Embodiment
Below, the percussion pad of accompanying drawing to an embodiment of the present invention is used to be described.
Fig. 1 (a) is the schematic cross sectional views of the percussion pad of an embodiment of the present invention, represents non-strike state.Assuming that percussion pad of the present invention is applicable to electronic percussion instrument, but be not limited thereto, such as, also can be configured to the percussion pad being specifically designed to exercise.
This percussion pad 10 has pad portion 11, connecting portion 12, drum circle portion 13 and shell 15.Shell 15 is placed in ground, or supports on the ground via not shown support.Pad portion 11 has soft part 19 and hard part 14.The hard parts such as iron plate 14 are surrounded by as core in soft part 19.Soft part 19 is softer than hard part 14, utilizes to have the soft materials such as flexible elastomeric material and be integrally formed together with connecting portion 12 and drum circle portion 13.Hard part 14 can be assembled in soft part 19 when pad portion 11 shaping, but also can be installed to inside by embed etc. afterwards.
The strike sensor 17 be made up of piezoelectric element etc. is equipped at the inner face in pad portion 11.Hit sensor 17 and detect strike according to the vibration in pad portion 11.
The circumference in thinner wall section and connecting portion 12 connection gasket portion 11 and drum circle portion 13.The plan view shape in pad portion 11 is not limited, if but be such as circular, then connecting portion 12 and drum circle portion 13 are ring-type.
Shell 15 is fixed on by embedding etc. in drum circle portion 13.The surface in pad portion 11 and scope of attack 11a are roused the hitting part such as rod and are hit.The beating position of hitting part is the direction vertical with scope of attack 11a, and by direction that hitting part presses.Because connecting portion 12 is thin and have elasticity for wall, plays function by the elastic deformation of himself as hinge when therefore being hit in pad portion 11, allow that pad portion 11 entirety is sunk on beating position.The sense of displacement of pad portion 11 when returning to original position sunk by hitting is called the direction, opposition side of beating position.In the example of Fig. 1 (a), because drum circle portion 13 is fixed relative to shell 15 position, therefore drum circle portion 13 becomes in fact the support portion in supporting pad portion 11.That is, connecting portion 12 makes pad portion 11 pad portion 11 can be made to be supported in drum circle portion 13 at beating position and its direction, opposition side displacement.
From the side, connecting portion 12 warpage.Using on beating position, the link position relative to pad portion 11 of connecting portion 12 as the first link position P1, using the link position relative to drum circle portion 13 of connecting portion 12 as the second link position P2.Under non-strike state, the first link position P1 than the second link position P2 near the opposition side of beating position.Therefore, if with the second link position P2 for benchmark, from the side, the shape that pad portion 11 is outstanding in the opposition side of beating position is become.
Fig. 1 (b), Fig. 1 (c), Fig. 1 (d) are the schematic diagram near the pad portion 11 of the percussion pad 10 shown in Fig. 1 (a) connecting portion 12 by hitting in the stroke of beating position top offset.By hitting, connecting portion 12 is out of shape as described below.
First, if (Fig. 1 (a), Fig. 1 (b)) is hit under non-strike state, then pad portion 11 sinks on beating position, and the first link position P1 moves closer to the second link position P2 (Fig. 1 (c)).In the stroke from Fig. 1 (b) to Fig. 1 (c), the mode of texturing of connecting portion 12 compresses and be bent into main elastic deformation.Although be not limited to the situation not producing elongation in any part, produce compression and bending be almost whole region.
Depend on Beating Strength, when stronger strike, pad portion 11 sinks further on beating position, and the first link position P1 sinks (Fig. 1 (d)) gradually more than the second link position P2 on beating position.In the stroke from Fig. 1 (c) to Fig. 1 (d), compared with compression and bending, the elastic deformation of connecting portion 12 is gradually to extend.Therefore, relative to significantly hitting input, its contact becomes quiet and soft.
According to the present embodiment, under non-strike state, the first link position P1 than the second link position P2 near the opposition side of beating position.Thus, when carrying out thwack and hitting, in the pad portion 11 caused by strike in the stroke of beating position top offset, there is the leeway of reversion in the first link position P1 and the second link position P2, therefore, it is possible to guarantee large strike stroke on beating position.Therefore, it is possible to make strike sense and quietness improve.
