Abstract

The invention is suitable for the technical field of loudspeakers, and provides a loudspeaker TS parameter measurement method, which is applied to a loudspeaker TS parameter measurement device, and comprises the following steps: when a loudspeaker is horizontally placed, obtaining a reading of a pressure sensor when a telescopic rod of a stepping motor is in contact with a vibrating diaphragm of the loudspeaker, and recording the reading as a first pressure value; after preset pressure is applied to a vibrating diaphragm of the loudspeaker and a current is introduced into the loudspeaker through the power supply, obtaining the current reading of the power supply when the reading of the pressure sensor is equal to a first pressure value, and recording the current reading as a first currentvalue; and determining the force coefficient of the loudspeaker according to the first current value. According to the loudspeaker TS parameter measurement method provided by the invention, part of TSparameters of the loudspeaker can be accurately measured, the measurement process is simple, a vibrating diaphragm of the loudspeaker cannot be damaged, and the usability is high.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, in particular to a method for measuring TS parameters of loudspeakers. Background technique [0002] TS parameters are important parameters of loudspeakers, and accurate measurement of TS parameters is of great significance to the design and development of loudspeakers. [0003] The TS parameters of the loudspeaker include force coefficient, vibration mass and compliance, etc. The methods for measuring the above parameters in the prior art are mainly the added mass method and the closed volume method. Because the added mass method adopts the glue bonding method, it is easy to leave glue marks on the speaker or The vibration structure of the speaker is damaged, and the usability is poor; the closed volume method needs to make a closed box with an equivalent volume similar to that of the speaker, and the measurement steps are cumbersome and the measurement accuracy is low.
