Abstract: A magnetic balance guided linear vibration motor comprising a housing (1, 2), a vibrator, and a stator fixedly connected with the housing. The vibrator comprises a counterweight (31) and a vibrating block embedded and fixed in the counterweight, wherein a pair of first balancing magnets (61a, 61b) are respectively arranged on vertical sidewalls at two ends of the counterweight, second balancing magnets (62a, 62b) corresponding to the first balancing magnets are respectively arranged on the housing at positions corresponding to the two ends of the counterweight, and the second balancing magnets and the corresponding first balancing magnets are attracted to each other. The vibration motor provides the vibrator with vibration balance in a motor vibration space, overcomes the problem of wearing, deformation and balance error and the like due to motor mechanical balance means, and reduces motor noise, thus increasing the product quality and stability of the motor.

Abstract: The present disclosure provides a speaker diaphragm and a speaker. The diaphragm includes two surface layers compounded together and at least one intermediate layer located between the two surface layers, at least one of the surface layers is a thermoplastic polyester elastomer film layer, and at least one of the intermediate layers is an adhesive layer, wherein the thermoplastic polyester elastomer film layer has a Young's module of 1-1000 MPa, a loss factor being greater than or equal to 0.015, and an elastic recovery rate after 10% strain being greater than or equal to 80%. The speaker diaphragm may be made very thin, thus reducing the weight of the speaker diaphragm, improving the space allowance for vibration, improving the sensitivity, and making the F0 of the speaker lower. Further, elastic area of the speaker diaphragm is wider and the resilience performance is excellent.
