## Abstract

A speaker having a heat-transfer upper bearing cup fastened to the bottom side of the cone paper, a bottom bearing cup set between the heat-transfer upper bearing cup and the damper, and a heat-transfer sound coil holder capped on the sound coil with bottom hooks thereof fastened to the heat-transfer upper bearing cup and the damper to establish with the heat-transfer upper bearing cup a heat dissipation structure for quick dissipation of heat from the sound coil during the operation of the speaker, thereby raising the output power.

## Claims

### Claim 1

A speaker, comprising a bracket, a stack of magnets and washers mounted in said bracket, a cone paper and a damper suspending in said bracket, and a sound coil sleeved onto said stack of magnets and washers, wherein the speaker further comprises a heat-transfer upper bearing cup mounted in said damper inside said bracket beneath said cone paper, said upper bearing cup having the rim thereof bonded to said cone paper, a heat-transfer sound coil holder fastened to the inside of said heat-transfer upper bearing cup and surrounding said sound coil to hold said sound coil in place and adapted for transferring heat from said sound coil to said heat-transfer upper bearing cup for dissipation, thereby raising the output power

### Claim 2 (depends on 1)

The speaker as claimed in claim 1, wherein said heat-transfer upper bearing cup comprises a plurality of equiangularly spaced mounting through holes; said damper comprises a plurality of equiangularly spaced mounting through holes corresponding to the mounting through holes of said heat-transfer upper bearing cup; said heat-transfer sound coil holder comprises a plurality of bottom hooks respectively hooked in the mounting through holes of said heat-transfer upper bearing cup and said damper.

### Claim 3 (depends on 1)

The speaker as claimed in claim 1, further comprising a bottom bearing cup mounted in said damper, said bottom bearing cup comprising a plurality of mounting through holes respectively fastened to said bottom hooks of said heat-transfer sound coil holder.

### Claim 4 (depends on 2)

The speaker as claimed in claim 2, wherein said bottom hooks of said heat-transfer sound coil holder are L-shaped hooks.
