[0043] Following, specific embodiments of the present application are illustrated by way of example, and other advantages and benefits of the present application will be apparent from this description to those skilled in the art. The present application can be implemented or applied in other different embodiments, and various modifications or changes can be made to the details of the present application without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0044] It should be noted that the diagrams provided in the following examples only illustrate the basic concept of the present application in a schematic manner, and only the components related to the present application are shown in the diagrams, not the number, shape and size of the components when actually implemented. The actual implementation of each component can be changed arbitrarily in terms of shape, number and proportion, and the layout of the components can be more complex.

[0045] The conventional piano has a relatively large sound when playing, and requires a higher playing environment. The use of a piano in a family can easily cause sound disturbance between neighbors. To solve this problem, the present application proposes a piano with a double working mode, and it is also desired that the piano can have the same playing feeling in the normal playing mode and the mute playing mode. To this end, based on the existing piano structure, the following considerations are designed: The conventional piano mute function needs to set a barrier between the hammer and the string to prevent the hammer from hitting the string. The piano string striking is usually fixed, and the distance from the starting position of the hammer to the striking position is also fixed. The top rod and the striking device must be separated before the hammer hits the string, and the distance between the hammer and the string when separated should be close enough to ensure the playing feeling. However, due to the existence of the barrier in the mute state of the piano, the movable distance of the hammer is shortened, and the top rod and the striking device cannot be separated before the hammer is blocked, which affects the playing feeling.

[0046] As shown in Figure 1a , a schematic diagram of the hammer 1 hitting the string 2 of the piano in the non-mute playing mode (i.e. normal playing mode) in the prior art is shown. As shown in Figure 1b , in the mute playing mode of the piano, the mute barrier 3 will move to a predetermined position close to the hammer 1, thereby blocking the hammer 1 from hitting the string 2 to achieve the mute effect of the piano. Referring to the dashed lines of Figure 1a and Figure 1b , however, under the blocking of the mute barrier 3, the movement distance of the hammer 1 changes (shortens), and the top rod cannot be separated from the striking device, which causes the player to feel that the key is stuck when playing, thereby changing the playing feeling and resulting in poor playing experience, which cannot meet the requirements of the player for the feeling.

[0047] The application provides a novel piano hammering machine and a piano comprising the same, so as to avoid the above problems in the prior art and enable a player to obtain the same touch feeling as using a normal piano playing mode even when using a mute piano playing mode.

[0048] The application provides a piano hammering machine, comprising: a telescopic hammering machine support comprising a hammering machine support and a telescopic mechanism; one end of the telescopic mechanism is connected with a piano backboard, and the other end is connected with the hammering machine support; the telescopic mechanism controls the movement distance of the hammering machine support relative to the piano backboard; wherein the hammering machine support is provided with a hammer; the piano backboard and the hammering machine support are provided with a piano string therebetween, and the string and the hammer are provided with a mute blocking object therebetween.

[0049] In the normal piano playing mode, the telescopic mechanism controls the hammering machine support to be located at an initial position close to the string, and the mute blocking object is located at an initial position away from the hammer, so that the hammer can hit the string.

[0050] In the mute piano playing mode, the telescopic mechanism controls the hammering machine support to move to a preset position away from the string, and the mute blocking object moves to a predetermined position close to the hammer, so as to block the hammer from hitting the string.

[0051] In an embodiment of the application, the hammering machine support is further provided with a top rod and a turning hammer; the turning hammer is connected with a handle of the hammer.

[0052] In the mute piano playing mode, the hammering machine support moves to a preset position away from the string. In the preset position, the top rod and the turning hammer can be separated before the handle contacts the mute blocking object in the process of the hammer hitting the string.

[0053] In the normal piano playing mode, the hammering machine support is located at an initial position, and the hammer can hit the string. In the initial position, the displacement between a hammer head (or a string hammer head) of the hammer and a final hitting position (i.e. a contact position between the hammer and the string) of the hammer is less than or equal to 1 cm in the process of the hammer hitting the string.

[0054] Optionally, the telescopic plectrum holder further comprises a holder base; the bottom end of the plectrum holder is rotatably arranged on the holder base through a rotating shaft. For example, the upper surface of the holder base has a convex part, and the bottom end of the plectrum holder is rotatably connected to the top end of the convex part through a rotating shaft. For another example, the plectrum holder is composed of two rigid bodies, the upper part of which can rotate relative to the lower part, and the rotating shaft is located at the connection between the upper and lower parts of the plectrum holder, and the lower part is fixedly arranged on the holder base. That is, the upper rigid body of the plectrum holder can rotate relative to the lower rigid body, the connection between the upper and lower rigid bodies of the plectrum holder is connected through a rotating shaft, and the lower rigid body is fixedly arranged on the holder base.

[0055] Optionally, the top end of the plectrum holder is connected to the piano back plate through a telescopic mechanism; wherein the telescopic mechanism can drive the top end of the plectrum holder to rotate away from or close to the direction of the string. The telescopic mechanism can control the bidirectional movement of the top end of the plectrum holder. The present application does not limit the specific structure of the telescopic mechanism, which can include: manual telescopic mechanism, pneumatic telescopic mechanism or electric telescopic mechanism, etc., such as: foldable rotating shaft or hinge, threaded screw rod, telescopic rod with clamping groove, electric ejector rod, hydraulic ejector rod, pneumatic ejector rod, etc. In addition, any telescopic mechanism that controls the movement and locking of the plectrum holder between the initial position and the preset position through deformation, buckling, rotation or thread can be used in the present application.

