Abstract

The invention discloses a system for testing the power of a loudspeaker. The system comprises a computer; a plurality of test groups are connected onto the computer; each test group comprises a loudspeaker to be tested, a power tester and a power amplifier, wherein the power tester is used for detecting the loudspeaker; and the power amplifier is used for driving the loudspeaker. In the system for testing the power of the loudspeaker, a loudspeaker testing instrument is simple in structure; the number of required equipment is small; and the cost is low. The invention further provides a method for testing the power and a low-frequency parameter of the loudspeaker. The method for testing the power of the loudspeaker has the advantages of being simple to operate, accurate in low-frequency parameter measurement, rapid in operation speed and short in operation time.

Description

technical field [0001] The invention belongs to the technical field of electroacoustic detection, and relates to a loudspeaker power test system, and also relates to a test method for loudspeaker power and low-frequency parameters. Background technique [0002] Conducting power and low-frequency parameter experiments on loudspeakers is an essential and important testing link in the process of R&D and production of loudspeaker products for electro-acoustic companies. Especially in recent years, with the development of loudspeakers in pursuit of miniaturization and high power, enterprises have increasingly urgent needs for loudspeaker power experiments. According to the regulations of international and national standards, power experiments must be carried out during the stereotype inspection and routine inspection of electro-acoustic devices such as loudspeakers, microphone speakers, and headphones. The traditional loudspeaker power test system is measured according to the te...
