The performance assisting tool 10 includes a tapping plate 101, a first sensor 102a and a second sensor 102b, an output unit 103, and a detachable structure 104.

In the present embodiment, the case where the stringed instrument having no resonance cylinder to which the performance assisting tool 10 is attached is the guitar 20 will be described. The sound box is, for example, a hollow body of a stringed instrument. Here, the guitar 20 is provided on the head 201, the neck 202, the body 203 having no block-shaped hollow structure attached on the extension of the neck 202, the strings 204, and the side surface side of the body 203. A case will be described in which a frame 206 having a shape similar to that of the side surface of the resonance body of a general acoustic guitar is provided. The portion of the body 203 that fastens one end of the string 204 is called a bridge 205. However, it does not have to have the frame body 206. The shape of the body 203 of the guitar 20 is preferably a columnar shape whose longitudinal direction coincides with the longitudinal direction of the guitar 20 in order to reduce the weight of the guitar 20. Here, the body 203 shows an example in which the portion near the bridge 205 has a columnar shape bulging in the width direction. Further, the width of the body 203 may be at least the minimum size that can be held by fastening the end of the string 204 of the guitar 20 opposite to the head 201. The guitar 20 has a pickup (not shown) for acquiring an electric signal which is a sound signal from the vibration of the string 204 and the vibration of the body 203 and the like, and for outputting the electric signal acquired by the pickup to the outside. It may or may not have an output terminal (not shown), an amplifier (not shown) that amplifies the electric signal acquired by the pickup, and the like. The structure of the guitar 20 having no resonance cylinder is not limited to the structure shown in FIG. Since a guitar having no sound box is known, detailed description thereof will be omitted here.

The tapping plate 101 is attached to the guitar 20. The tapping plate 101 is a plate for a player of the guitar 20 (hereinafter referred to as a user) to tap. Hitting is hitting. The tapping of the tapping plate 101 is usually performed by hand. The material of the tapping plate 101 may be wood, resin, metal, or a combination thereof. However, the material of the tapping plate 101 is not limited to these. The surface 101a of the tapping plate 101 is usually flat, but may not be flat. The surface 101a of the tapping plate 101 is the surface on the same side as the side on which the string 204 of the guitar 20 is attached. The planar shape of the tapping plate 101 and the size and thickness in the planar direction do not matter. The tapping plate 101 may have a planar shape and a size in the planar direction that are easy for the user to tap. Here, an example is shown in which the tapping plate 101 has a side having a shape along the side surface of the body 203 of the guitar 20 at a portion attached to the guitar 20. Further, here, an example is shown in which a part of the tapping plate 101 is arranged on the frame body 206. However, the tapping plate 101 does not have to be arranged on the frame body 206. The tapping plate 101 may or may not be hollow inside.

In order to hit the tapping plate 101 while playing the guitar 20, it is preferable that the tapping plate 101 is attached in the vicinity of the portion where the user of the guitar 20 plays the string 204. In particular, when striking the striking plate 101 with the same one-handed wrist or ball while playing the string 204 of the guitar with the fingers of one hand without moving the position of the hand as much as possible, the mounting position of the striking plate 101 is shown in the figure. As shown in 1, the front side of the guitar 20 is preferable, and the front side of the position where the string 204 of the guitar 20 is played is more preferable. The front side here is, for example, the side above the string 204 when the user holds the guitar 20 so that the head 201 is located on the left side, or the side where the arm playing the user's string 204 is located. be. However, the position where the tapping plate 101 is attached to the guitar 20 is not limited to this. For example, the tapping plate 101 may be attached to the back side of the guitar 20. The back side of the guitar 20 is, for example, the side located opposite to the front side of the guitar 20 with the string 204 of the guitar 20 in between. The back side of the guitar 20 is, for example, the side below the strings 204 when the user holds the guitar 20 so that the head 201 is located on the left side. The tapping plate 101 is attached to the side surface of the body 203 of the guitar 20. However, the tapping plate 101 may be attached to a portion other than the body 203, for example, the frame body 206 or the like, or may be attached to both the body 203 and the frame body 206. Note that playing the string 204 while hitting may mean playing the string 204 between hits, playing the string 204 at the same time as hitting, or a combination of these. good. Further, playing the string 204 while hitting may mean playing so as to include hitting and playing the string 204.

