Embodiment Construction

[0033] The present invention provides a speaker amplifier in which various signals related to the input and output of the amplifier are analyzed, so that the characteristics and / or diagnosis of the speaker driven by the amplifier can be obtained. These characteristics and / or diagnostics are then presented as output so that different circuits can use this information for audio signal processing.

[0034] In this way, information about speaker performance related to the audio processing module is provided, so that considerable research effort is not required to be spent on the representation characteristics of the speaker model. In fact, once the speaker diagnostic information such as those provided by the device of the present invention is available, traditional signal processing modules and control mechanisms (dynamic range compression, PID controllers, etc.) can be implemented without knowing how to obtain these. Of diagnostic information.

[0035] The present invention allows th...

Abstract

A speaker driver circuit for determining characteristics and / or diagnostic information of a speaker. The speaker amplifier drive circuit performs analysis of various signals related to the input and output of the amplifier so that characteristic and / or diagnostic information of the speaker driven by the amplifier can be derived. These characteristic and / diagnostic information are then presented as output so that different circuits can use the information for audio signal processing.

Description

Technical field [0001] The invention relates to an apparatus and method for determining speaker characteristics and / or diagnostic information. Background technique [0002] It is well known that the output of the speaker should be controlled in such a manner that the output of the speaker cannot be simply driven by any input signal. For example, the signal should be controlled to prevent speaker failure. Two important causes of speaker failure are mechanical defects and thermal defects. [0003] A mechanical defect occurs when the displacement of the speaker diaphragm exceeds a specific limit usually provided by the manufacturer. [0004] Thermal defects occur when there is too much heat dissipation in the speaker. Exceeding the displacement and / or thermal limits can immediately damage the loudspeaker, or can significantly reduce its life expectancy. [0005] There are several ways to limit the displacement of the loudspeaker diaphragm to prevent this failure, for example, by proce...
