본 발명은 휴대용 전화기가 사용되는 차량용 핸즈프리장치에 관한 것으로서, 차량속도의 증감에 따라 핸즈프리장치의 볼륨이 자동으로 업/다운(UP/DOWN) 조절되도록 하여 사용상 편리성 및 안전성을 높힌 속도 감응에 의한 자동볼륨 핸즈프리장치 및 그 방법에 관한 것이다.The present invention relates to a hands-free device for a vehicle in which a portable telephone is used, and the volume of the hands-free device is automatically adjusted up / down according to the increase or decrease of the vehicle speed. An automatic volume hands free device and a method thereof are provided.

도 1은 종래의 핸즈프리장치의 구성도이다. 이러한 핸즈프리장치는 마이크(1)로 사용자의 음성이 입력되면 증폭시킨 후 음성신호 처리부(2)에서 통화품질을 높히기 위하여 음성신호를 처리하여 핸드폰(3)으로 전달하며, 핸드폰(3)으로부터 수신된 음성신호도 동일하게 음성신호 처리부(2)에서 처리된 후 볼륨 조절부(4)에서 볼륨이 조절되고 음성신호 증폭부(5)에서 신호가 증폭되어 스피커(6)로 출력하도록 이루어진다. 따라서, 운전자는 핸드폰(3)을 손에 들지 않고도 통화를 수행할 수 있으나, 운전자가 직접 차량을 운전하다 보면 차량의 주행정도에 의하여 실내부에 필연적으로 소음이 발생하게 되는데, 이러한 실내에 형성된 소음으로 인하여 스피커(4)로부터 출력되는 소리가 정확히 전달되지 않아 운전자는 정상적인 통화를 하는데 방해를 받게 된다.1 is a block diagram of a conventional hands-free device. The hands-free device amplifies when a user's voice is input into the microphone 1 and processes the voice signal to the mobile phone 3 to increase the call quality in the voice signal processing unit 2 and receives the received voice from the mobile phone 3. Likewise, the voice signal is processed by the voice signal processor 2, and then the volume is adjusted by the volume controller 4, and the signal is amplified by the voice signal amplifier 5 to be output to the speaker 6. Therefore, the driver can perform a call without holding the mobile phone 3, but when the driver directly drives the vehicle, noise is inevitably generated in the interior according to the driving degree of the vehicle. Due to this, the sound output from the speaker 4 is not transmitted correctly, and the driver is prevented from making a normal call.

이에, 운전자는 소음의 양에 따라 볼륨을 올리거나 내리기 위해 손을 뻗어 핸드폰의 볼륨키 등으로 이루어진 볼륨조절부(4)를 조작해야만 하게 되는데, 이는 상기와 같은 종래의 핸즈프리장치를 사용하는데 있어서 불편함을 유발할 뿐만아니라 운전자의 한 손이 핸들을 벗어나게 되고 운전의 집중력을 떨어뜨리게 하여 안전운전을 방해하게 되는 위험성을 내포하고 있는 문제점이 있다.Accordingly, the driver has to operate the volume control unit 4 consisting of the volume keys of the mobile phone, etc. by reaching out to raise or lower the volume according to the amount of noise, which is inconvenient in using the conventional hands-free device as described above. In addition to causing the injuries, there is a problem that one hand of the driver is off the steering wheel and the concentration of driving lowers the concentration of driving, which impairs the safe driving.

상기된 바와 같은 문제점을 해결하기 위하여 본 발명의 목적은 차량 실내소음의 크기에 직접적인 원인이 되는 속도의 증감에 대하여 핸즈프리장치에서 볼륨이 자동 조절되도록 하여 통화의 편의성을 향상시키고 안전운전을 가능하게 하는 속도 감응에 의한 자동볼륨 핸즈프리장치 및 그 방법을 제공하는데 있다.In order to solve the problems as described above, an object of the present invention is to automatically adjust the volume in the hands-free device to increase or decrease the speed that directly causes the noise of the vehicle interior to improve the convenience of the call and enable safe driving The present invention provides an automatic volume hands-free device and a method thereof.

상기의 목적을 달성하기 위하여, 본 발명에 따른 속도 감응에 의한 자동볼륨 핸즈프리장치는 운전자가 차량운행중에 휴대폰으로 통화를 실시중일 때 차량 내에 기장착되어 있는 속도센서로부터 감지된 속도의 증감에 따라 스피커로 출력되는 소리에 대한 볼륨이 자동으로 업/다운(UP/DOWN) 조절되도록 이루어진 것을 특징으로 한다.In order to achieve the above object, the speed-sensitive automatic volume hands-free device according to the present invention is a speaker according to the increase or decrease of the speed detected from the speed sensor mounted in the vehicle when the driver is talking on the mobile phone while driving the vehicle. It is characterized in that the volume for the sound output to the automatic adjustment up / down (UP / DOWN).

이하, 본 발명에 따른 속도 감응에 의한 자동볼륨 핸즈프리장치의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the automatic volume hands free device according to the speed-sensitive according to the present invention will be described in detail.

