volume control 12 and the call on/off button 13 in the shape of a wheel surrounding the call on/off button 13 . When the LED 14 receives a signal from the mobile communication terminal 200 or an external terminal (not shown), the LED 14 controls the color, illuminance level, lighting, etc. to display the signal reception status to the outside.

For example, when a signal is received from the mobile communication terminal 200 as shown in (b) and (c) of FIG. 3 , the ultra-light wireless terminal 100 outputs a certain sound to the speaker 10 or to the LED 14 . A user can recognize whether a signal is received through a preset color, an illuminance level, and whether or not it is lit.

In addition, it is possible to store the LED control table in which the illuminance of the LED, color, and whether to light the blinking signal in advance, and control the LED based on this.

As such, the volume control 12 , the call on/off button 13 , and the LED 14 are coupled to each other in a single circular shape and may be located on one side of the front of the ultra-light wireless terminal 100 .

And the earphone connect 15 is provided on the upper side of the ultra-light wireless terminal 100, when in contact with the terminal of the earphone, stops the sound output to the speaker, and outputs the sound to the earphone.

In addition, the display unit 19 displays one or more information among selected channel information, an identification number of a connected terminal, sound source information, and sound volume on the other surface of the housing.

For example, the level of the sound output at the current time may be displayed on the display unit 19 , and the change in the sound level adjusted through the volume controller 12 may be displayed on the display unit 19 . Accordingly, the user can more conveniently adjust the adjustment from the sound level at the current time to the desired sound level while checking the display unit 19 .

On the other hand, the display unit 19 is implemented as a touch screen, a liquid crystal display (LCD), and the like, but is not limited thereto. In addition, although it has been described that the display unit 19 is located on the other surface of the ultra-light wireless terminal 100, the location is not limited thereto, and it can be easily changed and changed by the shape of the housing of the ultra-light wireless terminal 100, arrangement with other components, etc. design is possible

2 (c) is a view showing the side of the ultra-light wireless terminal 100, including a power on/off button 16, a speaker operation button 17, and a channel adjuster 18.

The power on/off button 16 is a button for controlling the power supply in the ultra-light wireless terminal 100, and can stop the power supply or start the power supply by pressure applied from the outside.

The speaker operation button 17 controls the operation of the speaker mode in which the sound output from the speaker is emitted to the outside, and can control setting or release of the speaker mode.

Finally, the channel adjuster 18 is provided in the form of a scroll wheel for changing a channel in a received multi-channel signal.

The channel controller 18 may control to select and receive a channel in response to the movement of the scroll wheel by matching the angle of each scroll wheel corresponding to the frequency size in the channel or the assigned channel number.

The configuration disposed on the back, front, and side surfaces of the ultra-light wireless terminal 100 and the positions of the components are not limited thereto, and can be easily changed and designed later.

On the other hand, the mobile communication terminal 200 and the plurality of ultra-light wireless terminals 100 can perform pairing at the same time, and when security is required, a separate security code is set to confirm the set security code, and then pairing is performed. can

For example, by inputting a security code preset in the ultra-light wireless terminal 100 in the mobile communication terminal 200, pairing may be performed between permitted terminals.

In this case, the security code represents a one-time security code that can be changed in real time.

Next, the mobile communication terminal 200 checks whether two or more interlocked terminals exist (S420).

The mobile communication terminal 200 attempts a plurality of pairings at the current time point or checks whether there are paired terminals. The terminal identified here may include a plurality of ultra-light wireless terminals 100 as well as different mobile communication terminals.

For example, the mobile communication terminal 200 may perform pairing with one ultra-light wireless terminal 100 while performing a call with a different second mobile communication terminal.

At this time, the mobile communication terminal 200 may confirm that the two terminals are interlocked by checking one ultra-light wireless terminal 100 paired with the second connected mobile communication terminal.

And if there are not a plurality of terminals interlocked with the mobile communication terminal 200, a call is performed with the paired terminal (S430).

In this case, the call is provided in a one-to-one call mode.

On the other hand, if there are two or more terminals interlocked with the mobile communication terminal 200, the mobile communication terminal 200 converts to the multi-way communication mode (S440).

Here, the multi-party communication mode refers to a mode in which a call connection is performed between different second mobile communication terminals or ultra-light wireless terminals 100 in a call using the interlocked mobile communication terminal 200 as a repeater. Next, the mobile communication terminal 200 performs a multi-party call with two or more interlocked terminals (S450).

The mobile communication terminal 200 receives a sound source through a one-to-one wireless receiver to each interlocked terminal and transmits the sound source through a one-to-N wireless transmitter to perform a multi-party call.