The tapping plate 101 has a detachable structure 104 that can be attached to and detached from the guitar 20, and is detachably attached to the guitar 20 by the detachable structure 104. The detachable structure 104 includes an L-order metal fitting 1041 bent in a direction away from the tapping plate 101, which is attached to the back surface 101b side of the side of the tapping plate 101 having a shape along the side surface of the body 203 of the guitar 20 described above. It is composed of two sets of a knob screw 1042 for fastening the L-order metal fitting 1041 to the side surface of the body 203 of the guitar 20. By fastening the above screw 1042 to a screw hole (not shown) provided on the side surface of the body 203 of the guitar 20 with the knob screw 1042, the tapping plate 101 is detachably attached and fixed to the side surface of the body 203. be able to. The attachment / detachment structure of the tapping plate 101 is not limited to the above attachment / detachment structure 104. For example, the detachable structure may have only one of the above sets, or may have a plurality of the above sets. For example, the detachable structure may be a pin provided on the side surface of the tapping plate 101 or the like, which fits into one or more holes provided on the side surface of the body 203. The pins and holes may have a locking structure so that they do not come off easily. The detachable structure may be a rail or the like provided on the side surface of the tapping plate 101 or the like that can be slid and fitted into one or more grooves provided on the side surface of the body 203. Further, the detachable structure may be a band or a belt that can be wound around the body 203. By making the tapping plate 101 removable from the guitar 20, the tapping plate 101 can be removed when the tapping plate 101 is not used.

The tapping plate 101 does not have to be detachably attached to the guitar 20. For example, the tapping plate 101 may be fixed to the guitar 20. For example, the tapping plate 101 may be adhered to the guitar 20 with an adhesive or the like, or may be fastened with a wood screw, a nail, or the like.

The first sensor 102a and the second sensor 102b are sensors that detect information regarding tapping on the tapping plate 101. The information regarding the tapping detected by the first sensor 102a and the second sensor 102b may be, for example, information indicating whether or not the tapping plate 101 has been tapped by the user, and the information corresponding to the tapping strength. May be. The first sensor 102a and the second sensor 102b may be, for example, sensors that detect whether or not they have been hit and output information indicating whether or not they have been hit, depending on the strength of the hit. It may be a sensor that acquires information and outputs information according to the acquired strength (for example, a numerical value indicating strength). The first sensor 102a and the second sensor 102b may be, for example, a sensor that detects the strength of being struck and outputs a signal or the like whose signal strength becomes stronger according to the detected strength. The first sensor 102a and the second sensor 102b are attached to the tapping plate 101, for example, and have a vibration sensor that detects the vibration of the tapping plate 101 when tapped, or a pressure applied to the tapping plate 101 when tapped. It is a combination of two or more of these, such as a pressure sensor that detects a pressure sensor, a sensor that detects a sound generated when the tapping plate 101 is hit, a distortion sensor that detects the distortion of the surface 101a of the tapping plate 101, and the like. The sensor that detects sound may be a so-called pickup or the like. The pickup may be, for example, a piezo pickup, a condenser microphone, or the like. The first sensor 102a and the second sensor 102b may be, for example, a sensor that detects the same type of information, or may be a sensor that detects different types of information. The type here is, for example, a type such as a physical quantity such as pressure or vibration detected by a sensor. Further, the first sensor 102a and the second sensor 102b may be sensors having different sensitivities, outputs, and the like. Here, a case where the first sensor 102a and the second sensor 102b are pressure-sensitive sensors for detecting the pressure applied to the surface 101a of the tapping plate 101 will be described as an example. Here, the first sensor 102a and the second sensor 102b are attached to a portion of the inside of the tapping plate 101 near the surface 101a so that the pressure can be detected when the surface 101a of the tapping plate 101 is tapped. There is. However, the first sensor 102a and the second sensor 102b may be attached to the front surface 101a, the back surface 101b, or the like of the tapping plate 101. For example, the first sensor 102a and the second sensor 102b may be a sheet-shaped pressure-sensitive sensor or the like attached to the surface 101a of the tapping plate 101.

The first sensor 102a and the second sensor 102b are arranged in different regions of the tapping plate 101, and detect information about tapping in different regions of the tapping plate 101, respectively. The different regions of the tapping plate 101 are, for example, different regions in the plane direction of the tapping plate 101. Here, the case where the first sensor 102a is arranged in the region of the tapping plate 101 on the neck 202 side of the guitar 20 and the second sensor 102b is arranged in the region on the bridge 205 side of the guitar 20. Will be explained. However, the area where the first sensor 102a and the second sensor 102b are arranged is not limited to this, and for example, the first sensor 102a and the second sensor 102b are the lengths of the guitar 20. The positions in the directions may be the same, but the distances from the strings 204 of the guitar 20 may be different. If the first sensor 102a and the second sensor 102b can detect information about tapping in different regions of the tapping plate 101, for example, they are at the same position in the plane direction of the tapping plate 101 and are deep. They may be arranged at different positions in the vertical direction. Further, the first sensor 102a and the second sensor 102b do not have to detect information about tapping in different regions of the tapping plate 101, respectively. For example, the first sensor 102a and the second sensor 102b may be a combination of sensors that acquire different types of information regarding tapping on the tapping plate 101. For example, the first sensor 102a may be a vibration sensor that detects vibration due to tapping, and the second sensor 102b may be a sensor that detects sound generated by tapping.

