## Abstract

A configuration of speaker terminals in a speaker basket. The configuration of speaker terminals has a set of conductive terminals positioned adjacent to one another on a single side of the speaker basket. The set of conductive terminals are coupled between a spider retained in the speaker basket and a connector element, also positioned on the single side of speaker basket.

## Claims

### Claim 1

A speaker basket for a loudspeaker assembly having a driver diaphragm assembly that includes a set of tinsel wires and a voice coil, a total weight of the loudspeaker assembly includes air load, the speaker basket comprising:
a basket having a center opening therein and a connector element integrated into the basket on a single side of the basket; and
a set of conductive terminals molded into the connector element, the set of conductive terminals are coupled between the center opening and the connector element, each of the conductive terminals in the set of conductive terminals are adjacent to each other within the connector and positioned on the single side of the basket, a ratio of 0.04 or less is maintained for a maximum weight of the set of tinsel wires divided by the total weight of the loudspeaker assembly.

### Claim 2 (depends on 1)

The speaker basket as claimed in claim 1 wherein each set of conductive terminals further comprises:
a first positive conductive terminal and a first negative conductive terminal; and
at least a second positive conductive terminal and at least a second negative conductive terminal.

### Claim 3 (depends on 1)

The speaker basket as claimed in claim 1 further comprising;
a spider retained in the center opening of the speaker basket for receiving a voice coil;
wherein each wire of the set of tinsel wires is woven into the spider and each wire is conductively coupled at a first end of each of the conductive terminals in the set of conductive terminals molded into the connector element and terminating at the voice coil; and
a second end of each of the conductive terminals molded into the connector element.

### Claim 4 (depends on 3)

The speaker basket as claimed in claim 3 wherein each wire in the plurality of wires is a Litz wire.

### Claim 5

A configuration of terminals in a speaker basket of a loudspeaker assembly, the speaker basket having a center opening that is conductively coupled to a spider having a set of tinsel wires, the center opening for receiving a voice coil and a connector on a single side of the speaker basket, the loudspeaker assembly has a total weight that includes air load, the configuration of terminals comprising:
a plurality of positive conductive terminals and a plurality of negative conductive terminals, each positive conductive terminal being positioned adjacent to a negative conductive terminal such that the plurality of positive conductive terminals and the plurality of negative conductive terminals are all positioned on the single side of the speaker basket having the connector;
a first conductive end of each positive and negative conductive terminal coupled to the center opening; and
a second conductive end of each positive and negative conductive terminal coupled to the connector;
wherein the plurality of positive and negative conductive terminals is molded into the connector;
wherein the connector is integrated into the speaker basket; and
a ratio of 0.04 or less is maintained for a maximum weight of the set of tinsel wires divided by the total weight of the loudspeaker assembly.
