**Star News, according to the data of the enterprise search data, Audiwell (832491) has obtained a new utility model patent authorization, the patent name is "a piezoelectric actuator", and the patent application number is CN2023220664141. The authorization date is February 6, 2024.
Patent abstract: the utility model relates to the technical field of electrical components, discloses a piezoelectric actuator, comprises a substrate and a pad on the substrate, piezoelectric ceramics and adhesive sheets, the pads are fixedly connected with the substrate, the piezoelectric ceramics are positioned at the top of the pads and partially cover the pads, the adhesive pieces are located between the connecting pads and the piezoelectric ceramics and are used for connecting the two, the ceramic positive electrode of piezoelectric ceramics is connected to the positive electrode disc of the pad, and the ceramic negative electrode of piezoelectric ceramics is connected to the negative electrode disc of the pad. Compared with the existing technology, the piezoelectric actuator simplifies the structural design, no longer uses conductive adhesive to connect the piezoelectric ceramic and the pad, and optimizes the construction process.
Since the beginning of this year, Audiwell has obtained 6 new patents, an increase of 500% over the same period last year. Combined with the company's 2023 interim financial data, the company invested 1885 in research and development in the first half of 2023510,000 yuan, an increase of 36 year-on-year36%。