As such, the mobile communication terminal 200 serves as a kind of repeater, and may transmit a sound source between the connected second different mobile communication terminal and the ultra-light wireless terminal 100 . In addition, the mobile communication terminal 200 may also collect the sound source as one call subject and transmit the sound source to the connected second mobile communication terminal and the ultra-light wireless terminal 100 .

In this case, even if the connection between the mobile communication terminal 200 and the second mobile communication terminal is terminated, multi-party communication can be performed with the ultralight wireless terminal 100 paired with the mobile communication terminal 200 . In addition, even if some of the plurality of ultra-light wireless terminals 100 paired with the mobile communication terminal 200 terminate the connection, the ultra-light wireless terminal 100 and the mobile communication terminal 200 that maintain the remaining pairing except for the terminated terminal. can perform multi-way communication.

In addition, the mobile communication terminal 200 may check a list of paired ultra-light wireless terminals 100 in addition to the mobile communication terminal in call, and may stop the connection with some specific ultra-light wireless terminals 100 selected by the user. there is.

Meanwhile, the mobile communication terminal 200 may further include a multi-party communication algorithm to efficiently handle situations occurring while performing a real-time multi-party call.

Then, a total of 15 ultra-light wireless terminals are connected through the mobile communication terminal 200-1 and the mobile communication terminal 200-2 to perform multi-party communication.

7 is an exemplary diagram for explaining multi-party communication between an ultra-light wireless terminal and a mobile communication terminal using a master ultra-light wireless terminal according to an embodiment of the present invention.

The master ultra-light wireless terminal 100-M means an ultra-light wireless terminal including a multi-party communication module, and although the multi-party communication module is shown in FIG. 7 as being provided therein, as shown in FIG. 1 described above, the multi-party communication module is an ultra-light wireless It is implemented as an external module located outside the terminal and can be connected to the ultra-light wireless terminal by wire or wirelessly.

The master ultra-light wireless terminal (100-M) is paired with the mobile communication terminal 200-2 and is connected to one or more ultra-light wireless terminals (100-1, ..., 100-n) located in a short distance while performing communication Multi-way communication can be performed.

The master ultra-light wireless terminal (100-M) displays a list of the ultra-light wireless terminals (100-1, ..., 100-n) in a short distance on the display unit, and the ultra-light wireless terminal 100 selected through a channel adjuster, etc. ) to transmit a connection signal to perform a connection.

Alternatively, when a request for connection with one or more ultra-light wireless terminals 100-1, ..., 100-n is received from the paired mobile communication terminal 200-2, the connection may be performed to provide multi-party communication.

The connection between the master ultra-light wireless terminal 100 -M and one or more ultra-light wireless terminals 100 is not limited thereto, and can be easily changed and designed by a user in the future.

At this time, the master ultra-light wireless terminal 100-M provides multi-party communication between the mobile communication terminal 200-2 and the ultra-light wireless terminal 100, and between the mobile communication terminal 200-2 and the ultra-light wireless terminal 100. In addition to multi-party communication, multi-party communication between the ultra-light wireless terminals 100-1, ..., 100-n may also be provided.

7, the master ultra-light wireless terminal (100-M) and a plurality of ultra-light wireless terminals (100-1, ..., 100-n) not provided with a multi-party communication module are illustrated, but depending on the situation, the master ultra-light wireless terminal A different master ultralight wireless terminal (not shown) may be connected to (100-M). For example, a plurality of ultra-light wireless terminals or a master ultra-light wireless terminal (not shown) may be connected to the master ultra-light wireless terminal 100 -M paired with the mobile communication terminal 200 - 2 . In addition, a plurality of ultra-light wireless terminals 100 or other master ultra-light wireless terminals are also connected to a plurality of master ultra-light wireless terminals (not shown), thereby extending the range of multi-party communication.

8 is an exemplary diagram for explaining an ultra-light wireless terminal that reproduces a sound source of a selected channel according to an embodiment of the present invention.

As shown in FIG. 8 , the ultra-light wireless terminal 100 - i is connected to the mobile communication terminal 200 , the sound source device 400 , and the sound source generator 500 through a network to transmit and receive data.

The ultra-light wireless terminal 100-i shows one terminal among a plurality of ultra-light wireless terminals 100-1, ..., 100-n, and in FIG. 8, the ultra-light wireless terminal 100-i is a sound source transmitter When a sound source is received in mode, a function of transmitting the received sound source as it is can be performed.

