Description

Technical Field

[0001] This invention relates to the field of headphones, specifically a Bluetooth headphone. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones can be detached from the media player and connected using only a plug, allowing for private listening without disturbing others.

[0003] Improvements are needed for Bluetooth headphones. Existing Bluetooth headphones have all the necessary components, and in-ear and over-ear styles are common in the market. However, the existing headphone channel is basically a single tube for conducting sound, with an earplug attached to the front of the tube and inserted into the ear to prevent it from falling out easily. However, the diameter of the ear canal varies, and the replacement of earplugs and the different sizes of earplugs suitable for different people mean that headphones without compatible earplugs are basically unusable.
