Abstract
The utility model relates to a standard audio frequency generator. The entirety of the utility model is in a table shape, lines of tuning bars are arranged on a table top, and resonance tubes corresponding to the tuning bars are arranged below the table top. Audio frequencies can be generated by knocking the tuning bars with a small elastic hammer. The utility model has the advantages of accurate audio frequency and loud resonance. As a musical instrument, the utility model which has graceful and soft tone color can play music of unique styles; as a standard sound calibrator, the utility model can be made into a combined standard audio frequency generator of a plurality of different frequencies for the standard sound calibration of various musical instruments.
Description
The utility model relates to a kind of acoustic instrument, particularly a kind of standard audio generator, and structure comprises pronunciation and sympathetic response device.
Various musical instruments need a kind of tuner device that produces assigned frequency when playing.Existing reed-type CALIBRATION frequency is inaccurate, error is bigger.Electronic tonometer does not have volume, and fork frequency standard but volume is not enough is used inconvenience.
The purpose of this utility model provides a kind of standard audio generator, and the sound frequency of this audio-frequency generator is accurate, the loud and clear grace of tone color, it can be used as various pipes, string and reed instrument than the sound device, itself also be a kind of musical instrument with mannerism.
The purpose of this utility model is realized by following structure:
Integral body is the platform shape, arranging an every trade pillar 2 on the table top 1, every capable pillar 2 has a small stuff 3 to contact mutually, be fixed with a rectangle tablet 4 on the small stuff 3 between per two pairs of pillars 2, the below correspondence of every tablet 4 the sympathetic response mouth of pipe 5, and each sympathetic response mouth of pipe 5 communicates with resonance tube 6 under the table top again.According to the difference of audio frequency height, the length of tablet 4 and resonance tube 6 differs.
The utility model has the advantages that:
Two of this audio-frequency generator tablet 4 fixedly places soft and on resilient small stuff 3 fulcrums, when rapping tablet 4 with resilient hand hammer, promptly can produce the natural vibration with stabilized frequency, i.e. audio frequency.The resonance tube 6 of tablet 4 belows makes the loud and clear grace of tone color again.The vibration frequency that tablet 4 produces is calculated as follows:
=C
2×S/L
2
In the formula: F: the frequency of natural vibration hertz
E: elastic feel quantity KG/CM
2
ρ: density of material G/CM
3
S: tablet thickness MM
L: tablet length M M
C1, C2: constant, by the experiment decision
The utility model is except the accurate sympathetic response of audio frequency is good, and it is loud and clear melodious also to have a tone, and the tone color grace is soft, handsome in appearance light, with low cost advantage.Can play out effect and be different from other musical instrument, the melody of unique style.
This accompanying drawing is the stereographic map of audio-frequency generator:
Below in conjunction with accompanying drawing for an embodiment:
As shown in the figure, integral body is the platform shape, arranging four group of one every trade pillar 2 on the table top 1, every capable pillar 2 has a small stuff 3 to contact mutually, be fixed with a rectangle tablet 4 on the small stuff 3 between per two pairs of pillars 2, the below correspondence of every tablet 4 the sympathetic response mouth of pipe 5, and each sympathetic response mouth of pipe 5 communicates with resonance tube 6 under the table top again.According to the difference of audio frequency height, the length of tablet 4 and resonance tube 6 differs.
Claims (2)
1. standard audio generator, structure comprises pronunciation and sympathetic response device, it is characterized in that integral body is the platform shape, arranging an every trade pillar on the table top, every capable pillar has a small stuff to contact mutually, be fixed with a rectangle tablet on the small stuff between per two pairs of pillars, the below correspondence of every tablet the sympathetic response mouth of pipe, and each sympathetic response mouth of pipe communicates with resonance tube under the table top again.
2. audio-frequency generator according to claim 1 is characterized in that the length of tablet and resonance tube differs according to the difference of audio frequency height.
