Abstract

A speaker includes an electroacoustic driver, a first wall that includes an integral suspension element, and a mass suspended by the suspension element to form a passive radiator. Acoustic energy from the electroacoustic driver can cause the passive radiator to move.

First claim

What is claimed is:

1. A speaker, comprising:
an electroacoustic driver;
a first wall that includes an integral suspension element; and
a mass suspended by the suspension element to form a passive radiator, whereby acoustic energy from the electroacoustic driver can cause the passive radiator to move,
wherein the suspension element is formed by removing portions of the wall.

2. The speaker of claim 1 , wherein the suspension element has a cross-section that is substantially different from another portion of the wall.

3. The speaker of claim 1 , wherein the wall is an external wall of the speaker.

4. The speaker of claim 1 , wherein the suspension element includes one or more of polypropylene and polyethylene.

5. The speaker of claim 1 , wherein the wall has a skin of metal covering at least part of the wall.

6. The speaker of claim 1 , further including a second wall to which the electroacoustic driver is secured.