Although the case where the first sensor 102a and the second sensor 102b are provided has been described here, the number of sensors may be one or more. However, when detecting information about tapping in different regions of the tapping plate 101, the number of sensors is preferably two or more.

The output unit 103 determines a sound according to the information detected by the first sensor 102a and the second sensor 102b, and outputs the determined sound. The determination of the sound here may be, for example, determination of the tone color of the sound, determination of the strength of the sound, determination of the pitch of the sound, and determination of the pitch of the sound. The sounding time may be determined, or a combination of two or more of these may be used. The sound intensity may or may not include the loudness, volume, and the like of the sound. The determination of the tone color of the sound may be the determination of the type of sound, and is to determine one or more sounds to be output from the sounds created in advance or the sounds prepared in advance by sampling or the like. You may. Determining the sound may be to acquire a sound signal or to acquire sound information. The acquisition here may be, for example, acquisition by creation or acquisition by reading from a storage unit or the like (not shown). The tone of the sound determined by the output unit 103 is the same as the sound of hitting an object, such as the sound of hitting the sound box of a guitar or the sound of hitting a percussion instrument such as a drum or a cymbal. It is preferable to have.

The output unit 103 individually determines the sound corresponding to the information detected by the first sensor 102a and the sound corresponding to the information detected by the second sensor 102b, and outputs the determined sound for each. .. For example, when the value indicated by the information detected by the first sensor 102a is a value indicating the strength of hitting the tapping plate 101, the output unit 103 indicates that the value indicating the detected information is strongly tapped. A sound having a tone color preliminarily associated with the first sensor 102a, which is a sound that becomes louder continuously or stepwise as the value becomes, is determined as a sound to be output, and this sound is output. For example, when the first sensor 102a is a pressure-sensitive sensor that detects the magnitude of the pressure on the surface 101a of the tapping plate 101, the output unit 103 has a value indicating the magnitude of the pressure detected by the first sensor 102a. A sound having a strength proportional to the magnitude and having a tone color previously associated with the first sensor 102a is determined to be output and output. Similarly, in the output unit 103, for example, when the value indicated by the information detected by the second sensor 102b is a value indicating the strength of hitting the tapping plate 101, the value indicating the detected information is strongly tapped. A sound having a tone color previously associated with the second sensor 102b, which is a sound that becomes louder continuously or stepwise as the value indicates that the information is obtained, is determined as the sound to be output, and this sound is output. do. Since the configuration and processing for outputting a sound having a strength corresponding to the pressure detected by a sensor such as a pressure sensor are known as technologies for electronic drums and the like, detailed description thereof will be omitted here. Even when the first sensor 102a and the second sensor 102b simultaneously detect information regarding tapping, the output unit 103 responds to the information detected by the first sensor 102a and the second sensor 102b, respectively. The sounds may be determined as described above, and the determined sounds may be output at the same time.

By making the sound color preliminarily associated with the first sensor 102a and the sound color preliminarily associated with the second sensor 102b different tones, the first sensor 102a and the second sensor 102a can be described as described above. When the sensor 102b and the sensor 102b are arranged in different regions and the values related to tapping are acquired for the different regions, the region where the first sensor 102a is arranged is tapped and the second sensor 102b is arranged. It is possible to determine and output a sound having a different tone color depending on whether the area is tapped. For example, the sound preliminarily associated with the first sensor 102a and the sound preliminarily associated with the second sensor 102b are, for example, the sounds of different percussion instruments, for example, the sound of a snare drum and the sound of a bass drum. By setting each of these, when the vicinity of the first sensor 102a of the tapping plate 101 is struck, the sound of the snare drum having a strength corresponding to the struck strength is output, and the second tapping plate 101 is set to the second. When the vicinity of the sensor 102b of the above is hit, it is possible to output the sound of the bass drum having a strength corresponding to the hit strength.

