Description

  The present invention relates to a saddle with a pickup function.

  When the performance sound of a stringed instrument such as an acoustic guitar is amplified and output electrically, a pickup that detects vibration of the stringed instrument and outputs it as an electric signal is used, and the electric signal from this pickup is amplified by an amplifier. Sound is output electrically.

  As the pickup, a pickup mounted on the body of a stringed instrument and including a piezoelectric element is widespread. This piezoelectric element has a structure in which a piezoelectric body (piezoelectric film) is sandwiched between two electrodes, and is configured to generate a voltage between the electrodes by deformation of the piezoelectric body when subjected to pressure due to vibration.

  In order to electrically output a high-quality sound that is closer to the original sound of a stringed instrument using such a pickup, it is preferable to detect string vibration that contains as little noise (vibration other than strings) as possible. From this point of view, a saddle with a pickup function in which a pickup is incorporated in a saddle (string support) has been devised to facilitate transmission of string vibration to the pickup, and in order to improve detection of string vibration, a saddle has been devised. A saddle with a pickup function (see Japanese Patent Application Laid-Open No. 59-191099) has been developed in which a guide groove corresponding to each string is formed.

  However, the conventional saddle has a structure in which the vibration of the body is inevitably detected simultaneously with the vibration of the string because the pickup is in contact with a part of the body (bridge). For this reason, a signal in which the body vibration is mixed with the string vibration is output, and it is not sufficiently achieved to output the string vibration with less noise as an electric signal.

JP 59-191099 A

  The present invention has been made based on the above-described circumstances, and an object of the present invention is to provide a saddle with a pickup function that can output string vibration as an electric signal while suppressing mixing of body vibration. .

The invention made to solve the above problems is
A saddle with a pickup function that outputs the vibration of a stringed instrument as an electrical signal,
A saddle body having a plurality of string contact positions on the upper surface side;
A sensor having a piezoelectric element disposed below a plurality of string contact positions of the saddle body;
And a plurality of reinforcing portions disposed on the upper surface side or the lower surface side of the piezoelectric element of the sensor at positions facing the plurality of string contact positions.

  In the saddle with a pickup function, a plurality of reinforcing portions that oppose the string contact position are provided on the upper surface side or the lower surface side of the piezoelectric element. The difficulty of deformation with respect to the bending stress in the tangential direction can be increased. As a result, it is possible to suppress the deflection caused by the body vibration at a position opposite to a plurality of string contact positions in the piezoelectric element and detect the transmission intensity of the string vibration relatively larger than the transmission intensity of the body vibration. it can. Therefore, the saddle with a pickup function can output an electric signal of string vibration with a low mixing rate of body vibration.

  The sensor may further include a substrate laminated on the upper surface or the lower surface of the piezoelectric element. By stacking the piezoelectric elements on the substrate in this way, the rigidity of the piezoelectric elements can be increased, and therefore, detection of trunk vibration can be more effectively suppressed in the saddle with a pickup function. In addition, since the sensor has a substrate, it is possible to easily and surely implement a plurality of piezoelectric elements and adjustment of the arrangement position as described later.

  The sensor may include a plurality of piezoelectric elements disposed at positions facing the plurality of string contact positions. When the sensor has such a plurality of piezoelectric elements, it is possible to further enhance the effect of suppressing the detection of body vibration and to reliably detect the vibration of each string.

  When the sensor includes a substrate, the piezoelectric element may be stacked on the upper surface of the substrate, and the plurality of reinforcing portions may be attached to the lower surface of the substrate. By laminating the piezoelectric elements on the upper surface of the substrate in this manner, it is possible to detect the vibration of the string more easily and reliably, and at the same time, it is possible to suppress the detection of the trunk vibration transmitted from the lower surface side. Further, by attaching the reinforcing portion to the lower surface of the substrate, it is possible to further increase the rigidity of the piezoelectric element at the position facing each string. As a result, in the saddle with a pickup function, detection of body vibration can be more effectively suppressed.

  The plurality of reinforcing portions may be formed integrally with the saddle body. Thus, by forming the reinforcing portion integrally with the saddle body, the manufacturing cost of the saddle with a pickup function can be reduced.

