  • Patent number: 9402134
    Abstract: A stiffened diaphragm manufacturing method and the manufactured diaphragm using same are provided. The manufacturing method includes the steps of: applying a hot glue layer to a side of a stiffened plate; putting a base layer on the hot glue layer, and then heating and adhering the base layer and the stiffened plate together; and performing a pressing process on the base layer and the stiffened plate to form a diaphragm having a central portion and a surround portion. The stiffened plate is coated uniformly with the hot glue layer and then put on the base layer to undergo heating and adhesion; hence, an oversupply or undersupply of a glue will be unlikely to happen. Furthermore, the manufacturing process is simple and attains high-strength adhesion between the stiffened plate and the base layer.

  • Patent number: 9281110
    Abstract: An external-magnet-type magnetic circuit includes an iron core and at least one composite magnet coaxially mounted around the iron core. The composite magnet has two magnetic poles with field directions thereof substantially perpendicular to each other, wherein one of the magnetic poles has the field direction thereof pointing to the iron core, and a magnetism-guiding plate being deposited on the other magnetic pole of the composite magnet and being separated from the iron core by a magnetic gap. Thereby, the composite magnet provides high magnetic flux density in relatively small volume, without the additional use of any magnetism-guiding yokes, and thus is particularly suitable for small-size amplifiers where it helps to improve acoustic sensitivity and acoustic output performance.
