Description

Voice transceiver

The technology described below relates to a voice transceiving device having a voice activated transmission (VOX) function.

Radios generally use half-duplex communication. Half-duplex communication means that signals can be transmitted in both directions, but not simultaneously. That is, after transmitting a signal from one radio, it is possible to transmit a signal from another radio.

As the radio uses half duplex, the radio must switch between receive and transmit modes. That is, in a reception mode, a voice signal of the other party wirelessly received from another radio is received and output to a user, and in a transmission mode, the user's voice is transmitted and wirelessly transmitted to another radio.

Transmit / receive switch is provided for switching between transmit mode and receive mode. The transmit / receive switch may be implemented by a push to talk (PTT) button. The PTT button literally means pressing the button and talking. If the user does not press the PTT button, the radio operates in the reception mode to process the voice of the other party wirelessly received from the other radio and output it to the user. When the user presses the PTT button, the radio operates in the transmission mode and transmits the user's voice to other radios.

In order to solve the problem of the user pressing the button directly, a technology for switching between the transmission mode and the reception mode has been developed.

The prior art has a problem that a malfunction occurs when the surrounding noise occurs in addition to the user's voice. Bone conduction microphones, which are often used in industrial or military radios, are also exposed to external noise and cause malfunctions.

The technology described below is intended to provide a radio using a device that is integrated into the ear of the user by implementing the microphone and the speaker integrally.

Problems of the technology described below are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

The transmitter includes a voice detector for detecting a user voice input from a microphone, a voice modulator for modulating the voice signal detected by the voice detector into a transmission frequency signal, and a wireless transmitter for transmitting the modulated signal to a duplexer.

The receiver includes a wireless receiver for demodulating a voice signal by receiving a signal transmitted from the duplexer, and a voice amplifier for amplifying the voice signal demodulated by the wireless receiver.

The voice input / output unit includes a microphone for converting a voice signal transmitted from the user's ear canal into an electrical signal, a speaker for transmitting the other party's voice received from the receiver to the ear canal, and a housing part in the form of an earphone housing the microphone and the speaker.

The controller performs a voice activated transmission (VOX) function using a user voice input to a microphone as an input signal.

The apparatus for transmitting and receiving voice according to another aspect may further include a communication module unit for transmitting and receiving a signal with an external device. In this case, the receiver receives a voice signal wirelessly or wired from an external device through the communication module unit, and the transmitter transmits the user voice wirelessly or wired through the communication module unit.

The controller may include a voice detector for detecting a user voice input from the microphone. In this case, when the user voice is detected by the voice detector, the controller performs a voice activated transmission (VOX) function to transmit a voice signal through the transmitter.

In the technology described below, transmission is accurately performed using earphones in which the microphone and the speaker are integrally implemented in the VOX voice transmitter.

That is, each process may occur in the same order as specified, may be performed substantially simultaneously, or may be performed in the reverse order.

Hereinafter, the voice transceiving apparatuses 100 and 200 will be described in detail with reference to the drawings. 1 is an example of a block diagram showing a configuration of a voice transceiving apparatus 100.

The voice transmitting and receiving device 100 of the present invention includes an antenna unit 150 including an antenna 152 for transmitting and receiving a wireless signal and a duplexer 151 for distinguishing a wireless signal being transmitted and received, and a voice of the other party transmitted from the antenna unit 150. Earphone type including a receiving unit 130 for receiving the user, a transmitting unit 120 for transmitting the user voice to the antenna unit 150, a microphone 111 for inputting the user voice, and a speaker 112 for outputting the other party's voice The control unit 140 detects a user's voice input to the voice input and output unit 110 and the voice input and output unit 110, and automatically transmits a voice signal through the transmitter 120.

The transmitter 120 includes a voice detector 121 for detecting a user voice input from the microphone 111, a voice modulator 122 for modulating the voice signal detected by the voice detector 121, and a modulated signal. It includes a wireless transmitter 123 for transmitting to the duplexer 151.

The speaker 112 is a dynamic speaker and may use a sealed armature speaker and / or a piezoelectric speaker to improve sound quality. This can reduce white noise.

The receiver 130 includes a wireless transmitter 132 for demodulating a voice signal by receiving a signal transmitted from the duplexer 151, and a voice amplifier 131 for amplifying the voice signal demodulated by the wireless transmitter 132.

The duplexer 151 is connected to the antenna 152 of the radio or the terminal to separate the transmission and reception frequency to prevent the crosstalk of the call.

The voice input / output unit 110 includes a microphone 111 for converting a voice signal transmitted from the user's ear canal into an electrical signal, a speaker 112 and a microphone 111 for transmitting the other party's voice received from the receiver 130 to the ear canal. And a housing part in the form of an earphone for accommodating 112.

The duplexer 151 outputs a high frequency signal received from the antenna 152 to the radio transmitter 132, and outputs a transmission frequency signal supplied from the radio transmitter 123 to the antenna 152.

The wireless transmitter 132 amplifies the high frequency signal supplied through the duplexer 151, makes it back to an intermediate frequency, detects and demodulates the intermediate frequency, and outputs the extracted voice signal to the voice amplifier 131.

The voice amplifier 131 amplifies a voice signal supplied through the wireless transmitter 132 and outputs the voice signal to the outside through the speaker 112.

The voice detector 121 detects a voice signal input through the microphone 111 and sends the voice signal to the voice modulator 122 if there is an input voice signal. The voice modulator 122 modulates the voice signal into a transmission frequency signal and outputs the voice signal to the wireless transmitter 123.

The radio transmitter 123 transmits a radio signal obtained by amplifying a transmission frequency signal modulated by the voice modulator 122 to the air through the duplexer 151 and the antenna 152.

