Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a dual dynamic driver headphone. Background Technology

[0002] The concept of dual dynamic driver earphones originated from the multi-speaker design of speakers. Speakers use multiple speakers or coaxial speakers for two reasons: first, to enhance the energy of the sound through the combination of multiple speakers, especially in enhancing the energy of low frequencies; and second, to widen the frequency response range and obtain a more complete and three-dimensional sound by combining the cabinet structure and specific sound crossover methods. At the same time, the high-frequency and mid-bass speakers overlap on the diaphragm surface, making their physical positioning close to a point sound source, achieving a better sound field positioning effect. With the advent of micro dynamic driver units and the increase in earphone cavity space, manufacturers have been able to draw on the mature technology of multi-speaker speakers, and dual dynamic driver earphones have emerged. In the headphone market, consumers' demands for sound quality are increasing. Traditional single dynamic driver earphones have certain limitations in frequency response range and sound detail, while balanced armature earphones, although they have their advantages, also have the problems of complex manufacturing and high price. The emergence of dual dynamic driver earphones provides consumers with a choice that balances sound quality and cost-effectiveness, meeting consumers' needs for different music genres and high-quality music experiences.

[0003] High-quality headphones can more accurately reproduce audio signals, presenting rich musical details, such as the playing techniques of instruments and the breathing sounds of singers, making listeners feel as if they are in a live concert, enhancing the appeal and attractiveness of the music. They can clearly distinguish the layers of different instruments and sounds, making the high frequencies crisp and pleasant, the mid frequencies full and rounded, and the low frequencies deep and powerful, making the music more three-dimensional and textured, satisfying music lovers' pursuit of high-quality music. Current technology optimizes the propagation and reflection of sound waves by carefully designing the shape, size and material of the headphone cavity, enhancing the three-dimensionality and spatiality of the sound. However, this method increases the weight and volume of the headphones, affecting wearing comfort, and improper design can cause standing wave problems, interfering with sound quality. Utility Model Content
