Abstract
Provided is an electronic keyboard instrument and sound releasing method thereof. The electronic keyboard instrument includes: a plurality of keys, a housing that supports the plurality of keys, and one or more speakers arranged in the housing. At least one of the speakers is configured as a flat-plate speaker that includes a vibrating membrane on which a pattern of a conducting wire is formed and a pair of magnet plates disposed facing both surfaces of the vibrating membrane, and the flat-plate speaker vibrates the vibrating membrane with an electromagnetic force accompanying energization of the conducting wire.
Claims19
An electronic keyboard instrument, comprising:
- a plurality of keys,
- a housing that supports the plurality of keys, and
- one or more speakers arranged in the housing;
- wherein at least one of the speakers is configured as a flat-plate speaker that comprises a vibrating membrane on which a pattern of a conducting wire is formed and a pair of magnet plates disposed facing both surfaces of the vibrating membrane, and the flat-plate speaker vibrates the vibrating membrane with an electromagnetic force accompanying energization of the conducting wire.
An electronic keyboard instrument equipped with at least one flat-plate speaker, wherein the flat-plate speaker comprises
- a vibrating membrane on which a pattern of a conducting wire is formed;
- and
- a pair of magnet plates disposed facing both surfaces of the vibrating membrane, and
- wherein the flat-plate speaker vibrates the vibrating membrane with an electromagnetic force accompanying energization of the conducting wire, and
- the electronic keyboard instrument comprises:
- a plurality of keys;
- and a housing that supports the plurality of keys;
- and
- wherein the housing comprises:
- a main body portion;
- a first opening portion that is formed on a side surface or an upper surface of the main body portion;
- a key supporting portion which protrudes to a front surface of the main body portion and supports the plurality of keys;
- and
- a second opening portion which passes through a key supporting portion, and
- wherein the flat-plate speaker is disposed inclined with respect to an opening surface of the first opening portion, or
- the flat-plate speaker is disposed in a position causing musical sounds output from the flat-plate speaker to be reflected toward a second opening portion, or
- the flat-plate speaker is disposed on each of the front surface and a back surface of the main body portion, or
- the flat-plate speaker is disposed on the upper surface of the main body portion.
A method for releasing sound of an electronic keyboard instrument, comprising:
- providing a housing for supporting a plurality of keys;
- arranging at least one flat-plate speaker in the housing, wherein the flat-plate speaker comprises a vibrating membrane on which a pattern of a conducting wire is formed and a pair of magnet plates disposed facing both surfaces of the vibrating membrane;
- and
- vibrating the vibrating membrane with an electromagnetic force accompanying energization of the conducting wire.
