Abstract: A high bass speaker monomer comprises a framework, a magnetic air loop component and a vibration membrane. The frame work is disposed at a central position of the frame work. A hollow structure is formed on the framework and around the magnetic air loop component. An isolation ring formed on the framework divides the hollow structure into at least one high tone region and bass region respectively located near and far away from the magnetic air loop component. The vibration membrane is disposed on the framework and covers the magnetic air loop component and the two regions. The high bass speaker monomer is disposed in a casing body to construct a high bass earphone structure. The isolation ring separates the high tone from the low tone to prevent them from mixing. Therefore, the sound of the earphone is more stable and the quality of the sound is better.

Abstract: An earphone with dual loudspeakers includes a casing, a retaining member, a tweeter, and a woofer. The casing has a first sound outlet passage and an accommodation space therein. The retaining member is installed in the accommodation space. Two ends of the retaining member are formed with a first accommodation cavity and a second accommodation cavity, respectively. The tweeter and the woofer are respectively installed in the first and second accommodation cavities and then installed in the casing. The tweeter has a sound outlet side facing the first sound outlet passage. A second sound outlet passage is formed between the outer wall of the tweeter and the inner wall of the first accommodation cavity. The second sound outlet passage communicates with the first sound outlet passage. The woofer has a sound outlet side facing the second sound outlet passage.

Abstract: An acoustic metal diaphragm comprises a diaphragm base made of an organic material and a metal-plated layer. The diaphragm base has a smooth surface. The metal-plated layer is adhered to the smooth surface of the diaphragm base by an intermediate layer. The intermediate layer is disposed between the diaphragm base and the metal-plated layer. The metal-plated layer is made of pure beryllium or a beryllium alloy. Accordingly, the diaphragm base is made of the organic material and provided with a smooth surface. The intermediate layer allows the metal-plated layer to be adhered to the smooth surface more firmly. Using the pure beryllium or beryllium alloy to manufacture the metal-plated layer increases the rigidity of the diaphragm base and maintains the softness thereof to slow down the attenuation of the bandwidth, attain a wider frequency band, solve the problem of the high frequency and increase the quality of the sound.
