A percussion instrument and a percussion hammer with multiple sound zones and sound chambers

Abstract

This invention discloses a multi-range violin with a sound cavity, comprising a frame body with a sound cavity and multiple violin pieces mounted on the top of the frame body via pegs. The frame body consists of a top plate, a bottom plate, and side plates forming a closed sound cavity, located at the corresponding positions of the violin pieces. A sound hole communicating with the sound cavity is provided on the top plate. The sound cavity design allows sound waves generated when the violin pieces are struck to enter the sound cavity through the sound hole. Upon hitting the inner wall of the sound cavity, some sound waves pass through the side plates into the air, while others refract back into the air, creating an echo within the sound cavity. This results in a more ethereal, mellow, and melodious sound when the violin is struck.

Description

Technical Field

[0001] The invention relates to the technical field of knocking pianos, in particular to a knocking piano with multiple sound zones and a sound cavity, and a knocking hammer acting on the knocking piano. Background Art

[0002] A percussion instrument is a piece of music that consists of multiple pieces of different lengths fixed on a stand. It can be used to strike a small piano to produce high and low frequencies. Children can also wave the hammers in their hands to make them fall on the piano board, producing pleasant octaves.

[0003] Since the sound is produced by hammering the piano pieces, manufacturers cannot completely fix the piano pieces on the piano frame during the production process, and often design the longitudinal cross-section of the piano pieces to be arc-shaped, thereby reducing the contact area between the piano pieces and the piano frame; the prior art generally opens positioning holes at both ends of the piano pieces, and fixes the piano pieces on the piano frame by passing a plurality of hard piano nails through the positioning holes on the piano pieces, and a nail cap with a diameter larger than the positioning hole is provided on the top of the piano nail to prevent the piano pieces from falling off.

[0019] (III) Beneficial effects

[0020] The percussion piano with multiple sound zones and sound cavities proposed by the present invention has the following beneficial effects compared with the prior art:

[0021] (1) The setting of the sound cavity of the present technical solution will allow the sound waves generated by the piano pieces when they are struck to enter the sound cavity through the sound holes. After the sound waves in the sound cavity hit the inner wall of the sound cavity, part of the sound waves pass through the side panels and enter the air, and part of the sound waves return to the air, allowing the sound waves to circulate in the sound cavity, forming an echo state, making the sound produced by the piano more ethereal, mellow, and more pleasant to the ears. In addition, the multiple full-tone piano pieces and semi-tone piano pieces set on the upper side of the sound cavity increase the pitch of the piano pieces, so that more songs can be played by striking the piano, meeting the needs of more players. At the same time, the multiple semi-tone piano pieces are cleverly positioned to cooperate with the full-tone piano pieces, allowing players to use existing playing methods to play.

[0022] (2) In this technical solution, by limiting the size of the piano pieces, the piano pieces can produce different tones; and by controlling the area of ​​the sound holes, the echo effect of the sound waves of the piano pieces can be controlled, so that the echo of each piano piece can be independently controlled, and the timbre and sound quality of the sound produced by striking the piano can be more accurately controlled.

[0023] (3) The technical solution effectively isolates the piano from the panel and the piano nails by providing a soft pad. This prevents the piano from coming into contact with hard materials when the piano is placed flat on a table, or upright on a table, or at any angle. There is no collision or noise between the piano and the piano nails or between the piano and the panel, which can effectively improve the sound quality of the piano.

[0046] Located at the lower side of the middle of the piano piece 2, a sound hole communicating with the sound cavity is provided in the middle of the panel 13.

[0047] In the middle of the panel 13, independent sound holes 132 are respectively opened in the middle positions of the six pieces in the bass area 211, and the plane area of ​​the independent sound holes 132 is 1.5-4.5 square centimeters; independent sound holes 132 are respectively opened in the middle positions of the five pieces in the semitone area 1 221 and the semitone area 222, and the plane area of ​​the independent sound holes 132 is 1.5-4.5 square centimeters; the shape of the independent sound holes 132 is not limited, and can be circular, rectangular, square, triangular, polygonal or other shapes; all belong to the diverse forms of the present technical solution. In this embodiment, the independent sound holes 132 are circular, and the diameter of the independent sound holes 132 is 1 cm to 1.5 cm.

