  • Patent number: 8374377
    Abstract: A speaker apparatus in accordance with the present invention is for use with a vehicle having a compartment and is to be mounted to the vehicle. The speaker apparatus includes: an interior member including a hole edge that defines an attachment hole; a speaker unit configured to be placed in the attachment hole, the speaker unit including a limiting member; and a speaker grille configured to be attached in the attachment hole from an inside of the compartment, the speaker grille including a claw-fixing portion that is bendable and is configured to be engaged with the hole edge. Accompanying the engagement of the claw-fixing portion with the hole edge, the speaker grille is fixed to the interior member. Accompanying the placement of the speaker unit in the attachment hole, the limiting member is positioned in a bending space for the claw-fixing portion and thereby prevents disengagement of the claw-fixing portion from the hole edge.

  • Patent number: 8300876
    Abstract: A method of soldering terminals of a micro-speaker on a circuit board comprises the following steps. Firstly, providing a circuit board having a pair of through holes passing therethrough, and two soldering sections defined surrounding the pair of through holes. Secondly, the soldering sections are plated with soldering tin. Thirdly, providing a pair of columned terminals, the terminal includes an upper portion, a low portion and a body connecting between the upper portion and the low portion. Fourthly, the low portion of the terminal is inserted into the corresponding through hole and the body is resisted on the soldering section. Fifthly, the soldering tin is heated to solder the body on the soldering tin. Finally, the upper portion of the terminal is soldered onto the corresponding end of the voice coil. As a result, soldering defective can be reduced.

  • Patent number: 8300873
    Abstract: A low profile miniature speaker configured for use in greeting cards such as sound generating greeting cards and other novelties. The thickness of the speaker is minimized while maintaining the sound quality and increasing strength. The speaker magnet is counter-sunk into the housing of the speaker, thereby decreasing overall thickness. The speaker is configured with concentric ribs that radiate outward from the center of the circular speaker. The ribs reinforce the plastic housing and increase the structural strength of the speaker.

    Abstract: An improved shallow speaker is disclosed having a molded diaphragm with an outer, depending, annular cylindrical subcone that connects to a channel formed in the outer perimeter of the spider. Embodiments for round and cornered (polygonal, etc.) speakers are provided. The top plate has a raised outer annular portion for receiving an annular spider flange with or without screw holes for clamping the inner spider flange with a spider ring. In the cornered speaker embodiments, flanges extend from the cylindrical portions to the cornered portions including from a diaphragm inner glue flange over the depressed central portion and from the annular cylindrical subcone both outwardly and inwardly to top diaphragm portions. Routing of the tinsel may be through one or more openings in the annular cylindrical subcone and along the diaphragm inner surfaces, with channels in or on those surfaces for securely routing the tinsel.
