Problems solved by technology

Since the octave sound piece is completely fixed during frequency modulation, the sound piece cannot be measured immediately because the sound piece cannot vibrate. Therefore, the frequency measurement can only be taken out after the octave sound piece is electrolyzed. If the octave sound piece cannot meet the requirements , you need to electrolyze and measure the frequency of the octave sound piece again, and it also needs multiple treatments to meet the requirements

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0023] Such as figure 2 Shown, the octave sound piece FM device, it comprises octave sound piece 3, cathode 1, power supply 6 and electrolyte 2, the positive pole of described power supply is connected with octave sound piece 3, the negative pole of described power supply is connected with cathode 1 , Electrolyte 2 is sprayed between the sounding part of the octave sound piece and the negative electrode 1 with nozzle 5.

[0024] The above-mentioned octave sound piece can be vibrated by external force at any time, and its frequency can be measured immediately by a frequency measuring device (not shown in the figure). The measurement is performed by the Hall vibrometer sensor, so it will not be described in detail.

[0025] Such as image 3 As shown, the cut surface 12 of the above-mentioned cathode lower end surface is parallel to the electrolytic...

Abstract

The invention discloses a method for music box tablet frequency modulation. A music box tablet, a cathode, a power source and an electrolyte are adopted. A positive electrode of the power source is connected with the music box tablet, a negative electrode of the power source is connected with the cathode, the electrolyte is sprayed to the portion between the sound production portion of the music box tablet and the cathode through a spray pipe so that electrolysis can be conducted by the music box tablet and the quality of the music box tablet can be changed, the music box tablet is shifted so that real-time measurement can be conducted and the frequency of the music box tablet can be obtained until the frequency satisfies the requirement. The invention further discloses a device for music box tablet frequency modulation. Real-time frequency modulation of the music box tablet is achieved and the frequency can be adjusted at any time easily and conveniently.

Description

technical field [0001] The invention relates to a frequency modulation method and a frequency modulation device for octave sound pieces. Background technique [0002] In order to produce the correct sound, the octave sound piece needs to be FM processed. The existing octave sound pieces usually use mechanical methods to change the quality of the sounding parts of the octave sound pieces, thereby changing its frequency. This method is inconvenient to operate, and the processing is complicated, requiring multiple treatments to meet the requirements. [0003] There is also an electrolytic method for frequency modulation of the octave sound piece. The method is to place the sound piece in the electrolyte for electrolysis, and reduce the quality of the sounding part of the octave sound piece by electrolysis, thereby changing the frequency of the sound piece. figure 1 It is a device used for frequency modulation by the electrolysis method of the octave sound piece. The electrolyt...