도 2는 본 발명에 따른 속도 감응에 의한 자동볼륨 핸즈프리장치를 나타내는 구성도이다.2 is a block diagram showing an automatic volume hands-free device according to the speed response according to the present invention.

상기와 같은 특징을 갖는 본 발명에 따른 속도 감응에 의한 자동볼륨 핸즈프리장치(50)는 핸드폰(10)이 설치되고 차량의 전원(30)으로 작동되도록 이루어진 핸즈프리장치(50)에 있어서, 마이크(52)와 핸드폰(10)으로부터 입력되는 음성신호를 처리하여 각각 핸드폰(10)과 스피커(51)측으로 전달하는 음성신호 처리부(53)와, 차량의 속도센서(20)로부터 감지된 속도신호를 연산처리하는 연산부(54)와, 감지된 속도를 기반으로 볼륨을 자동 조절하는 볼륨조절부(55)와, 스피커(51)로 출력을 위해 음성신호를 증폭하는 음성신호 증폭부(56)로 구성된다.The automatic volume hands-free device 50 according to the speed-sensitive according to the present invention having the above characteristics has a microphone 52 in the hands-free device 50 in which the cellular phone 10 is installed and operated by the power supply 30 of the vehicle. ) And a voice signal processing unit 53 for processing the voice signal input from the mobile phone 10 and delivered to the mobile phone 10 and the speaker 51, and the speed signal detected by the speed sensor 20 of the vehicle. Comprising a calculation unit 54, a volume control unit 55 for automatically adjusting the volume based on the sensed speed, and a voice signal amplification unit 56 for amplifying the voice signal for output to the speaker 51.

여기서 음성신호 처리부(Audio signal Processing unit)라 함은, 예를 들어 디에스피(DSP: Digital Signal Processing, 디지털 신호처리)가 있는데, 이는 수신기의 감도를 극적으로 개선한 것으로서 잡음과 요구되는 신호가 경합할 때 S/N비를 개선시키게 된다. 처음에 입력되는 신호가 ADC(A/D 변환기)에 의해 디지털 신호로 변환되며, 이 디지털 신호의 레벨을 DSP회로가 조정함으로서 실제로 잡음을 제거하게 되고, 이후 디지털 신호는 DAC(D/A 변환기)를 통해 다시 아날로그 신호로 변환된다.The audio signal processing unit is, for example, DSP (Digital Signal Processing), which dramatically improves the sensitivity of the receiver. When the S / N ratio is improved. The first input signal is converted into a digital signal by an ADC (A / D converter), and the DSP circuit adjusts the level of the digital signal to actually remove noise, and then the digital signal is a DAC (D / A converter). Is converted back to an analog signal.

이와 같은 음성신호 처리는 상기 디에스피 뿐만아니라 하프 듀플렉스(HalfDuplex) 또는 이와 다른 여러 방법으로 구현이 가능하다.Such voice signal processing may be implemented not only by the DSP, but also by a half duplex or other various methods.

차량에 기설치되어 있는 속도센서(20)는 차량의 속도를 감지하여 속도신호를 발생시키게 되며, 상기 연산부(54)는 속도센서(20)로부터 상기 속도신호를 수신한 후 수신된 속도신호를 연산처리하여 볼륨조절신호를 발생시키게 된다. 이 볼륨조절신호는 후에 볼륨을 자동 조절하기 위한 신호가 된다.The speed sensor 20 installed in the vehicle detects the speed of the vehicle to generate a speed signal, and the calculation unit 54 calculates the received speed signal after receiving the speed signal from the speed sensor 20. Processing to generate a volume control signal. This volume control signal is a signal for automatically adjusting the volume later.

볼륨은 속도구간에 따라 정해질 수 있으며 이에 따른 실시예로서, 시속 0∼59㎞일 때 볼륨 1, 시속 60∼69㎞일 때 볼륨 2, ... , 시속 100∼110㎞일 때 볼륨 6, 시속 110㎞이상일 때 볼륨 7로 설정된 후, 각 속도 구간에 대하여 해당 볼륨 크기로 스피커(51)를 통하여 출력이 이루어지도록 실시할 수 있으며, 사용자의 설정에 따라 다양하게 적용가능하다.The volume may be determined according to the speed section, and as an example, the volume 1 at 0 to 59 km / h, the volume 2 at 60 to 69 km / h, and the volume 6 at 100 to 110 km / h After setting the volume 7 when the speed is 110 km or more, the output may be performed through the speaker 51 at the corresponding volume level for each speed section, and may be variously applied according to the user's setting.

