    摘要: A method for manufacturing an air pulse generating element is provided. First, a thin film layer including a membrane is provided, and then, a plurality of actuators are formed on the thin film layer. After that, a first chamber is formed between the thin film layer and a first plate and followed by patterning the thin film layer to form a plurality of valves, in which the membrane and the valves are formed of the thin film layer. Subsequently, a second chamber is formed between the thin film layer and a second plate, and a plurality of channels are formed in the first plate and the second plate.

    摘要: A sound producing cell includes a membrane and an actuating layer. The membrane includes a first membrane subpart and a second membrane subpart, wherein the first membrane subpart and the second membrane subpart are opposite to each other. The actuating layer is disposed on the first membrane subpart and the second membrane subpart. The first membrane subpart includes a first anchored edge which is fully or partially anchored, and edges of the first membrane subpart other than the first anchored edge are non-anchored. The second membrane subpart includes a second anchored edge which is fully or partially anchored, and edges of the second membrane subpart other than the second anchored edge are non-anchored.

    摘要: A crossover circuit, disposed within a sound producing device including a first sound producing cell driven by a first driving signal and a second sound producing cell driven by a second driving signal, includes a first filter receiving an input signal at an input terminal of the first filter, a first subtraction circuit, and a second filter coupled between the output terminal of the first filter and the second input terminal of the first subtraction circuit. A first input terminal of the first subtraction circuit is coupled to the input terminal of the first filter; a second input terminal of the first subtraction circuit is coupled to an output terminal of the first filter. The crossover circuit produces the first driving signal and the second driving signal according to a first output signal of the first subtraction circuit and a second output signal of the first filter respectively.
