Embodiment Construction

[0021] Combine below Figure 1 to Figure 6 The present invention is described in detail.

[0022] In the existing dome structure, foam material and aluminum foil are combined to prepare the dome structure. Since the foam material and aluminum foil are two different materials, the bonding between layers is not tight, which will also cause separation. layer, resulting in poor waterproof effect and easy water absorption. In addition, different property materials have different sound characteristics, which will also cause the loss of sound performance. When preparing dome structures composed of different materials, the preparation method Also more complicated.

[0023] In order to overcome the problems of fragile dome structure, easy delamination, insufficient strength, poor appearance, large thickness, and poor waterproof effect in the prior art, the present invention provides a dome structure prepared by using carbon fiber materials. The material replaces the existing aluminum...

Abstract

The invention relates to a carbon fiber dome, the carbon fiber dome includes at least two layers of carbon fiber prepregs; wherein, the at least two layers of carbon fiber prepregs include at least two carbon fiber materials. The present invention also relates to a method for manufacturing a carbon fiber dome, comprising the steps of pre-impregnating at least two carbon fiber materials with a pre-impregnating resin; bonding the pre-impregnated at least two carbon fiber materials to each other. In the carbon fiber dome structure in the present invention, by replacing the aluminum foil with carbon fiber prepreg, the strength is improved, and the thickness is reduced at the same time, so that the sound quality is improved. Through the curing process of the prepreg, the carbon fiber material is closely bonded to form The integrated structure avoids the phenomenon of separation between layers, and the waterproof effect is better to ensure the service life.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic instruments, in particular to a carbon fiber dome structure and a method for manufacturing the carbon fiber dome. 【Background technique】 [0002] A dome speaker is a speaker that uses a dome-shaped diaphragm to directly radiate sound waves. It belongs to the electric speaker. The diaphragm is a hemispherical diaphragm. The voice coil is directly supported by the diaphragm ring without a centering piece. It is characterized by good high-frequency response, wide directivity and low distortion. The dome top of the diaphragm is usually made of aluminum foil and foam material. With the development of the electronics industry, electroacoustic systems need to continuously improve performance and reliability, and the requirements for the dome are getting higher and higher. The existing aluminum foil and The domes made of foamed materials can no longer meet the needs of use, and problems such as broken al...
