Claim:
1. A vibration motor assembly comprising: a capsule having a cavity; a vibration motor having a motor casing and a shaft extending through the motor casing, wherein the vibration motor is configured to rotate the shaft; an eccentric mass connected to the shaft, wherein the eccentric mass is rotatable with the shaft; an end cap having a body with a first connecting structure connecting the end cap to the vibration motor and a second connecting structure connecting the capsule to the end cap, wherein the first connecting structure comprises a first section of the body of the end cap having a first outer periphery received within a first end of the motor casing and engaging an inner surface of the first end of the motor casing to connect the end cap to the vibration motor, and wherein the second connecting structure comprises a second section of the body of the end cap having a second outer periphery that is larger than the first outer periphery, and wherein the second section is received within an open end of the capsule and engages an inner surface of the capsule to connect the capsule to the end cap; and wherein the vibration motor and eccentric mass are disposed in the cavity and, so disposed, the vibration motor and eccentric mass are enclosed by the so-connected end cap and capsule, so as to enable the vibration motor assembly to withstand fabrication conditions.