When the information regarding the tapping detected by the first sensor 102a is information indicating that the tapping strength is equal to or less than the threshold value, the output unit 103 may not output the sound corresponding to the first sensor 102a. good. The case where the information indicates that the striking strength is equal to or less than the threshold value means that, for example, when a pressure-sensitive sensor that outputs a numerical value of the detected pressure is used as the first sensor 102a, the first sensor 102a detects it. When the numerical value indicating the pressure to be output is equal to or less than the threshold value. With such a configuration, for example, when the area where the second sensor 102b is arranged is hit, in addition to the sound output according to the value indicated by the information detected by the second sensor 102b, the sound is output. It is possible to prevent the first sensor 102a from detecting vibrations, sounds, and the like generated by tapping, and to prevent the sound corresponding to the detected information from being output from the output unit 103. Similarly, when the value indicated by the information detected by the second sensor 102b is a value indicating that the striking strength is equal to or less than the threshold value, the output unit 103 does not output the sound corresponding to the second sensor 102b. You may do so. When the sensitivity of the first sensor 102a and the second sensor 102b is low, such a threshold value may not be provided.

Further, the output unit 103 may determine the sound using both the information regarding the tapping detected by the first sensor 102a and the information detected by the second sensor 102b, and output the determined sound. For example, when the first sensor 102a and the second sensor 102b simultaneously detect information about tapping, the first sensor 102a and the second sensor 102b are not associated with each other in advance. The sound of the tone color previously associated with the combination of the first sensor 102a and the second sensor 102b may be determined and output as the sound to be output. Further, for example, when the first sensor 102a and the second sensor 102b simultaneously detect information regarding tapping, the values indicated by the information detected by the first sensor 102a and the second sensor 102b are compared. The sound associated with the sensor having the larger value may be determined to be the sound to be output and output.

Further, the output unit 103 analyzes the information regarding the tapping detected by the first sensor 102a and the information detected by the second sensor 102b, and obtains information indicating the tapping position of the tapping plate 101 by the user. Acquired and output the sound of the tone color previously associated with the area including the acquired position among the two or more areas previously associated with the different tones preset in the plane direction of the tapping plate 101. You may decide on the sound to be played. Further, the output unit 103 may acquire information indicating the strength of being struck by analysis and determine a sound having a strength corresponding to this strength to be output. In this way, the output unit 103 may output different outputs depending on the tapped region of the tapping plate 101 according to the information acquired by the first sensor 102a and the second sensor 102b. Since the process of analyzing the information detected by two or more sensors and acquiring the information for specifying the struck position is a known technique, detailed description thereof will be omitted.

In addition, the output unit has the output of the sound determined by using both the information detected by the first sensor 102a and the information detected by the second sensor 102b, and the first one as described above. The sound output according to the information detected by the sensor 102a and the sound output according to the information detected by the second sensor 102b may be combined.

When the first sensor 102a detects information related to tapping, the output unit 103 determines and outputs a sound associated with the first sensor 102a in advance, and outputs the sound to be output, and the second sensor 102b. When the information about the tapping is detected, the sound corresponding to the information detected by the first sensor 102a and the sound corresponding to the information detected by the first sensor 102a are determined by determining and outputting the sound associated with the second sensor 102b in advance. The sound corresponding to the information detected by the second sensor 102b may be individually determined and output. Here, it is a sound associated in advance, or, for example, a sound having a predetermined tone color and intensity. The case where the first sensor 102a detects the information regarding the tapping may be the case where the information indicating that the first sensor 102a has been tapped is acquired, and the first sensor 102a is tapped. It may be the case where the information corresponding to the strength is acquired, or the case where the first sensor 102a acquires the information indicating the tapped strength having a strength equal to or higher than a predetermined threshold value. The same applies to the case where the second sensor 102b wants to detect information regarding tapping.
Further, the output unit 103 is

The sound output by the output unit 103 here may be the output of sound from an audio output device (not shown) such as a speaker or earphone, or may be the output of an electric signal of sound. It may be the output of a signal such as a control signal for outputting the sound determined by the output unit 103 to an external sound source or the like (not shown). The electric signal of sound may be an analog signal or a digital signal. Further, the signal such as a control signal for outputting sound may be a so-called MIDI (Musical Instrument Digital Interface) signal. The sound output may be, for example, wired transmission of a sound signal to an output device, or wireless transmission.

As described above, the output unit 103 is not limited to the one that determines the sound according to the information detected by the first sensor 102a and the second sensor 102b and outputs the determined sound. However, the output unit 103 may output according to the information detected by the first sensor 102a and the second sensor 102b. For example, the output unit 103 outputs the information detected by the first sensor 102a and the second sensor 102b as outputs corresponding to the information detected by the first sensor 102a and the second sensor 102b, respectively. You can do it. If the information is not detected, it is not necessary to output the information. Further, whether or not the output unit 103 has detected the information by the first sensor 102a and the second sensor 102b as the output corresponding to the information detected by the first sensor 102a and the second sensor 102b, respectively. Information indicating that may be output. For example, a device (not shown) that receives these outputs may output a sound corresponding to the received outputs.