[0056] The following will be combined with Figures 2 to 7 The structure of the piano plectrum will be described in detail.

[0057] In an embodiment, the telescopic mechanism adopts a movable ejector rod 01, the left end of which is connected to the piano back plate 15 through the plectrum connecting rod 14, and the right end is connected to the top end of the plectrum holder 02. The telescopic mechanism can change the position of the plectrum holder 02 through telescopic movement. The piano can control the telescopic mechanism to perform telescopic action by calling electronic hardware electromechanical structure mode through software (that is, according to the configuration of the piano, the user can use mechanical control mode such as handle or software operation to control the telescopic mechanism to perform telescopic action through electromechanical control mode), and the specific control mode can be set according to the type of telescopic mechanism.

[0058] Specifically, as Figure 2As shown, the movable top rod 01 is in the retracted state, the piano is in the normal playing mode, the mute barrier 12 is in the initial position that does not block the hammer 03 from hitting the string 13, and the hammer 03 naturally abuts against the back barrier 04 that is fixedly arranged on the hammer mechanism support 01. The hammer mechanism support base 09 is fixed on the piano body, and in this embodiment, the upper surface thereof is provided with a protrusion, and the hammer mechanism support 02 is rotatably connected to the top end of the protrusion through the rotating shaft 08. When the movable top rod 01 is extended, the hammer mechanism support 02 can be rotated rearward. In other embodiments, the protrusion can be a separate component that is fixedly connected to the horizontal surface of the support base, rather than being an integral structure of the support base.

[0059] As shown, Figures 3 to 4 As shown, the hammer 03 is in the initial position that does not block the string 13, and the hammer 03 naturally abuts against the back barrier 04 that is fixedly arranged on the hammer mechanism support 01. The hammer mechanism support base 09 is fixed on the piano body, and in this embodiment, the upper surface thereof is provided with a protrusion, and the hammer mechanism support 02 is rotatably connected to the top end of the protrusion through the rotating shaft 08. When the movable top rod 01 is extended, the hammer mechanism support 02 can be rotated rearward. In other embodiments, the protrusion can be a separate component that is fixedly connected to the horizontal surface of the support base, rather than being an integral structure of the support base.

[0060] Figure 3 As shown, the hammer 03 is in the initial position that does not block the string 13, and the hammer 03 naturally abuts against the back barrier 04 that is fixedly arranged on the hammer mechanism support 01. The hammer mechanism support base 09 is fixed on the piano body, and in this embodiment, the upper surface thereof is provided with a protrusion, and the hammer mechanism support 02 is rotatably connected to the top end of the protrusion through the rotating shaft 08. When the movable top rod 01 is extended, the hammer mechanism support 02 can be rotated rearward. In other embodiments, the protrusion can be a separate component that is fixedly connected to the horizontal surface of the support base, rather than being an integral structure of the support base.

[0061] As shown, Figure 5As shown, the mute blocking object 12 has been in the position (i.e. the predetermined position) that can block the hammer 03 from hitting the string 13, at this time the piano is in the mute playing mode. Since the movable jack 01 is still in the retracted state, when the hammer handle 03a (referred to as the hammer handle) is blocked by the mute blocking object 12, the lower end of the jack 05 does not touch the jack adjuster 06, and the beater 03b cannot be separated from the upper end of the jack 05, so at this time the player will feel that the key is stuck when playing the piano. This is the result of using the mute device on the traditional string striking machine with no displacement or rotation of the support, and it can be avoided by using the present application.

[0062] It should be noted that the mute playing mode or normal mute playing mode of the piano is selected by the user (i.e. the player) according to his own needs. The user can start the movement of the electromechanical mute blocking object by operating the software or button, or manually control the movement of the mechanical mute structure (i.e. the mute blocking object) by the pure mechanical pull rod. Further, the user can control the movement of the mute blocking object by calling the electromechanical structure of the electronic hardware through the software.

[0063] As shown in Figures 6 to 7 As shown, the movable jack 01 is fully extended, thereby driving the string striking machine support 02 to rotate backward and stop at the preset position. At this time, the piano is in the mute playing mode.

[0064] Figure 6 As shown, after the player presses the piano key, the hammer is in the process of hitting the string, the upper end of the jack 05 lifts the beater 03b, and the beater handle 03a is at the critical position before being blocked by the mute blocking object 12. At this critical position, the lower end of the jack 05 is blocked by the jack adjuster 06, and the beater 03b is about to be separated from the upper end of the jack 05.

[0065] Figure 7 As shown, in the process of the hammer hitting the string, the upper end of the jack 05 has been separated from the beater 03b under the limitation of the jack adjuster 06. After the separation, the beater 03b continues to rotate by inertia until the beater handle 03a is blocked by the mute blocking object 12, the hammer head 03c does not hit the string 13, the string does not sound, and the mute function is realized. At the same time, the playing feeling is not affected by the mute function, and the player feels that the playing feeling is the same as normal playing.

[0066] The present application changes the position of the hammer rest bracket to rotate an angle away from the strings in the piano mute playing mode. In the piano mute playing mode, the mute bar (i.e. mute barrier) is in the working position. Because the position of the hammer rest bracket after rotation is further away from the strings and the mute bar than the original position, when the hammer handle is blocked by the mute bar, the top of the top rod and the hammer can be separated. Thus, the player can feel the normal playing feeling.

[0067] In summary, the piano and the piano hammering machine of the present application effectively overcome the shortcomings of the prior art and have high industrial utilization value.

[0068] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
