The disclosure relates to noise canceling devices and more particularly pertains to a new noise canceling device for protecting a user's ears from ambient sound. The device includes a pair of earmuffs for protecting a user's ears from ambient sound when the ambient sound is at a dangerously high volume. The device includes a microphone for streaming the ambient sounds and a pair of speakers integrated into the earmuffs for playing the ambient sounds at an adjustable volume.
The prior art relates to noise canceling devices including a variety of noise cancelling headphones that each employs electronic means of countering ambient noise. The prior art discloses a variety of noise cancelling headphones that include a microphone incorporated into an electronic noise cancellation circuit. In no instance does the prior art disclose a pair of earmuffs for hearing protection and an audio unit integrated into the earmuffs for recording ambient sounds and replaying the ambient sounds at a comfortable volume.
An embodiment of the disclosure meets the needs presented above by generally comprising a pair of earmuffs is wearable on a user's head for covering each of the user's ears. Each of the earmuffs is comprised of an acoustically insulating material thereby inhibiting ambient sound from reaching the user's ears when the earmuffs are worn to protect the user's hearing. An audio unit is integrated into the earmuffs and the audio unit has sound detecting capabilities thereby facilitating the audio unit to detect the ambient sound. The audio has sound emitting capabilities for emitting the ambient sound at an adjustable volume. In this way the user can hear the ambient sound in real time at a volume of the user's choosing thereby enhancing comfort for the user in a loud environment.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each of the earmuffs 12 has an outer shell 18 that is concavely arcuate to form a bowl shape and a pad 20 extending around an edge 22 of the bowl shape defined by the outer shell 18 such that the pad 20 abuts the user's head 14 having the outer shell 18 surrounding the user's ear 16. Furthermore, the pair of earmuffs 12 includes a head band 24 that has a first end 26 and a second end 28. Each of the first end 26 and the second end 28 is coupled to the outer shell 18 of a respective one of the earmuffs 12 has the pad 20 associated with each of the earmuffs 12 is directed toward each other. The head band 24 may comprise a central section 30 that slidably engages a pair of outer sections 32 such that the head band 24 has an adjustable length. As is most clearly shown in
An audio unit 34 is provided and the audio unit 34 is integrated into the earmuffs 12. The audio unit 34 has sound detecting capabilities thereby facilitating the audio unit 34 to stream the ambient sound in real time. The audio unit 34 has sound emitting capabilities and the audio unit 34 emits the ambient sound at an adjustable volume thereby facilitating the user to hear the ambient sound at a volume of the user's choosing. In this way the audio unit 34 enhances comfort for the user in a loud environment.
The audio unit 34 comprises a microphone 36 that is integrated into the earmuffs 12 to detect the audible sound. The microphone 36 may comprise an electromagnetic microphone of any conventional design and, as is most clearly shown in
The audio unit 34 includes a pair of speakers 40 that is each integrated into a respective one of the earmuffs 12. Each of the speakers 40 is positioned in the bowl shape defined by the outer shell 18 of the respective earmuff 12 to emit audible sound into the users' ears 16 when the user is wearing the earmuffs 12. The audio unit 34 includes an amplifier 42 that is integrated into the earmuffs 12. The amplifier 42 is electrically coupled to the preamplifier 38 thereby facilitating the amplifier 42 to amplify the audio signal received from the preamplifier 38. The amplifier 42 is electrically coupled to each of the speakers 40 thereby facilitating each of the speakers 40 to receive the amplified audio signal from the amplifier 42. Furthermore, the amplifier 42 may comprise a solid state amplifier of any conventional design that might commonly be employed in speaker circuitry.
The audio unit 34 includes a volume knob 44 that is rotatably coupled to the outer shell 18 of a respective one of the earmuffs 12 thereby facilitating the volume knob 44 to be manipulated by the user. The volume knob 44 is electrically coupled to the amplifier 42 and the volume knob 44 adjusts the amplifier 42 between a minimum volume and a maximum volume. In this way the user can adjust the volume of the ambient sound being emitted by the speakers 40.
The audio unit 34 includes a power supply 46 that is integrated into the earmuffs 12 and the power supply 46 is electrically coupled to each of the preamplifier 38 and the amplifier 42. The power supply 46 comprises a rechargeable battery 48 that is positioned in a respective one of the earmuffs 12. The rechargeable battery 48 is electrically coupled to each of the preamplifier 38 and the amplifier 42. The power supply 46 further includes a charge port 50 that is recessed into the outer shell 18 of the earmuff in which the rechargeable battery 48 is positioned. In this way the charge port 50 can insertably receive a charge cord 52 from a charger. The charge port 50 is electrically coupled to the rechargeable battery 48 for charging the rechargeable battery 48.
In an alternative embodiment 54 shown in
In use, the earmuffs 12 are worn on the user's head 14 when the user is in a loud environment, such as playing an instrument in a live performance, for example, which involves ambient sound levels that are high enough to cause hearing damage. In this way the earmuffs 12 protect the user's hearing from damage due to high volume sounds. The volume knob 44 is adjusted to facilitate the speakers 40 to emit the ambient sounds in real time at the desired volume. In this way the user can clearly hear the ambient sounds in real time at a level that is comfortable for the user thereby avoiding having their hearing damaged by the ambient sounds.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there only one of the elements.
