Microphone Holder

[0001] The present invention relates to a microphone holder.

[0002] 2. Description of the Related Art Conventionally, a mounting device for attaching a microphone to a musical instrument has been known that has a pinch structure provided with a pair of clip members (see, for example, Patent Document 1).

[0003] JP 2016-82421 A

[0004] The mounting device of Patent Document 1 has a pinch structure, which is preferable in that it can be easily attached to and detached from the musical instrument, but there is room for improvement in terms of stability when attached to the musical instrument.

[0005] SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a microphone holder that enables a microphone to be stably attached to a musical instrument.

[0006] One form of the microphone holder of the present invention is a microphone holder comprising: a microphone holding portion that holds a microphone; and an attachment mechanism connected to the microphone holding portion and attached to an instrument, wherein the attachment mechanism comprises a first clamp member; a second clamp member that is rotatable relative to the first clamp member around a rotation axis; and a biasing member that biases the first clamp member and the second clamp member in a direction such that the tip of the first clamp member and the tip of the second clamp member approach each other, wherein the first clamp member has a first elastic portion that abuts against a first surface member that forms a first surface of the main body portion of the instrument when the microphone holder is attached to the instrument, and the second clamp member has a second elastic portion that abuts against a second surface member of the instrument that faces the first surface member when the microphone holder is attached to the instrument, and a third elastic portion that abuts against a third surface member that forms the side of the main body portion.

[0007] Between the second elastic portion and the third elastic portion, a recess may be provided so that when the microphone holder is attached to the instrument and the second elastic portion and the third elastic portion are in contact with the second surface member and the third surface member, respectively, the corner where the second surface member and the third surface member connect or the end of the second surface member do not come into contact.

[0008] The second elastic portion and the third elastic portion may be integrally formed as a single member.

[0009] At least one of the first elastic portion and the second elastic portion may include a protrusion protruding from the tip portion, and the protrusion may have a curved contour portion defined by one radius of curvature or multiple radii of curvature.

[0010] The microphone holding portion has a cup portion into which the shaft portion of the microphone is fitted and a support member connected to the cup portion, and the support member is a member that protrudes from the mounting mechanism, and the cup portion may be provided on the support member in an orientation such that the direction in which the shaft portion is fitted intersects the protruding direction of the support member.

[0011] The support member may extend in a direction coaxial with the rotation axis and be rotatable around the rotation axis so that the orientation of the microphone can be changed.

[0012] Another aspect of the present invention provides a microphone holder including a microphone holding portion for holding a microphone, and an attachment mechanism connected to the microphone holding portion and attached to a musical instrument, the attachment mechanism including a first clamp member, a second clamp member provided rotatably about a rotation axis relative to the first clamp member, and a biasing member for biasing the first clamp member and the second clamp member in a direction in which a tip end of the first clamp member and a tip end of the second clamp member approach each other, and the first clamp member The microphone holder has a first elastic portion that abuts against the surface of a first surface member that forms the first side of the main body of the instrument when the microphone holder is attached to the instrument, and a convex elastic portion that abuts against the end of the first surface member, and the second clamp member has a second elastic portion that abuts against a second surface member of the instrument that faces the first surface member when the microphone holder is attached to the instrument, and the attachment mechanism is configured so that the microphone holder does not abut against a third surface member that forms the side of the main body when the microphone holder is attached to the instrument.

[0013] The second clamp member is provided closer to the rotation axis than the second elastic portion, and further has a thick side portion that protrudes toward the side of the instrument when the microphone holder is attached to the instrument, and the thick side portion may have a protrusion that comes into contact with the side when the main body portion is about to be sandwiched between the convex elastic portion and the second elastic portion, preventing the convex elastic portion and the second elastic portion from moving to a position where the main body portion can be sandwiched between the convex elastic portion and the second elastic portion.

