Description

HEAD MULTI-DIRECTIONAL AUDIO DEVICE

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a head multi-directional audio device, more particularly to a head wearing audio device that is to broadcast sound outwardly.

2. Description of the Prior Art

Nowadays, a general earphone broadcasts sound from the internal thereof to surrounding through the internal speakers, and there are normally two types of earphone: one is ear wearing and the other is head wearing. Ear-wearing earphones are worn in the outline of an ear directly and it is very close to the tympanum of the ear, and the soft tissue of the ears may be damaged during long periods of wearing.

On the other hand, head-wearing earphones may not directly damage the tympanum of the ear so as to decrease the possibility of hurting the ear tympanum, but such earphones are usually large in size and are not convenient to be carried. Hence, for personal portable demands, the head-wearing earphone does not conform with flexibility and mobility demands.

The aforesaid ear-wearing earphones and head-wearing earphones have their advantages and disadvantages, however, both of them make sound directly towards the ears, thus the ears are sheltered while in use of the earphones. The result is that the user cannot concentrate his or her mind, has reduced sensitivity to things around them and ignores warning sounds bringing about accidents.

The conclusion is that to produce a head multi-directional audio device that is to broadcast sound outwardly shall be the best solution.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

The following preferred embodiments and figures will be described in detail so as to achieve aforesaid objects.

Reference is made to Fig. 1A, Fig. 13, Fig. 2A, Fig. 2B, Fig. 3A, Fig. 3B, and Fig. 4, showing the illustration of the first preferred embodiment of the head multi-directional audio device of the present invention, including a schematic 3-D structural view, a schematic 3-D folding view, a schematic 3-D exploding view of a broadcasting device, a schematic 3-D assembling view of the broadcasting device, a schematic cross view of the broadcasting device, a schematic sounding view of the broadcasting device, and a schematic application view.

As shown in figures, the head multi-directional audio device includes a head-wear member 1, which has two broadcasting devices 11, one buffer structure 12 and two folding portions 13. The two broadcasting devices 11 have two sounding portions 1111 at the two external sides thereof, the two broadcasting devices 11 are extended toward the right hand side and left hand side of the head-wear member 1 individually, wherein the folding portion 13 lets the broadcasting device 11, extended from the head-wear member 1, be bent inwardly. The device also includes two shelters 2, each having four braces 21 that are to support the shelter 2 on the two sounding portions 1111. At least one sound exit 23 is among the four braces 21 on the each sounding portion 1111, so that the sound from the sounding portion 1111 can be broadcasted by the sound exit 23.
