Abstract

La présente invention concerne un module tactile, un afficheur à cristaux liquides, et un dispositif terminal. Le module tactile comprend une plaque de diffusion (1) et un diaphragme électromagnétique (2). La plaque de diffusion (1) inclut une première plaque de diffusion (11) et une seconde plaque de diffusion (12) qui sont empilées. Le diaphragme électromagnétique (2) se situe entre la première plaque de diffusion (11) et la seconde plaque de diffusion (12). Une surface avant de ce diaphragme électromagnétique (2) est assemblée étroitement avec une surface arrière de ladite première plaque de diffusion (11), et une surface arrière du diaphragme électromagnétique (2) est assemblée étroitement avec une surface avant de la seconde plaque de diffusion (12). Ledit diaphragme électromagnétique (2) se trouve entre la première plaque de diffusion (11) et la seconde plaque de diffusion (12), et il est serré fermement par cette première plaque de diffusion (11) et cette seconde plaque de diffusion (12). Par conséquent, la résistance du diaphragme électromagnétique (2) peut s'accroître, et il est possible d'éviter une déformation par gauchissement dudit diaphragme électromagnétique (2) qui aurait une incidence sur sa planéité.
