Abstract
An earphone has a casing that consists of a base housing (12) and a rear housing (10). The base housing and the rear housing enclose the speaker of the earphone and the base housing has an orifice (19) in it so that a wire carrying an audio signal could be provided to the speaker. The base housing is attached to the rear housing using a catch locking mechanism (22, 24). The earphone further includes a ring which fits on the position where the catch lock engages and provides added strength to catch locking mechanism. The earphone is able to withstand a drop from a height of up to 1.8 m with the ring locking mechanism in engaged position on the earphone casing. Furthermore the ring could be easily removed when the earphone requires servicing or repair and reattached for reuse without causing damage to the earphone casing.
Claims14
An earphone having a casing comprising three members, a first member and a second member encasing an earphone speaker in a cavity wherein the first member is removably interlocked with the second member to capture the earphone speaker within the casing, a circular portion of the first member elastically engaging around a circular portion of the second member and the first member being retained interlocked to the second member by a third member, the third member being a substantially inextensible annular member positionable about the first member at the point where the first member and the second member are interlocked, the annular member preventing the first member from unlocking from the second member and the annular member being capable of being removed from the point where the first member and the second member are interlocked, wherein the first member may be detached from the second member without causing damage to the first member or the second member when the annular member is removed.
A method of interlocking a first member to a second member to form an enclosed cavity capable of receiving an earphone speaker, comprising the steps of:
- elastically interlocking a circular portion of a catch member of the first member with a circular portion of a catch member of the second member,
- attaching a substantially inexpansible annular member to the first member and the second member such that the annular member encircles the interlocked catch member of the first member and the catch member of the second member,
- such that the annular member prevents the catch member of the first member and the catch member of the second member being unlocked.
