Hereinafter, various embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of an electric guitar 100 according to an embodiment of the present disclosure.

The electric guitar 100 is a device that converts the resonant sound of a string into an electric signal using a magnetic pickup composed of a magnet and a coil and amplifies/outputs it to an amplifier, and may be an expression instrument that produces sound by plucking a string with a hand or a pick. However, it is not limited thereto, and the electric guitar 100 may be any guitar provided with an effector, a sensor, and the like, and capable of providing various interactions to the user. Here, the effector has a configuration that gives various effects to the sound of the electric guitar 100, and may be implemented in hardware inside the electric guitar 100. However, it is not limited thereto, and the effector may be implemented as one component of the processor of the electric guitar 100. Alternatively, the effector may be implemented in software or may be implemented in various forms. In FIG. 1 , for convenience of explanation, it is described that an effector is a component of a processor.

According to FIG. 1 , an electric guitar 100 includes a memory 110 , a sensor 120 and a processor 130 .

The memory 110 may refer to hardware that stores information such as data in an electrical or magnetic form so that the processor 130 or the like can access it. To this end, the memory 110 may be implemented with at least one hardware among non-volatile memory, volatile memory, flash memory, hard disk drive (HDD) or solid state drive (SSD), RAM, ROM, and the like. .

At least one instruction necessary for the operation of the electric guitar 100 or the processor 130 may be stored in the memory 110 . Here, the instruction is a code unit instructing the operation of the electric guitar 100 or the processor 130, and may be written in machine language, which is a language that a computer can understand. Alternatively, a plurality of instructions for performing a specific task of the electric guitar 100 or the processor 130 may be stored as an instruction set in the memory 110 .

The memory 110 may store data that is information in units of bits or bytes capable of representing characters, numbers, images, and the like. For example, information on a plurality of effectors may be stored in the memory 110 .

The memory 110 is accessed by the processor 130, and instructions, instruction sets, or data may be read/written/modified/deleted/updated by the processor 130.

The sensor 120 is a component for acquiring various information related to the electric guitar 100, for example, acquiring posture information and motion information of the electric guitar 100 or sound information of the electric guitar 100. can

The sensor 120 may include at least one of a gyro sensor, an acceleration sensor, a magnetometer sensor, or a sound sensor. The processor 130 may acquire posture information and motion information of the electric guitar 100 through a gyro sensor, an acceleration sensor, and a magnetometer sensor, and acquire sound information of the electric guitar 100 through a sound sensor.

The gyro sensor is a sensor for detecting the rotational angle of the electric guitar 100, and can measure the direction change of an object by using a property of always maintaining a predetermined direction set initially with high accuracy regardless of the rotation of the earth. The gyro sensor is also called a gyroscope, and may be implemented mechanically or optically using light.

The gyro sensor can measure angular velocity. Angular velocity means an angle rotated per time, and the measurement principle of the gyro sensor is as follows. For example, if the angular velocity is 0 degrees/sec in a horizontal state (stationary state) and then tilted by 50 degrees while moving for 10 seconds, the average angular velocity for 10 seconds is 5 degrees/sec. If the tilted angle of 50 degrees is maintained in the stationary state, the angular velocity becomes 0 degrees/sec. Through this process, the angular velocity changes from 0 → 5 → 0, and the angle increases from 0 degrees to 50 degrees. In order to get the angle from the angular velocity, we need to integrate over the whole time. Since the gyro sensor measures the angular velocity in this way, the tilt angle can be calculated by integrating this angular velocity over the entire time. However, the gyro sensor generates an error due to the influence of temperature, and the final value may drift as the error is accumulated during the integration process. Accordingly, the electric guitar 100 may further include a temperature sensor, and an error of the gyro sensor may be compensated for using the temperature sensor.

An acceleration sensor is a sensor that measures the intensity of acceleration or impact of the electric guitar 100, and is also called an accelerometer. The acceleration sensor detects dynamic forces such as acceleration, vibration, and shock, and may be implemented as an inertial type, a gyro type, a silicon semiconductor type, or the like, depending on a detection method. That is, the acceleration sensor is a sensor that senses the degree of inclination of the electric guitar 100 by using gravitational acceleration, and may typically be formed of a 2-axis or 3-axis fluxgate.

A magnetometer sensor generally refers to a sensor that measures the strength and direction of Earth's magnetism, but in a broad sense includes a sensor that measures the strength of magnetization of an object, and is also called a magnetometer. The magnetometer sensor may be implemented by suspending a magnet horizontally in a magnetic field and measuring a moving direction of the magnet, or measuring the strength of a magnetic field by rotating a coil in a magnetic field and measuring an induced electromotive force generated in the coil.

