Problems solved by technology

In this way, if the positional relationship between the movable part and the driving part becomes inappropriate due to the deformation and displacement of the vibrated body, there will be deformation of the damper connecting the movable part and the driving part, making the drive unstable, The problem of reducing the durability of the vibrator
In addition, errors in the connection position between the body to be vibrated and the movable part may also occur during the installation of the vibrator

[0027] figure 1 It is a perspective view showing the external appearance of the vibrating unit and the musical instrument to which the vibrating unit is applied according to the first embodiment of the present invention. In the present embodiment, piano 1 which is a grand piano is exemplified as a "vibration means" which vibrates an object to be vibrated by operating an audio signal to generate sound, and a device or musical instrument to which the vibration means is applied. A soundboard 7 is exemplified as an object to be vibrated. However, it is not limited to these examples, and any structure may be used as long as the vibrator is driven by a drive signal and the vibrator vibrates the body to be vibrated.

[0028] The piano 1 has, on its front surface, a keyboard and pedals 3 that are operated by a player and that have a plurality of keys 2 arranged in a row. In addition, the piano 1 has a control device 10 having an operation panel 13 on the front part, and a touch pane...

[0055] Figure 7 It is a schematic perspective view of the vibration excitation unit provided with the drive part support part in 2nd Embodiment of this invention. In the present embodiment, a driving part supporting part 60 ( Figure 5 ), and the second drive unit support portion 62 is interposed between the base member 30 and the support body 55 of the first drive unit support portion 61 . Therefore, the driving unit supporting portion 160 is constituted by the first driving unit supporting portion 61 and the second driving unit supporting portion 62 . The structure of the first drive unit support portion 61 is the same as that of the drive unit support portion 60 except for the relationship between the base member 30 and the support body 55 . An insertion hole 45 corresponding to the insertion hole 529 is formed in the first drive unit support portion 61 .

[0056] The second driving unit supporting portion 62 has the base member 40, the stoppers 42A, 42B, and the shaft ...

Abstract

The invention provides a vibrator and a music instrument, which can improve the durability. The vibrator unit is provided with: a movable part (100) that is connected to an object to be oscillated; adrive unit (52) that vibrates the object to be vibrated by the vibration of the movable unit by driving the movable unit; and a drive section support section (60) that is fixed to the support body (55) and that rotatably supports the drive section (52) about an axis (C3) in a direction intersecting the movable direction of the movable section.

Description

technical field [0001] The present invention relates to a vibrating unit in which a movable part is driven by a driving part to vibrate a body to be vibrated by vibration of the movable part, and a musical instrument provided with the vibrating unit. Background technique [0002] Conventionally, it is known that a device such as a musical instrument is provided with a vibrator for vibrating a body to be vibrated. The vibrator operates with, for example, an audio signal, and vibrates the object to be excited to generate sound from the object to be excited. For example, in a keyboard musical instrument, a vibrator is fixed to an in-line pillar via a support member, and a movable part vibrating by inputting an electric current corresponding to an audio signal to a coil is connected to a soundboard which is a body to be vibrated. The vibration of the movable part is transmitted to the soundboard, and the vibration of the soundboard becomes sound. A mounting structure of a vibr...