The ultra-light wireless terminal 100-i receives a plurality of signal channels (A.B.C, etc.) from each mobile communication terminal 200 , the sound source device 400 , and the sound source generator 500 . Here, a plurality of signal channels A.B.C can be expanded.

The ultra-light wireless terminal 100-i is a mobile communication terminal 200 corresponding to a plurality of signal channels (A, B, C), a sound source device 400, or a sound source generating device 500 through pairing for a specific channel. You can receive and output sound sources. At this time, when the ultra-light wireless terminal 100-i wants to change the channel, pairing can be performed with the mobile communication terminal 200, the sound source device 400 or the sound source generator 500 corresponding to the channel to be changed. there is.

In other words, when the ultra-light wireless terminal 100-i pairs and selects one channel from the receivable channel list (A, B, C) through the channel adjuster 18 provided on the side, various types of selected channels are selected. You can connect to one of the sound sources.

On the other hand, in the case of the ultra-light wireless terminal 100-M equipped with a multi-party communication module, the ultra-light wireless terminal 100-M is a sound source from the mobile communication terminal 200 through the multi-party communication module, the sound source device 400 or The sound source generating device 500 in real time with a plurality of ultra-light wireless terminals 100-i can connect

In this case, the ultra-light wireless terminal 100-M may list and store the signal channels received from the plurality of connected mobile communication terminals 200 , the sound source device 400 , or the sound generator 500 separately.

In addition, the ultra-light wireless terminal 100-M can connect to the selected channel by selecting one channel from the receivable channel list (A, B, C, etc.) through the channel adjuster 18 provided on the side. And the ultra-light wireless terminal (100-M) can reproduce the sound source received from the connected channel.

For example, if a guide broadcast is provided through the ultra-light wireless terminal in situations such as seminars, conferences, and assemblies, the ultra-light wireless terminal 100 -M may receive and transmit the guide broadcast.

And, in a meeting in which there are attendees who speak different languages, simultaneous interpreters interpret the contents of the speaker in various languages and transmit each language through each specific channel, and the attendees with the ultra-light wireless terminal 100-M You can listen to a specific language by selecting one of a plurality of interpretation channels. Of course, if you change the channel to another channel, it is possible to select a different language to listen to.

In addition, the ultra-light wireless terminal (100-M) uses the provided wireless communication module to connect the sound source device 400 or the sound generator 500 1:1 to receive the sound source signal while receiving the sound source signal 1:N through the multi-party communication module A plurality of ultra-light wireless terminals (100 - i ; i = 1, 2, ..., n) can be linked with

On the other hand, the ultra-light wireless terminal (100-M) uses a part of the multi-party communication module to receive various kinds of sound source signals in a plurality of multi-channels, and the ultra-light wireless terminal (100-M) using the remaining part of the multi-way communication module. By separating the function that connects to i), each function can be performed in real time.

For example, the ultra-light wireless terminal 100-M is connected to the mobile communication terminal 200, the sound source device 400, or the sound generator 500 transmitted in a multilingual conference to interpret in a specific language among N channels. A multi-way call can be performed by selecting and receiving a sound source and transmitting it while simultaneously connecting each sound source with a plurality of ultra-light wireless terminals 100-i.

In particular, in the case of simultaneous interpretation, the content presented in one language is interpreted by a simultaneous interpreter and then transmitted to a plurality of sound sources (using one of 200, 400, or 500 devices). For example, it is assumed that a plurality of sound sources 400-n simultaneously interpreted in multiple languages are transmitted to the sound source device 400-n (n=1,2,,,,N). Then, the sound source translated into each language is paired and received in the first channel unit of the multi-way communication module of the master ultra-light wireless terminal 100-M, and a plurality of ultra-light sources for each sound source in the second channel unit of the multi-way communication module The wireless terminal 100 - i may be connected. In this case, the plurality of ultra-light wireless terminals 100 - i may be referred to as slave ultra-light wireless terminals.

Hereinafter, a case of using a plurality of master ultra-light wireless terminals and a case of using one master ultra-light wireless terminal will be described in detail.

For example, in an international seminar, it is assumed that a presenter makes a presentation using English, and among 50 people who want to listen to the content, there are 30 people who want to hear it in Korean and 20 people who want to hear it in English.

In this case, the organizer of the international seminar can connect to a sound source device that provides a Korean sound source and an English sound source using two master ultra-light wireless terminals, respectively. In detail, the first master ultra-light wireless terminal is connected to a sound source device 400-1 that provides a sound source translated into Korean, and the second master ultra-light wireless terminal is connected to a sound source device 400-2 that provides a sound source in English. can connect

In this case, the first master ultra-light wireless terminal may perform one-to-one pairing with the sound source device 400-1 through the wireless communication module or may be connected to the sound source device 400-1 through the first channel unit of the multi-party communication module. The second master ultra-light wireless terminal is also applicable in the same way.