Further, the output unit 103 may output, for example, the information detected by the first sensor 102a and the second sensor 102b arranged in different regions. Further, the output unit 103 may output information indicating the sensor that has detected the tapping of the first sensor 102a and the second sensor 102b. For example, a device (not shown) that receives these outputs may output a sound corresponding to the received information and associated with the sensor that outputs the received information. Further, the output unit 103 analyzes the information detected by the first sensor 102a and the information detected by the second sensor 102b, and acquires the information indicating the position of the tapping plate 101 to be tapped by the user. , Information indicating this position may be output.

The output here is a concept including sound output, transmission to an external device, storage in a recording medium, delivery of a processing result to another processing device, another program, and the like.

The output unit 103 may or may not include an output device such as a speaker. The output unit 103 may be realized by the driver software of the output device, the driver software of the output device, the output device, or the like. Further, the process of determining the sound performed by the output unit 103 may be realized by hardware (dedicated circuit), or may be realized by software using MPU, memory, or the like. This software may be recorded on a recording medium such as a ROM (not shown), for example.

The output unit 103 or the like of the performance assisting tool 10 may be housed in, for example, a cavity provided in the tapping plate 101, or may be embedded in the tapping plate 101, such as a housing (not shown). It may be arranged inside and provided outside the tapping plate 101, or attached to the outside of the tapping plate 101. The same applies to the reception unit 105, which will be described later.

Next, a specific operation of the performance assisting tool 10 of the present embodiment will be described in a case where the performance assisting tool 10 and the guitar 20 to which the playing assisting tool 10 is attached are used to perform a performance. Here, for convenience of explanation, the region near the region where the first sensor 102a of the tapping plate 101 is arranged is defined as the region near the region where the first sensor 102a is arranged, and the region near the region where the second sensor 102b is arranged is defined as the region. The second region is 1012. It is assumed that the first region 1011 and the second region 1012 do not overlap in the plane direction. Further, it is assumed that both the first sensor 102a and the second sensor 102b are pressure-sensitive sensors. It is assumed that each pressure sensor outputs a signal whose signal strength increases as the applied pressure increases. Further, it is assumed that the output unit 103 is connected to an amplifier (not shown) having a speaker or the like by a wired connection or the like.

When the user taps the first region 1011 of the tapping plate 101, the first sensor 102a detects the tapped pressure and outputs a signal of the strength corresponding to the pressure to the output unit 103. When the output unit 103 receives this signal, it is a sound having a first tone color previously associated with the first sensor 102a, and has a strength corresponding to the strength of the signal output by the first sensor 102a. The sound is determined to be the sound to be output, and the analog signal of the determined sound is transmitted to the above-mentioned amplifier. For example, when the strength of hitting the first region 1011 is high, the output unit 103 is determined as a sound to be output because the signal strength of the signal output by the first sensor 102a is high, and the tapping plate 101 is determined. When the strength of hitting is weak, the signal strength of the signal output by the second sensor 102b is high, so that the weak sound is determined as the output sound. The amplifier emits a sound corresponding to the received analog signal from the speaker. For example, it is assumed that the first tone is a tone similar to the sound obtained when the resonance body of the guitar is struck on the wrist side of the hand.

Further, when the user hits the second region 1012 of the tapping plate 101, the second sensor 102b detects the tapped pressure and outputs a signal of the strength corresponding to the pressure to the output unit 103. .. When the output unit 103 receives this signal, it obtains a second sound color different from the first sound color previously associated with the second sensor 102b, as in the case of receiving the output of the first sensor 102a. A sound having a strength corresponding to the strength of the signal output by the second sensor 102b is determined as the sound to be output, and an analog signal of the determined sound is transmitted to the above-mentioned amplifier. The amplifier emits a sound corresponding to the received analog signal from the speaker. For example, it is assumed that the second tone is a tone similar to the sound obtained when the resonance body of a guitar is hit with a plurality of fingers of a hand.

Further, when both the first region 1011 and the second region 1012 are hit at the same time, the pressure of the first sensor 102a hitting the first region 1011 and the second sensor 102b are the second. The pressure hit by the second region 1012 is detected, and a signal corresponding to the pressure is output to the output unit 103. When the output unit 103 receives these signals, it is a sound having the first tone color as a sound corresponding to the signal output from the first sensor 102a, and corresponds to the signal output by the first sensor 102a. Determines the sound of high intensity as the sound to be output. Further, as a sound corresponding to the signal output from the second sensor 102b, a sound having a second tone and having an intensity corresponding to the signal output by the second sensor 102b is output as a sound. decide. Then, the output unit 103 simultaneously transmits the analog signals of the two determined sounds to the amplifier. For example, the output unit 103 transmits a sound signal obtained by mixing two sounds to an amplifier. The amplifier uses the signal transmitted from the output unit 103 to produce two sounds.