[0048] In the middle of the panel 13, an integral long strip sound hole 133 is provided in the middle position of the seven piano pieces in the treble area 212. The length of the integral long strip sound hole 133 is consistent with the length occupied by the seven piano pieces on the panel 13, and the width is 1-3 cm. In the present embodiment, the width of the integral long strip sound hole 133 is 2.4 cm.

[0049] In the middle of the panel 13, an integral long strip sound hole 133 is respectively opened at the middle position of the two piano pieces of the semitone zone three part 223 and the middle position of the three piano pieces of the semitone zone four part 224. The length of the integral long strip sound hole 133 of the semitone zone three part 223 is consistent with the length occupied by the two piano pieces of the semitone zone three part 223 on the panel 13, and the length of the integral long strip sound hole 133 of the semitone zone four part 224 is consistent with the length occupied by the three piano pieces of the semitone zone four part 224 on the panel 13; the width of the integral long strip sound hole 133 is 1-3 cm. In the present embodiment, the width of the integral long strip sound hole 133 is 2.4 cm.

[0050] In the middle of the panel 13, fixing holes 131 for fixing the piano piece 2 with the piano pins 3 are respectively opened at the positions corresponding to the two ends of the piano piece 2; that is, fixing holes 131 for fixing the piano piece 2 with the piano pins 3 are respectively arranged on both sides of the sound hole, and there are multiple fixing holes 131 in each column, and the spacing between the multiple fixing holes 131 in each column is the same.

[0051] In the present embodiment, two rows of piano pieces 2 are provided, and fixing holes 131 are provided at both ends of each row of piano pieces 2. Therefore, in the present embodiment, four rows of fixing holes 131 are provided in the middle of the panel 13.

[0052] On the bottom surface of the panel 13 , reinforcing ribs 16 are fixedly connected at positions corresponding to the four rows of fixing holes 131 , and the fixing holes 131 penetrate the panel 13 and the reinforcing ribs 16 .

[0053] The length of the reinforcing rib 16 is consistent with the length occupied by the fixing hole 131 on the panel 13. The width and thickness of the reinforcing rib 16 are both about 1 cm, and the reinforcing rib 16 is obtained by pressing multiple layers of thin composite wood. The setting of the reinforcing rib 16 can facilitate the installation of the piano nail 3 and increase the stability of the piano nail 3.

[0054] An independent piano nail 3 is arranged at the position of each fixing hole 131, so there are multiple piano nails 3 in each column, and the spacing between the multiple piano nails 3 in each column is the same; the piano nails 3 are ordinary screws, including connecting columns and nail caps.

[0055] The piano piece 2 is separated from the piano nail 3 and the panel 13 by a cushion 4; the cushion 4 includes a base 41, the bottom surface of the base 41 is a plane, and contacts the top surface of the panel 13, so that the cushion 4 is placed on the panel 13 more stably. An upwardly extending connecting column sleeve 42 is provided in the middle of the cushion 4, and a through hole 421 matching the connecting column of the piano nail 3 is provided in the connecting column sleeve 42; a nail cap sleeve 43 is provided on the top of the connecting column sleeve 42, and a notch 431 matching the nail cap is provided inside the nail cap sleeve 43, and the bottom of the notch 431 is connected to the through hole 421, so as to facilitate the installation of the piano nail 3.

[0056] Located on the top surface of the base 41, protrusions 44 are provided on both sides of the connecting column sleeve 42 for contacting the bottom surface of the piano piece 2, and the top of the protrusion 44 is in an inverted cone shape.

[0057] The outer diameter of the connecting column sleeve 42 is slightly smaller than the diameter of the mounting hole on the piano piece 2, and the outer diameter of the nail cap sleeve 43 is larger than the diameter of the mounting hole on the piano piece 2; this not only facilitates the installation of the piano piece 2, but also effectively prevents the piano piece 2 from falling off.

[0058] The soft pad 4 is integrally formed by a mold and is made of soft rubber or silicone.