또한, 부가적으로 상기 연산부(54)는 기준속도(예를 들어, 규정속도 또는 사용자에 의해 설정된 속도) 이상에서 경고음 또는 경고멘트를 출력하기 위한 경고신호를 발생하는데, 이는 볼륨조절신호 발생을 위한 연산부(54)의 처리와는 독립된 처리로서 기준속도 이상에서 발생되는 경고신호는 음성신호 증폭부(56)에 전달되고, 이에 상기 음성신호 증폭부(56)는 경고음 또는 경고멘트를 출력하게 되는데, 예를 들어 기준속도를 시속 100㎞ 로 설정했을 때 운행속도가 100㎞ 이상이 되면 경고음은 "삐삐삐", 경고멘트는 "속도를 줄이세요"라는 경고성 신호를 스피커를 통하여 출력되도록 처리하게 된다.In addition, the calculation unit 54 generates a warning signal for outputting a warning sound or a warning message at a reference speed (for example, a predetermined speed or a speed set by a user), which is used for generating a volume control signal. As a process independent of the processing unit 54, a warning signal generated at a reference speed or higher is transmitted to the voice signal amplifying unit 56, and the voice signal amplifying unit 56 outputs a warning sound or a warning message. For example, when the reference speed is set to 100km / h, when the driving speed is over 100km, the warning sound "beep beep" and the warning message "low speed" will be output through the speaker. .

상기 연산부(54)에서 발생되는 볼륨조절신호는 전자볼륨장치 등에 의해 종래 수동 볼륨스위치 방식과는 달리 전자적으로 처리되는 볼륨조절부(55)로 전송되며, 이 볼륨조절부(55)는 수신한 볼륨조절신호를 처리하여 음성신호 증폭부(56)에서 증폭한 후 스피커(51)로 출력되는 볼륨을 자동 조절하게 된다. 즉, 차량의 속도가 증가하면 이에 대응되는 볼륨조절신호에 의해 볼륨을 크게 조절하고 속도가 감소하면 볼륨을 작게 조절하는 것이다. 보다 상세하게, 볼륨이 자동 조절되는 과정은 아래에서 설명된다.The volume control signal generated by the calculation unit 54 is transmitted to the volume control unit 55 which is electronically processed unlike the conventional manual volume switch method by an electronic volume device, and the volume control unit 55 receives the received volume. After processing the control signal and amplified by the voice signal amplifier 56, the volume output to the speaker 51 is automatically adjusted. In other words, when the speed of the vehicle increases, the volume is controlled by the volume control signal corresponding to the increase, and when the speed decreases, the volume is reduced. In more detail, the process of automatically adjusting the volume is described below.

도 3은 본 발명에 따른 속도 감응에 의한 핸즈프리장치의 자동볼륨 조절방법을 나타낸 순서도이다.Figure 3 is a flow chart illustrating a method for automatically adjusting the volume of the hands-free device by the speed response according to the present invention.

This reference speed is the speed used as the reference for the alarm sound output as described above. This initial setting may be made by a user or may be set as a default setting when manufacturing a product.

자동볼륨 조절기능을 사용하는 경우에, 통화시도키가 입력되면서 통화가 실시되며(S2), 통화중에 속도센서(20)로부터 속도를 체크하고 감지된 속도신호를 발생시킨다(S3).In the case of using the automatic volume control function, the call is initiated while the call attempt key is input (S2), the speed is checked from the speed sensor 20 during the call and the detected speed signal is generated (S3).

상기 속도감지단계(S3)로부터 발생된 속도신호는 연산부(54)에서 연산처리하게 되며(S4), 이 연산단계(S4)는 수신된 속도신호에 해당되는 볼륨조절신호를 출력한다.The speed signal generated from the speed detection step S3 is processed by the calculation unit 54 (S4), and this calculation step S4 outputs a volume control signal corresponding to the received speed signal.

이 볼륨조절신호는 볼륨조절부(55)로 입력되며, 볼륨조절단계(S5)는 상기 볼륨조절신호에 해당하는 볼륨을 자동조절하여 음성신호 증폭부(56)로 전달하며, 이후 증폭된 음성신호는 스피커(51)로 출력된다.The volume control signal is input to the volume control unit 55, and the volume control step (S5) is automatically adjusted to the volume corresponding to the volume control signal and delivered to the voice signal amplifier 56, and then amplified voice signal Is output to the speaker 51.

도 4는 본 발명에 따른 속도 감응에 의한 핸즈프리장치의 경고음 출력방법을 나타낸 순서도이다.Figure 4 is a flow chart illustrating a warning sound output method of the hands-free device according to the speed response according to the present invention.

In operation S6, when the vehicle speed is equal to or greater than the reference speed, the warning sound or the warning message as described above is output in the warning sound output step S7.

이렇게 볼륨이 조절되는 것은 속도센서(20)로부터 실시간으로 전달되는 속도신호에 대응하여 통화중에 계속적으로 볼륨이 자동조절되는 동일과정을 반복수행하게 된다.In this way, the volume is controlled to perform the same process of automatically adjusting the volume continuously during the call in response to the speed signal transmitted from the speed sensor 20 in real time.

또한, 주위 소음에 대하여 알맞는 통화볼륨을 제공하므로서, 최적의 통화품질을 확보하도록 하는데 효과가 있다.In addition, by providing a suitable call volume against the ambient noise, it is effective to ensure the optimum call quality.

뿐만아니라, 설정된 기준속도 이상에서 경고음 또는 경고성 멘트를 스피커(51)로 출력하여 운전자에게 경고하므로서 과속운전에 의한 교통사고를 예방하는데 효과가 있다.In addition, by outputting a warning sound or warning message to the speaker 51 at a set reference speed or more, it is effective in preventing traffic accidents caused by overspeed driving.
