Abstract

Speakers in electronic devices, especially communication products, have to be firmly held to the devices' housing to prevent speaker vibration that may cause iaudio distortion. Shown in Figure I is a speaker with a rotational locking bracket for mounting to a housing. Advantageously, such a bracket provides headroom reduction when used for mounting the speaker to the housing. Mounting is enabled using three legs of the bracket to couple to three slots that are recessed into a circumference on the housing.

ROTATIONAL LOCKING BRACKET FOR A SPEAKER

by Chai Wei Seng and Lim Chin Chuan

  Speakers in electronic devices, especially communication products, have to be firmly held to the devices' housing to prevent speaker vibration that may cause iaudio distortion. Shown in Figure I is a speaker with a rotational locking bracket for mounting to a housing. Advantageously, such a bracket provides headroom reduction when used for mounting the speaker to the housing. Mounting is enabled using three legs of the bracket to couple to three slots that are recessed into a circumference on the housing.

  In assembly, the bracket is attached with the speaker and then aligned in a direction shown with Arrow 1 to fit each leg to an associated slot. Upon correctly fitting the legs to their associated slots, the bracket is then rotated in a direction shown with Arrow 2 to lock to speaker to the housing. Clamping with the speaker clamp provides friction and reactive forces that act to hold the speaker securely to the housing. Thus, speaker vibration is substantially and effectively reduced using the bracket when compared to prior methods of clamping the speaker.