When the user plays, for example, the string 204 of the guitar 20, the sound is output from the guitar 20.

Since the tapping plate 101 is attached near the front side of the position where the user plays the guitar 20, the string 204 of the guitar 20 is played while the tapping plate 101 is tapped, or the string 204 is tapped at the same time as the tapping plate 101 is tapped. It is possible to play and hit. This makes it possible to perform a performance by combining the guitar 20 and the performance assisting tool 10. In particular, by making the first tone and the second tone the sound of hitting different positions of the sound box of the guitar, the sound of hitting the sound box with different tapping methods, etc. as described above, the sound box can be made. Using the non-existent guitar 20, it is possible to perform a performance in which the sound of hitting the sound box and the sound of the guitar are combined.

As described above, according to the performance assisting tool of the present embodiment, by attaching to a guitar having no resonance cylinder, it is possible to play a string while striking.

In addition, according to a guitar that does not have a sound box to which this performance aid is attached, it is possible to play a string while producing a tapped sound.

(Modification example)
As in the performance assisting tool 10a as shown in FIG. 2B, the performance assisting tool 10 described in the above embodiment is further provided with the reception unit 105, and the information received by the reception unit 105 is input. It may be used to determine the sound output by the output unit 103. Hereinafter, such a modification will be described.

The reception unit 105 receives information about the string 204 of the guitar 20. The information about the string 204 of the guitar 20 is the signal of the sound emitted from the guitar 20 etc. when the string 204 of the guitar 20 is played or the string 204 is hit, the information of the vibration of the string 204, and the information of the string 204. It may be information on the vibration of the body 203 of the guitar 20 caused by the vibration. The information about the string 204 of the guitar 20 is the sound generated from the guitar 20, the string 204, etc. by the user's action on the string 204 (for example, the action of playing the string 204, the action of hitting or tapping the string 204, etc.). It may be information indicating the strength of. For example, when the guitar 20 has a pickup (not shown) or the like, the sound signal when the string 204 of the guitar 20 is played is a signal output from an output terminal (not shown) of the sound signal of the string 204 acquired by this pickup. The signal of the sound of the string 204 acquired by the pickup may be amplified by an amplifier (not shown) included in the guitar 20 and output from an output terminal (not shown). A guitar 20 that does not have a resonance body often has a pickup, an amplifier, an output terminal, or the like in order to output the sound of the guitar 20, so these may be used. The pickups here are magnetic pickups, piezo pickups, condenser microphones, and the like. Further, the performance assisting tool 10a has a microphone (not shown) for detecting the sound of the string 204 of the guitar 20 and a sensor (not shown) for detecting the vibration of the body 203 generated by playing the string 204. In addition, the reception unit 105 may accept the information acquired by the microphone or the sensor. The sensor for detecting vibration is preferably provided at a position in contact with the body 203 of the guitar 20, for example.

The reception here is, for example, reception of an input signal transmitted from another device such as a guitar 20 or a sensor (not shown). The reception unit 105 is realized by, for example, an input device or the like.

The output unit 303 determines and determines a sound corresponding to the information detected by the first sensor 102a and the second sensor 102b and the information regarding the string 204 received by the reception unit 105 in the output unit 103 described above. It is designed to output sound. For example, when the information about the string 204 received by the reception unit 105 is information indicated by a numerical value or the like, the output unit 303 is an average value of the information about the string 204 received by the reception unit 105 within a predetermined period. Etc., and the information regarding the tapping detected by the first sensor 102a and the second sensor 102b received within this period may be used to determine the sound.

For example, the output unit 303 determines the sound to be output according to the information regarding the tapping detected by the first sensor 102a and the second sensor 102b, and the reception unit 105 receives the sound, similarly to the output unit 103 described above. The determined sound intensity may be changed according to the information regarding the string 204. Changing the sound intensity may be considered as a correction of the sound intensity. For example, when the information about the string 204 received by the reception unit 105 is the information indicating the sound intensity generated by the user's action on the string 204, the output unit 303 is the first sensor as described above. The tone color and intensity of the sound to be output are determined according to the information detected by the 102a and the second sensor 102b, and the sound intensity indicated by the information received by the reception unit 105 becomes stronger, continuously or stepwise. , The determined sound intensity may be changed (for example, amplified) to be stronger. Increasing the sound intensity indicated by the information received by the reception unit 105 may mean, for example, increasing the loudness of the sound indicated by the sound signal of the guitar 20 received by the reception unit 105. The magnitude of the signal indicating vibration of the string 204 or the guitar 20 received by the reception unit 105 may be increased.

