Abstract: A communication method for earphones which include a first earphone and a second earphone includes: the first earphone and the second earphone synchronously monitoring data sent from an intelligent terminal in a preset time sequence and performing feedback processing according to a data receiving condition; the first earphone sending out a first response signal if receiving the data; or the first earphone sending no response signal if not receiving the data; and the second earphone sending no response signal if receiving the data or the second earphone sending a second response signal if not receiving the data. By implementing embodiments of the present disclosure, the two earphones can synchronously receive data sent from the intelligent terminal, so that the communication reliability is improved. In addition, the two earphones give responses in different manners, so that power consumption of the earphones is reduced.

Abstract: A speaker includes a vibration diaphragm, a voice coil, a first magnet, and a second magnet. Each of the first and second magnets includes an end adjacent to the voice coil and an end distant from the voice coil, of which magnetic polarities are opposite to each other. The ends of the first magnet and the second magnet that are adjacent to the voice coil are of opposite magnetic polarities. The voice coil is partly aligned with a gap between the first magnet and the second magnet. A portion of the voice coil is located between the end surfaces of the first and second magnets that exhibit a height difference. Due to the height difference, a path of the magnetic lines of force is shortened and the magnetic flux density in an area around the voice coil is thus increased, thereby increasing the BL value of electromechanical coupling factor.

Abstract: A planar diaphragm speaker includes an enclosure, a vibration diaphragm assembly, and two magnet assemblies fixed in the enclosure. The vibration diaphragm assembly is arranged between the two magnet assemblies and spaced from the two magnet assemblies. The magnet assemblies each include a ring-shaped outer magnet and an inner magnet with a magnetic gap formed therebetween. The vibration diaphragm assembly includes a vibration diaphragm and a voice coil. The vibration diaphragm is formed with a trough. An effective-width portion of the voice coil spans over the magnetic gap. The planar diaphragm speaker with a simple structure can effectively increase the thickness of the voice coil without increasing a vibration compartment height, and provide, through collaboration with a dual-side magnetic circuit structure, a 360° dead zone free magnetic field to enhance the sensitivity and low frequency performance of the planar diaphragm speaker, exhibiting excellent utilization.

Abstract: Disclosed are a multiplexing structure for a wireless antenna and a touch pad of a touch sensor, and a wireless wearable device. The multiplexing structure includes a radiating touch pad, a first conductor, a first circuit, a second circuit, and a frequency dividing circuit. The radiating touch pad is configured to receive and transmit an RF signal and receive a touch signal. The first conductor is electrically connected to the radiating touch pad. The first circuit is electrically connected to the radiating touch pad through the first conductor. The frequency dividing circuit is electrically connected to the second circuit and the first conductor, and is located between the second circuit and the first conductor. The multiplexing structure can separate the touch signal and the RF signal, and can solve the problem of mutual signal interference in the wireless wearable device caused by space limitation.
