  • Sheath for a flexible electrical contact
    Patent number: 7717736
    Abstract: There is provided a sheath for a flexible electrical contact that is incorporated within a sound reproduction device. The sheath preferably includes at least one opening at each end of the sheath to enable the sheath to be worn over the electrical contact with each opening having a thickened periphery ring. The main body of the sheath may be either a cylindrical shape or a conical shape. It is advantageous that the sheath damps a resonance vibration of the flexible electrical contact during operation of the sound reproduction device when the sheath is worn over the flexible electrical contact. The flexible electrical contact may be incorporated within a battery compartment of the sound reproduction device. A corresponding method of using the sheath is also disclosed.
