Abstract

The invention discloses an EMA assembly, a mobile terminal, a sound production method and a computer storage medium, the EMA assembly comprises a support body, a slide block assembly, a swing rod, an EMA device and a driving device, and the support body is provided with a first guide rail and a second guide rail which are intersected; the sliding block assembly comprises a first sliding block arranged in the first guide rail and a second sliding block arranged in the second guide rail; the swing rod is hinged to the first sliding block and the second sliding block; the EMA device is arranged on the swing rod; the driving device comprises a first driving device for driving the first sliding block to move and a second driving device for driving the second sliding block to move; and the first driving device drives the first sliding block to reciprocate along the first guide rail, the second driving device drives the second sliding block to reciprocate along the second guide rail, and the first sliding block and the second sliding block are hinged to the swing rod, so that the swing rod is driven to rotate, an EMA device on the swing rod can be driven to change positions, sound production at a required position can be realized, and then directional sound wave transmission is realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of screen sound generation, and more specifically, to an EMA component, a mobile terminal, a sound generation method, and a computer storage medium. Background technique [0002] With the application and popularization of screen sound technology on high-end mobile phones, the application of Electro-Magnetic Actuator (EMA) is becoming more and more extensive. There are two main types of EMA devices: resonant EMA devices and direct-drive EMA devices. Resonant EMA devices can be used as non-porous earpieces and linear motors, and can be applied to flexible organic light emitting display (Organic Light Emitting Display, OLED) screens, hard OLED screens or liquid crystal display (Liquid Crystal Display, LCD) screens, but the disadvantage is sound transmission It does not have obvious directionality and large sound leakage. Direct-drive EMA devices can be used as non-porous earpieces ...
