Abstract

A speaker sub-assembly has at least one active segment base segment, at least one batch segment, and a passive end segment. In one or more embodiments, speaker sub-assemblies with batched cones may be attached to each other by way of an adapter segment to create a dual-core speaker with batched cones. In one or more embodiments, speaker sub-assemblies with batched cones may be assembled in parallel, or linearly end-to-end.

First claim

What is claimed is:

1. A speaker assembly, comprising:
a base segment enclosure having a motor, a voice coil, and a carrier tube, a first end of the carrier tube rests above the motor, the carrier tube passes through and supports the voice coil, the base segment enclosure has a first opening in a first direction toward a resonant volume and a second opening in a second direction different than the first direction;
at least one batch segment enclosure having a cone and a carrier tube, a first end of the carrier tube of an adjacent batch segment enclosure passes through the cone and aligns with the second carrier tube of the base segment enclosure, each batch segment enclosure has a first opening in the first direction and a second opening in the second direction, wherein the first opening in the base segment enclosure aligns with the first opening in each batch segment enclosure and the second opening in the base segment enclosure aligns with the second opening in each batch segment enclosure;
an end segment enclosure having a cone and a carrier tube, the carrier tube of the end segment enclosure passes through and centers the cone, a first end of the carrier tube of the end segment enclosure aligns with a second end of the carrier tube of the at least one batch segment enclosure, a dust cap is attached to a second end of the carrier tube of the end segment;
the base segment enclosure connects to the at least one batch segment enclosure; and
the at least one batch segment enclosure connects to the end segment enclosure.

2. The assembly as claimed in claim 1 , further comprising a plurality of batch segment enclosures arranged between the base segment enclosure and the end segment enclosure, the first end of the carrier tube of a first batch segment enclosure in the at least one batch segment enclosures aligns with the second end of the carrier tube of the base segment enclosure, the second end of the carrier tube of a last batch segment enclosure in the plurality of batch segment enclosures aligns with the first end of the carrier tube of the end segment enclosure, thereby defining a first speaker with batched cones assembly.

3. The assembly as claimed in claim 2 , wherein a first speaker with batched cone assembly is aligned in parallel adjacent to at least one additional first speaker with batched cone assembly.

4. The assembly as claimed in claim 2 , further comprising at least a second speaker with batched cones assembly having a predetermined number of batch segment enclosures arranged between the base segment enclosure and the end segment enclosure, the first end of the carrier tube of a first batch segment enclosure in the plurality of batch segment enclosures aligns with the second end of the carrier tube of the base segment enclosure, the second end of the carrier tube of a last batch segment enclosure in the plurality of batch segment enclosures aligns with the first end of the carrier tube of the end segment enclosure; and
an adapter segment joining the end segment enclosure of the first speaker with batched cones assembly to the end segment enclosure of the second speaker with batched cones assembly thereby defining a dual-core speaker with batched cones.

5. The assembly as claimed in claim 4 , further comprising a plurality of dual-core speakers with batched cones arranged in parallel.

6. The assembly as claimed in claim 4 , further comprising a plurality of dual-core speakers with batched cones arranged linearly.

7. The assembly as claimed in claim 1 , wherein the carrier tube of the base segment enclosure has a first diameter at the first end and a second diameter at the second end, the second diameter is less than the first diameter.

8. The assembly as claimed in claim 1 , wherein the carrier tube of the base segment enclosure, the carrier tube of the batch segment enclosure, and the carrier tube of the end segment enclosure pass through a center of the base segment enclosure, a center of the at least one batch segment enclosure, and a center of the end segment enclosure; and
the cone in each batch segment enclosure is connected to the carrier tube in each batch segment enclosure.

9. The assembly as claimed in claim 8 , further comprising:
at least a second speaker with batched cones assembly having a predetermined number of batch segment enclosures arranged between the base segment enclosure and the end segment enclosure, the first end of the carrier tube of a first batch segment enclosure in the plurality of batch segment enclosures aligns with the second end of the carrier tube of the base segment enclosure, the second end of the carrier tube of a last batch segment enclosure in the plurality of batch segment enclosures aligns with the first end of the carrier tube of the end segment enclosure;
an adapter segment joining the end segment enclosure of the first speaker with batched cones assembly to the end segment enclosure of the second speaker with batched cones assembly thereby defining a dual-core speaker with batched cones.
