Abstract

A retaining member of a speaker motor may be formed using a mold. The mold may receive a plurality of speaker motor components. The mold may be configured to receive the speaker motor components in a desired arrangement. The mold may receive an injected material. The injected material may fill unoccupied space in the mold. The injected material may be cooled to form a retaining member to retain the speaker components in the desired arrangement subsequent to removal of the speaker motor components from the mold.

Claims

1. A method of assembling a speaker motor, the method comprising:

inserting a first speaker motor portion into a first mold portion of a mold;

inserting a second speaker motor portion into a second mold portion of the mold; and

injecting a heated material into the first mold portion and the second mold portion to form a retaining member configured to fasten the first speaker motor portion and the second speaker motor portion to one another.

2. The method of claim 1, further comprising engaging the second mold portion with the first mold portion prior to injecting the heated material.

3. The method of claim 2 further comprising:

inserting at least a first portion of an alignment device into one of the first mold portion and the second mold portion; and

receiving at least a second portion of the alignment device with the other one of the first mold and the second mold during engagement of the second mold portion with the first mold portion, wherein receipt of the alignment device aligns at least one opening in the first speaker motor portion with at least one opening in the second speaker motor portion.

4. The method of claim 2, further comprising:

cooling the retaining member;

disengaging the first mold portion from the second mold portion, where the alignment device remains in one of the first mold portion and the second mold portion; and

removing the alignment device from the one of the first mold portion and second mold portion in which the alignment device remains.

5. The method of claim 1, wherein inserting the first speaker motor portion into the first mold portion comprises inserting at least one of a top cap and a magnet into the first mold portion.

6. The method of claim 5 further comprising positioning a fixing pin to fix the magnet within the first mold portion.

7. The method of claim 6, further comprising releasing the fixing pin from the magnet subsequent to formation of the retaining member.

8. The method of claim 1, wherein inserting the second speaker motor portion into the second mold portion comprises inserting at least one of a shellpot, a magnet, and a core cap into the second mold portion.

9. The method of claim 8, further comprising positioning a fixing pin to fix the shellpot within the second mold portion.

10. The method of claim 9, further comprising releasing the fixing pin from the shellpot subsequent to formation of the retaining member.

11. A mold configured to form a speaker motor, the mold comprising:

a first cavity configured to receive a first speaker motor portion and a first portion of a retaining member formed of an injected material; and

a second cavity configured to receive a second speaker motor portion and a second portion of the retaining member.

12. The mold of claim 11, wherein each of the first cavity and second cavity is configured to receive a respective portion of an alignment collar configured to align at least one respective opening in each of the first speaker motor portion and the second speaker motor portion.

13. The mold of claim 11, comprising:

a first portion, where the first portion includes the first cavity; and

a second portion, where the second portion includes the second cavity, and where the second portion is selectively engageable with the first portion.

14. The mold of claim 13, where the first portion includes a passage configured to receive a fixing pin to fix the first speaker motor portion in the first cavity.

15. The mold of claim 11, where the first cavity is configured to receive at least one of a top cap and a magnet.

16. The mold of claim 11, where the first cavity is configured to receive at least one of a shellpot, magnet, and a core cap.

17. The mold of claim 11, where the first cavity and the second cavity are each configured to shape a respective end portion of the retaining member, where each respective portion of the retaining member is shaped to retain the first speaker motor portion and the second speaker motor portion between the respective end members.

18. A speaker motor produced by the method of:

loading a first portion of the speaker motor into a first mold portion of a mold;

loading a second portion of the speaker motor into a second mold portion of the mold; and

forming a retaining member within the mold to fasten the first portion of speaker motor to the second portion of the speaker motor.

19. The speaker motor of claim 18, where loading the first portion of the speaker motor comprises loading the first portion of the speaker motor into a first cavity formed in the first mold portion, and where loading the second portion of the speaker motor comprises loading the second portion of the speaker motor into a second cavity formed in the second mold portion.

20. The speaker motor of claim 19, where forming the retaining member within the mold comprises receiving an injected material heated into a fluid state into the first cavity and the second cavity.

21. The speaker motor of claim 20, where forming the retaining member further comprises:

receiving the heated material into a portion of the second cavity;

filling a passage with the heated liquid, where the passage is contiguously formed between the portion of the second cavity and a portion of the first cavity; and

receiving the heated material into the portion of the first cavity.

22. The speaker motor of claim 21, where forming the retaining member further comprises aligning the first cavity with the second cavity to create the passage within the first speaker motor portion and the second speaker motor portion.

23. The speaker motor of claim 22, where forming the retaining member further comprises cooling the heated material to a temperature sufficient to form the retaining member.

24. The speaker motor of claim 18 produced by the method further comprising:

fixing the first speaker motor portion in the first mold portion prior to forming the retaining member; and

fixing the second speaker motor portion in the second mold portion prior to forming the retaining member.

25. A method of forming a retaining member of a speaker motor:

positioning a plurality of speaker motor components in a mold, where the speaker components are positioned in a predetermined arrangement;

injecting a material into unoccupied space within the mold;

cooling the material to form a retaining member configured to retain the plurality of speaker motor components in the predetermined arrangement upon removal from the mold.
