Description

This disclosure is a divisional application from Japanese Patent Application No. 2025-010691, filed on January 24, 2025, claiming priority to Chinese Patent Application No. 202420264358.4, titled "Earphone," filed with the China National Intellectual Property Administration on February 1, 2024. This application relates to the technical field of earphones, and more particularly to earphones. Earphones are devices that can convert electrical signals into sound. They are typically connected to media players, mobile phones, or other audio devices, and are worn in the ear to transmit sound to the user. Earphones are divided into two types: in-ear and over-ear. In-ear earphones typically have an earpiece, and these earphones block noise using a sealed design. When the earpiece is inserted into the user's ear canal, a sealed space is formed between the earpiece and the ear canal. However, because the sound-insulating effect of the earpiece is limited, external noise can still penetrate the earpiece and enter the ear canal. This is a schematic diagram of the earphone configuration in one embodiment of the present invention.This is a cross-sectional view along line A-A in Figure 1.This is an exploded view of an earphone in one embodiment of the present invention.This is a schematic diagram of the earpiece configuration in one embodiment of the present invention.This is a schematic diagram of the first noise-canceling unit in one embodiment of the present invention.This is a diagram showing the state when the first noise-canceling unit and the second noise-canceling unit are in contact with each other in one embodiment of the present invention.This is a diagram showing the state when the first noise-canceling unit and the second noise-canceling unit are in contact with each other in another embodiment of the present application.This is a diagram showing the state when the first noise-canceling unit and the second noise-canceling unit are in contact with each other in yet another embodiment of the present application.This is a schematic diagram of the earphone body in one embodiment of the present invention.This is a schematic diagram of the earphone configuration in another embodiment of the present invention.This is a cross-sectional view of an earphone in yet another embodiment of the present invention.
