Telescopic back-hung headset

Abstract

The invention discloses a telescopic back-hung headset, including left and right headset shells (1) and a headband (2) connecting the left and right headset shells (1). The headband (2) is a wavelikebent pipeline which has moderate elasticity and plasticity and is integrally in a clamping shape, and includes a steel wire inner core (21) and a plastic tube (22) that warps the steel wire inner core(21), and the steel wire inner core (21) is buckled in buckling positions (112) of headset back shells (11) and are adhered with glue; and the plastic tube (22) sleeves tail handles (111) of the headset rear shells (11) in an interference fit mode, and when force applied to the headband (2) exceeds a designed strength, the headset (2) can bend and realize telescopic deformation, thereby changinga clamping radian. According to the headset provided by the invention, the bending radian of the headset headband can e adjusted according to the size of the head of a headset user, and thus the headset can be stably and comfortably fixed at ears of the user even if in a motion process.

Description

technical field [0001] The invention relates to an earphone, and more specifically, relates to an improvement to the head-mounted structure of the earphone. Background technique [0002] At present, with the popularity of wearable devices, people have higher and higher requirements for the comfort of earphones, and the use environment is becoming more and more complex. For example, users want to use wearable devices during exercise. Traditional earphones include earplugs and headsets. The earplugs go deep into the ear canal of the user and cause greater hearing damage. The existing headsets are heavy to wear and are located above the head. When the user is in a state of motion The stability and comfort are not ideal, and it is easy to fall off or cause discomfort to the user. In order to improve this situation, some manufacturers have introduced rear-mounted earphones, but most of the existing products are non-retractable rigid structures, which cannot well match the shape ...

Traditional earphones include earplugs and headsets. The earplugs go deep into the ear canal of the user and cause greater hearing damage. The existing headsets are heavy to wear and are located above the head. When the user is in a state of motion The stability and comfort are not ideal, and it is easy to fall off or cause discomfort to the user

In order to improve this situation, some manufacturers have introduced rear-mounted earphones, but most of the existing products are non-retractable rigid structures, which cannot well match the shape of each user's head, and cannot fundamentally Solve the problem of wearing comfort
