The controller 110 may generate a sensing signal corresponding to the change in the atmospheric pressure. The substrate may be a PCB (Printed Circuit Board).

3, when the user inputs an inspiration or an exhalation through at least one of the plurality of holes 10, the controller 110 controls the pressure sensors 121 of the pressure sensor unit 120 And determines whether the holes 10 are inhaled or exhaled according to the measured values to determine whether each of the holes 10 in which the atmospheric pressure change has occurred is measured, Generates sound signals according to preset sound information corresponding to any one of the inspiration and the exhalation based on the determination result, and generates MIDI information reproducible by the external device (2) based on the sound signals And transmits the generated data to the external device 2 through the communication unit 140.

Based on the above-described configuration, various configurations of the electronic harmonica according to the embodiment of the present invention will be described with reference to the drawings.

2 and 4, the substrate may be provided with a motion sensor unit 130 for sensing a movement of a user, and the control unit 110 may transmit a sensing signal according to the motion sensing of the user have.

Here, the motion sensor unit 130 may include various sensors for sensing movement of a user such as a gyro sensor, an acceleration sensor, a geomagnetism sensor, a proximity sensor, and a shock sensor.

The control unit 110 determines the direction of movement of the user based on the sensing signal of the motion sensor unit 130 and determines the direction of movement of the user based on one or more pieces of sound information corresponding to the sensing signal received from the air pressure sensor unit 120 And modulates the sound signals according to the setting information preset in the controller 110 in correspondence with the movement direction to generate a sound corresponding to the sound information in a semitone Or a modulated sound signal corresponding to a semitone-lowered sound.

As described above, the electronic harmonic according to the present invention can support the pitch adjustment conveniently according to the direction of movement of the user, thereby enhancing the convenience of playing.

1 to FIG. 2 and FIG. 5, the electronic harmonica may further include an operation unit 150 that receives user input and provides input information to the control unit 110.

The control unit 110 generates an acoustic signal corresponding to each of the at least one sound information selected according to the user's breath and then adjusts the frequency or volume of each acoustic signal based on the input information received from the operation unit 150 It is possible to generate a modulated sound signal and generate the MIDI information based on the modulated sound signal.

5, the operation unit 150 provides input information corresponding to the rotation input to the control unit 110, and the control unit 110 controls the operation unit 150 according to the rotation direction and the direction angle according to the input information.

Accordingly, the controller 110 maximizes the volume of the sound corresponding to the second sound signal b2 while removing the sound corresponding to the first and third sound signals b1 and b3 as much as possible, Can be output through the device.

7, when the sensing signal of the air pressure sensor unit 120 is received, the controller 110 selects the second switch 162 from the plurality of switches included in the switch unit 160, (B1, b3) other than the second sound signal (b2) having the largest change in the atmospheric pressure among the first to third sound signals (b1, b2, b3) B2, and b3, and then generates the MIDI information by synthesizing the first to third sound signals b1, b2, and b3.

Accordingly, the controller 110 amplifies the sound levels of the first and third sound signals b1 and b3 to a level similar to the sound level of the second sound signal b2 to generate MIDI information for the chord sound .