Further, the output unit 303, for example, similarly to the output unit 103 described above, is the first sensor 102a and the second sensor 102b according to the information detected by the first sensor 102a and the second sensor 102b, respectively. The strength of the sound to be output for each is determined, and the tone of the sound to be output from the first sensor 102a and the sound to be output from the second sensor 102b are determined according to the information regarding the string 204 received by the reception unit 105. You may decide the tone and the tone respectively. For example, the output unit 303 analyzes the information about the string 204 received by the reception unit 105, acquires tempo information which is information indicating the characteristics of the music being played, etc., and obtains tempo information according to the acquired tempo. The timbre of the sound output for each of the first sensor 102a and the second sensor 102b may be determined. For example, when the acquired tempo is equal to or less than the threshold value, the tone of the sound output from the first sensor 102a is determined to be the tone of the conga, and the tone of the sound output to the second sensor 102b is determined to be the tone of the tambalin. If the threshold is exceeded, the tone of the sound output from the first sensor 102a may be determined to be the tone of the snare drum, and the tone of the sound output to the second sensor 102b may be determined to be the tone of the high hat. Information for specifying which tone color is to be output at what tempo may be stored in advance in, for example, a storage unit (not shown). This information is, for example, two or more pieces of information having information indicating different tempo ranges and output sound timbres associated with each range. Although the case where the tempo information is used has been described here, information indicating the characteristics of the music other than the tempo may be used. For example, the output unit 303 analyzes the information about the string 204 received by the reception unit 105, acquires information indicating the characteristics of the music other than the tempo (for example, information such as the timbre), and obtains the information indicating the acquired characteristics. It may be used to determine the tone color of the sound to be output as described above. Since the process of acquiring information such as music tone from music information is a known technique, the description thereof is omitted here.

The process of the output unit 303 determining the sound according to the information detected by the first sensor 102a and the second sensor 102b and the information about the string 204 received by the reception unit 105 is the above-mentioned process. Not limited.

Since the points other than the above of the output unit 303 are the same as those of the output unit 103 described above, the description thereof will be omitted here.

When the information received by the reception unit 105 is a sound signal acquired by a pickup or the like (not shown) of the guitar 20, the output unit 303 has the information of this sound received by the reception unit 105 and the first sensor 102a. And the sound signal obtained by mixing the sound signal acquired according to the information detected by the second sensor 102b may be output.

Next, a specific operation of the performance assisting tool 10a of this modification will be described in a case where the performance assisting tool 10a and the guitar 20 to which the playing assisting tool 10a is attached are used to perform a performance. Here, a case where the reception unit 105 is attached to the body 203 of the guitar 20 and connected to a vibration sensor (not shown) for detecting the vibration of the body 203 will be described. This vibration sensor may be considered as a part of the reception unit 105, or may be considered as a part of the performance assisting tool 10a.

When the user plays the string 204 of the guitar 20, the vibration sensor (not shown above) sequentially detects the vibration of the body 203 of the guitar 20, and sequentially outputs a signal indicating the detected vibration to the reception unit 105. do.

When the user taps the first region 1011 of the tapping plate 101, the first sensor 102a detects the tapped pressure and outputs a signal corresponding to the pressure to the output unit 103. Upon receiving this signal, the output unit 103 determines the intensity of the output sound to be the intensity according to the intensity of the signal output by the first sensor 102a. Further, the output unit 103 determines whether or not the signal strength of the signal received by the reception unit 105 is equal to or higher than the threshold value at the same time as the timing of receiving the signal from the first sensor 102a, and if it is equal to or higher than the threshold value. Of the two different tones associated with the first sensor 102a, the tones associated with the signal strength equal to or higher than the threshold value are determined to be the tones of the sound to be output. If it is less than the threshold value, the tone color associated with the signal strength less than the threshold value among the two different tones associated with the first sensor 102a is determined as the tone color of the output sound. Then, the output unit 103 transmits a sound having the tone color and intensity determined as described above to the amplifier, and pronounces the sound received by the amplifier from the speaker. As a result, it is possible to output a sound corresponding to the vibration of the guitar 20 currently being played.

The case where the user hits the second region 1012 of the tapping plate 101 is different from the case where the user hits the first region 1011 except that the second sensor 102b detects the hit pressure. The same is true. In this case, the two different tones associated with the second sensor 102b are preferably different from the two different tones associated with the first sensor 102a, but some of them are in agreement. May be.