  In addition, the vertical relationship regarding the “upper surface” and the “lower surface” is such that the outer direction of the body of the stringed instrument is up and the opposite direction is down.

  As described above, the saddle with a pickup function according to the present invention can output string vibration as an electric signal while suppressing mixing of body vibration. Therefore, the performance sound of the stringed instrument can be electrically output with high quality and can be suitably used for an acoustic guitar or the like.

  Hereinafter, embodiments of a saddle with a pickup function of the present invention will be described in detail with reference to the drawings as appropriate.

<First embodiment>
The saddle 1 with a pickup function shown in FIG. 1 is generally provided on the surface side of the body of a stringed musical instrument via a piece and supports a plurality of strings. The saddle 1 with a pickup function is a long and narrow plate-like body, and the longitudinal direction thereof is disposed substantially parallel to the surface of the body portion, and the plate surface is disposed substantially perpendicular to the surface of the body portion. The saddle 1 with a pickup function includes a saddle body 2, a sensor 3 disposed in the saddle body 2, an upper reinforcing portion 4, and a lower reinforcing portion 5. Hereinafter, the structure of the saddle 1 with a pickup function will be specifically described.

  The saddle body 2 has a plurality of string contact positions with which the string X contacts the upper surface. The saddle body 2 includes a substantially rectangular parallelepiped saddle upper portion 2a and a substantially rectangular parallelepiped saddle lower portion 2b located on the lower surface of the saddle upper portion 2a. The saddle body 2 has an internal space portion 6a in which the sensor 3 is housed (between the saddle upper portion 2a and the saddle lower portion 2b), and a lead wire (not shown) connected to the sensor 3 is provided in the internal space. A lead wire insertion hole 6b is provided through the portion 6a to the lower side of the saddle lower portion 2b. In the internal space 6 a, the sensor 3 is disposed via the upper reinforcing portion 4 and the lower reinforcing portion 5.

  The size of the saddle upper portion 2a is not particularly limited as long as it can support the string of the stringed musical instrument to which the saddle 1 with the pickup function is mounted. For example, when it is mounted on an acoustic guitar having six strings, the length (string The arrangement direction can be 70 mm or more and 90 mm or less, the width (direction parallel to the string) can be 2 mm or more and 4 mm or less, and the height (string contact direction) can be 3 mm or more and 6 mm or less. Further, as the size of the saddle lower portion 2b, the length and width can be the same as those of the saddle upper portion 2a, and the height can be 3 mm or more and 6 mm or less.

  As the material of the saddle upper portion 2a and the saddle lower portion 2b, known materials can be used as the saddle material. For example, ivory, cow bone, synthetic resin, etc. can be used. Resins are particularly preferred. It is also possible to use different materials for the saddle upper portion 2a and the saddle lower portion 2b.

  The distance from the string contact surface of the saddle upper portion 2a to the internal space 6a can be, for example, 3 mm to 6 mm. The size of the internal space 6a is, for example, 65 mm to 85 mm in length, The width can be 2 mm or more and 4 mm or less, and the height can be 0.5 mm or more and 3 mm or less. Furthermore, the diameter of the lead wire insertion hole 6b can be 2 mm or more and 5 mm or less.

  The sensor 3 is a flat sensor body having a substrate 3a and a plurality of piezoelectric elements 3b. The plurality of piezoelectric elements 3b are arranged in pairs on the upper surface of the substrate 3a so as to oppose the plurality of string abutting positions of the saddle body 2, that is, just below each string. The sensor 3 has an electrode terminal (not shown) to which a lead wire is connected. The vibration of the string X is transmitted as pressure to each piezoelectric element 3b of the sensor 3 via the saddle upper portion 2a and the upper reinforcing portion 4, and is converted into an electric signal and output from the lead wire to the outside.

