Embodiment Construction

[0022] In this section, we will explain several preferred embodiments of the invention with reference to the accompanying drawings. Whenever the shapes, relative positions, and other aspects of components described in the embodiments are not clearly defined, the scope of the present invention is not limited only to the illustrated components, which are for illustration purposes only. Additionally, while numerous details are set forth, it is understood that some embodiments of the invention may be practiced without these details. In other instances, well-known structures and techniques have not been shown in detail in order not to obscure the understanding of this description.

[0023] figure 1A cross-sectional side view of one embodiment of a transducer is shown. The transducer 100 may be, for example, an electroacoustic transducer that converts an electrical signal into an audible signal that can be output from a device in which the transducer 100 is integrated. For exampl...

Abstract

A speaker includes a frame and a magnet assembly coupled to the frame. The magnet assembly forms an air gap through which magnetic flux is directed. The speaker also includes a voice coil suspended in the air gap, a diaphragm coupled to the voice coil, and a compliant suspension member for suspending the voice coil within the air gap. The suspension member includes a conductive duplex member for providing electrical connection between the voice coil and an electrical circuit coupled to the frame.

Description

technical field [0001] One embodiment of the invention relates to a transducer, such as a loudspeaker, having a compliant suspension member that provides an electrical connection between a voice coil and the electrical terminals of the transducer. 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, electromechanical transducers that convert electrical audio signals into corresponding sounds. More specifically, horn amplifiers and earpiece receivers can benefit from improved audio performance. However, smartphones don't have enough room for larger high-fidelity sound output devices. This is true for some portable personal co...