Especially causing pad portion 11 in the stroke of beating position top offset by strike, just producing with compression at connecting portion 12 from initial and/or be bent into main elastic deformation.When moderate is hit or when thwack hits like that in the stroke of pad portion 11 to beating position displacement, when connecting portion 12 produces to extend for main elastic deformation, can first produce to compress and/or be bent into main elastic deformation before generation elastic deformation.Thereby, it is possible to it is enough large to guarantee to hit stroke.
(variation)
For connecting portion 12, under non-strike state, the first link position P1 is positioned at than the opposition side position of the second link position P2 closer to beating position, have also contemplated that except this form except Fig. 1 shownschematically except other various forms.Below, variation is represented by Fig. 2 and Fig. 3.
In the first variation shown in Fig. 2 (a), from the side, connecting portion 12 becomes linearity from the first link position P1 to the second link position P2.Overall for percussion pad 10, connecting portion can see a part for cone shape as, therefore, it is possible to keep the outward appearance being similar to acoustic drums, and strike sense and quietness is improved.
Fig. 2 (b) is the neighbouring schematic diagram under non-strike state of connecting portion 12 of the percussion pad of the second variation, Fig. 2 (c) is the neighbouring schematic diagram under strike state of connecting portion 12 of described percussion pad, Fig. 2 (d) is the neighbouring schematic diagram under non-strike state of connecting portion 12 of the percussion pad of the 3rd variation, and Fig. 2 (e) is the schematic diagram near the connecting portion 12 under strike state.
As shown in above-mentioned first variation (Fig. 2 (a)), if connecting portion 12 linearity, then when weak strike, connecting portion 12 is tightened and is not produced elastic deformation, hits just can start to produce elastic deformation due to lateral deflection by thwack above to a certain degree.Therefore, pad portion 11 can sharply sink, and therefore the property played is bad.
So, as second and the 3rd shown in variation, if arrange the bend 12a of arcuation in advance at connecting portion 12.Namely, bend 12a (Fig. 2 (b), Fig. 2 (d)) bending under being formed in non-playing state, this bend 12a in pad portion 11 by hitting in the stroke of beating position top offset, bend to the bending identical bending direction of connecting portion 12.
First, in the second variation (Fig. 2 (b)), bend 12a is arranged on the position near the first link position P1, therefore becomes to the convex arcuation in the opposition side of beating position.In the 3rd variation (Fig. 2 (d)), because bend 12a is arranged on the position of the second link position P2, therefore become to the convex arcuation of beating position.
As shown in Fig. 2 (c) and Fig. 2 (e), when by strike, from bend 12a, produce large distortion at connecting portion 12.Therefore, the such distortion sharply of lateral deflection can not be produced at connecting portion 12, but produce round and smooth flexural deformation.The intensity of bend 12a and strike improves its bending degree accordingly, and therefore the sinking in pad portion 11 can slow down accordingly with hitting power, and the property played improves.
In the example shown in above-mentioned Fig. 1 (a) ~ Fig. 1 (d) and Fig. 2 (a) ~ Fig. 2 (e), be of uniform thickness (homogeneous) of the connecting portion 12 on beating position, but in Fig. 3 (a) ~ figure (e), describe the example making thickness different according to position.If being of uniform thickness of the connecting portion on beating position 12, even if then need the degree this wall thickness being set as connecting portion 12 also can be out of shape when weak strike.If but adopt such design, be then out of shape easily when thwack hits, the displacement in pad portion 11 become excessive and be difficult to play.
Fig. 3 (a) is the neighbouring schematic diagram under non-strike state of connecting portion of the percussion pad of the 4th variation.As shown in the 4th variation, the heavy section 12b that the wall thickness be arranged on beating position at connecting portion 12 is thick.Thus, the non-heavy section 12b part of connecting portion 12 first produces elastic deformation, and after hitting power grow, heavy section 12b also produces distortion.Therefore, it is possible to guarantee that connecting portion 12 is all easily out of shape hitting from weak strike to thwack, can make to become easy by weak strike to the performance that thwack hits, strike sense is improved.