  The size of the substrate 3a is not particularly limited. For example, the thickness may be 50 μm to 3 mm, the width may be 0.5 mm to 3 mm, and the length may be 30 mm to 70 mm. However, the thickness is preferably set to 50 μm or more and 0.5 mm or less so that the portion of the substrate 3a that is not sandwiched between the reinforcing portions is easily bent. By setting the thickness of the substrate 3a within the above range, the portion that is not sandwiched between the reinforcing portions is easily bent due to the barrel vibration, so that it is possible to suppress the occurrence of bending due to the barrel vibration in the portion sandwiched between the reinforcing portions.

  The material of the substrate 3a is not particularly limited, and for example, synthetic resin, rubber, metal, metal compound, ceramics, or the like can be used. Specific examples of the material of the substrate 3a include silicon, sapphire, alumina, zirconia, magnesia, silicon carbide, glass, silicon nitride, stainless steel, titanium carbide, titanium nitride, etc. Among these, zirconia is preferable, Stabilized zirconia is particularly preferred. Thus, by using a material having high toughness, the substrate 3a itself can be made thin, and as a result, even a material having a high Young's modulus can be kept low in rigidity. And the part which is not pinched | interposed into the reinforcement part of the board | substrate 3a can be easily bent by trunk vibration, and it can suppress that the bending | flexion by trunk vibration generate | occur | produces in the part pinched | interposed into a reinforcement part.

  The structure of the piezoelectric element 3b is not particularly limited. For example, a structure in which a piezoelectric film is sandwiched between an upper electrode and a lower electrode can be used. The size of the piezoelectric element 3b is not particularly limited as long as the vibration of the string can be converted into a sufficiently large voltage. For example, the thickness is 10 μm or more and 100 μm or less, and the length in the width direction of the substrate 3a is 0.5 mm. The length in the longitudinal direction of the base material 3a can be 0.5 mm or more and 10 mm or less.

  The material of the piezoelectric film used for the piezoelectric element 3b is not particularly limited as long as it generates a voltage due to the piezoelectric effect, and examples thereof include various oxides, nitrides, and polymers. Specific examples of the material of the piezoelectric film include single crystals such as lead zirconate titanate (PZT), quartz, lithium niobate, lithium tantalate, lithium tetraborate, potassium niobate, and langasite crystals, zinc oxide, Examples thereof include oriented crystals such as aluminum nitride, polyvinylidene fluoride, etc. Among them, lead zirconate titanate having high piezoelectricity is particularly preferable.

  The material of the electrode used for the piezoelectric element 3b is not particularly limited as long as it has electrical conductivity. Examples thereof include platinum, aluminum, nickel, iron, gold, silver, copper, palladium, chromium, and alloys thereof. Can do. Among these, platinum or gold is preferable from the viewpoint of electrical conductivity or chemical stability, and platinum is more preferable.

  A method for laminating the piezoelectric element 3b on the substrate 3a is not particularly limited, and for example, a screen printing method, a sputtering method, a vacuum deposition method, a plating method, a dipping method, or the like can be used.

  The connection method of the lead wire to the electrode terminal of the sensor 3 is not particularly limited, and a known method can be used. Specifically, for example, soldering, connection with a crimping fitting, adhesion with a conductive adhesive, wire bonding, and the like can be given. It is possible to separate and output the vibration of each string by connecting a lead wire to each piezoelectric element 3b. However, according to the saddle 1 with a pickup function of the present invention, detection of body vibration can be suppressed, so that a sufficiently high-quality sound can be output without such a configuration.

  The upper reinforcing portion 4 is a flat plate having a rectangular shape in plan view, and is located at a position opposite to the plurality of string contact positions of the saddle body 2 between the saddle upper portion 2a and each piezoelectric element 3b of the sensor 3. It is arranged. The upper reinforcing portion 4 is integrally formed with the saddle upper portion 2a and joined to each piezoelectric element 3b. The sensor 3 may be turned upside down to join the saddle upper portion 2a and the substrate 3a.

  The size of the upper reinforcing portion 4 is preferably substantially the same as that of the piezoelectric element 3b in a plan view. For example, the thickness is 20 μm or more and 1 mm or less, and the length in the width direction of the substrate 3a is 0.5 mm or more and 2 mm or less. The length in the longitudinal direction of the substrate 3a can be set to 0.5 mm or more and 10 mm or less. The upper reinforcing portion 4 may have the same size and shape as the abutting piezoelectric element 3b, or either one may be larger than the other, or may have different shapes.

