Abstract
A system for charging a battery (22) including a power supply (70) and a vibration device (48) to enhance charging. The vibration device (48) may be the speaker of an electronic communication device (30).
Claims7
An electronic communication device comprising:
- a rechargeable electrochemical cell for powering said communication device;
- a speaker for transmitting received audio frequency information and further adapted to ultrasonically vibrate said electrochemical cell during charging thereof;
- and
- wherein said speaker further includes switching means for switching between audio and ultrasonic frequencies.
1 more element
An electronic device, comprising:
- a cell pack for powering said electronic device;
- a speaker, having a back, disposed in said electronic device, said back of said speaker disposed against said cell pack, said speaker producing both audible and ultrasonic vibrations;
- and
- wherein said speaker vibrates said cell pack while said cell pack is being recharged to achieve an increased mass transport rate within said cell pack.
