Publication number: 20240137688Abstract: An electronic device includes an accommodation and a receiver. The accommodating piece defines a first cavity and a second cavity communicated with the first cavity. A first sounding hole and a second sounding hole communicated with outside are respectively defined on two opposite walls of the first cavity. The receiver is installed in the first cavity. The receiver includes a first diaphragm and a second diaphragm disposed opposite to first diaphragm. The first diaphragm faces the first sounding hole. The second diaphragm faces the second sounding hole. The first diaphragm vibrates to generate a first sound signal, the second diaphragm vibrates to generate a second sound signal, and a phase of the first sound signal is opposite to a phase of the second sound signal. Parts of sound signals generating sound leakage are compensated and counteracted through an algorithm, and a user has a good private call experience.Type: ApplicationFiled: June 18, 2023Publication date: April 25, 2024Inventors: Huhu Yang, Zhaoyu Yin, Zhizhu Chen
