Embodiment Construction

[0016] In this section, we will explain several preferred embodiments of the present 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 the present detailed description.

[0017] figure 1 A top plan view of one embodiment of the membrane is shown. In one embodiment, membrane 100 is sized to generate acoustic waves when integrated within a driver. The driver may be, for example, an electroacoustic transducer (eg, a speaker) having a membrane 100 ...

Abstract

A speaker assembly membrane including a sound radiating surface (SRS) having a first material; a substantially planar SRS ring positioned concentrically outward from the SRS and having a second material; and a suspension member positioned concentrically outward from the SRS ring and having a third material. The second material is stiffer than the first material and the third material to locally stiffen an area surrounding the SRS and improve a breaking mode frequency of the membrane. In another embodiment, the speaker assembly membrane may include a diaphragm having a first material density; a substantially planar stiffening ring extending radially outward from an outer edge of the diaphragm and having a second material density; and a suspension member extending radially outward from an outer edge of the stiffening ring and having a third material density. The second material density is greater than the first material density and the third material density.

Description

technical field [0001] Embodiments of the present invention relate to a three-part membrane having rigid regions to improve the acoustic performance of the driver within which the membrane can be implemented. Other embodiments are also described and claimed herein. Background technique [0002] Whether listening to an MP3 player on the road or listening to a hi-fi stereo system at home, consumers are increasingly choosing in-canal and trans-auricular headphones for their listening enjoyment. Both types of electro-acoustic transducer devices have a relatively thin housing housing the receiver or driver (earpiece speaker). The thin housing provides convenience for the wearer, but also provides very good sound quality. [0003] However, these devices do not have sufficient space for hi-fi speakers. This is true for portable personal computers such as laptops, notebooks and tablets, and to a lesser extent, desktop personal computers with built-in speakers. Such devices typic...
