Information handling system camera shutter with audio feedback of position change
A portable information handling system camera module has a single shutter that slides in response to a single shutter mechanism to manage access for a field of view of both a visual camera and an infrared camera by sliding only between first and second positions, the first position aligning an opening of the shutter with a visual camera and a shield visual camera opening, the second position blocking the opening of the shutter and extending an end of the shutter over infrared camera. The shutter actuates with an electromagnet that generates a magnetic field, such as voice coil. The magnetic field is applied to a speaker magnet that causes vibration at a speaker cone to generate an audible sound.
1. An information handling system comprising:
a housing;
a processor disposed in the housing and operable to execute instructions to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
an embedded controller interfaced with the processor and operable to manage operating conditions in the housing; and
a camera module having a camera, a shutter to selectively block and expose the camera field of view, a speaker and a magnet, the magnet positioned to apply a magnetic field proximate the speaker when the shutter blocks the camera field of view to generate an audible sound by interaction of the magnet with a magnet included in the speaker.
2. The information handling system of claim 1 wherein:
the speaker comprises a cone and a speaker magnet; and
the audible sound is generated by the magnetic field pushing the speaker magnet into the cone.
3. The information handling system of claim 2 wherein the cone comprises polypropylene.
4. The information handling system of claim 1 wherein:
the speaker comprises a cone and a speaker magnet; and
the audible sound is generated by the magnetic field pulling the speaker magnet.
5. The information handling system of claim 1 wherein the magnetic field is generated by a permanent magnet that slides relative to the speaker in cooperation with the shutter.
6. The information handling system of claim 1 wherein the magnetic field is generated by an electromagnetic.
7. The information handling system of claim 6 wherein the electromagnet comprises a voice coil having a first portion and a second portion.
8. The information handling system of claim 7 further comprising:
a guide, the shutter slidingly engaged in the guide;
shutter slider coupled to the shutter and the guide;
a shutter magnet coupled to the shutter slider and interacting with the voice coil magnetic field to slide the shutter.
9. The information handling system of claim 8 wherein the speaker is fixed to the shutter slider.
10. A method for an audible indication of a camera shutter movement, the method comprising:
coupling a speaker proximate the camera shutter; and
activating the audible indication of the camera shutter movement by a magnetic field associated with camera shutter movement and applied to the speaker to interact with a magnet included in the speaker.
11. The method of claim 10 further comprising:
actuating an electromagnet to generate the magnetic field to move the camera shutter; and
applying the magnetic field to a magnet of the speaker to generate the audible indication.
12. The method of claim 11 wherein:
the magnetic field pushes the magnet of the speaker into a speaker cone; and
the speaker cone movement from the push of the magnet of the speaker translates to vibration in air within the speaker cone.
13. The method of claim 11 further comprising:
the magnetic field pulls the magnet of the speaker into a speaker cone; and
the speaker cone movement from the pull of the magnet of the speaker translates to vibration in air within the speaker cone.
14. The method of claim 13 wherein the speaker cone comprises polypropylene.
15. The method of claim 10 further comprising:
sliding the shutter relative to a fixed position of the camera to block the camera;
sliding a magnet with the shutter; and
generating the audible sound when the sliding the magnet passes the magnet proximate the speaker, the speaker fixed relative to the camera.
16. The method of claim 10 further comprising:
sliding the shutter relative to a fixed position of the camera to block the camera;
sliding the speaker with the shutter; and
generating the audible sound when the sliding speaker passes the magnet proximate the magnet, the magnet fixed relative to the camera.
17. The method of claim 16 wherein the magnet comprises an electromagnet.
18. A camera module comprising:
a camera having a field of view;
a shutter to selectively block and expose the camera field of view;
a speaker having a speaker cone and a speaker magnet; and
a magnet positioned to apply a magnetic field proximate the speaker when the shutter blocks the camera field of view to generate an audible sound by movement of the speaker magnet at the speaker cone.
19. The camera module of claim 18 wherein the magnet comprises an electromagnet that generates the magnetic field to move the shutter.
20. The camera module of claim 19 wherein the speaker cone comprises polypropylene.