In particular, a geomagnetic sensor that measures the strength of the earth's magnetism as a type of magnetometer sensor may be generally implemented as a fluxgate-type geomagnetic sensor that detects the earth's magnetism using a fluxgate. A fluxgate type geomagnetic sensor uses a high magnetic permeability material such as permalloy as a magnetic core, and applies an excitation field through a driving coil wound around the magnetic core to generate magnetic saturation and nonlinear magnetic characteristics of the magnetic core. It refers to a device that measures the magnitude and direction of an external magnetic field by measuring the second harmonic component proportional to the external magnetic field. As the magnitude and direction of the external magnetic field are measured, the current azimuth is detected, and thus the degree of rotation can be measured. The geomagnetic sensor may be composed of a 2-axis or 3-axis fluxgate. A 2-axis fluxgate sensor, that is, a 2-axis sensor, means a sensor consisting of an X-axis fluxgate and a Y-axis fluxgate that are orthogonal to each other, and a 3-axis fluxgate, that is, a 3-axis sensor means a sensor with X-axis and Y-axis fluxgate on the Z-axis It means a sensor with fluxgate added.

Using the geomagnetic sensor and the acceleration sensor as described above, it is possible to acquire posture information of the electric guitar 100 . For example, attitude information of the electric guitar 100 may be expressed as a pitch angle, a roll angle, and an azimuth angle.

The azimuth angle (yaw angle) means an angle that changes in the left and right directions on a horizontal plane, and when the azimuth angle is calculated, it is possible to know which direction the electric guitar 100 is facing. For example, if a geomagnetic sensor is used, the azimuth can be measured through the following formula.

ψ = arctan(sinψ/cosψ)

Here, ψ denotes an azimuth, and cosψ and sinψ denote X-axis and Y-axis fluxgate output values.

The roll angle means an angle at which a horizontal surface is tilted from side to side, and when the roll angle is calculated, the left or right tilt of the electric guitar 100 can be known. The pitch angle refers to an angle at which a horizontal surface is tilted up and down, and when the pitch angle is calculated, the tilt angle at which the electric guitar 100 is tilted upward or downward can be known. For example, if an acceleration sensor is used, the roll angle and the pitch angle can be measured through the following equations.

φ=arcsin(ay/g)

θ=arcsin(ax/g)

Here, g is the gravitational acceleration, φ is the roll angle, θ is the pitch angle, ax is the X-axis acceleration sensor output value, and ay is the Y-axis acceleration sensor output value.

The sound sensor is a sensor that detects sound, and may be configured to detect vibration of a string, such as a Pick Up, and convert/transmit it into an electrical signal. However, it is not limited thereto, and the sound sensor may be implemented as a microphone or the like and may detect ultrasonic waves.

In the foregoing, for convenience of explanation, it has been described that the sensor 120 includes at least one of a gyro sensor, an acceleration sensor, a magnetometer sensor, and a sound sensor.

You can change the intensity of the effector of For example, if the motion information of the electric guitar 100 identified through the sensor 120 includes a predetermined motion, the processor 130 intentionally improves sound quality by using a clipping phenomenon caused by a high gain among a plurality of effectors. It is possible to improve the strength of the first effector for lowering and crushing. Alternatively, if the sound information of the electric guitar 100 identified through the sensor 120 includes the sound of sequentially playing a preset musical scale, the processor 130 may use a second effector that gives a resonant feeling in space among the plurality of effectors. strength can be reduced.

However, it is not limited thereto, and the electric guitar 100 is in a state in which two or more effectors are applied, and the processor 130 receives motion information of the electric guitar 100 or the sensor 120 identified through the sensor 120.

Hereinafter, the operation of the electric guitar 100 will be described in more detail with reference to FIGS. 3 to 15 . 3 to 15 describe individual embodiments for convenience of description. However, the individual embodiments of FIGS. 3 to 15 may be implemented in any combination.

As shown in FIG. 3 , the effector may be implemented as one component of the electric guitar 100 or as a separate hardware component from the processor 130 . In this case, the processor 130 may obtain motion information of the electric guitar 100 through the sensor 120 and transmit a control signal corresponding to the motion information to the effector based on the information stored in the memory 110 . That is, motion information of various patterns and corresponding operations may be stored in the memory 110 .

A sound corresponding to the performance of the electric guitar 100 may be provided to a speaker after an effector having a changed setting is applied.

However, it is not limited thereto, and the effector may be a component of the processor 130 or may be implemented in software and stored in the memory 110 .
