20140056462 | Electro-acoustic transducer - An electro-acoustic transducer includes a frame; a cover covering the frame, a magnetic system assembled with the frame, a vibration system having a diaphragm and a driving coil assembled with the frame, conductive terminals assembled with the frame, and an wireless charging coil supported by the frame. The conductive terminals include a pair of first terminals connecting to the driving coil and a pair of second terminals connecting to the wireless charging coil. The present electro-acoustic can provide wireless charging function. | 02-27-2014 |
20130329919 | Portable electronic device with bone conduction speaker - Disclosed is a portable electronic device. The portable electronic device includes a main board and a bone conduction speaker electrically coupled with the main board. When the portable electronic device is used in a high-noise environment, the main board drives the bone conduction speaker for enabling its user to perceive the sound wave. | 12-12-2013 |
20130328669 | Tactile Sensation Transmission System - Disclosed is a tactile sensation transmission system. The tactile sensation transmission system includes a first device for receiving a tactile signal and outputting a communication signal, a communication network for receiving and outputting the communication signal from the first device, and a second device for receiving the communication signal from the network and restoring the communication signal to a driving module for driving a vibration module to generate a tactile sensation on the second device. | 12-12-2013 |
20130266162 | Coil - A coil for a transducer includes a pair of first sections, a second section connecting to two ends of the first sections, and a third section connecting the other two ends of the first sections for forming a closed loop. The third section includes a pair of first stretch parts each extending from one first section toward the other stretch part, and a first extruding part extending from the first stretch parts away from the second section. The present coil can optimize the performance of the speaker. | 10-10-2013 |
20130266161 | Coil - A coil for a transducer includes a pair of first sections, a second section connecting two ends of the first sections, and a third section connecting the other two ends of the first sections for forming a closed loop. The third section includes a pair of first stretch parts each extending from one first section toward the other stretch part, and a first concave part extending from the first stretch parts toward the second section. | 10-10-2013 |
20130266160 | Coil - A coil includes a first section, a second section spaced from the first section, a third section and a forth section connecting ends of the first and second sections for forming a closed loop. The third section includes a first portion directly contacting to the first section, and a second portion extending from the first portion and directly connecting to the second section, the first portion forms a protrusion away from the fourth section. | 10-10-2013 |
