## Abstract

The present invention relates to a high-efficiency, full range acoustic resonator that functions as a high musical definition loudspeaker. It does not require electrical filters (crossover filters). The electrical signal from the amplifier directly passes to a single speaker, without energy losses and added distortions. Further, the acoustic resonator of the present invention does not require a loudspeaker enclosure to accommodate the speakers.

## Claims

### Claim 1

An acoustic resonator comprising:
a speaker placed inside a larger diameter portion of a tapered nozzle;
a duct connected, at one end, to a smaller diameter portion of said tapered nozzle, and at the other end, connected to a musical wind instrument, whereby the air produced by said speaker passes through said tapered nozzle and duct, and enters into said wind musical instrument, making it resonate.

### Claim 2 (depends on 1)

The acoustic resonator of claim 1, wherein the tapered nozzle is made up by two inner hollow profiles, a first cylindrical profile in said larger diameter portion of said tapered nozzle, that allows said speaker to be placed inside said tapered nozzle, and a second tapered profile in said smaller diameter portion of said nozzle, that allows directing the air produced by said speaker to said duct.

### Claim 3 (depends on 1)

The acoustic resonator of claim 1, wherein said duct is “U”-shaped.

### Claim 4 (depends on 1)

The acoustic resonator of claim 1, wherein said duct is made from brass.

### Claim 5 (depends on 1)

The acoustic resonator of claim 1, wherein said musical wind instrument is selected from the group consisting of a trumpet, flute, trombone, English horn, French horn, saxophone and other wind instruments.

### Claim 6 (depends on 5)

The acoustic resonator of claim 5, wherein said musical wind instrument is a trumpet.

### Claim 7 (depends on 5)

The acoustic resonator of claim 5, wherein said trumpet further comprises a mouthpiece.

### Claim 8 (depends on 1)

The acoustic resonator of claim 1, wherein said resonator components are set on a support with a base.

### Claim 9 (depends on 1)

The acoustic resonator of claim 1, wherein said speaker is a full range speaker.

### Claim 10 (depends on 9)

The acoustic resonator of claim 9, wherein said full range speaker is a high efficiency speaker.