In such a modification, when the tapping plate 101 is tapped, a sound corresponding to the user's action on the string 204 of the guitar 20 can be output, and the sound matching the performance of the guitar 20 can be output as the performance assisting tool 10a. Can be output from.

In the above-described embodiment and modification, a case where two sensors, that is, a first sensor 102a and a second sensor 102b, are used as sensors for detecting information on tapping has been described. The number of sensors attached to the tapping plate 101 is not limited to two, and may be one or more. For example, the number of sensors may be 3 or more. For example, three or more sensors are arranged in different regions so as to detect information on tapping in different regions of the tapping plate, and the output unit 103 responds to the information detected by each sensor in the same manner as described above. , The sound to be output may be determined individually, and the determined sound may be output. Further, the output unit 103 may determine the sound to be output as described above according to the information detected by the combination of two or more sensors out of the three or more sensors.

When there is only one sensor, the sensors cannot be placed in different regions of the tapping plate 101. Therefore, simply by associating one sensor with one tone, the output unit 103 is positioned at the tapping plate 101. Sounds of different tones cannot be produced depending on the situation, but different tones are associated with the range of different values of the information detected by this sensor, and the tones associated with the range containing the values of the information detected by this sensor are assigned. , The tone color of the sound output by the output unit 103 may be determined. For example, the pressure and vibration values detected by the sensor differ depending on whether the position of the sensor is far from or close to the tapped position of the tapping plate 101. Normally, the pressure and vibration values at a distance will be small. Therefore, by outputting the sound of the tone color associated with the range of the value including the value detected by the sensor, it is possible to output the sound according to the tapping position of the tapping plate 101.

Further, in the above embodiment, the case where the performance assisting tool includes one tapping plate 101 has been described, but the playing assisting tool may include a plurality of tapping plates 101. The plurality of tapping plates 101 are attached to different positions of the guitar 20, for example. The plurality of tapping plates 101 may be attached to different positions sandwiching the string 204 of the guitar 20, for example. For example, as shown in FIG. 3, the two tapping plates 101 may be attached to the front side and the back side of the guitar 20. It is preferable that one or more mounting positions of the plurality of tapping plates 101 are on the front side of the position where the user of the guitar 20 plays the string 204. However, the mounting position of the plurality of tapping plates 101 with respect to the guitar 20 and the positional relationship between the tapping plates 101 are not limited to this. The plurality of tapping plates 101 may be the same or different in size, shape, internal structure (for example, presence / absence of cavity, shape of cavity, etc.), material, and the like. It is preferable that the performance assisting tool has a different sound generated in response to the tapping when two or more of the plurality of tapping plates 101 are tapped. For example, a plurality of tapping plates 101 have one or more of size, shape, internal structure (for example, presence / absence of cavity, shape of cavity, etc.), material, etc. so that the sound generated in response to tapping differs. It is preferable that they are different.

Further, the performance assisting tool has a plurality of tapping plates 101 as described above, and is further provided with a plurality of sensors 102, so that one or two or more of the plurality of tapping plates 101 are each provided with the above-mentioned 1 The above sensors 102 may be arranged so that each sensor 102 acquires information regarding tapping on the tapping plate 101 provided with each sensor 102. For example, one or more sensors 102 may be arranged only on a part (for example, one) of the plurality of tapping plates 101, and one or more sensors 102 may be arranged on all of the plurality of tapping plates 101. May be placed. For example, the first sensor 102a may be arranged on one of the two tapping plates 101, and the second sensor 102b may be arranged on the other. Further, in this case as well, as described above, the plurality of sensors 102 may be arranged in different regions of one tapping plate 101. The number of sensors 101 arranged on the different tapping plates 101 may be the same or different.

Further, the output unit 103 may determine different sounds according to the information regarding the tapping detected by the sensors 102 arranged on the different tapping plates 101, and output the determined sounds. With such a configuration, as described above, when the performance assisting tool hits two or more of the plurality of hitting plates, the sounds generated in response to the hitting are different. May be good. The different sounds are, for example, sounds having different tones and the like as described above. For example, when the first sensor 102a is arranged on one of the two tapping plates 101 and the second sensor 102b is arranged on the other, the output unit 103 relates to the tapping detected by the first sensor 102a. Different sounds may be determined according to the information and the information regarding the tapping detected by the second sensor 102b, and the determined sounds may be output respectively. For example, when the tapping plate 101 on which the first sensor 102a is arranged is tapped, the output unit 103 determines and outputs the sound of the cymbal according to the information regarding the tapping detected by the first sensor 102a. When the tapping plate 101 on which the first sensor 102a is arranged is tapped, the output unit 103 determines and outputs the sound of the drum according to the information regarding the tapping detected by the first sensor 102a. You may do it.