[0014] The microphone holding portion has a cup portion into which the shaft portion of the microphone is fitted and a support member connected to the cup portion, and the support member is a member that protrudes from the mounting mechanism, and the cup portion may be provided on the support member in an orientation such that the direction in which the shaft portion is fitted intersects the protruding direction of the support member.

[0015] The support member may extend in a direction coaxial with the rotation axis and be rotatable around the rotation axis so that the orientation of the microphone can be changed.

[0016] A flat portion may be formed on the outer periphery of the support member on the side opposite to the position where the cup portion is provided.

[0017] The present invention has the effect of providing a microphone holder that allows a microphone to be stably attached to a musical instrument.

[0019] (First embodiment) Fig. 1 is a diagram showing a state in which a microphone is attached to a musical instrument by a microphone holder, Fig. 2 is a perspective view of the microphone holder, and Fig. 3 is a side view of the microphone holder.

[0020] The microphone holder S100 is used to attach the microphone 1 to a musical instrument 5. The musical instrument 5 is, for example, a violin or a viola. In this embodiment, a violin is used as an example of the musical instrument 5. The musical instrument 5 has a body portion 6 and a neck portion 7.

[0021] The main body 6 has a top plate 6a, a back plate 6b, and side plates 6c, and is formed in a box shape. The main body 6 has a generally rectangular cross section. Specifically, the top plate 6a and the back plate 6b are arranged to face each other. The top plate 6a is a member that forms the first surface (surface) of the instrument 5. The side plates 6c extend in a direction intersecting the top plate 6a and the back plate 6b so as to connect the top plate 6a and the back plate 6b. The top plate 6a corresponds to the "first surface member" of the present invention, the back plate 6b corresponds to the "second surface member," and the side plates 6c correspond to the "third surface member."

[0022] The side plate 6c extends in the Z direction (thickness direction of the main body 6) in FIG. 1. The end of the front plate 6a protrudes slightly beyond the side plate 6c in the X direction. As an example, the end of the front plate 6a is formed in an arc shape or a nearly arc shape. Similarly, the end of the back plate 6b protrudes slightly beyond the side plate 6c in the X direction. As an example, the end of the back plate 6b is formed in an arc shape or a nearly arc shape.

[0023] The microphone 1 has a sound collection unit 1a and a shaft unit 1b. The shaft unit 1b is a member that supports the sound collection unit 1a. As an example, the shaft unit 1b is a round bar-shaped member with a circular cross section. The shaft unit 1b is provided so as to be deformable so that the sound collection unit 1a can be oriented in a desired direction.

[0024] [Microphone Holder S100] As shown in Fig. 2(a), the microphone holder S100 includes a microphone holding portion 10 and an attachment mechanism 20. As will be described later, the rotation axis L1 in Fig. 2(b) is the center of rotation when the first clamp member 21 and the second clamp member 25 rotate relative to each other.

[0025] (Microphone holding portion 10) The microphone holding portion 10 is a structure for holding the microphone 1. Specifically, the microphone holding portion 10 has a support member 11 and a cup portion 12, as shown in FIG.

[0026] The support member 11 is a member that protrudes from the mounting mechanism 20. In this example, the support member 11 has a generally cylindrical shape. The support member 11 extends in a direction parallel to the direction in which the rotation axis L1 extends. Specifically, the support member 11 is oriented such that its central axis coincides with the rotation axis L1.

[0027] As shown in Fig. 3, the support member 11 is configured to be rotatable relative to the first clamp member 21 and the second clamp member 25 around a rotation axis L1. This configuration makes it possible to adjust the orientation of the microphone 1. Note that it is not essential to the present invention that the support member 11 be configured to rotate, and the support member 11 may be provided in a manner that does not rotate relative to the mounting mechanism 20. Even with this configuration, as long as the shaft portion 1b of the microphone 1 is sufficiently deformable, the sound collection portion 1a can be oriented in a desired direction, and the sound of the musical instrument 5 can be recorded satisfactorily.

