Description
Technical field
This utility model relates to one and amplifies sensor, particularly relates to a kind of sensor that amplifies being installed on piano.
Background technology
Piano is a kind of keyboard instrument in western classicality music, is made up of 88 keys (52 white key, 36 black keys) and metallic cord soundboard.Italian's Ke Li David Stauffer profit (Bartolomeo Cristofori, 1655-1731) invented piano in 1709.
Piano range scope is from A2(27.5Hz) to c5(4186Hz), almost enumerate the whole musical sounds in Musical System, be in addition to the musical instrument that range beyond pipe organ is the widest.Piano be commonly used to solo, play again, the performance such as accompaniment, music of wrirting music and rehearse is very convenient.Player, by by the key on lower keyboard, affects the gavel that enclose carpet inside piano, then taps steel wire string and sends sound.Piano needs the nursing of timing, ensures that its tone color is constant.
But, in large-scale concert be all generally at present the sound mouth of piano arrange mike by audio transmission to sound equipment in be amplified the tonequality that piano sends, but tonequality so can be caused to change voice during transmission, do not exhibit the practical level of player.
Utility model content
The purpose of this utility model is that provides a kind of sensor that amplifies being installed on piano to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes pickup cartridge, voice-grade channel plate, air pressure output board, defeated sound tube, amplify chamber and connection base, described pickup cartridge is installed on the upper end of described voice-grade channel plate, described voice-grade channel plate is installed on described audio frequency output board, the lower end of described audio frequency output board is evenly arranged with some amplifying tubes, described defeated sound tube includes multiple, amplify described in being uniformly installed on chamber, the described chamber that amplifies is installed on described connection base, described defeated sound tube and described amplifying tube are on same straight line, and described defeated sound tube is provided with sealing gasket.
This utility model is preferred, some audio frequency mozzles it are evenly arranged with on described audio frequency output board, the upper center that described audio frequency mozzle is respectively arranged in described amplifying tube is corresponding with described defeated sound tube, and described audio frequency mozzle communicates with the passage on described voice-grade channel plate.
This utility model is preferred, and described defeated sound tube is identical with the quantity of described amplifying tube, and one should be at for a pair on same straight line.
This utility model is preferred, and the quantity of described defeated sound tube and described amplifying tube is eight.
The beneficial effects of the utility model are:
This utility model provides a kind of sensor that amplifies being installed on piano, is amplified to sound equipment by audio transmission by defeated sound tube, does not results in the rotten of tonequality；This utility model has simple in construction, stable performance and service life longer advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation one of a kind of sensor that amplifies being installed on piano described in the utility model；
Fig. 2 is the structural representation two of a kind of sensor that amplifies being installed on piano described in the utility model.
In figure: 1-connects base, 2-amplifies chamber, the defeated sound tube of 3-, 4-audio frequency output board, 5-passage, 6-audio frequency mozzle, 7-pickup cartridge, 8-voice-grade channel plate, 9-amplifying tube, 10-sealing gasket.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2: this utility model includes pickup cartridge 7, voice-grade channel plate 8, air pressure output board 4, defeated sound tube 3, amplify chamber 2 and connection base 1, pickup cartridge 7 is installed on the upper end of voice-grade channel plate 8, voice-grade channel plate 8 is installed on audio frequency output board 4, the lower end of audio frequency output board 4 is evenly arranged with eight amplifying tubes 9, defeated sound tube 3 includes eight, uniformly it is installed on and amplifies on chamber 2, amplify chamber 2 be installed on connection base 1 on, defeated sound tube 3 is on same straight line with amplifying tube 9, in defeated sound tube 3, sealing gasket 10 is installed, eight audio frequency mozzles 6 it are evenly arranged with on audio frequency output board 4, the upper center that audio frequency mozzle 6 is respectively arranged in amplifying tube 9 is corresponding with defeated sound tube 3, audio frequency mozzle 6 communicates with the passage 5 on voice-grade channel plate 8.
In sum, this utility model provides a kind of sensor that amplifies being installed on piano, is amplified to sound equipment by audio transmission by defeated sound tube, does not results in the rotten of tonequality；This utility model has simple in construction, stable performance and service life longer advantage.
Those skilled in the art are without departing from essence of the present utility model and spirit, various deformation scheme can be had to realize this utility model, the foregoing is only the embodiment that this utility model is the most feasible, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization this utility model description and accompanying drawing content are made, within being both contained in interest field of the present utility model.
