Abstract

One aspect of the present disclosure relates to high aspect ratio moving coil transducers. A voice coil former is disclosed comprising a first portion having a planar region and an out-of-plane region extending out of the plane of the planar region, and wherein a length dimension of the first portion is a width dimension of the first portion at least twice. The former also includes a second portion extending from the first portion in a direction perpendicular to the plane of the first portion, the second portion being integrally formed with the first portion and dimensioned to support the voice coil thereon.

Description

technical field [0001] Embodiments of the present invention relate to high aspect ratio moving voice coil transducers with improved voice coil stability, and more particularly, to high aspect ratio moving voice coil transducers with a one-piece high aspect ratio former for improved voice coil stability. speaker assembly. Other embodiments 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 speaker speakers and earphone receivers, which can benefit from improved audio performance. The speaker may include a moving coil motor to drive the sound output. A moving voice coil motor may include a diaphragm, a voi...
