Description

Tympanic membrane and its speaker

The novel creation refers to a tympanic membrane for a loudspeaker, and in particular to a tympanic membrane with a sputum rubber membrane flap.

With the pressure of modern people's life and the acceleration of pace, music has become an indispensable part of life's life to regulate tension and monotony, so the speakers of general consumer products (such as speakers, headphones, etc.) The sound quality of the music will affect the experience of the speaker when listening to music. With the improvement of people's living standards and spiritual pursuits, consumers' demands for sound quality are getting higher and higher. Therefore, the requirements for loudspeakers for general consumer products are increasingly valued, so improving sound quality and improving consumer experience is one. Continuous work and tasks.

In general, the speaker of the prior art vibrates the tympanic membrane when working through the speaker, allowing the sound to propagate through the tympanic membrane to the outside of the speaker, so that the user can receive the sound. Further, the invention patent No. 6,415,037 further proposes a horn structure, which mainly proposes a frame of a horn, a tympanic membrane is arranged along the periphery of the frame, and a resonant cavity is formed between the frame and the tympanic membrane, the inner side of the frame a coil is disposed in the center, so that when the coil is actuated, a magnetic line change is generated in the center of the resonant cavity, and a magnetic component corresponding to the central position of the coil is provided on the eardrum due to the magnetic lines of force The repulsion effect formed by the change, vibrating up and down, and then causing the tympanic membrane to vibrate Make noise.