  As the material of the upper reinforcing portion 4, the same material as that of the saddle upper portion 2a is preferable. By making the material of the saddle upper part 2a and the upper reinforcing part 4 the same, it becomes easy to manufacture and it is possible to prevent a reduction in transmission loss of string vibration.

  The lower reinforcing portion 5 is a flat plate having a rectangular shape in plan view, and is opposed to each upper reinforcing portion 4 with the sensor 3 interposed between the substrate 3a of the sensor 3 and the saddle lower portion 2b (the saddle body 2). It is arranged so as to face a plurality of string contact positions. The lower reinforcing portion 5 is attached to the lower surface of the substrate 3a.

  The size of the lower reinforcing portion 5 is preferably substantially the same as that of the piezoelectric element 3b in a plan view. For example, the thickness is 20 μm or more and 1 mm or less, and the length in the width direction of the substrate 3a is 0.5 mm or more and 2 mm or less. The length in the longitudinal direction of the substrate 3a can be set to 0.5 mm or more and 10 mm or less. The upper reinforcing portion 5 may have the same size and shape as the upper reinforcing portion 4 or the piezoelectric element 3b, may have a different size, or may have a different shape.

  The material of the lower reinforcing portion 5 is not particularly limited, but it is preferable to use a material different from that of the saddle lower portion 2b in order to suppress transmission of body vibration to the sensor 3. In particular, a material having a high Young's modulus is preferable from the viewpoint of increasing the rigidity of the reinforced portion by the lower reinforcing portion 5, and for example, a metal material such as brass, iron, or stainless steel, or a ceramic material such as alumina or aluminum nitride is used. Can do. Moreover, you may further arrange | position the member which consists of a soft material which absorbs a vibration below the lower reinforcement part 5 from a viewpoint of suppressing vibration transmission of a trunk | drum more. Examples of the soft material that absorbs the vibration include elastomers and polyethylene.

  The method of attaching the lower reinforcing portion 5 to the lower surface of the substrate 3a is not particularly limited, and for example, a method of bonding the upper surface of the lower reinforcing portion 5 to the lower surface of the substrate 3a with an adhesive can be used.

  The method for fixing the sensor 3 to the saddle body 2 is not particularly limited, and the piezoelectric element 3b may be joined to the upper reinforcing portion 4 and the lower reinforcing portion 5 may be joined to the saddle lower portion 2b. It may be only sandwiched between the upper part 2a and the saddle lower part 2b. However, it is preferable to adhere the surface of each piezoelectric element 3b to each upper reinforcing portion 4 so that the vibration of the string can be transmitted more reliably.

  The saddle upper portion 2a and the saddle lower portion 2b are fixed by means such as pinning, screwing, or bonding with an adhesive.

  In the saddle 1 with a pickup function, a plurality of piezoelectric elements 3b are disposed below a plurality of string contact positions of the saddle body 2, and an upper reinforcing portion 4 is disposed on the upper surface of each piezoelectric element 3b. A lower reinforcing portion 5 is attached (fixed) at a position facing the upper reinforcing portion 4 across the substrate 3a and the piezoelectric element 3b. Thereby, in the board | substrate 3a, the part in which the piezoelectric element 3b is laminated | stacked has high rigidity with respect to the part in which the piezoelectric element 3b is not laminated | stacked. Therefore, bending due to body vibration is likely to occur in a portion where the piezoelectric element 3b is not stacked, and is difficult to occur in a portion where the piezoelectric element 3b is stacked. That is, the saddle body 2 has a structure in which pressure due to body vibration is not easily applied to the piezoelectric element 3b. As a result, the saddle 1 with a pickup function can output an electric signal of string vibration with a low mixing rate of body vibration.

