Problems solved by technology

Taking piezoelectric materials as an example, multimorph has the largest output energy, bimorph is next, and unimorph is the smallest; however, the more piezoelectric materials are used, the higher the cost. Higher, the more complicated the assembly
[0006] Furthermore, traditional piezoelectric elements have limited tactile feedback and sound output effects, or cannot adjust the resonance mode arbitrarily; therefore, how to create an innovative structure that can enhance the tactile feedback and sound output effects of the transducer, or It can be used to adjust the resonance mode, which is one of the current important research and development topics, and has also become a goal that the industry needs to improve.

Abstract

Transducers and transducer modules having the transducers are disclosed. An embodiment discloses a transducer that includes a conductive layer having a U-shaped slit toward its swing end. The slit is configured to enhance a haptic feedback or an acoustic propagation, or adjust a resonant mode.

Description

technical field [0001] The invention relates to a transducer, in particular to an energy conversion module using the transducer. Background technique [0002] A transducer is an energy conversion device used to convert one form of energy into another form of energy. Common transducers are motors or generators. The motor converts the input electrical energy into mechanical energy output through electromagnetic induction, and the generator converts the input mechanical energy into electrical energy. [0003] In addition, energy conversion can also be realized using smart materials. When given an external stimulus (stimuli), such as stress, temperature, electricity, magnetic field, pH, humidity, etc., one or more properties of the smart material will change; using this property, the purpose of energy conversion can be achieved. Common smart materials such as piezoelectric material (piezoelectric material), electroactive polymer (Electro-Active Polymer, EAP), shape memory allo...
