A coupling is configured to hold detachably a speaker on a computer component by a gravitational force acting on the speaker. The coupling may be a pocket on the component and a flange on the speaker. The coupling may include vertically aligned projecting elements on the component and corresponding receptacles on the speaker. The coupling may be hidden after the speaker has been mounted. To attach the speaker it is held near the component and then lowered with respect to the coupling mechanism to reach a position where the speaker is fixed relative to the component by a gravitational force.
