## Abstract

A miniature speaker is describer including a microphone holder and a vibrator holder. A miniature speaker matching the oval shape of a sound chamber is placed face down over the sound chamber. A small slot is formed in one of the sides of the sound chamber to provide a sound portal through which the speaker generated sound is heard. The platform on which the sound chamber is formed also comprises a microphone holder and a vibrator holder. The microphone holder is positioned such that a sound receiving portal of the microphone is orthogonal to the sound portal formed in one of the side walls of the sound chamber.

## Claims

### Claim 1

A miniature speaker enclosure, comprising:
a) a sound chamber formed on a platform from a smooth resilient material;
b) a miniature speaker mounted face down over said sound chamber; and
c) sound exits the sound chamber through a small slot formed in a side wall of the sound chamber

### Claim 2 (depends on 1)

The miniature speaker enclosure of claim 1, wherein the sound chamber is an oval shape matched by shape of the miniature speaker.

### Claim 3 (depends on 2)

The miniature speaker enclosure of claim 2, wherein the sound chamber is approximately about four millimeters deep with a flat bottom.

### Claim 4 (depends on 2)

The miniature speaker enclosure of claim 2, wherein the sound chamber has a sloped bottom that is sloped downward toward the side wall comprising the small slot.

### Claim 5 (depends on 1)

The miniature speaker enclosure of claim 1, wherein the smooth resilient material that forms the sound chamber is ABC plastic.

### Claim 6 (depends on 1)

The miniature speaker enclosure of claim 1, wherein said platform comprises a microphone holder and a vibrator holder.

### Claim 7 (depends on 6)

The miniature speaker enclosure of claim 6, wherein the microphone holder directs sound to a microphone orthogonal to sound output from the sound chamber.

### Claim 8

A method for creating a miniature speaker enclosure, comprising:
a) forming a platform comprising:
i) a sound chamber;
ii) a microphone enclosure; and
iii) a vibrator enclosure;
b) forming a small slot on a side of the sound chamber to provide an output portal;
c) enclosing said sound chamber by placing a speaker face down over said sound chamber;
d) positioning said microphone enclosure on said platform such that an input portal is orthogonal with said output portal; and
e) installing an assembled miniature speaker enclosure in an electronic communication device having limited space.

### Claim 9 (depends on 8)

The method of claim 8, wherein the sound chamber is oval shaped to match a shape of the speaker.

### Claim 10 (depends on 9)

The method of claim 9, wherein the sound chamber has a level bottom.

### Claim 11 (depends on 9)

The method of claim 9 wherein the sound chamber has a sloped bottom that is sloped downward toward the side wall comprising the small slot

### Claim 12 (depends on 9)

The method of claim 9, wherein the sound chamber is approximately four millimeters deep, and the external dimensions are approximately seventeen millimeters long and approximately eleven millimeters wide.

### Claim 13 (depends on 8)

The method of claim 8, wherein said small slot is five millimeters wide.
