  • Patent number: 6570994
    Abstract: A technique and apparatus for integrating a speaker with button (or keyboard) components such as a tactile membrane and/or PCB. The tactile membrane conventionally used between buttons and switch mechanisms to provide tactile feedback to a user upon depression of the button is extended to form a vibrating portion of a speaker. The vibrating portion is doped with or otherwise includes an activating material (e.g., copper) which will be physically affected by a magnetic field. The activating material may be adhered to the upper and/or lower side of the vibrating portion, or doped therein. A coil for the speaker is formed with a coil tracing pattern formed on one or more layers of a PCB. One or more amplifier circuits may be included to drive one or more coil patterns, to cause a fluctuating magnetic field in the direction perpendicular to the vibrating portion of the tactile membrane.
