Description

  The present invention relates to a headband multidirectional acoustic device, and more particularly to a headband acoustic device capable of broadcasting sound to the outside.

  Currently, all common earphones emit sound from the inside of the earphone to the outside through a built-in speaker. The earphones are roughly divided into an ear hook type and a headband type. Ear-mounted earphones are too close to the eardrum when applied directly to the ears, and when the earphones are worn over a long period of time, the soft tissues of the ears receive a certain amount of sound stimulation over a long period of time. Cause trouble. On the other hand, since the headband type earphone is not too close to the eardrum, damage to the eardrum can be reduced, but since the outer shape is large, it is not convenient to carry. Speaking of the requirements for personalized Walkman®, the originally required elasticity and mobility characteristics are lost.