[0028] The cup portion 12 is formed in a shape into which the shaft portion 1b of the microphone 1 is fitted. The cup portion 12 has, for example, a C-shaped cross section. As shown in Fig. 2(b), the cup portion 12 is fixed to the outer periphery of the support member 11. Specifically, the cup portion 12 is provided so that the direction in which the shaft portion 1b is fitted (see arrow A) intersects with the protruding direction of the support member 11 (the same as the extending direction of the rotation axis L1 in Fig. 2).

[0029] A flat portion 11a is formed on the outer periphery of the support member 11 on the side opposite to the position where the cup portion 12 is provided. The flat portion 11a is a surface shaped by cutting away a portion of the outer periphery of a cylinder along a plane. In this example, the flat portion 11a extends in a direction perpendicular to the direction of arrow A (in other words, the normal direction of the surface of the flat portion 11a is parallel to the direction of arrow A, which is the fitting direction of the shaft portion 1b).

[0030] FIG. 4 is a diagram showing how a user fits the shank 1b of the microphone 1 into the cup portion 12. The support member 11 protruding from the attachment mechanism 20 and the cup portion 12 being positioned relative to the support member 11 as described above provide the following advantages. Specifically, as shown in FIG. 4 , a user presses the support member 11 with, for example, their index finger and pushes the shank 1b toward the cup portion 12 with their thumb, causing the shank 1b to fit into the cup portion 12. According to the configuration of this embodiment, the force pushing the shank 1b is less likely to be transmitted to the attachment mechanism 20, and therefore the attachment mechanism 20 is less likely to shift position when fitting the shank 1b. Therefore, even if the shank 1b is fitted into the cup portion 12 while the microphone holder S100 is attached to the musical instrument 5, the possibility of the microphone holder S100 moving and damaging the musical instrument 5 is reduced. Furthermore, when the flat portion 11a is provided, the user can hold the support member 11 securely and push the shaft portion 1b toward the support member 11, thereby reducing the occurrence of installation errors of the microphone 1.

[0031] 1 and 2, the attachment mechanism 20 includes a first clamp member 21, a second clamp member 25, a biasing member 40, and a connecting member 41. The first clamp member 21 and the second clamp member 25 are connected to each other by the connecting member 41 and are configured to rotate relative to each other about a rotation axis L1.

[0032] The biasing member 40 is, for example, a torsion spring. The biasing member 40 applies a biasing force to the first clamp member 21 and the second clamp member 25 so that the microphone holder S100 closes, i.e., so that the tip end of the first clamp member 21 and the tip end of the second clamp member 25 approach each other.

[0033] 2A, the first clamp member 21 has an extension portion 22, a central portion 23, an operating portion 24, and an elastic member 31. The first clamp member 21 is, for example, a resin part in which the extension portion 22, the central portion 23, and the operating portion 24 are integrally formed.

[0034] The central portion 23 is a portion having a through-hole (not shown) through which the connecting member 41 is passed. The extending portion 22 is a portion that extends in a direction away from the central portion 23. As shown in Fig. 2(a) , the tip side of the extending portion 22 extends in the left-right direction that is perpendicular to the extending direction of the extending portion 22 (the front-to-back direction in the figure).

[0035] The operation unit 24 is a part that is operated by a user. The operation unit 24 extends from the central portion 23 to the opposite side to the extension portion 22.

[0036] The elastic member 31 is formed of, for example, elastically deformable silicone rubber or a foam material so as not to damage the musical instrument 5. As shown in FIG. 1 , the elastic member 31 abuts against the surface of the top plate 6a of the musical instrument 5 when the microphone holder S100 is attached to the musical instrument 5. As shown in FIG. 2( a), in this embodiment, the elastic member 31 includes a base portion 31a, a first protrusion 31b-1, and a second protrusion 31b-2. While this embodiment illustrates an elastic member 31 having two protrusions, the elastic member may also have a single protrusion. Because the first protrusion 31b-1 and the second protrusion 31b-2 have the same shape, only the first protrusion 31b-1 will be described below. Hereinafter, the first protrusion 31b-1 will also be referred to simply as the first protrusion 31b. The first protrusion 31b corresponds to the first elastic portion of the present invention.