  Further, in the saddle 1 with a pickup function, the piezoelectric element 3b is laminated on the upper surface of the substrate 3a, and the lower reinforcing portion 5 is attached to the lower surface side of the substrate 3a, so that the body vibration is transmitted to the piezoelectric element 3b. It is suppressed. Furthermore, since the upper reinforcing portion 4 integrally formed with the saddle upper portion 2a is evenly arranged on the upper surface side of the piezoelectric element 3b, the vibration of each string is easily transmitted to the piezoelectric element 3b. As a result, the saddle 1 with a pickup function has a high trunk vibration transmission preventing effect.

<Second embodiment>
The saddle 11 with a pickup function in FIG. 2 is the same as the saddle 1 with a pickup function in FIG. 1, and includes a saddle body 12, a sensor 3 disposed in the saddle body 12, an upper reinforcing portion 4, and a lower reinforcement. Part 5. The piezoelectric sensor 3 and the upper reinforcing portion 4 and the lower reinforcing portion 5 are the same as those of the saddle 1 with a pickup function, and thus the same numbers are given and the description thereof is omitted.

  The saddle body 12 has a string contact position where the string X contacts the upper surface, and an internal space portion 16a. The internal space 16a houses the sensor 3 and is filled with a synthetic resin. The saddle body 12 has a lead wire insertion hole 16b through which a lead wire (not shown) connected to the sensor 3 is inserted from the internal space portion 16a to the lower side of the saddle body 12.

  The size of the saddle body 12 is not particularly limited as long as it can support the string of the stringed instrument to which the saddle 11 with the pickup function is attached. For example, when attached to an acoustic guitar having 6 strings, the length is 70 mm or more. The width can be 90 mm or less, the width can be 2 mm or more and 4 mm or less, and the height can be 5 mm or more and 15 mm or less.

  Further, the distance from the string contact surface of the saddle body 12 to the internal space portion 16a and the size of the internal space portion 16a can be the same as those of the saddle 1 with a pickup function in FIG.

  As the material of the saddle body 12, known materials can be used as the saddle material. For example, ivory, cow bone, artificial ivory, synthetic resin, etc. can be used. From the viewpoint of rigidity and cost, urea resin is used. Is particularly preferred.

  In the internal space portion 16a, each piezoelectric element 3b is joined to each upper reinforcing portion 4. The method of joining the piezoelectric element 3b and the upper reinforcing portion 4 is not particularly limited, and for example, a method of bonding with an adhesive can be used.

  The internal space 16a is filled with synthetic resin, and the sensor 3 is fixed. Although it does not specifically limit as a synthetic resin with which the internal space part 16a is filled, In order to make the board | substrate 3a easy to bend, it is preferable to use an elastomer etc., for example. It is also possible not to fill the internal space 16a with synthetic resin. In that case, the board 3a constituting the sensor 3 can be made particularly easy to bend.

  Since the saddle 11 with a pickup function has the same structural features as the saddle 1 with a pickup function in FIG. 1, it is difficult for vibration of the trunk to be transmitted to the piezoelectric element 3 b and at the same time, vibration of each string is easily transmitted. The transmission intensity of the string vibration can be made relatively larger than the transmission intensity of the trunk vibration. As a result, the saddle 11 with a pickup function can output an electric signal of string vibration with a low mixing rate of body vibration.

<Third embodiment>
The saddle 21 with a pickup function shown in FIG. 3 includes a saddle body 2, a sensor 23 disposed in the saddle body 2, and an upper reinforcing portion 4 and a lower reinforcing portion 5. Since the saddle body 2, the upper reinforcing portion 4 and the lower reinforcing portion 5, the internal space portion 6a and the lead wire insertion hole 6b in the saddle main body 2 are the same as the saddle 1 with a pickup function in FIG. The same numbers are assigned and explanations are omitted.

  The sensor 23 is a flat sensor body having a substrate 23a and a single piezoelectric element 23b. The piezoelectric element 23b is laminated in a band shape on the upper surface of the substrate 23a. Each piezoelectric element 23 b is joined to the upper reinforcing portion 4. The vibration of the string X is transmitted as pressure through the saddle upper portion 2a and the upper reinforcing portion 4 to a portion in contact with the upper reinforcing portion 4 of the piezoelectric element 23a of the sensor 23, and is converted into an electric signal to be transmitted from the lead wire to the outside. Is output.

