Abstract: An amlodipine dry suspension, comprising a diluent, a suspending aid, etc. and being free of surfactants. A preparation method therefor comprises the following steps: a) preparing an aqueous mixture 1 containing amlodipine besylate by using a high-speed homogenization method; b) adding sodium benzoate to the mixture 1, and homogenizing same at a high speed to obtain a mixture 2; and c) granulating the mixture 2 and other components, and then drying same. The raw materials are homogenized and mixed at a high speed, no surfactant is added during the preparation, amlodipine is fully wetted by using a high-speed homogenization process, prescription components are simplified, and the amlodipine dry suspension is more suitable for children to use. Compared with ultrasonic stirring, scaled-up and industrial production are easier to realize for the high-speed homogenization process, and at the same time, the preparation is good in stability and convenient to carry.

Abstract: A speaker includes a frame, a magnetic circuit and a deflectable diaphragm. The frame supports the magnetic circuit and the deflectable diaphragm. The magnetic circuit includes a yoke, permanent magnet, top plate and a voice coil former. The voice coil former includes a voice coil wrapped around a lower portion of the perimeter. In an embodiment, an inner wall of T-Yoke forms a through hole along the height of the T-Yoke. A lead wire fixture is positioned at least partially within the through hole. The lead wire fixture includes a cable that is spliced or stripped into one or more lead wires that electrically couples with the voice coil. In an embodiment, the cable, the lead wire fixture, and the lead wires are pre-assembled or integrated into a component. This integration helps to reduce the height and width of the speaker and helps to create a more compact speaker.
