Loudspeaker having an interlocking magnet structure
First Claim
1. A loudspeaker having a magnet structure, comprising:
- a first magnet, a second magnet, a core cap disposed between the first magnet and the second magnet, and a shell pot configured to contain at least a portion of the first magnet, each of the first magnet, the second magnet, the core cap, and the shell pot having an aperture extending axially therethrough, where each of the apertures is axially aligned with one another; and
a fastener comprising an injection moldable material molded in the aligned apertures, the fastener having a first end, a second end, and a body member extending therebetween, the body member configured to extend at least partially through said aligned apertures, the first end and the second end of the fastener being positioned to capture the first magnet, the second magnet, the core cap, and the shell pot into a secure relative position.

Abstract
A magnet structure for use with a loudspeaker has an interlocking mechanism. The magnet structure can include a magnet, a shell pot and at least one core cap. The shell pot can contain the magnet in its hollow interior. The magnet can be a single magnet or double magnets. The core cap has two surfaces. For a single magnet, one surface of the core cap faces the magnet. For double magnets, the core cap can be vertically disposed between the two magnets. The magnet, the core cap and the shell pot can interlock with one another such that a position of the magnet relative to the core cap and the shell pot can be rigidly preserved. The magnet can be configured to be, for example, overlapped, inserted, staked and/or engaged with at least one of the shell pot or the core cap.

19. A loudspeaker having a magnet structure, comprising:
-
an axial assembly of components, the components comprising a first structure portion, a second structure portion, and a shell pot configured to contain at least a portion of the first structure portion, each of the axial assembly components having an aperture extending axially therethrough, the apertures being axially aligned with one another to define an axial opening of the axial assembly; and a non magnetic fastener having a first head member, a second head member, and a body member extending between the first and second head members, the fastener being molded into the axial opening of the axial assembly so that the body member extends at least partially through said axial opening, and the first and second head members are disposed adjacent a first end and a second end of the axial opening, respectively, the first and second head members being sized greater than the respective first and second ends of the axial opening in order to capture the first structure portion, the second structure portion, and the shell pot into a secure relative position. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method for manufacturing a magnet structure for use with a loudspeaker, comprising:
-
providing a first structure portion, a second structure portion, and a shell pot configured to contain at least a portion of the first structure portion, each having an aperture extending axially therethrough; arranging the first structure portion, the second structure portion, and the shell pot to form an axial assembly so that all of the apertures are in axial alignment with one another; placing the axial assembly in an injection molding machine; and injecting material with the injection molding machine into the axially aligned apertures of the axial assembly to form a fastener configured to capture the first structure portion, the second structure portion, and the shell pot into a secure relative position. - View Dependent Claims (30, 31, 32, 33)
