Calibration system with clamping system
View Patent ↗Systems and methods are described for clamping a headset in a calibration system using a clamp system that includes a clamp, platform, and one or more spindles (e.g., cushion spindles) to minimize or eliminate issues associated with positioning of headsets. The clamp system comprises a mount having a receptacle. When a device is introduced to the mount the receptacle receives at least a portion of a device. The clamp system includes a clamp attached to the mount and having a first arm rotateably coupled to a second arm that controls the first arm between an open position and a closed position. A platform and at least one spindle are connected to the first arm. When the device is present in the receptacle and the first arm is in the closed position the spindle contacts the device and seats or secures the device in the receptacle.
1. A system comprising: a pipe comprising at least one section that spans between a first end and a second end of the pipe, wherein the pipe has a cylindrical cross-section; a mount comprising a receptacle positioned in the pipe a first distance from the first end and a second distance from the second end, wherein the receptacle receives a device having at least one microphone that is to be calibrated and secures the at least one microphone a third distance inside an inside surface of the pipe; a clamp attached to the mount and comprising a first arm rotateably coupled to a second arm that controls the first arm between an open position and a closed position; a platform and a spindle connected to the first arm, wherein the spindle includes a cushion tip on a distal end, wherein when the device is present in the receptacle and the first arm is in the closed position the cushion tip contacts the device and seats the device in the receptacle; and an adapter connected to the first end that connects a loudspeaker to the pipe, wherein the pipe controls an acoustic energy experienced by the plurality of microphones so that each microphone of the plurality of microphones receives equivalent acoustic energy.
2. The system of claim 1 , wherein the mount comprises a pipe section having a length and an inside diameter, wherein the pipe section has a cylindrical cross-section.
3. The system of claim 2 , wherein when the device is secured in the receptacle at least a portion of the device is positioned a first distance inside the pipe section.
4. The system of claim 1 , wherein the receptacle includes a cutout that positions the device so that a first portion of the device is exposed to a first region adjacent to a first side of the mount and a second portion of the device is exposed to a second region adjacent to a second side of the mount.
5. The system of claim 1 , wherein when the device is present in the receptacle and the first arm is in the closed position an attached position at which the clamp is attached to the mount results in the cushion tip pulling the device back toward a base of the clamp and securing the device in the receptacle.
6. The system of claim 1 , wherein the clamp comprises a third arm rotateably connected to the first arm and to the second arm, wherein movement of the second arm is translated via the third arm to control the first arm between the open position and the closed position.
7. The system of claim 1 , wherein the platform comprises a first surface having a first orifice that accepts the spindle.
8. The system of claim 1 , comprising a calibration pipe and a loudspeaker connected to the mount.
9. The system of claim 8 , wherein the device comprises at least one microphone, wherein the at least one microphone is calibrated while seated in the receptacle.
10. The system of claim 8 , wherein the device comprises a plurality of microphones, wherein the receptacle locates each microphone of the plurality of microphones an equal distance from the loudspeaker and the plurality of microphones are calibrated while seated in the receptacle.
11. The system of claim 1 , wherein the first distance is at least 30 centimeters.
12. The system of claim 1 , wherein the second end is open.
13. The system of claim 1 , wherein the second end is coupled to a cap, wherein the cap closes the second end.
14. The system of claim 1 , wherein the at least one microphone comprises a plurality of microphones, wherein the receptacle locates each microphone of the plurality of microphones an equal distance from the loudspeaker.
15. The system of claim 1 , comprising an absorbing material positioned inside at least a portion of the pipe.
16. The system of claim 1 , wherein the loudspeaker is a mouth simulator loudspeaker.