Fig. 3 (b) is the neighbouring schematic diagram under non-strike state of connecting portion 12 of the percussion pad of the 5th variation, Fig. 3 (c) is the neighbouring schematic diagram under strike state of connecting portion 12 of the percussion pad of described Fig. 3 (b), Fig. 3 (d) is the neighbouring schematic diagram under non-strike state of connecting portion 12 of the percussion pad of the 6th variation, and Fig. 3 (e) is the neighbouring schematic diagram under strike state of connecting portion 12 of the percussion pad of described Fig. 3 (d).
As shown in the 4th variation (Fig. 3 (a)), when connecting portion 12 wall thickness change sharply, depend on Beating Strength, the situation of hitting sense hardening or deliquescing suddenly may be produced.So, in the 5th and the 6th variation, the thickness of connecting portion 12 is designed to gradually change from the first link position P1 to the second link position P2.In addition, the bend 12a of arcuation is set in the side that the wall thickness of connecting portion 12 is thin in advance in the same manner as Fig. 2 (b) ~ (e).
Due to gradually changing of wall thickness, main distortion position and hitting power move from thinner wall section gradually to heavy section accordingly, no matter are therefore that weak strike or thwack hit and suitably can both absorb impact.Therefore, distortion and hitting power increase accordingly gradually, and strike sense and the property played improve.Further, by arranging bend 12a in the side that the wall thickness of connecting portion 12 is thin in advance, make distortion hit time from bend 12a more sleekly.
Further, in the 5th variation (Fig. 3 (b), (c)), the thickness of connecting portion 12 reaches maximum at the first link position P1.Therefore, connecting portion 12 is mainly out of shape near the second link position P2, substantially indeformable near the first link position P1, even if therefore pad portion 11 sinks when hitting, the change of shape of connecting portion 12 is concerning also not obvious player.Because pad portion 11 is at the basic state bottom offset keeping the shape of its periphery, therefore there is the advantage that can prevent degraded appearance.
On the other hand, in the 6th variation (Fig. 3 (d), (e)), the thickness of connecting portion 12 reaches maximum near the second link position P2.Therefore, connecting portion 12 is mainly out of shape near the first link position P1, substantially indeformable near the second link position P2, and the wall portion therefore near the second link position P2 is substantially unshift on beating position.Therefore, compared with the 5th variation, in the 6th variation, can when non-strike and strike time guarantee near the second link position P2 space (Fig. 3 (e)).Therefore, there is the part such as placement substrate and distribution 16 and make the excess room that it is not interfered with connecting portion 12 near the second link position P2 and near the position in pad portion 11, there is the advantage improving design freedom.
In addition, connecting portion 12 does not need all have wall portion at complete cycle.Particularly from the view point of raising quietness, such as, as shown in the 7th and the 8th variation of Fig. 4, its part can be cut.
Fig. 4 (a) is the planimetric map of percussion pad under non-strike state of the 7th variation, and Fig. 4 (b) is the planimetric map of percussion pad under non-strike state of the 8th variation.
As shown in the 7th variation (Fig. 4 (a)), connecting portion 12 can arrange notch 12c in a circumferential direction at certain intervals, is divided into multiple by the wall portion of connecting portion 12.Or, as shown in the 8th variation (Fig. 4 (b)), multiple aperture 12d can be formed on connecting portion 12.When hitting, air is through these notchs 12c or aperture 12d, and therefore sound diminishes.
In addition, in above-mentioned embodiment and each variation, preferred pad portion is connected with support portion via having flexible connecting portion.Support portion needs not be drum circle portion 13, can be relative to the ground not part of movement or shell 15 when hitting.Therefore, connecting portion 12 can be arranged with either one or both split in drum circle portion 13 or pad portion 11.In the key element forming percussion pad 10, drum circle portion 13 can not be comprised, also can not comprise connecting portion 12.
Above, based on preferred embodiment to invention has been detailed description, but the invention is not restricted to these specific embodiments, the present invention also comprises the various forms do not departed from the main scope of this invention.Also can carry out appropriately combined to a part for above-mentioned each variation.
