With the continuous development of audio technology, modern people have higher and higher requirements for the sound quality of audio equipment. How to make the tweeter sound fidelity is a key research direction in the material and electroacoustic industry at home and abroad. Since the high-pitched sound waves have a greater impact on the speaker dome tweeter, in order to achieve accurate and undistorted hi-fi effects, higher requirements are placed on the quality of the speaker dome tweeter. The quality of the speaker dome mainly depends on the stiffness, the internal damping, and the weight of the dome.

Why diamond as dome material? Diamond has really extraordinary characteristics to audio reproduction, a speakers dome made of diamond delivers a maximum resolution with simultaneous lowest possible distortions - the result is an absolutely unique airy, and silky music reproduction, free of noticeable harshness. Heretofore unheard details in music reproduction will be unfolded. Diamond is the perfect material for a tweeter diaphragm due to the highest sound propagation (18Km/sec.) of all known materials. Very low weight plus super high stiffness allows extreme accelerations of the dome in comparison to any other materials. No break-up in unwanted resonances in the audio band and even an octave higher, no sound compression effects. Compared with the sound velocity and elastic modulus of several tweeter materials, the diamond dome has great advantages, because it is also sufficiently "light" and "hard". The self-resonance generated during work is also the lowest, so it is easy to get a clean sound. The speaker dome with a diameter of 26mm prepared by CVD diamond has a separation frequency as high as 70kHz, which is more than twice that of AL and 40% higher than that of Be.

Diamond has the highest thermal conductivity of all materials, the dome surface supports cooling of the voicecoil. Moreover, its internal damping is also greater than Be, and the extremely high sound velocity greatly increases the resonance frequency of the diamond film, preventing harmonic components that appear after reaching a certain frequency, thereby ensuring the authenticity of sound reproduction.

In general, CVD diamond speaker film is applied to the tweeter, which has the following advantages:
1. The fastest sound propagation speed;
2. High elastic modulus;
3. Good sound-damping characteristics;
4. Lower mass density;
5. High fidelity;
6. The highest hardness;
7. Excellent high-frequency response characteristics
8. High thermal conductivity