[0037] Fig. 5 is a diagram showing a state in which the microphone holder S100 is attached to a musical instrument 5. In Fig. 5, the cross-sectional shape of the main body 6 of the musical instrument 5 is schematically depicted as a rectangle. Fig. 5(a) shows a state in which the microphone holder S100 is attached to an instrument with a relatively thick main body, such as a viola, and Fig. 5(b) shows a state in which the microphone holder S100 is attached to an instrument with a relatively thin main body, such as a violin.

[0038] As shown in FIG. 5( a), the first protrusion 31b of the elastic member 31 protrudes from the tip of the extension 22. Specifically, the first protrusion 31b is formed to have a curved contour (e.g., an arc-shaped portion) in a side view. This contour may have a shape defined by one or more radii of curvature. By having the first protrusion 31b have such a shape, the microphone holder S100 can be suitably attached to musical instruments 5 of various thicknesses, as shown in FIGS. 5( a) and 5(b).

[0039] The second clamp member 25 is provided rotatably about a rotation axis L1 relative to the first clamp member 21. As shown in FIG. 2A, the second clamp member 25 has an extension portion 26, a central portion 27, an operating portion 28, and an elastic member 35.

[0040] The central portion 27 has a through-hole (not shown) through which the connecting member 41 is passed. The extending portion 26 extends away from the central portion 27. Specifically, the extending portion 26 includes a straight portion 26-1 and a tip portion 26-2. The straight portion 26-1 is a long, thin, plate-like portion formed in a straight line. The tip portion 26-2 is formed to connect to the straight portion 26-1 and forms a predetermined angle with respect to the straight portion 26-1. The tip portion 26-2 is inclined with respect to the straight portion 26-1, for example, at an angle greater than 100° and less than or equal to 120°. Compared to when the tip portion 26-2 is perpendicular to the straight portion 26-1, forming the tip portion 26-2 at such an angle allows the microphone holder S100 to properly hold musical instruments 5 of various thicknesses.

[0041] The operation section 28 is a section that is operated by the user, and extends from the central section 27 in the opposite direction to the extension section 26 .

[0042] Like the elastic member 31, the elastic member 35 is formed of, for example, elastically deformable silicone rubber or a foam material. As shown in Fig. 2(a) , the elastic member 35 includes a second elastic portion 36, a third elastic portion 38, and a connecting portion 37. In this example, the elastic member 35 is a single member in which the second elastic portion 36, the third elastic portion 38, and the connecting portion 37 are integrally formed. The elastic member 35 is disposed in a state where it is attached to the straight portion 26-1 and the tip portion 26-2.

[0043] In this embodiment, an example is shown in which the second elastic portion 36 and the third elastic portion 38 are configured as multiple parts of a single member, but the member forming the second elastic portion 36 and the member forming the third elastic portion 38 may be provided separately.

[0044] The second elastic portion 36 abuts against the surface of the side plate 6 c of the instrument 5 (the second surface of the present invention) when the microphone holder S100 is attached to the instrument 5. The third elastic portion 38 abuts against the surface of the side plate 6 c of the instrument 5, for example, when the microphone holder S100 is attached to the instrument 5.

[0045] As shown in Figures 5(a) and 5(b), the second elastic portion 36 is formed to include a curved contour portion (e.g., an arc-shaped portion) similar to the protruding portion of the elastic member 31. Figure 5(a) schematically shows a state in which this curved contour portion is pressed against the back plate 6b. This contour portion may have a shape defined by one radius of curvature or multiple radii of curvature. In addition, the side shape (cross-sectional shape) of the second elastic portion 36 may be substantially trapezoidal (a shape in which the upper edge and side edge of a trapezoid are connected by an arc-shaped curve).

