Abstract

A device for insertion into an ear canal of a mammalian subject including a body (2), a first, adjustable acousto-mechanical portion, a second acousto-mechanical portion and an adjustment arrangement (8, 16). At least one sound path (52) extending through the body. The first, adjustable acousto-mechanical portion includes an adjustable channel (4) forming at least part of the sound path and the second acousto-mechanical portion includes a membrane (26). The second, adjustable acousto-mechanical portion is arranged acoustically in series with the first adjustable acousto-mechanical portion. The adjustment arrangement is arranged to adjust the first, adjustable acousto-mechanical portion to alter an acoustic response of the at least one sound path.

Claims (20)

Claims
1. A device, for insertion into an ear canal of a mammalian subject, comprising: a body, having at least one sound path extending therethrough; a first, adjustable acousto-mechanical portion comprising an adjustable channel forming at least part of the sound path; a second acousto-mechanical portion, arranged acoustically in series with the first adjustable acousto-mechanical portion, comprising a membrane; and an adjustment arrangement for adjusting the first, adjustable acousto- mechanical portion to alter an acoustic response of the at least one sound path.
2. The device as claimed in claim 1 , wherein the adjustment arrangement comprises an actuator for adjusting the first adjustable acousto-mechanical portion .
3. The device as claimed in claim 2, wherein the actuator comprises a user operable member arranged to operate at least part of the adjustment arrangement.
4. The device as claimed in claim 3, wherein the user operable member comprises a rotatable knob arranged to adjust the first, adjustable acousto- mechanical portion.
5. The device as claimed in any preceding claim, wherein the channel comprises an adjustable barrier member .
6. The device as claimed in claim 5, wherein the barrier member comprises an adjustable closure.
7. The device as claimed in claimed in claim 5 or 6, wherein the adjustment arrangement enables adjustment of a position of the barrier member.
8. The device as claimed in any one of claims 5 to 7, wherein the barrier member has at least an open position and a closed position.
9. The device as claimed in any preceding claim, wherein the adjustment arrangement is configured to adjust a length and/or width of the adjustable channel.
10. The device as claimed claim 9, wherein the channel is defined by a space between a wall of a cavity within the body and a piston arranged in the cavity, wherein adjustment of the channel is achieved by moving the piston relative to the cavity.
11. The device as claimed in claim 10, wherein the piston is arranged such that it can be held stable in a plurality of different positions in the cavity.
12. The device as claimed in claim 10 or 11 , wherein the cavity and the piston each have a frusto-conical shape such that the adjustable channel has the form of a frusto-conical shell.
13. The device as claimed in any preceding claim, wherein the first, adjustable acousto-mechanical portion can only adopt a plurality of discrete positions.
14. The device as claimed in any preceding claim, wherein the membrane is a separate component attached to the body and the body defines a circumferential rim to which the membrane is attached.
15. The device as claimed in any preceding claim, wherein the membrane comprises at least one corrugation.
16. The device as claimed in claim 15, wherein the corrugation comprises a ridge and/or an indentation.
17. The device as claimed in claim 15 or 16, wherein the corrugation is a spiral.
18. The device as claimed in any preceding claim further comprising a controller arranged to control the adjustment arrangement so as to alter the acoustic response of the at least one sound path.
19. The device as claimed in any preceding claim further comprising a user input arranged to enable a user to control operation of the device.
20. A device for insertion into an ear canal of a mammalian subject, comprising: a body, having at least one sound path extending therethrough; a first, adjustable acousto-mechanical portion comprising a barrier member arranged to alter an acoustic response of the at least one sound path; and a second acousto-mechanical portion, arranged acoustically in series with the first adjustable acousto-mechanical portion, comprising a membrane.
