An electronic keyboard instrument is provided and methods of playing and assembling the same. The instrument comprises a controller for enabling activation of electronic signals having audible, visible, amplifiable, recordable and / or like characteristics, and a power source for operating the controller. A first keyboard is provided having a first selected length and being oriented in a first direction such that (i) audible notes of music from at least one internal sound module and / or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and / or the like may be generated and / or activated using a first hand of one or more users. A second keyboard with a second selected length is generally coextensive with and oriented generally opposite to the first such that (i) audible notes of music from at least one internal sound module and / or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and / or the like may be generated and / or activated using a second hand of the one or more users. In addition, an interface connects the controller to at least one external device having sound module, and / or sequencing and signal enhancement functions. A plurality of peripheral devices operatively connected thereto permit interactive control and manipulation of the signals. Finally, a wearable support is mounted to the instrument for suspending the first and second keyboards from the user's body during instrument operation. Alternatively, the instrument is suspended by a support structure in a generally horizontal fashion for simultaneous operation by multiple users.

An electronic device includes a device main frame portion, a display portion supported by the device main frame portion, a keyboard, and a casing on which the keyboard is disposed. The keyboard includes a plurality of operating keys, a placement base in which the plurality of operating keys are disposed, and a plurality of retaining portions disposed on at least portions of the placement base of the keyboard other than an outer circumferential portion. The keyboard is disposed on a casing. A plurality of connection retaining portions are provided on the casing, on which connection retaining portions the plurality of retaining portions of the placement base are retained, respectively.

A tone plate which makes it easy to reduce the entire length and width thereof, thus increasing the degree of freedom in design. The tone plate includes an antinode portion, front and rear ends, and first and second supporting holes which are located closer to the front and rear ends than to the antinode portion and at which a vibration node can be formed. There are provided first and second mass concentrating portions extending toward the front and rear ends from locations on a side close to the first and rear ends with respect to the supporting holes. First and second thinner portions are respectively provided between the antinode portion and the supporting holes. The tone plate vibrates to generate a musical tone of a specific tone pitch when struck with being supported at the supporting holes.