[0059] When installing the piano piece 2, the soft pad 4 is easy to deform due to its low hardness. You only need to squeeze the nail cap sleeve 43 of the soft pad 4 toward the middle and pass it through the installation hole of the piano piece 2, and then install the piano piece 2 on the soft pad 4. Then align the through hole 421 on the soft pad 4 with the fixing hole 131 on the panel 13. Finally, put the piano nail 3 into the through hole 421 in the middle of the soft pad 4 and tighten it with a screwdriver so that the bottom of the piano nail 3 fits tightly with the inner wall of the fixing hole 131 on the panel 13 and the reinforcing rib 16. After the piano nail 3 is installed, the nail cap of the piano nail 3 is fixed in the nail cap sleeve 43 of the soft pad 4, so that the top surface of the piano nail 3 is flush with the top surface of the nail cap sleeve 43 of the soft pad 4; or the top surface of the piano nail 3 is slightly lower than the top surface of the nail cap sleeve 43 of the soft pad 4. The piano nail 3 is completely wrapped by the soft pad 4, which protects the user and prevents the piano nail 3 from accidentally injuring the user.

[0060] The setting of the soft pad 4 effectively isolates the piano sheet 2 from the panel 13, and at the same time, effectively isolates the piano sheet 2 from the piano nails 3; prevents the piano sheet 2 from contacting with materials with greater hardness, and prevents the piano sheet 2 from colliding with the piano nails 3 and the panel 13 when it is struck, thereby generating noise; and effectively improves the sound quality of the piano sheet 2. The top of the protrusion 44 is set to an inverted cone, which effectively reduces the contact area between the piano sheet 2 and the soft pad 4, and minimizes the influence of the soft pad 4 on the amplitude of the piano sheet 2.

[0061] There is a gap between the piano piece 2 and the bottom surface of the nail cap sleeve 43, which is convenient for installation and removal of the piano piece 2. During long-term use, dirt is easily accumulated on the edge of the contact position between the piano piece 2 and the cushion 4. The long-term accumulated dirt will affect the sound quality of the piano piece 2. The setting of the gap between the piano piece 2 and the bottom surface of the nail cap sleeve 43 is convenient for cleaning the dirt on the bottom of the piano piece 2. Even in a poor environment or a long time of use, the piano can still be used normally without affecting the sound quality of the piano piece 2.

[0062] Embodiment 2:

[0063] A hammer 5 for striking a musical instrument comprises a spherical hammer body 51 and a striking rod 52; the spherical hammer body 51 and the striking rod 52 are detachably connected. The detachably connected spherical hammer body 51 and the striking rod 52 allow the spherical hammer body 51 or the striking rod 52 to be replaced; when a performer needs to play different bass notes, the spherical hammer body 51 of different hardness can be selected for replacement and installed on the striking rod 52.

[0064] The knocking rod 52 includes a hand-held portion 521 arranged at the bottom, a connecting portion 522 in the middle, and a protruding portion 523 arranged at the top for inserting into the middle of the spherical hammer body 51; the hand-held portion 521, the connecting portion 522 and the protruding portion 523 are integrally formed of plastic material. A platform 524 for supporting the spherical hammer body 51 is arranged at the connecting position of the connecting portion 522 and the protruding portion 523.

[0065] The length ratio of the hand-holding portion 521 to the connecting portion 522 is 3:2. A protrusion is provided at the position of the hand-holding portion 521 , so that the performer feels more comfortable when grasping the hand-holding portion 521 .

[0066] The bottom surface of the spherical hammer body 51 is provided with a plane section matching the platform 524 , and a cylindrical recess leading to the middle of the spherical hammer body 51 is provided at the center of the plane section. The inner diameter of the cylindrical recess is consistent with the outer diameter of the protrusion 523 .

[0067] The arrangement of the flat section of the bottom surface of the spherical hammer body 51 and the platform 524 allows the spherical hammer body 51 and the protrusion 523 to have a higher fit after installation.

[0068] The surface of the protrusion 523 is provided with convex patterns 5231 protruding from the surface, which can increase the friction between the protrusion 523 and the spherical hammer body 51, so that the protrusion 523 and the spherical hammer body 51 are installed more stably.

[0069] The spherical hammer body 51 is made of rubber, and multiple spherical hammer bodies 51 with different hardness are manufactured according to the performance requirements. Multiple spherical hammer bodies 51 with different hardness produce different sounds when they are struck on the piano, and spherical hammer bodies with different hardness can be selected according to the required bass range; the sound produced by the hammer made of wood or metal when it is struck on the piano is softer and lower; and the sound produced by the hammer made of wood or metal forms two different sound qualities. It can adapt to and meet the different performance requirements of performers.
