Abstract: A rack system includes first and second slide rail assemblies mounted respectively on first and second posts of a rack. The first and second posts define a width therebetween. Each slide rail assembly includes a first rail with a first channel, a second rail displaceable with respect to the first rail, and a third rail movably provided between the first channel of the first rail and the second rail. The first rail of each slide rail assembly has a rail-thickness-wise cross section outside the space in which the width defined by the rack extends, whereas the second and third rails of each slide rail assembly are within the space in which the width defined by the rack extends.

Abstract: A bracket device includes a bracket, at least one mounting member mounted on the bracket, a locking member movable with respect to the bracket, and a fool-proofing member to be located at a first position or a second position with respect to the bracket. When the bracket is at a first mounting angle, the fool-proofing member is located at the first position and is unable to block the locking member from moving with respect to the bracket. When the bracket is flipped from the first mounting angle to a second mounting angle, the fool-proofing member is displaced from the first position to the second position and ends up blocking the moving path of the locking member with respect to the bracket.

Abstract: A slide rail assembly comprises a first rail, a second rail, a third rail, a blocking element and an engagement element. The first rail has a blocking part. The blocking element is connected to the second rail. When the second rail is located at a retrieve position relative to the first rail, and the engagement element is operatively connected to the blocking element for moving the blocking element from a first predetermined position to a second predetermined position relative to the second rail, only the third rail can move relative to the second rail when the slide rail assembly is extended along an extension direction, in order to adjust extension length of the slide rail assembly.

Abstract: A bracket is configured to be mounted to a post of a rack. The bracket includes a side plate, an end plate, a first mounting member and a foolproof device. The end plate is substantially perpendicularly connected to the side plate. The first mounting member is mounted to the end plate. The foolproof device is arranged at a side of the end plate. When the bracket is placed at a first mounting angle relative to the post, the fool proof device does not interfere with the bracket, in order to allow the bracket to be mounted to the post. When the bracket is placed at a second mounting angle relative to the post, the foolproof device interferes with the bracket, in order to prevent the bracket from being mounted to the post.

Abstract: A slide rail assembly includes first and second rails, a retaining member, and a bracket. The second rail is movable to a retracted position relative to the first rail. The retaining member is connected to the second rail. The bracket includes a side plate connected to the first rail, an end plate bent from the side plate, and a movable member movably connected to the side plate. The movable member has at least one retaining portion corresponding to the end plate. When the second rail is in the retracted position, at least a portion of the retaining member faces the movable member so that the second rail can, via the retaining member, restrict displacement of the movable member relative to the retaining member.

Abstract: A method and a portable electronic apparatus for adaptively adjusting a playback effect of speakers are provided. The portable electronic apparatus includes a speaker enclosure volume adjusting device and a processor coupled to the speakers and the speaker enclosure volume adjusting device. In the method, the processor detects a usage demand for the portable electronic apparatus and accordingly determines an audio mode. Based on the determined audio mode, the processor selects and activates multiple speakers, and adjusts an enclosure volume of at least one of the activated speakers, so as to change an audio frequency range of the at least one speaker and an overall audio frequency range covered by the activated speakers. Finally, the processor plays an audio through the activated speakers.

Abstract: A mounting bracket for a slide assembly includes a side wall, an end wall, at least one installation member, a stop, and a resilient member. The end wall is substantially perpendicular to the side wall. The at least one installation member is connected to the end wall. The stop is pivotably connected to the side wall and includes a first portion and a middle portion which is connected to the first portion. The middle portion has a first end portion. The resilient member provides a force to the stop to position the first end portion of the stop to be located corresponding to the end wall.

Abstract: A slide rail assembly to be mounted to a first post and a second post of a rack is provided. The two posts define an accommodation space therebetween. The slide rail assembly is mounted between the first post and the second post by two brackets and includes a transverse width. A portion of the transverse width is arranged within the accommodation space so as to provide more space and thereby facilitate the mounting of an object to the rack.

Abstract: A slide rail assembly includes first and second rails, a retaining member, and a bracket. The second rail is movable to a retracted position relative to the first rail. The retaining member is connected to the second rail. The bracket includes a side plate connected to the first rail, an end plate bent from the side plate, and a movable member movably connected to the side plate. The movable member has at least one retaining portion corresponding to the end plate. When the second rail is in the retracted position, at least a portion of the retaining member faces the movable member so that the second rail can, via the retaining member, restrict displacement of the movable member relative to the retaining member.

Abstract: A slide rail assembly for mounting a lateral side of a chassis to a rack includes first and second rails and a ball assembly. A sidewall of the second rail has a mounting portion to be mounted to a mounting member on the lateral side of the chassis. The ball assembly, movably mounted between the rails to facilitate relative sliding thereof, includes a ball retainer whose lateral portion corresponds in position to the space between a sidewall of the first rail and the sidewall of the second rail. The sidewall of the second rail includes a projecting block for pushing the lateral portion of the ball retainer, keeping the lateral portion close to the sidewall of the first rail.

Abstract: A bracket assembly includes a bracket, an inserting member, an elastic member disposed on the bracket, first and second arms oppositely and pivotally connected to the bracket, and an operation member. The elastic member includes first and second elastic portions correspondingly disposed. The first and second arms each include a first portion having a contact portion abutting against the respective first or second elastic portion and a second portion having a hook portion and a connecting portion oppositely disposed. The operation member is connected between the connecting portions of the first and second arms.
