Samsung patents speaker design that uses a wire loop to cut down noise

Samsung has been granted a patent for an electronic device speaker design that incorporates a flexible board with a wire wrapped around the speaker's coil. This wire is connected to the device's main circuit board to manage electrical current flow. The goal is to reduce unwanted noise generated by the speaker during operation.

Why it mattersThis is a technical improvement to speaker hardware that could lead to cleaner sound in future Samsung devices, though it is a specific engineering detail rather than a new feature.

In the filing’s own words

An electronic device includes: a housing; a first speaker in the housing; and a printed circuit board in the housing and surrounding at least a portion of the first speaker, wherein the first speaker includes: a coil area in which a coil for an operation of the first speaker is disposed; a flexible board on an outer portion of the coil area and including a wire surrounding at least a portion of the coil area; and a connection terminal at one end of the flexible board and electrically connected to the printed circuit board.

What exactly they claim (claim 1)

1. An electronic device comprising: a housing; a first speaker in the housing; and a printed circuit board in the housing and surrounding at least a portion of the first speaker, wherein the first speaker comprises: a coil area in which a coil for an operation of the first speaker is disposed; a flexible board on an outer portion of the coil area and comprising a wire surrounding at least a portion of the coil area; and a connection terminal at one end of the flexible board and electrically connected to the printed circuit board, and wherein the wire is configured such that an offset current supplied from the printed circuit board flows through the wire to reduce noise generated from the first speaker.
