ABSTRACT:
BACKGROUND
This present invention relates to an article that is designed to enhance a person's ability hear. It is a common understanding that a person's ear is used to collect the sound waves of various noise, and transmits onto the ear for the person to hear. However, many sounds are unheard by human ears because their loudness is insufficient for our ears to detect.
There have been several attempts to collect sound and amplify the loudness so the person can hear beyond the normal hearing. However, the most of these attempts has been with microphones, amplifiers, speakers, and headphones in order to capture, amplify, and deliver the sound audible to human ear. Although the quality of the sound thus electronically manipulated is good, the most of these sound amplifications require additional power source and additional equipment, some of them often heavy and bulky. Moreover, the effect of electronically generated electromagnetic field close to the person's ear is still being studied, and is known to have harmful effects in prolonged exposures.
Moreover, a person may prefer to hear better without electronic manipulations. This is especially true when the person wants to hear certain natural sounds, such as a bird chirping or wave breaking against a rock.
For the foregoing reasons, there is a need for a new and improved article that will enhance the sound quality for human ear naturally without electronics.
SUMMARY
This present invention relates to an article for collecting sound for ears. This invention provides improve sound quality and loudness for human ears without electronically manipulating the sound quality.
The present invention is comprised of a headband and one or more sound collectors. One or more sound collectors is attached to the headband so that when the headband is worn by the user, one or more sound collectors would be near the person's ear or ears.
As some variations to the present invention, the article for collecting sound for ears can have one or more sound collectors that is parabolic in shape such that the sound reflected off the collector surface is focused toward the ear. Moreover, as an additional variation, one or more sound collectors can have one or more parabolic impressions on the collector surface so that the sound waves would be reflected off the parabolic impressions toward the ear.
The sound collector can be of various shapes and sizes as illustrated herebelow. Also different shaped and sized sound collectors can be detachably attached to the headband to adjust the sound quality according to the user's need and preference.
