Abstract

Aspects of the disclosure pertain to a system and method for providing temperature limiting for a voice coil of a speaker. The system and method provide the aforementioned temperature limiting based upon monitoring (e.g., measurement) of an amplifier output signal provided to the speaker. Providing the aforementioned temperature limiting promotes improved protection for the speaker.

Description

technical field [0001] The present application relates to the direct measurement of the input signal of a loudspeaker to determine and limit the temperature of the voice coil of the loudspeaker. Background technique [0002] Speakers can be damaged and / or suffer from performance problems when the power of the input signal applied to the speaker exceeds the power handling capability of the speaker. Contents of the invention [0003] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key and / or essential features of the claimed subject matter. Furthermore, this Summary is not intended to limit the scope of the claimed subject matter in any way. [0004] The aspects of the present invention relate to a system and method for providing temperature limitation for a voice coil of a loudspeaker. The systems and methods provide the aforementioned...
