The human body communication module 116 modulates the data received from the controller 180 for human body communication and outputs the modulated signal to two human body contacted electrodes through the switch 310. In addition, the human body communication module 116 demodulates signals received from two human body contact electrodes for human body communication, and transmits the demodulated data to the controller 180. The modulation for human body communication may be frequency modulation (FM). Demodulation for human body communication may be demodulation corresponding to FM.

Next, the noise filter 200 according to various embodiments of the present disclosure will be described with reference to FIGS. 9 through 12.

Unlike ECG-only equipment, the mobile terminal 100 is exposed to various noise environments. For example, when measuring the ECG through the mobile terminal 100, a text message or a call may come, and at this time, a notification sound, a ringtone, and a vibration may be noise of the ECG signal. In addition, the user may measure the ECG to check his or her health or record the current emotional state while moving, listening to music, watching a video, or at a concert, where the shaking of the mobile terminal 100 may occur. Noise or noise due to music reproduction may occur. Noise due to static electricity in winter may occur, and noise of 60 Hz frequency may occur due to the influence of AC AC power when charging the mobile terminal 100.

As such, when measuring ECG through the mobile terminal 100, a noise filter that can be applied to various noise environments is required.

In particular, when the controller 180 detects the reception of a text message or a call when measuring the ECG through the ECG sensor 142c, the controller 180 can turn off the alarm unit 153.

The noise detector 220 detects noise in the digital electrocardiogram signal. The detected noise may be a noise signal on the time axis or a noise frequency pattern on the frequency axis.

The noise remover 230 removes noise detected from the digital electrocardiogram signal. In particular, when the noise detector 220 detects a noise signal, the noise remover 230 may correspond to a subtractor that subtracts the noise signal from the digital electrocardiogram signal. In addition, when the noise detector 220 detects a noise frequency pattern, the noise remover 230 may be a notch filter that blocks the noise frequency pattern detected in the digital electrocardiogram signal.

The vibration sensor detects vibration and outputs a noise source signal corresponding to the vibration detection signal. The electromagnetic sensor detects electromagnetic waves and outputs a noise source signal corresponding to the electromagnetic wave detection signal. The sound source detector detects a sound source to be reproduced and outputs a noise source signal corresponding to the sound source signal.

Noise due to static electricity in winter or noise at 60 Hz during charging of the mobile terminal 100 may be removed through the noise filter as shown in FIG. 11.

12 is a block diagram of a noise filter according to another embodiment of the present invention.

Next, an ear jack type photoplethysmographic signal (PPG) sensor (hereinafter referred to as a PPG sensor) and a mobile terminal 100 supporting the same will be described with reference to FIGS. 13 and 14.

13 shows an earjack type PPG sensor according to an embodiment of the present invention.

As shown in FIG. 13, the earjack type PPG sensor 142b according to the embodiment of the present invention includes a light emitting diode 172, a light receiving diode 173, and a current-voltage converter (IV converter) ( 720, filter 730, amplifier 735, plug 740. The plug includes a microphone signal port 740a, a first ear speaker port 740b, a second ear speaker port 740c, and a ground port 740d.

The anode terminal of the light emitting diode 172 is connected to the second ear speaker port 740c, and the cathode terminal is connected to the ground port 740d. An anode terminal and a cathode terminal of the light receiving diode 173 are respectively connected to two input terminals of the current-voltage converter 720. The output terminal of the current-voltage converter 720 is connected to the input terminal of the filter 730. The output terminal of the filter 730 is connected to the input terminal of the amplifier 735. The output terminal of the amplifier 735 is connected to the microphone signal port 740a.

14 is a block diagram illustrating additional components of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 14, a mobile terminal 100 according to an embodiment of the present invention includes an ear jack 176, an audio subsystem 240, an analog-to-digital converter 250, and a switch 260. The ear jack 176 includes a microphone signal port 176a, a first ear speaker port 176b, a second ear speaker port 176c, and a ground port 176d.

The input terminal of the analog-to-digital converter 250 is connected to the microphone signal port 176a. The output terminal of the analog-digital converter 250 is connected to the controller 180. One end of the switch 260 is connected to the microphone signal port 176a and the other end is connected to the microphone signal input terminal of the audio subsystem 240. The first ear speaker port 176b and the second ear speaker port 176c are respectively connected to two audio output terminals of the audio subsystem.

In order for the ear jack 176 to be normally used for audio, the controller 180 provides a control signal to the switch 260 such that the switch 260 is turned on.

When the plug 740 is inserted into the ear jack 176, the microphone signal port 740a, the first ear speaker port 740b, the second ear speaker port 740c, and the ground port 740d may each be a microphone signal port ( 176a, the first ear speaker port 176b, the second ear speaker port 176c, and the ground port 176d.

Then, the light emitting diode 172 emits light by the initial voltage applied to the second ear speaker port 176c.

Meanwhile, the current-voltage converter 720, the filter 730, and the amplifier 735 operate abnormally due to the initial voltage applied to the first ear speaker port 176b. That is, the light receiving diode 173 receives the light emitted by the light emitting diode 172 and generates a current signal. The current-voltage converter 720 converts the generated current signal into a voltage signal by the initial voltage. The filter 730 filters the voltage signal by the initial voltage to generate a filtered voltage signal. Amplifier 735 amplifies the voltage signal filtered by the initial voltage to generate an initial PPG signal.

This initial PPG signal is not an accurate blood motion measurement signal but raises the DC level of the microphone signal port 176a.

The ADC 250 converts the initial PPG signal into digital and provides it to the controller 180.

When the controller 180 detects the DC level rise of the microphone signal port 176a, the controller 180 recognizes that the PPG sensor 142b is inserted into the ear jack 176. And, in order for the ear jack 176 to be used for the PPG sensor 142b, the controller 180 provides a control signal to the switch 260 so that the switch 260 is turned off.

Meanwhile, in order to provide stable power to the PPG sensor 142b, the controller 180 controls the audio subsystem 240 so that the audio subsystem 240 includes the first ear speaker port 176b and the second ear speaker port ( Provide a DC voltage to 176c).

When the PPG sensor 142b is supplied to a stable power source, the light emitting diode 172 normally emits light due to the DC voltage applied to the second ear speaker port 740c. In addition, the current-voltage converter 720, the filter 730, and the amplifier 735 operate normally by the DC voltage applied to the first ear speaker port 740b. Therefore, the amplifier 735 provides a normal blood motion measurement signal to the microphone signal port 740a, and the ADC 250 converts the normal blood motion measurement signal into a digital signal and provides it to the controller 180.