The controller 140 performs a voice activated transmission (VOX) function using a user voice input to the microphone 111 as an input signal. The controller 140 detects a voice signal input from the microphone 111 of the voice input / output unit 110, and if the signal generated by the microphone 111 is a voice signal, automatically transmits the corresponding signal through the transmitter 120. do.

VOX refers to a function that detects and transmits a voice, and detects the sender's voice and transmits it automatically without pressing a push button (PTT). Especially when you are driving a car, a tank, etc., you can use both hands for other tasks or when you can't operate the radio.

In order to distinguish the noise generated from the microphone 111, a separate algorithm for recognizing a voice signal may be used, or a method for recognizing only a signal of a predetermined level or more as a voice signal may be used. However, since the voice input / output unit 110 in the present invention has a structure in which the microphone 111 is inserted into the ear in the form of an earphone, it can be easily distinguished whether it is voice or noise as compared to the prior art.

Therefore, a configuration in which the voice detection unit 121 is included in the control unit 140 without having the voice detection unit 121 in the transmitter 120 is also possible.

Meanwhile, the controller 140 may interpret the manipulation signal when the manipulation signal of the user is input through the external interface, and control the operation of each component of the voice transceiving device 100.

The voice transceiving apparatus 100 of the present invention may be used in a headset 111 microphone type apparatus used at a concert site, a voice transceiver used for construction sites or military purposes, and the like. The use of the voice transceiving device 100 according to the present invention should not be interpreted limitedly.

FIG. 2 is a diagram illustrating a state of use of the voice transceiving apparatus 100 and the voice input / output unit 110 of FIG. 1. 2 is a voice transceiving device 100 of the present invention. The voice input / output unit 110 in the form of an earphone is connected to the main body of the voice transceiving apparatus 100.

2 is a diagram illustrating a state in which the voice input / output unit 110 is used. The voice input / output unit 110 in the form of an earphone is inserted into a user's ear. Since the microphone 111 inserted into the ear canal is used, the voice transceiving device 100 of the present invention has a very low possibility of determining external noise as an input signal. The voice input / output unit 110 and the voice transceiver 100 may be connected by wire or wirelessly.

There are various types of earphones on the market. There are various forms such as a device that is inserted into only one ear in one piece, a device that is inserted into both ears in a single piece and a device that is in close contact with both ears in the form of a headset. Therefore, the voice input / output unit 110 according to the present invention may be manufactured in various forms as described above. However, as described above, the present invention is characterized in that the microphone 111 is not externally drawn out and is inserted into the ear integrally with the speaker 112.

3 is a flowchart illustrating an example in which the voice transceiving device 100 operates. 3 illustrates only a transmission mode in a voice transceiving device 100 such as a radio. Since the present invention relates to the voice transmitting and receiving device 100 using the VOX, a description of the reception mode is omitted.

When radio communication is started (510), the voice transceiver 100 determines whether the VOX mode is operating (520). That is, according to the embodiment, the user may set the VOX mode in advance. If the VOX mode is not set, it operates in the PTT mode as in a traditional radio (530).

When the voice transceiving device 100 operates in the VOX mode, it continuously monitors whether user voice is detected (540). If the user voice is detected, the user voice is automatically transmitted through the transmitter 120 (550). Thereafter, it is determined whether the radio communication is terminated (560), and if not, the radio communication is continuously performed.

4 is an example of another block diagram illustrating a configuration of the voice transceiving device 200. 4 does not have the antenna unit 150 unlike FIG. The voice transceiving device 200 of FIG. 4 illustrates a device connected to a separate external device 300 for receiving a voice signal. Here, the external device is a device that transmits a voice signal to the voice transceiving device 200 by wireless or wired or receives a voice signal input from the voice transceiving device 200. In this case, the voice transceiving device 200 of the present invention will correspond to a separate accessory device connected to a vehicle having a radio function, a military tank, or the like. Or it could be a control device that connects to a radio and gives the VOX function.

The voice transceiving device 200 illustrated in FIG. 4 includes a receiver 130 for receiving a voice of the other party transmitted from an external device, a transmitter 220 for transmitting a user voice to an external device, a microphone 211 for inputting a user voice, and Detects the user's voice input to the voice input / output unit 210 and the voice input / output unit 210 of the earphone type including a speaker 212 for outputting the other party's voice, and automatically transmits the voice signal through the transmitter 220. It includes a control unit 140 for transmitting.

Here, the receiver 230, the transmitter 220, and the voice input / output unit 210 may be the same as the voice transceiver 100 shown in FIG. 1.

The voice transceiving device 200 illustrated in FIG. 4 may further include a communication module 250 that transmits and receives a signal with the external device 300. In this case, the receiving unit 230 receives a voice signal from the external device 300 through the communication module 250 wirelessly or wired, and the transmitter 220 wirelessly or wires the user voice through the communication module 250. Can be transmitted to the external device 300.

The connection with the external device 300 is possible in various forms. It may be connected by wire or wirelessly. In the case of a wireless connection, various recently used near field communication (Near Field Communication, NFC) technology, Bluetooth communication technology, wifi communication technology or binary CDMA communication technology may be used. Currently, the most used technology in earphone devices is Bluetooth communication. In the present invention, the connection between the voice transceiving device 200 and the external device 300 is not limited to a specific form.

The controller 240 may also include a voice detector that detects a user voice input from the microphone 211. When the user voice is detected by the voice detector 221, the controller 240 performs a voice activated transmission (VOX) function to transmit a voice signal through the transmitter 220.

The embodiments and drawings attached to this specification are merely to clearly show some of the technical ideas included in the present invention, and those skilled in the art can easily infer within the scope of the technical ideas included in the specification and drawings of the present invention. Modifications that can be made and specific embodiments will be apparent that all fall within the scope of the present invention.
