Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is an external view of an anodizing electronic musical instrument according to an embodiment of the present invention. An electronic musical instrument according to an embodiment of the present invention is an electronic device that reproduces and outputs a percussion instrument such as a drum, a xylophone, and a sound of a rhythm instrument such as Tambourine or Maracas, an animal, or a bird.

In addition, the dual play means that an additional sound output, which is generated according to the characteristic of the musical instrument, is added to the sound output according to the user's operation. That is, the electronic musical instrument outputs a sound twice in one beat in the course of the direction change by the user by hitting or shaking.

As shown in FIG. 1, a speaker for sound output is provided at an upper portion of the electronic musical instrument according to an embodiment of the present invention, and a user operation means is provided at a central portion.

The electronic musical instrument according to the embodiment of the present invention is different from the electronic musical instrument according to the embodiment of the present invention in that the output sound is different when hitting (Fig. 2) and shaking (Fig. 3), and when a thumb is touched to the sound source alternate T- When it is not, the sound output is different.

Also, the output sounds when the preset use mode switch is on and off are different from each other, and the output sound differs depending on which one of the six selection buttons "1" to "6" is highlighted in FIG.

Here, a different sound means that the sound source is different, that is, the sound of each different instrument, the animal / bird sound is output.

FIG. 5 illustrates combinations of sounds output according to a combination of On / Off state of the preset use mode switch, a number selected by the selection button, whether or not the T-sensor is touched, and a wiggle / strike. In addition, the theme (theme) of each combination is shown.

In Fig. 5, shaking 1 is a case of touching a sensor and shaking an electronic musical instrument, and shaking 2 is a case of shaking an electronic musical instrument without touching a sensor. Also, blow 1 is a case of touching a sensor and blowing an electronic musical instrument, and blow 2 is a case of hitting an electronic musical instrument without touching a sensor.

The combination illustrated in FIG. 5 is a combination provided basically at the time of shipment of the product, and it is possible to add / change / delete the combination according to the taste of the user in the future.

6 is an internal block diagram of a bipolar electronic musical instrument according to an embodiment of the present invention. 6, an electronic musical instrument according to an embodiment of the present invention includes an acceleration sensor 110, a user operation unit 120, a processor 130, a sound source storage unit 140, a DAC 150, An amplification unit 170, and a speaker 180. The amplification unit 170 amplifies the amplified signal.

The acceleration sensor 110 measures the motion of the electronic musical instrument by the user and transmits the measured motion information to the processor 130.

The user operation unit 120 includes the above-described sound source alternate T-sensor, a preset use mode switch, a selection button, and the like. The contents of the operation of the user through these are transmitted to the processor 130.

The processor 130 determines the output sound source and the output time through the user operation through the user operation unit 120 and the motion analysis through the acceleration sensor 110. [

The types of output sound sources are as follows: 1) On / Off state of the preset use mode switch 2) Number selected by the selection button 3) Whether the T-sensor is touched or not 4) .

Here, "1)" to "3)" are determined by user manipulation through the user manipulation unit 120, and "4)" is determined through motion information analysis generated by the acceleration sensor 110.

The output timing is determined so that sound is output twice in one beat to satisfy the above-described anodic performance scheme.

Specifically, 1) sound is firstly output at the time of hitting or swinging direction of the electronic musical instrument, and 2) sound is output at a second time when a specific time elapses.

"1)" is a musical instrument sound output according to a user's operation, and "2)" is an incidental sound output generated according to characteristics of the musical instrument. The sound volume of "2)" is set to be smaller than the sound volume of "1)", and in the case of the drum sound, the sound of "

More specifically, the sound volume of "2)" may be 1/2, 1/3, 1/4 of the sound volume of "1)". On the other hand, all of the numerical values presented are exemplary and can be generalized to 1 / M (M > 1).

In the above "1)", the point in time at which the electronic musical instrument hit or shake direction is switched will correspond to one beat, and thus the interval between hit / switch points corresponds to the length of one beat.

The point at which the sound of "2)" is output is set to 1/2, 1/3, 1/4 of the interval between the batting / switching points (length of one beat) Can be calculated by adding or subtracting an arbitrary time to these values. On the other hand, all of the numerical values are exemplary and can be generalized to 1 / N (N> 1) depending on the type of musical instrument.

7 shows the points at which the primary sound is output by the "1)" and the points at which the secondary sound by the "2)" are output to the motion information generated by the acceleration sensor 110, respectively.

On the other hand, when the first electronic musical instrument strikes and wiggles are switched, the interval between hit / switch points can not be known. In this case, the second sound output point is initially set to a default value (for example, 0.3 second).

The processor 130 reads the sound source from the sound source storage unit 140 and outputs the read sound source to the DAC 150 at the time of outputting the sound source to be output. The digital sound source is D / A converted into an analog signal by the DAC 150.

In addition, the processor 130 controls the volume control unit 160 to adjust the sound volume. The audio signal whose volume has been adjusted by the volume controller 160 is amplified by the amplifier 170 and output through the speaker 180.

Up to now, a preferred embodiment of a bipolar electronic musical instrument has been described in detail.

In the above embodiment, it is assumed that the sound of the musical instrument first outputted according to the user's manipulation and the musical instrument sound secondaryly output according to the characteristic of the musical instrument are the same sound source and only the sound magnitude is different.

However, this is only an example. It is also possible to implement a musical instrument sound to be firstly outputted and a musical instrument sound to be secondarily outputted by another sound source.

Furthermore, in the above embodiment, the secondary output is performed at a time point when a specific time elapses from the time when the electronic musical instrument strikes or wiggles are switched by the user.

For example, the secondary output can be implemented so that the secondary output is performed when the motion state (size / direction) satisfies a specific condition, for example, when the motion size is increased by 25% from the minimum value.

Furthermore, as shown in FIG. 6, the electronic musical instrument input device 100a for motion measurement and user manipulation and the electronic musical instrument output device 100b for sound output wirelessly communicate with each other to implement a bipolar electronic musical instrument system It goes without saying that the technical idea of the present invention can be applied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
