Abstract

A portable electronic device having several features is disclosed. The device can include a retention member that retains flexible circuits extending from a top portion to a bottom portion of the device, thereby allowing some components to be moved from a top portion of the device to a bottom portion. The device may include a cover plate can be secured with a display in the top portion to cover the retention member and other internal components. The device can include an omni-directional port designed to receive a connector different orientations and provide power to the device. The device can include a flexible keyboard having butterfly keycaps. The device can include an array of openings for an audio driver, with some of the array including through holes and blind holes. The device can also include a touch pad having a force feedback sensor and a haptic device.

First claim

What is claimed is:

1. A portable computing system, comprising:
a lid portion, comprising a display assembly;
a top case pivotally coupled with the lid portion and comprising:
sidewalls that enclose and define a cavity and edges of the sidewalls that define a keyboard opening leading into the cavity, and
a data port comprising:
a receptacle region defined entirely by one of the sidewalls and having a size and shape configured to receive an electrical connector arranged to pass power and data to and from the portable computing system,
a through hole defined by the sidewall and connecting the cavity to the receptacle region, and
a printed circuit board (PCB) disposed within the cavity and comprising an edge connector protruding from one side of the PCB, the edge connector extending into the receptacle region by way of the through hole;

a keyboard assembly disposed at least partially within the cavity, the keyboard assembly having a lateral dimension greater than a lateral dimension of the keyboard opening; and
a touch-sensitive user interface assembly comprising an actuator that provides vibratory feedback at the touch-sensitive user interface assembly, and a force sensor arranged to detect an amount of force applied to the touch-sensitive user interface assembly.

2. The portable computing system of claim 1 , wherein the keyboard assembly comprises a key mechanism, comprising:
a keycap that includes a transparent material;
a hinge coupled with the keycap via a first keycap assembly pin and a second keycap assembly pin, the hinge including a first wing that pivots about a first pivot pin, the hinge further including and a second wing that pivots about a second pivot pin; and
a light guide panel disposed below the keycap, the light guide panel directing light from a light source to the transparent material of the keycap.

3. The portable computing system of claim 2 , wherein the key mechanism further comprises:
a switch housing disposed under the keycap, the switch housing having a recess, wherein the light source is disposed within the recess.

4. The portable computing system of claim 1 , further comprising a flexible connector electrically coupled with the data port, the flexible connector further electrically coupled with:
a first integrated circuit coupled with the top case, and
a second integrated circuit coupled with a bottom case, wherein the flexible connector allows the bottom case to rotate with respect to the top case during an assembly operation.

5. The portable computing system of claim 1 , further comprising:
a flexible circuit, comprising a polymeric film with a plurality of electrical traces printed thereon that electrically couples the display assembly to display circuitry coupled with the top case.

6. The portable computing system of claim 5 , further comprising:
a chin cover coupled with the lid portion proximate a region of the lid portion pivotally coupled with the top case and covering a portion of the flexible circuit extending from the display assembly.

7. The portable computing system of claim 6 , wherein the chin cover comprises:
a substrate;
a first layer disposed on the substrate, the first layer having a void region;
a second layer disposed on the void region; and
a third layer disposed on the first layer and the second layer, wherein the chin cover allows transmission of electromagnetic waves to and from internal components covered by the chin cover.

8. A portable computing system, comprising:
a lid portion comprising a display assembly; and
a base portion pivotally coupled with the lid portion, the base portion comprising:
a top case defining a speaker grill comprising a number of speaker holes that include a combination of blind holes extending partially through a wall of the top case and through holes extending entirely through the wall of the top case, the through holes being positioned proximate speakers disposed within an interior volume defined by the base portion, and
a bottom case coupled with the top case to define the interior volume, the bottom case comprising:
an interior facing surface comprising a first terraced region having a first thickness and a second terraced region having a second thickness, the second thickness being greater than the first thickness,
an exterior facing cosmetic surface defining a number of recesses, and
a device foot disposed within each of the recesses defined by the exterior facing cosmetic surface.

9. The portable computing system of claim 8 , further comprising:
a keyboard assembly comprising a keycap;
a switch housing coupled with the keycap, the switch housing having a recess and a light source within the recess; and
a light guide panel positioned between the keycap and the switch housing, wherein the light guide panel directs light from the light source to the keycap.

10. The portable computing system of claim 8 , the base portion further comprising:
a sensor;
a first metallic structure surrounding the sensor; and
a second metallic structure, wherein the first metallic structure and the second metallic structure combine to form a magnetic shield for the sensor.

11. The portable computing system of claim 10 , wherein the lid portion further comprises a magnet, wherein the sensor is a magnetic sensor, and wherein the magnetic shield allows the magnetic sensor to detect the magnet when the lid portion is proximate to the base portion.

12. The portable computing system of claim 8 , further comprising a data port that i) provides transmission of i) data from an external source to an internal component disposed in the base portion, and ii) electrical power to a battery disposed in the base portion.

13. The portable computing system of claim 8 , further comprising a flexible circuit assembly extending from the base portion to a lid portion pivotally coupled with the base portion.

14. The portable computing system of claim 13 , further comprising a retention member secured with the flexible circuit assembly in the lid portion, the retention member comprising a first hook feature and a second hook feature, the first hook feature and the second hook feature securing the retention member with the lid portion.

15. A portable computing system, comprising:
a base portion, comprising:
a keyboard assembly disposed within the base portion and comprising a number of keycaps extending through corresponding openings defined by a top wall of the base portion, each of the keycaps being supported by a low travel support structure and associated with a discrete LED;
a sidewall defining an opening through which a connector of a printed circuit board extends, the connector being configured to receive electrical power and transmit and receive high-speed data transmissions when a plug is engaged within the opening and electrically coupled with the connector; and

a lid portion pivotally coupled with the base portion, the lid portion comprising:
