Abstract

The present disclosure relates to a flat transducer for surface actuation, and specifically provides the transducer assembly comprising a stiffening plate having a first side and a second side; a voice coil coupled to the second side surface of the reinforcing plate; a magnet assembly positioned along a second side of the reinforcement plate, the magnet assembly being operable to generate a magnetic field that moves the magnet assembly relative to the voice coil; and a spring suspending the magnet assembly from the reinforcement plate such that movement of the magnet assembly drives movement of the reinforcement plate.

Description

technical field [0001] One aspect of the invention relates to a flat transducer for surface actuation, and more particularly, to a flat transducer with a suspension system incorporated into a magnet assembly to reduce overall thickness. Other aspects are also described and claimed. Background technique [0002] In modern consumer electronics, audio functionality is playing an increasing role as digital audio signal processing and audio content delivery continue to improve. In this regard, a wide range of consumer electronic devices could benefit from improvements in audio performance. For example, smartphones include, for example, electro-acoustic transducers such as speakers, which could benefit from improved audio performance. However, smartphones do not have enough space to accommodate transducers or other actuators with relatively large z-heights or thicknesses. This is true for some portable personal computers such as laptops, notebooks and tablets, and to a lesser e...
