Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an open earphone with adjustable angle. Background Technique

[0002] An ear-hook earphone refers to an earphone with an auxiliary suspension decoration added to the side of the earphone for convenient use. Different from in-ear earphones, the ear hook is a type of earphone and earplug divided according to the wearing method.

[0003] The ear hooks of some ear-hook earphones on the market can rotate and swing up and down. In order to realize the up and down swing of the ear hook, the usual method is to set an elastic member and a tooth groove between the ear hook shell and the earphone shell to limit the swing position of the ear hook. With this design, as the use time increases, the tooth groove connection will wear, and the virtual position will increase, resulting in a short service life.

[0004] For example, a new earphone ear hook rotation structure disclosed in the application number: CN202222893899.7. The fixed seat further includes a groove opened on the surface part, and a spring and a top column are arranged in the groove, wherein the spring is sleeved on the top column. A tooth platform is further provided at the top of the top column, and the spring is installed below the tooth platform; the top column is integrally T-shaped; the top of the tooth platform is arc-shaped. The spring makes the tooth platform of the top column stuck in the tooth groove on the circular shaft hole. After the top column and the tooth groove are worn under this design, the virtual position will increase, and the service life is short.

[0005] Another example is an ear-hook type TWS earphone with a rotatable and adjustable speaker cover disclosed in the application number: CN202321786319.2. An elastic fixing piece is arranged in the speaker lower cover, and an elastic gear for fixing the speaker upper cover protrudes outwards at the middle position of the elastic fixing piece. A plurality of gear grooves are arranged in parallel on the inner wall of the speaker lower cover and are matched with the elastic gear. That is, the elastic gear of the elastic fixing piece is clamped into the gear groove to control the up and down swing of the ear hook. This design also has the problem that after the gear groove is worn, the virtual position will increase, and the service life is short. Content of the Utility Model

[0032] The present application provides an adjustable-angle open earphone, which includes an ear hook 10 and a main unit 20; the main unit 20 includes a housing 210, a circuit board 220, a speaker 221, and a battery 222, and the circuit board 220, the speaker 221, and the battery 222 are arranged inside the housing 210; the housing 210 is provided with a mounting seat 212, and a damping ring 218 is arranged in a mounting groove 213 on the mounting seat 212; a first elastic sheet 216 is arranged beside the mounting seat 212; the ear hook 10 includes an ear hook housing 110 and an ear hook 120, the ear hook housing 110 is swingably arranged on the mounting seat 212, and the swing angle of the ear hook housing 110 is between 0 and 60°; the first elastic sheet 216 presses on the limiting teeth 111; the ear hook housing 110 is provided with limiting teeth 111 and a first bushing 112; the inner bottom wall of the first bushing 112 is annularly provided with bumps 113, and the bumps 113 press on the damping ring 218; the ear hook housing 110 is further provided with a second bushing 114; the ear hook 120 is provided with a connecting shaft 121, and the connecting shaft 121 is rotatably inserted into the second bushing 114; the rotation angle of the connecting shaft 121 is between 0 and 90°. There is an installation cavity inside the housing 210, and the circuit board 220, the speaker 221, and the battery 222 are arranged in this installation cavity. When the ear hook 10 and the main unit 20 are assembled together, the ear hook housing 110 can swing up and down on the mounting seat 212, and the first elastic sheet 216 arranged beside the mounting seat 212 presses on the limiting teeth 111 arranged on the ear hook housing 110, and the cooperation between the first elastic sheet 216 and the limiting teeth 111 realizes the first-stage limit; at the same time, the first bushing 112 rotates on the mounting seat 212, and the annular bumps 113 on the inner bottom wall of the first bushing 112 press on the damping ring 218, so that the cooperation between the bumps 113 and the damping ring 218 realizes the second-stage limit.