[0046] Similarly, the third elastic portion 38 is also formed to include a curved contour portion (e.g., an arc-shaped portion). This contour portion may also have a shape defined by one radius of curvature or multiple radii of curvature.

[0047] By forming the second elastic portion 36 and the third elastic portion 38 in the shapes described above, the microphone holder S100 can be attached to musical instruments 5 of various thicknesses, as shown in Figures 5(a) and 5(b).

[0048] 5(a), a recess 39 is provided between the second elastic portion 36 and the third elastic portion 38. This recess 39 is shaped so that it does not come into contact with a corner B of the instrument body when the microphone holder S100 is attached to the instrument 5 and the second elastic portion 36 and the third elastic portion 38 are in contact with the back plate 6b and the side plate 6c, respectively. The "corner B" is the portion where the back plate 6b and the side plate 6c intersect.

[0049] If the elastic member 35 were simply L-shaped rather than having a recess 39, the corner B of the musical instrument would abut against the elastic member 35. To stably secure the microphone holder S100, as can be seen from FIGS. 5( a) and 5(b), a configuration in which three points—the elastic member 31, the second elastic portion 36, and the third elastic portion 38—abut against the musical instrument body in a side view is preferred. On the other hand, a configuration in which the corner B of the musical instrument abuts against the elastic member 35 may reduce the stability of the attachment of the microphone holder S100. Therefore, a configuration in which the recess 39 is formed, as in this embodiment, is preferred because it improves the stability of the attachment. Furthermore, the recess 39 has the advantage of allowing the microphone holder S100 to be attached to musical instruments 5 of various thicknesses, as shown in FIGS. 5( a) and 5(b).

[0050] 6 is a schematic cross-sectional view showing a configuration in which a corner B of a musical instrument 5 protrudes. In musical instruments 5 such as violas and violins, the corner B typically protrudes outward beyond the end 6b' of the back plate 6b and the side plate 6c. Therefore, the recess 39 may be formed in a shape and size such that the elastic member 35 does not come into contact with the end 6b'.

[0051] (Effects of the microphone holder S100) As described above, in the microphone holder S100 of this embodiment, the microphone holder S100 is attached to the musical instrument 5 with the protruding portion 31b of the elastic member 31, the second elastic portion 36, and the third elastic portion 38 respectively abutting against the top plate 6a, the back plate 6b, and the side plate 6c of the musical instrument 5. In other words, the microphone holder S100 is attached with the third elastic portion 38 also abutting against the side plate 6c, so that the microphone holder S100 can be stably fixed to the musical instrument 5.

[0052] Furthermore, when the recess 39 is provided in the elastic member 35, the corner B of the musical instrument 5 does not come into contact with the elastic member 35, and the microphone holder S100 can be stably attached to the musical instrument 5 at three points: the first protrusion 31b, the second elastic portion 36, and the third elastic portion 38. Furthermore, as shown in Figures 5(a) and 5(b), the configuration in which the recess 39 is provided makes it possible to favorably attach the microphone holder S100 to musical instruments 5 of various thicknesses.

[0053] Furthermore, when the elastic member 35 is a single member in which the second elastic portion 36 and the third elastic portion 38 are integrally formed, there is no need to attach the member forming the second elastic portion 36 and the member forming the third elastic portion 38 to the extension portion 26 of the second clamp member 25, respectively, and the microphone holder S100 can be manufactured with good workability.

[0054] Furthermore, with regard to the protrusions of the first protrusion 31b and the second elastic portion 36, if these protrusions are protrusions that include curved contour portions defined by one radius of curvature or multiple radii of curvature, the microphone holder S100 can be attached to instruments 5 of various thicknesses, as shown in Figures 5(a) and 5(b).

