Earbud case with hall effect sensor and related holder
Various implementations include earbud cases with a Hall effect sensor configured to aid in detecting whether the case is open or closed. Certain additional implementations include a holder for a Hall effect sensor in an earbud case. In some particular aspects, a case for a set of earbuds includes: a top section including a set of magnets; and a base section movably coupled with the top section, the base section having: an upper compartment including a set of slots for holding the earbuds; and a lower compartment, having: a printed circuit board (PCB); a holder coupled with the PCB; and a Hall effect sensor coupled with holder, wherein the holder separates the Hall effect sensor from the PCB.
1. A case for a set of earbuds, the case comprising:
a top section comprising a set of magnets; and
a base section movably coupled with the top section,
wherein the top section is configured to slide tangentially relative to the base section to open and close the case, such that the top section remains on substantially a same plane as it moves relative to the base section,
wherein the base section comprises:
an upper compartment comprising a set of slots for holding the earbuds; and
a lower compartment, comprising:
a printed circuit board (PCB);
a holder coupled with the PCB;
a Hall effect sensor coupled with holder, wherein the holder separates the Hall effect sensor from the PCB; and
a controller coupled with the Hall effect sensor, wherein the controller is configured to take a prescribed action in response to the Hall effect sensor indicating proximity to a plurality of the set of magnets,
wherein the controller is configured to take the prescribed action in response to the Hall effect sensor indicating proximity to a threshold number of the plurality of the set of magnets.
2. The case of claim 1 , wherein the Hall effect sensor is configured to detect proximity to at least one of the set of magnets.
3. The case of claim 1 , wherein the holder is directly coupled to the PCB, and wherein the Hall effect sensor is directly coupled to the holder.
4. The case of claim 1 , wherein the holder has a slot that is shaped to accommodate the Hall effect sensor in only one orientation.
5. The case of claim 4 , wherein the orientation comprises a vertical orientation.
6. The case of claim 4 , wherein the holder comprises:
a base coupled to the PCB; and
at least one protrusion extending from the base away from the PCB, wherein the at least one protrusion defines the slot that is shaped to accommodate the Hall effect sensor.
7. The case of claim 1 , wherein the holder maintains a distance between the Hall effect sensor and the top section such that the Hall effect sensor is sensitive to a magnetic flux from each of the set of magnets for detecting a change between an open position and a closed position of the top section relative to the base section.
8. The case of claim 1 , wherein the holder maintains a distance between the Hall effect sensor and the top section such that the Hall effect sensor is sensitive to a magnetic flux from each of the set of magnets for detecting a change between an open position and a closed position of the top section relative to the base section as the top section slides tangentially relative to the base section.
9. The case of claim 1 , wherein the threshold number is equal to at least two.
