Description
Technical field
This utility model is related to a kind of piano, specifically a kind of hybrid Digital piano.
Background technology
Traditional piano is made up of keyboard, hammered string instrument, hammerhead, string, brandreth and soundboard, bulky, heavy, and difficulty is removed
Fortune.Traditional piano passes through to tap string sounding, due to string tension variation, so needing frequent tuning, and because timber exists
It may occur that deforming during humiture change, so needing to keep indoor temperature and humidity that large change does not occur.And due to being that machinery strikes
Dismiss sound and can not control volume, when night, exercise was played, can be affected other people.
And general digital piano is by plastics keyboard, digital sound source and loudspeaker composition are although Maintenance free, and can adjust
Whole volume, but plastics keyboard due to material and varies in weight, and also sensor is pressure transducer, can affect player's touching
Dynamics.Player cannot be allowed to complete dynamics and emotional expression as the wooden keyboard of traditional piano is the same with complicated frame for movement,
And sound horn cannot show the acoustic characteristics such as overtone and the sympathetic response of traditional piano.
Utility model content
The purpose of this utility model is to provide a kind of hybrid Digital piano, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides following technical scheme：
A kind of hybrid Digital piano, including keyboard machinery, keyboard sensing system, digital sound source, power amplifier, adds shake
Device and soundboard, described keyboard machinery is adopted as wooden frame for movement, and described keyboard machinery is made up of keyboard and hammered string instrument, and keyboard is
Lever construction, one end is used for playing, and the other end connects hammered string instrument；Described keyboard sensing system includes being arranged on each described key
The infrared optical sensor of tray bottom, each described infrared optical sensor all includes an infrared launcher and infrared receiver
, by Infrared irradiation in the bottom of keyboard, infrared receiving device is arranged on the underface of keyboard for device, wherein infrared launcher,
Keyboard sensing system is connected in the way of electric wiring with digital sound source；Described digital sound source is a kind of hardware device, digital
Source of sound is provided with an input interface and an output interface, and input interface connects keyboard sensing system, and output interface connects
Power amplifier, power amplifier connects plus shake device；Described plus shake device is made up of permanent magnet, coil, spring leaf, resonance surface and shell,
Wherein permanent magnet is fixed inside the housing, and coil passes through spring leaf and cage connection, and the another side of coil is resonance surface, resonance surface
It is installed in the surface of soundboard by glue or screw；Described soundboard is wooden thin plate.
As further scheme of the present utility model：Described hammered string instrument is trigonometric expression hammered string instrument（GP hammered string instrument）Or vertical hit
String machine（UP hammered string instrument）.
As further scheme of the present utility model：Described power amplifier can be integrated with digital sound source.
Compared with prior art, the beneficial effects of the utility model are：With existing primary sound piano ratio at present, by adjustment
The intensity of the acoustical signal that digital sound source produces realizes that volume is adjustable, due to not needing the structures such as the complicated iron plate of piano, string, its
Overall structure is lighter, and sound is produced by electronic equipment, without temperament；Compared with existing digital piano at present, using with
The identical frame for movement of primary sound piano, and adopt photoelectric sensor, need not contact with machinery, so not interfering with
Velocity, good hand touch, using the pronunciation of wooden soundboard, rather than speaker is it is possible to produce as conventional acoustic piano
Abundant overtone and sympathetic response, sound is true, the advantage having primary sound piano and digital piano concurrently, have portable construction, good tone color,
Good hand touch and need not manual temperament advantage, possess good marketing.
