ELECTRIC HEARING AIDS; PUBLIC ADDRESS SYSTEMS (producing sounds with frequency not determined by supply frequency G10K) ## Abstract A device for isolating a microphone from vibrations, the device comprising a frame comprising a plurality of surfaces, the plurality of surfaces laying on a plane that is different from each other and defining at least one mounting point; at least one non-resonant cord attached to the mounting point of the frame, the non-resonant cord adapted to support a microphone and absorb vibration; and a biasing device connected to the non-resonant cord, the biasing device adapted to provide tension to the non-resonant cord. ## Claims ### Claim 1 A device for isolating a microphone from vibrations, the device comprising: a. a frame adapted to at least partially surround a microphone, the frame comprising a plurality of mounting points; b. a microphone mount adapted to hold a microphone; c. a suspension assembly adapted to connect the frame to the microphone mount, the suspension assembly comprising: i. a cord adapted to be connected to the frame and the microphone mount; ii. an adjustable means for adjustably fastening the cord to one of the plurality of mounting points; and iii. a damper comprising of a biasing device and a vibration absorbent material inserted in the biasing device, the damper connected to the cord and adapted to provide elasticity to the suspension assembly. ### Claim 2 (depends on 1) The device of claim 1, wherein the frame defines a plurality of surfaces, the plurality of surfaces laying on a plane that is different from each other, the plurality of surfaces being adapted to substantially surround the microphone mount. ### Claim 3 (depends on 1) The device of claim 1, wherein the microphone mount comprises: a. a microphone collar adapted to grip the microphone; and b. a microphone collar insert adapted to be positioned in between the microphone collar and the microphone, the microphone collar insert comprising a vibration absorbent material. ### Claim 4 (depends on 1) The device of claim 1, wherein the microphone mount comprises a. microphone collar adapted to grip the microphone, the microphone collar comprising: a. overlapping portions adapted to move towards and away from each other; and b. an adjustment means for moving the overlapping portions, wherein moving the overlapping portions towards each other tightens the grip on the microphone and moving the overlapping portions away from each other loosens the grip on the microphone. ### Claim 5 (depends on 1) The device of claim 1, further comprising a hanging means for hanging the cord to the microphone mount, wherein at least one end of the cord is adapted to be connected to one of the mounting points and a portion of the non-elastic cord is attached to the hanging means. ### Claim 6 (depends on 1) The device of claim 1, wherein the cord is a non-elastic rope. ### Claim 7 A device for isolating a microphone from vibrations, the device comprising: a. a frame comprising a plurality of surfaces, the plurality of surfaces laying on a plane that is different from each other and defining at least one mounting point; b. at least one non-resonant cord attached to the mounting point of the frame, the non-resonant cord adapted to support a microphone and absorb vibration; c. a microphone mount connected to the frame and the non-resonant cord, the microphone mount adapted to hold the microphone, wherein the non-resonant cord forms at least two lines between the frame and the microphone mount; and d. a biasing device positioned in between the two lines. ### Claim 8 (depends on 7) The device of claim 7, further comprising: a. a biasing device connected to the non-resonant cord, the biasing device adapted to provide tension to the non-resonant cord, the biasing device comprising a hollow interior; and b. a vibration dampening material positioned inside the hollow interior of the biasing device. ### Claim 9 (depends on 7) The device of claim 7, further comprising a microphone mount connected to the frame and the non-resonant cord, the microphone mount adapted to hold the microphone. ### Claim 10 (depends on 9) The device of claim 9, wherein the microphone mount comprises a microphone collar adapted to grip the microphone, the microphone collar comprising a vibration absorbing insert adapted to contact the microphone. ### Claim 11 (depends on 7) The device of claim 7, wherein the frame is a unibody frame. ### Claim 12 (depends on 7) The device of claim 7, further comprising a cord adjustment mechanism, the cord adjustment mechanism comprising a clamp adapted to adjustably secure the cord to the mounting point. ### Claim 13 A method of dampening vibrations transmitted to a microphone connected to a microphone stand, the method comprising: c. securing the microphone to a microphone mount; d. providing a cord; e. providing a frame, the frame comprising a plurality of mounting points; f. connecting the cord to the microphone mount and a first mounting point of the frame, the cord forming a first line; g. connecting the cord to the microphone mount and a second mounting point of the frame, the cord forming a second line; and h. attaching a biasing device to the first and the second line, the biasing device adapted to provide tension to the cord. ### Claim 14 (depends on 13) The method of claim 13, wherein the cord is non-resonant. ### Claim 15 (depends on 13) The method of claim 13, wherein the cord is non-elastic. ### Claim 16 (depends on 13) The method of claim 13, further comprising: i. providing a vibration dampening material, j. attaching the vibration dampening material to the biasing device. ### Claim 17 (depends on 13) The method of claim 13, further comprising adjustably securing the cord to the first mounting point. ### Claim 18 (depends on 13) The method of claim 13, further comprising positioning a vibration dampening material in between the microphone and the microphone mount.
