Earplug earphone with adjustable external auditory canal pressure elastic ring

Abstract

The invention relates to an earplug earphone with an adjustable external auditory canal pressure elastic ring, which comprises an earphone base body and an inner core inside the earphone base body, and is characterized in that the front end of the earphone base body is provided with a sound outlet cylinder, the sound outlet cylinder is provided with a hose, a light and thin spring is arranged between the hose and the sound outlet cylinder, and the light and thin spring is connected with an inner hole surface of the hose; the middle section of the earphone base body is in threaded connection with an earphone outer sleeve, the tail end of the earphone outer sleeve is internally provided with a compression spring arranged on the earphone base body in a sleeved manner, and the earphone outer sleeve is connected with the hose; sound inlet holes in the tail end of the earphone base body are communicated with an inner hole of the hose, the tail end of the earphone base body is in threaded connection with a tail cover, the diameter of a central area of the end face of the tail cover is slightly greater than the diameter of the sound inlet holes, and the end face of the tail cover is provided with the small sound inlet holes which are uniformly distributed around the circumference of the central area; and when the earplug earphone is used, the light and thin spring rotating through the earphone outer sleeve can perform compression on the hose along the axial direction and the radial direction of the sound outlet cylinder, and the compression spring can perform compression on the earphone outer sleeve along the axial direction of the earphone base body. The earphone improves the comfort in use, and a user can also hear an external emergency sound warning while listening to the music.

Description

technical field [0001] The invention belongs to the field of earplug earphones, in particular to an earplug earphone with adjustable external auditory canal pressure elastic ring. Background technique [0002] The earplugs of existing earphones are usually made of silica gel, which is soft to the touch, strong in elongation, and very durable, so it feels very comfortable to wear. There are various types and appearances of earplugs on the market, but they generally include an earphone base and an earplug part. The earphone base is used to connect with the earphone wire and the earplug part. The face and the human ear are in contact and matched with each other, and the sealing performance between them is good. However, the earplugs made of this material are easily deformed after being inserted into the human ear due to their strong softness, so that they cannot maintain a good fit and comfort with the human ear, and they often slip during use. Lose. Contents of the inventi...