[0055] Furthermore, in this embodiment, the support member 11 extends in a direction coaxial with the rotation axis L1 and is configured to be rotatable around the rotation axis L1. As a configuration in which the structural part for holding the microphone 1 is rotatable in this manner, for example, a configuration in which the rotation axis is located away from the rotation axis L1 is also conceivable. While such a configuration is within the scope of the present invention, if the rotation axis of the support member 11 coincides with the rotation axis L1, the force for rotating the support member 11 is unlikely to act on the microphone holder S100 as a rotation moment that rotates the entire microphone holder S100. Therefore, for example, when adjusting the position of the microphone 1 with the microphone holder S100 attached to the musical instrument 5, the position of the microphone holder S100 is unlikely to shift. Therefore, problems such as the microphone holder S100 damaging the musical instrument 5 due to a shift in the position of the microphone holder S100 are unlikely to occur.

[0056] (Variations) In the above-described embodiment, the first protrusion 31b-1 and the second protrusion 31b-2 of the elastic member 31, and the second elastic portion 36 and the third elastic portion 38 of the elastic member 35 have protrusions including curved contour portions, but it is not necessary that curved contour portions be provided in each portion.

[0057] Fig. 7 is a perspective view showing another example of a microphone holder. The microphone holder S101 in Fig. 7 includes a microphone holding portion 110 and an attachment mechanism 120. The microphone holding portion 110 has a configuration similar to that of the microphone holding portion 10 of the above-described embodiment.

[0058] The attachment mechanism 120 corresponds to the attachment mechanism 20, and has a first clamp member 121 and a second clamp member 125. In the microphone holder S101, the first clamp member 121 is provided with an elastic member 131, and the second clamp member 125 is provided with an elastic member 135. The elastic member 131 is configured in the same manner as the elastic member 31 of the above-described embodiment. The elastic member 135 has a recess 135a formed in a shape that follows part of the outer periphery of a cylinder.

[0059] The microphone holder S101 configured in this manner can be used to attach the microphone 1 (see FIG. 1) to a musical instrument such as a flute.

[0060] In the above-described embodiment, a configuration has been described in which the microphone holder for holding the microphone and the mounting mechanism for attaching the microphone to the musical instrument are separate components. However, the present invention is not limited to this. The microphone holder may be provided as part of the mounting mechanism. For example, a configuration may be adopted in which a protrusion is formed on a part of the first clamp member or the second clamp member, and the shaft of the microphone is fitted into a cup portion formed on the protrusion.

[0061] Second Embodiment The microphone holder of the present invention may be provided so that the components do not come into contact with the side surface of the main body of the musical instrument. An example of the microphone holder will be described below with reference to Figs. 8 to 10. Fig. 8 is a side view of the microphone holder of the second embodiment. Fig. 9 is a diagram showing the microphone holder of Fig. 8 attached to the musical instrument. Fig. 10 is a diagram for explaining the function of the protrusions.

[0062] As in the first embodiment, the microphone holder S102 includes an attachment mechanism 20' as shown in Fig. 8. The microphone holder S102 has the same configuration as the first embodiment, except that the attachment mechanism 20' is provided with a convex elastic portion 34 and the shape of the elastic member of the second clamp member 25 is different from that of the first embodiment. Descriptions of the same configuration as the first embodiment will be omitted or will be explained briefly.

[0063] The first clamp member 21 of the microphone holder S102 has an elastic member 31 and a convex elastic portion 34. The elastic member 31 has, for example, the same shape as that shown in Figures 1 and 2.

[0064] The convex elastic portion 34 is provided on the first clamping member 21 closer to the rotation axis L1 than the elastic member 31. In this example, the convex elastic portion 34 is made of elastically deformable silicone rubber or foam material. As can be seen from FIG. 8 , the convex elastic portion 34 has a mountain-like shape in side view. The amount of protrusion of the convex elastic portion 34 from the first clamping member 21 is greater than the amount of protrusion of the elastic member 31. Specifically, the convex elastic portion 34 has an apex 34a, an inner surface 34b, and an outer surface 34c. The inner surface 34b has a bow-like concave shape. How the convex elastic portion 34 abuts against the main body of the instrument will be described later.