Accordingly, the slave ultra-light wireless terminal owned by 30 people who want to listen to the Korean sound source can be connected through the multi-party communication module of the first master ultra-light wireless terminal connected to the sound source device 400-1 that transmits the Korean sound source.

In other words, the first master ultra-light wireless terminal may receive the Korean sound source from the sound source device 400-1 through the multi-party communication module and transmit it to 30 connected slave ultra-light wireless terminals.

Similarly, the second master ultra-light wireless terminal connected to the sound source device 400 - 2 that transmits the English sound source may be connected to the slave ultra-light wireless terminal possessed by 20 people to transmit the English sound source.

Meanwhile, the organizer of the international seminar can connect to the slave ultra-light wireless terminal at the same time as the sound channel connection using one master ultra-light wireless terminal.

In detail, in the multi-party communication module of the master ultra-light wireless terminal, the first channel unit may be connected to the sound source device 400-1 and the sound source device 400-2, and the second channel unit may be connected to 50 slave ultra-light wireless terminals.

In this case, the 50 slave ultra-light wireless terminals may listen to the sound source by selecting the sound source device 400-1 or the sound source device 400-2 connected to the master ultra-light wireless terminal through the first channel unit. At this time, the first channel unit is composed of two channels, and it is possible to receive the sound source in Korean and English.

Therefore, the slave ultra-light wireless terminal owned by 30 people who want to listen to the Korean sound source can receive and listen to the Korean sound source from the sound source device 400-1 through the master ultra-light wireless terminal. Similarly, the slave ultra-light wireless terminal that wants to listen to the English sound source can receive the English sound source from the sound source device 400-2 through the master ultra-light wireless terminal and connect 20 ultra-light terminals to listen.

In this case, when the multi-party communication module configures the second channel part, the master ultralight wireless terminal may distribute and allocate the number of connectable slave ultralight wireless terminals corresponding to the first channel part. For example, if the multi-channel communication module of the master ultra-light wireless terminal can connect 100 channels, it can be connected to a sound source device that transmits 5 sound sources to the first channel unit. Then, the remaining 95 channels except for 5 channels among 100 channels may be allocated to the second channel unit.

Accordingly, if the five channels are evenly allocated to each sound source channel, the number of connectable slave ultra-light wireless terminals per each channel can be allocated to 19. As an example, the allocation of the number of connected terminals can be easily changed and designed by the user later in relation to the number of connections of the multi-party communication module, the number of sound source channels, the number of connected terminals corresponding to the preference of a desired channel, and the like.

In other words, the ultra-light wireless terminal 100 -M may transmit the sound source of the conference presenter through the multi-party communication module and simultaneously perform a multi-party call so that the conference presenter can make a query. At this time, in the case of a meeting presenter and a user who speaks a different language, interpreters who interpret different languages through the multi-way communication module of the ultra-light wireless terminal 100-M (for example, the interpreters use the sound source device 400-n, Through n = 1, 2, N) at the same time, multi-party communication is performed according to a preset order, so that the user can make inquiries smoothly.

Meanwhile, the sound source generator 500 may amplify the sound source signal through the connected amplifier 600 and then transmit it to the ultra-light wireless terminal 100 . In addition, the amplified sound source can be output (700) to a speaker installed in the field.

For example, the sound source generator 500 receives a sound source by input from the audio input unit (AI) or Aux (reserve terminal) in the spare of the amplifier, and the sound source through the wired (AO) or 1:1 wireless output of the amplifier. output and connect it to the multi-party communication module to perform multi-way communication mode.

In FIG. 8, only the sound generator 500 is connected to the amplifier 600 to transmit a sound source signal, but in addition to the sound generator 500, a sound source or a sound source device 400 from the mobile communication terminal 200 is included in the amplifier ( 600) to transmit a sound source, and this configuration can be easily changed and designed later. When a volume of sufficient power is required from the sound source, it is possible to amplify the sound source through the amplifier 600 and transmit it to the ultra-light terminals 100-i and the speaker 700 at the same time. When this is applied, it is exemplified that a large sound source can be simultaneously generated through the speaker 700 or the like in the field. In addition, while listening to (with one ear) the content of the seminar in one language (eg, Korean) being broadcast through the speaker 700 at the site, the content is simultaneously translated into another language (eg, English) It is possible to simultaneously listen to (using the other ear) with an earphone connected to the ultra-light terminal (100-i).
