Abstract: A headphone includes two earphones attached to a headband by flexible adjusting bands for properly positioning and orienting the earphones with respect to ears of a wearer. Each earphone has a casing inside which a front-position speaker, a rear-position speaker, a middle-position speaker between the front-position and rear-position speakers and a lower-position speaker below the front-position, rear-position and middle-position speakers are arranged. The headband forms a casing inside which two top-position speakers are mounted, respectively associated with the earphones. The speakers are arranged to generate a multi-channel surrounding sound. The headphone also forms a chamber inside which a fan is fixed for generation of airflow to remove heat from the wearer.

Abstract: A device for allowing a user to pick up a telephone handset without using his or her hands is disclosed. The device includes a control unit having a control circuit arranged inside a casing. The control circuit is connected between a telephone and a handset of the telephone. A first activation key is provided on the control unit for allowing signal received by the telephone to be passed to the handset so as to allow the user to answer a phone call by hand picking up the handset. The control unit has a signal receiving/transmitting device which is coupled, via electromagnetic waves, to a counterpart receiving/transmitting device arranged in a headset. A second activation key is formed on the headset whereby the user may actuate the second activation key for allowing signals received by the telephone to be passed to the headset.

Abstract: An auxiliary apparatus comprises a rotating base, a base and a buckling piece with a long arc strip shape. The rotating base is pivoted on a bottom of the base. The bottom surface of the rotating base is adhered on a case of a mobile phone via a twin adhesive. One end of the buckling piece is connected to the base, and another end is buckled on a head of a human being via the arc shape of the buckling piece. The auxiliary apparatus makes the mobile phone firmly fixed aside of an ear of the human being without handholding.
