Furthermore, the inner walls of the three voice coils are provided with nitrogen ion adhesion layers.

Furthermore, the thickness of the three voice coil pushing parts on the hand dish body is smaller than that of the edge part of the hand dish body.

Furthermore, the three voice coils are manufactured through a water expansion process.

In a second aspect, the present application further provides a method for making a music hand dish, the method comprising the following steps:

s1, forming three circles of top voice coils which are uniformly distributed at intervals at the top end of the music hand dish by a hydroforming method, wherein the thickness of the three circles of top voice coils is smaller than that of the edge of the music hand dish;

s2, performing nitridation treatment on the top voice coil to enable nitrogen ions to be attached to the inner wall of the top voice coil, and curing at the high temperature of 800 ℃ to improve the hardness of the top voice coil.

The invention has the beneficial effects that: the beneficial effects in this application are as follows:

1. the stability of sound wave conduction is realized, the problems that the sound of the top sound is not concentrated and the conduction noise is overlarge are solved, the basic sound can be smoothly conducted on the whole metal surface, and the softness of the sound wave is increased;

2. the manufacturing cost is low, and the safety and the stability of metal are ensured;

3. a special tone is independently made through the large thickness division, and the frequency is slightly higher than the fundamental tone;

4. through nitriding treatment, metal tolerance and hardness are increased, metal vibration frequency is increased, resonance is stronger, and sound waves are longer in duration.

Detailed Description

The invention is described in further detail below with reference to the drawings and the detailed description.

Referring to fig. 1 to 4, the present embodiment provides a music hand dish 100, which includes a hand dish body 1 and three concentrically arranged top voice coils 2, the three top voice coils 2 are arranged on the top of the hand dish body 1, the three top voice coils 2 are distributed at equal intervals, wherein the depth of the top voice coil 2 at the middle position is greater than the depths of the other two top voice coils 2. In some embodiments, when the music hand dish is manufactured and molded through a die, the water is flushed to the die area corresponding to the middle three top voice coils 2 through the water expansion process treatment, so that a three-ring unique model is formed, the manufacturing cost is lower, the safety and the stability of metal are ensured, and the metal basically does not generate large variables in the stretching process.

In some embodiments, the three top voice coils 2 are preferably arranged uniformly at a pitch of 10 mm. Simultaneously in order to further guarantee the stationarity of sound wave, promote the degree of depth that is located the top voice coil loudspeaker voice coil 2 of intermediate position to 3mm to guarantee the centrality of sound wave.

In order to provide the three top voice coils 2 with a good use hardness, in some embodiments, the inner walls of the three top voice coils 2 are nitrided, that is, the inner walls of the three top voice coils 2 are provided with a nitrogen ion adhesion layer, and are cured at a high temperature of 800 ℃.

The hardness of the voice coil 2 is designed to be higher than that of other areas of the hand dish body 1, so that sound waves are conducted from a plane with lower hardness after three circles of high-frequency vibration, the overtone of the sound waves is prevented from overflowing, and simultaneously, fundamental tones resonate on the whole metal surface.

In addition, in some embodiments, the thickness of the three top voice coils 2 on the portable disc body 1 is smaller than the thickness of the edge of the portable disc body 1, preferably, for example, the thickness of the three top voice coils 2 is reduced to 9mm, the thickness of the metal outside the three top voice coils 2 is 10mm, and the thickness difference of 1mm allows the metal to resonate and generate slight vibrato.

Referring to fig. 5, an embodiment of the present application further provides a method for manufacturing a music hand disc, where the method includes the following steps:
