Description

Open wireless earphone

Technical Field

The invention belongs to the field of Bluetooth headphones, and particularly relates to an open wireless headphone.

Background

The so-called OWS, which originates from the Bose Sports Open bluetooth headset published by Bose in 2021, is characterized in that its horn is suspended over the ear of the user and does not enter the ear canal. Therefore, the problems of discomfort caused by the invasion of the earmuffs into the auditory canal and corresponding blocking of the ears of the general in-ear headphones are solved. The latter is important in outdoor exercises because the blocking ears make the runner unable to hear various warning sounds on the road, and may cause physical injury in severe cases.

This interest has been gaining attention with the popularity of TWS wireless headphones, and various follow-up products such as spring bamboo shoots after rain. But the form is roughly only structured as a Bose Sports Open, and an earring-type configuration which originates from domestic BBK, as shown in figure 1 of the specification.

Since the horn of OWS is open radiating, that is, its sound transmissions are not directed into the ear canal through the mouth of a sound, earmuff, etc., as in an in-ear earphone, there is also a lack of positioning provided by the earmuff. At present, the main stream has a structure of an ear hook and an earring, the hook part of the structure is an elastic structure, but the auricle structures of different people are different, the elastic structure cannot generate enough plasticity to absorb the difference of people, and the relative positions of the horn sounding mouth and the auditory canal mouth of OWS are different from person to person and cannot be aligned.

Therefore, the position of the sound outlet relative to the auditory canal is not fixed, the radiation of sound energy is not controlled, the sound quality is low, and the problems of excessive leakage volume and the like are caused. The latter, which hurts the privacy of the user, creates nuisance to the bystanders.