[0065] The second clamping member 25 has an elastic member 35'. The basic configuration of the elastic member 35' is similar to that of the elastic member 35 (see FIG. 2). The elastic member 35' differs from the elastic member 35 in that it has a thick side portion 38' instead of the third elastic portion 38 (see FIG. 2). The thick side portion 38' protrudes toward the side of the instrument when the microphone holder S102 is attached to the instrument. The thick side portion 38' has a protrusion 38a. In this example, the protrusion 38a is the portion that protrudes the most from the second clamping member 25.

[0066] (Attaching the microphone holder S102) The microphone holder S102 is attached to the musical instrument 5 in the manner shown in Fig. 9. Specifically, in this state, the elastic member 31 abuts against the surface of the top plate 6a (first surface member), and the convex elastic portion 34 abuts against the end 6a' of the top plate 6a. In other words, the top plate 6a is held down by the elastic member 31 and the convex elastic portion 34.

[0067] The second elastic portion 36 of the elastic member 35 abuts against the back plate 6b (second surface member) that faces the top plate 6a (first surface member). The thick side surface portion 38' of the elastic member 35 does not abut against the side plate 6c that forms the side of the instrument 5. In addition, the connecting portion 37 does not abut against the end of the back plate 6b.

[0068] According to the configuration of this embodiment, even if the thick side portion 38' is not in contact with the side of the main body portion 6 of the instrument, the mounting mechanism 20' clamps the main body portion 6 with the elastic member 31, the convex elastic portion 34, and the second elastic portion 36 in contact with the main body portion 6, and the microphone holder S102 is stably attached.

[0069] In musical instruments 5 such as violins and violas, sound reverberates within the main body 6. Therefore, in the case of instruments 5 and / or microphones for which vibration noise due to such reverberation can be a problem, a configuration in which the components of the microphone holder S102 do not abut against the main body 6 (specifically, a configuration in which the mounting mechanism does not abut against the side plate 6c) is advantageous in reducing noise by preventing vibrations from the main body 6 from being transmitted to the microphone. Furthermore, such a configuration also prevents the attachment of the microphone holder S102 from impeding vibrations of the main body 6 of the instrument and affecting the tone of the instrument.

[0070] (Structure for preventing incorrect installation) Incidentally, when the convex elastic portion 34 is provided, it is conceivable that a user may mistakenly install the microphone holder S102 so that the main body 6 is sandwiched between the convex elastic portion 34 and the second elastic portion 36. To prevent such installation, the thick side surface portion 38′ has a protrusion 38a.

[0071] As shown in Fig. 10 , the protrusion 38a abuts against the side surface (side plate 6c) of the musical instrument 5 when the main body 6 is about to be sandwiched between the convex elastic portion 34 and the second elastic portion 36. In the state shown in Fig. 10 , the microphone holder S102 has not moved to a position where the main body 6 can be sandwiched between the convex elastic portion 34 and the second elastic portion 36. In this way, the protrusion 38a prevents the microphone holder S102 from moving to a position where the main body 6 can be sandwiched between the convex elastic portion 34 and the second elastic portion 36.

[0072] In Figure 10, the top 34a of the convex elastic portion 34 is in contact with the end 6a' of the front panel 6a, but since the end 6a' has a curved shape, in this state the microphone holder S102 cannot be attached to the main body 6.

[0073] As described above, in this embodiment, the projection 38a is provided on the thick side surface portion 38', thereby preventing the microphone holder S102 from being attached incorrectly.

[0074] Furthermore, since the inner surface 34b has a bow shape when viewed from the side, the user can visually understand that the convex elastic portion 34 is not the part that should be in contact with the surface of the top panel 6a.

[0075] In addition to the shapes shown in Figures 8 to 10, the microphone holder may be formed, for example, so that the protrusion 38a protrudes more, thereby preventing the convex elastic portion 34 from contacting the front panel 6a in the state shown in Figure 10.

[0076] The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by functionally or physically distributing or integrating in any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combination also have the effects of the original embodiments.
