Audio resonance device

The audio resonance device contains a base member having a box shape with an open top side, a resonance element inside the base member having stacked ceramic layers, and at least two contact pieces on a top side, a cover member sealing the open top of the base member, and a number of elastic elements, each contacting a contact piece of the resonance element, and having an end extending through the cover member and contacting a portable appliance for picking up audio vibration from the portable appliance and delivering the audio vibration to the resonance element. The resonance element resonates with the audio vibration, and the base member provides a resonant chamber so that the audio quality from the portable appliance is enhanced. The portable appliance is not required of any modification such as opening holes.

TECHNICAL FIELD OF THE INVENTION

The present invention is generally related to portable appliance, and more particular to au audio resonance device externally applied to a portable appliance for enhancing the audio quality from the portable appliance.

DESCRIPTION OF THE PRIOR ART

Portable appliances such as iPads, iPhones, and similar smart phones are widely popular these days due to their convenience and high intelligence. For these portable appliances to deliver audio signal, speakers are still the mainstream means. However, for a speaker to be small enough to fit in these portable appliances and to deliver audible sound, usually holes are configured on the portable appliances. The portable appliances therefore cannot achieve waterproof requirement. On the other hand, the scaled-down speaker usually cannot deliver high quality audio signal. Even through there are thinned speakers aimed to resolve the foregoing issues, the manufacturing process is complicated.

SUMMARY OF THE INVENTION

Therefore, an audio resonance device is provided herein for conveniently applied to a portable appliance so as to enhance its audio quality without modifying the portable appliance.

The audio resonance device contains a base member having a box shape with an open top side, a resonance element inside the base member having stacked ceramic layers, and at least two contact pieces on a top side, a cover member sealing the open top of the base member, and a number of elastic elements, each contacting a contact piece of the resonance element, and having an end extending through the cover member and contacting a portable appliance for picking up audio vibration from the portable appliance and delivering the audio vibration to the resonance element. The resonance element resonates with the audio vibration, and the base member provides a resonant chamber so that the audio quality from the portable appliance is enhanced. The portable appliance is not required of any modification such as opening holes.

Preferably, the cover member has a number of openings, each corresponding to a contact piece of the resonance element; and each elastic element is extended through an opening and exposed outside the base member.

Preferably, each elastic element contains a bended contact section and an extension section extended from the contact section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated inFIGS. 1 and 2, an audio resonance device A according to an embodiment of the present invention mainly contains a base member1, a resonance element2, a cover member3, and a number of elastic elements4. The base member1has a box shape with an open top side. The base member1contains a bottom side11and a circumferential wall12surrounding the bottom side11. The resonance element2contains a number of stacked ceramic layers, and has at least two contact pieces21on a top side. The cover member3has at least two openings31, each corresponding location-wise to a contact piece21. Each elastic element4contains a bended contact section41and an extension section42extended from the contact section41.

The resonance element2is positioned inside the base member1, and the cover member3seals the open top side of the base member1. Each elastic element4has its contact section41contacting a contact piece21of the resonance element2, and has its extension section42extended through an opening31of the cover member3and exposed outside the base member1. Then, by attaching the audio resonance device A to a thin portable appliance such as iPad, iPhone, the contact sections41pick up the audio vibration of the thin portable appliance and delivers the audio vibration to the resonance element2. The resonance element2resonates with the audio vibration, and the base member1provides a resonant chamber so that the audio quality from the thin portable appliance is enhanced. The thin portable appliance is not required of any modification such as opening holes.

As illustrated inFIG. 3and as mentioned above, each elastic element4has its contact section41contacting a contact piece21, and has its extension section42extended and exposed through an opening31of the cover member3. The elasticity of each elastic element4is resulted from its bended contact section41and, as the cover member3seals the base member1, each elastic element4is forced downward and its contact section41is tightly against a contact piece21so that the audio vibration is always received appropriately by the resonance element2.

FIG. 4depicts a scenario of the present embodiment applied to a thin portable appliance. As illustrated, the audio resonance device A is conveniently attached to a smart phone5by, for example, adhesion and no modification such as opening holes is required on the smart phone5.

FIG. 5depicts a scenario of a user using a thin portable appliance with the present embodiment installed. As illustrated, the audio resonance device A is attached to and resonates with the smart phone5. Then, as the user holds the smart phone5close to his ear, his ear canal B further provides a resonant chamber and the audio quality would be further enhanced. Unlike conventional devices, the smart phone5with the present embodiment installed is not required to be aimed at the user's ear appropriately. With the present embodiment, the user can clearly hear the audio signal from the smart phone5as long as the smart phone5is held in the vicinity of his ear.
