Abstract

Embodiments for speaker terminals of a speaker assembly are provided. The speaker terminals may include a first rigid conductive structure having (i) a first input terminal configured to couple to a first output of an audio source and (ii) a first output terminal configured to couple to a first input of a voice coil, and a second rigid conductive structure having (i) a second input terminal configured to couple to a second output of the audio source and (ii) a second output terminal configured to couple to a second input of the voice coil. A speaker basket is molded about at least a portion the first rigid conductive structure and at least a portion of the second rigid conductive structure. Such a speaker basket having molded within the speaker terminals may be a component in a speaker assembly.

First claim

We claim:

a speaker basket for mounting of a speaker assembly through an opening in the speaker basket, the speaker assembly comprising a voice coil;
a first rigid conductive structure comprising (i) a first input terminal configured to couple to a first output of an audio source, (ii) a first output terminal configured to couple to a first input of the voice coil, and (iii) a first connection element that electrically connects the first input terminal to the first output terminal, the first connection element molded into the speaker basket around at least a first portion of the opening in the speaker basket; and
a second rigid conductive structure comprising (i) a second input terminal configured to couple to a second output of the audio source, (ii) a second output terminal configured to couple to a second input of the voice coil, and (iii) a second connection element that electrically connects the second input terminal to the second output terminal, the second connection element molded into the speaker basket around at least a second portion of the opening in the speaker basket.

2. The apparatus of claim 1 , wherein the first input terminal of the first rigid conductive structure is parallel to the second input terminal of the second rigid conductive structure.

3. The apparatus of claim 1 , wherein the first input terminal of the first rigid conductive structure is orthogonal to the second input terminal of the second rigid conductive structure.

4. The apparatus of claim 1 ,
wherein the first output terminal protrudes from the speaker basket for coupling to the first input of the voice coil and wherein the second output terminal protrudes from the speaker basket for coupling to the second input of the voice coil.

5. The apparatus of claim 1 , wherein the speaker assembly further comprises:
a magnetic structure coupled to the speaker basket, wherein the voice coil is magnetically suspended about a central portion of the magnetic structure.

6. The apparatus of claim 5 , wherein the speaker assembly further comprises:
a speaker cone having an inner rim and an outer rim, wherein the inner rim is coupled to the voice coil and the outer rim is coupled to the speaker basket via a surround; and
a spider coupling the voice coil to the speaker basket.

7. The apparatus of claim 5 , wherein the voice coil is configured to move axially along the central portion of the magnetic structure in response to a differential audio signal provided via the first output of the audio source and the second output of the audio source.

8. A method comprising:
forming a first rigid conductive structure comprising (i) a first input terminal configured to couple to a first output of an audio source, (ii) a first output terminal configured to couple to a first input of a voice coil, and (iii) a first connection element that electrically connects the first input terminal to the first output terminal;
forming a second rigid conductive structure comprising (i) a second input terminal configured to couple to a second output of the audio source, (ii) a second output terminal configured to couple to a second input of the voice coil, and (iii) a second connection element that electrically connects the second input terminal to the second output terminal; and
molding a speaker basket about the first connection element to position the first connection element around at least a first portion of an opening in the speaker basket and (ii) the second connection element to position the second connection element around at least a first portion of the opening in the speaker basket, wherein a speaker assembly is mountable through the opening in the speaker basket.

9. The method of claim 8 , wherein the first output terminal protrudes from the speaker basket for coupling to the first input of the voice coil and wherein the second output terminal protrudes from the speaker basket for coupling to the second input of the voice coil.

10.
