3 results about "Force factor" patented technology

The compressor shell assembly comprises a compressor shell and a sensor fixing frame, the sensor fixing frame comprises a fixing frame body and a connecting base, the fixing frame body is provided with a containing channel and comprises a top plate and side plates located on the two sides of the top plate, and the side plates are connected between the connecting base and the top plate; the distance between the positions where the side plates on the two sides are connected with the connecting base is L, the diameter of the temperature sensor is D, any point on the inner wall face of the top plate corresponding to the maximum deformation cross section is a point A, the distance between the point A and the center point O of the temperature sensor is OB after insertion, and the distance between the point A and the point O is OA before insertion. For the difference (OB-OA) between the OB and the OA of the same point, the maximum value of the difference corresponding to each point is MAX (OB-OA), and D-L < = MAX (OB-OA) / 3. According to the invention, the influence of uncontrollable force application factors caused by uncontrollable deformation caused by connection of the side plates and the connecting seats is reduced.

Aspects of the subject technology relate to monitoring one or more characteristics of a speaker, such as an excursion, rocking amplitude, or force factor of the speaker. The monitoring may be performed without the use or presence of a sensor that directly measures these speaker characteristics. The monitoring may include determining the excursion, rocking amplitude, or force factor based on an intermodulation distortion that occurs when an ultrasonic tone and one or more human audible tones are output by the speaker concurrently, and / or based on a phase difference between peaks in a speaker current and a speaker voltage.