  The substrate 23a can be the same as the substrate 3a of the saddle 1 with a pickup function in FIG.

  The structure of the piezoelectric element 23b is not particularly limited. For example, a structure in which a piezoelectric film is sandwiched between an upper electrode and a lower electrode can be used. The size of the piezoelectric element 23b is not particularly limited as long as the vibration of each string can be converted into a sufficiently large voltage. For example, the thickness is 10 μm or more and 100 μm or less, and the length of the base material 23a in the width direction is 0.1. The length in the longitudinal direction of the base material 23a can be 30 mm or more and 70 mm or less.

  The material of the piezoelectric film and electrodes forming the piezoelectric element 23b and the method of stacking the piezoelectric element 23b on the substrate 23a can be the same as those of the saddle 1 with the pickup function in FIG.

  The method of joining the piezoelectric element 23b to the upper reinforcing portion 4 is not particularly limited, and for example, a method of bonding the piezoelectric element 23b to the lower surface of each upper reinforcing portion 4 with an adhesive can be used.

  The saddle 21 with a pickup function makes it difficult for the upper reinforcing portion 4 and the lower reinforcing portion 5 to transmit the vibration of the trunk to the piezoelectric element 23b, and at the same time, the vibration of each string is easily transmitted. It can be relatively increased with respect to the transmission intensity of the trunk vibration. As a result, the saddle 21 with a pickup function can output an electric signal of string vibration with a low mixing rate of body vibration.

  Further, in the saddle 21 with a pickup function, since the sensor 23 has a single piezoelectric element 23b, the sensor 23 can be manufactured and joined to the saddle upper portion 2a relatively easily. In the present embodiment, in the single piezoelectric element 23b, the sensitivity in the region where the string and the pair are not disposed (the region where the reinforcing member is not disposed) can be reduced to make it difficult to detect the vibration of the trunk. As a method for reducing the sensitivity, for example, when forming the piezoelectric element 23b, a method of narrowing or reducing the thickness of a portion that is not disposed with the string is not disposed, or the piezoelectric element 23b is not disposed with the string. A method in which no electrode is laminated on the portion is conceivable.

<Other embodiments>
The saddle with a pickup function of the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the upper reinforcing portion is integrally formed with the saddle upper portion, but each upper reinforcing portion may be formed as a separate member and attached to the saddle upper portion.

  Further, a saddle with a pickup function that does not include the upper reinforcing portion as shown in each embodiment and includes only the lower reinforcing portion is within the scope of the present invention. Such a saddle with a pickup function can improve the productivity by omitting the upper reinforcing portion, although the effect of improving the rigidity of the sensor by the upper reinforcing portion and the effect of improving the transmission property of the string vibration cannot be obtained. In the case where the upper reinforcing portion is not provided, it is preferable to join the sensor to the lower surface of the upper portion of the saddle (or the upper surface of the internal space portion) in order to improve the transmission of the string vibration.

  Similarly, a saddle with a pickup function that does not include the lower reinforcing portion and includes only the upper reinforcing portion is also within the intended scope of the present invention. Such a saddle with a pickup function cannot improve the rigidity of the sensor by the lower reinforcing portion, but can improve productivity by omitting the lower reinforcing portion.

  In each of the above embodiments, the piezoelectric element is laminated on the upper surface of the base material. However, the structure of the sensor that can be used in the present invention is not limited to this, and the piezoelectric element may be laminated on the lower surface of the base material. As described above, it is desirable to stack the piezoelectric element on the upper surface of the base material. However, when the productivity of the saddle with a pickup function is excellent, the piezoelectric element can be stacked on the lower surface in accordance with the manufacturing process. is there.

  Further, as a sensor disposed in the saddle body, it is possible to use a sensor body that does not have a substrate and has electrodes printed on both sides of the piezoelectric film by screen printing or the like.

  As described above, the saddle with a pickup function according to the present invention can output string vibration as an electric signal while suppressing mixing of body vibration. Therefore, the performance sound of the stringed instrument can be electrically output with high quality and can be suitably used for a stringed instrument such as an acoustic guitar.
