发明名称 Damper assembly for keyboard musical instruments
摘要 In the construction of a damper assembly for musical instruments, the conventionally used swingable damper lever for operationally relating a key to an associated damper wire is omitted and the swing movement of the key is either directly and indirectly converted into a corresponding fairly vertical movement of an elongated damper holder via a balance weight disposed to the bottom end of the damper holder in order to avoid undesired influences caused by swinging movement of any mechanical parts. Use of a plate type damper holder further advantageously prevents undesirable twist and dancing of the damper holder. Simultaneous, even and well-controlled pressure contact of the damper head with the vibrating string assures ideal damping and acoustic effects and use of detachable balance weight enables free adjustment of touch on the key.
