Electronic ear protection devices
Electronic ear protection devices are provided herein. In accordance with one aspect of the invention, an electronic ear protection device comprises a pair of ear cups, each comprising a speaker, and a headband that interconnects and supports the pair of ear cups on opposite ends of the headband. The device also includes an electronic sound control module disposed outside of the ear cups. The module comprises one or more microphones configured to detect an ambient sound, and one or more inputs operable to control a volume of the ambient sound signal delivered to the speakers.
1. An electronic ear protection device, comprising:
a pair of ear cups, each having a speaker therein;
a headband positioned above the pair or ear cups; and
a pair of arms that connect the pair of ear cups to opposite ends of the headband; and
an electronic sound control module attached to the headband, the module comprising:
one or more microphones configured to detect an ambient sound and generate a corresponding ambient sound signal,
one or more inputs operable to control a volume of the ambient sound signal delivered to the speakers in the ear cups via one or more cables that extend from the electronic sound control module to the speakers, and
circuitry operable to process the ambient sound signal and to communicate the processed ambient sound signal to the speakers in the ear cups via the one or more cables,
wherein a user can actuate the one or more inputs of the electronic sound control module attached to the headband to thereby control the volume of ambient sound provided to the user through the speakers in the ear cups.
2. The device of claim 1 , wherein the circuitry is configured to provide different amounts of amplification to certain frequencies relative to other frequencies when processing the ambient sound signal.
3. The device of claim 1 , wherein the circuitry is configured to filter out the ambient sound signal having a decibel level greater than a predetermined decibel level.
4. The device of claim 1 , wherein the one or more inputs comprise one or more buttons.
5. The device of claim 1 , wherein a user can actuate the one or more inputs to thereby turn the power of the circuitry on or off.
6. The device of claim 1 , wherein the electronic sound control module comprises a first unit attached to a first end of the headband and a second unit attached to a second end of the headband opposite the first end of the headband, wherein the first unit includes the one or more inputs.
7. The device of claim 6 , wherein the second unit comprises one or more batteries housed therein.
8. The device of claim 6 , wherein the first unit comprises a first microphone operable to detect the ambient sound from a first direction, and the second unit comprises a second microphone operable to detect the ambient sound from a second direction different from the first direction.
9. The device of claim 8 , wherein the circuitry is configured to control sound output to the speaker of one of the pair or ear cups based on ambient sound captured by the first microphone and to separately control sound output to the speaker of the other of the pair of ear cups based on ambient sound captured by the second microphone.
10. The device of claim 1 , wherein the electronic sound control module further comprises an electronic sound control module housing, wherein the housing houses the circuitry and the one or more microphones therein.
11. The device of claim 1 , wherein the electronic sound control module attached to the headband is in communication with the speaker in each of the pair of ear cups via one or more wires.
12. An electronic ear protection device, comprising:
a pair of ear cups, each comprising a speaker therein and an outer shell enclosing the ear cup, wherein the outer shell does not contain any exposed openings;
a headband that interconnects and supports the pair of ear cups on opposite ends of the headband; and
an electronic sound control module disposed outside of the ear cups, the module comprising
one or more microphones configured to detect an ambient sound and generate a corresponding ambient sound signal,
one or more user interface actuatable by a user to control a volume of the ambient sound signal delivered to the speakers in the ear cups, and
circuitry configured to process the ambient sound signal and to communicate the processed ambient sound signal to the speakers in the ear cups.
13. The device of claim 12 , wherein the electronic sound control module is coupled to at least one end of the headband and electrically connected to the speakers in the ear cups via a connector between the headband and the ear cups.
14. The device of claim 12 , wherein the electronic sound control module comprises a first unit attached to a first end of the headband and a second unit attached to a second end of the headband opposite the first end of the headband, wherein the first unit includes the one or more inputs.
15. The device of claim 14 , wherein the second unit comprises one or more batteries housed therein.
16. The device of claim 12 , wherein the circuitry is configured to filter out audio above a threshold decibel level.
17. The device of claim 12 , wherein the one or more user interface comprises one or more buttons actuatable by the user.
18. The device of claim 12 , wherein the one or more microphones comprises a first microphone operable to capture ambient sound from a first direction, and a second microphone configured to capture ambient sound from a second direction different from the first direction.
19. The device of claim 18 , wherein the circuitry is configured to control sound output to the speaker of one of the pair or ear cups based on ambient sound captured by the first microphone and to separately control sound output to the speaker of the other of the pair of ear cups based on ambient sound captured by the second microphone.
20. The device of claim 12 , wherein the circuitry provides frequency-dependent amplification to at least the ambient sound signal.
21. The device of claim 12 , wherein the electronic sound control module disposed outside of the ear cups is in communication with the speaker in each of the pair of ear cups via one or more wires.
