Description
Technical field
The present invention relates to speaker technology fields, more particularly to a kind of ceramic loudspeaker box.
Background technique
Speaker is a kind of equipment that audio signal can be transformed to sound, and it is a kind of essential in people's life to be increasingly becoming
Electronic product.People are higher and higher to the performance requirement of speaker, at the same also require the shape of speaker can have both diversity and
Artistry.
The material and control circuit of speaker are an important factor for determining sound quality and function, and control circuit typically contains centre
Unit, power module and other function module are managed, most of speaker is usually to be made of wood materials at present, due to wooden
The hardness of material and the limitation for being subject to processing method so that it is difficult to reach speaker theoretical design requirements, thus exists and are difficult to
Inhibit and eliminate " standing sound wave ", is easy to cause the increase for resetting the music low-frequency range distortion factor, while the speaker shape manufactured
Compare it is dull, it is not beautiful enough, however by use ceramics as occurring cavity, the effect that sound and ceramics resonance reach be use it is wooden
What traditional speaker that matter, plastic cement manufacture was unable to reach under condition of similarity, building the sound quality come can be more preferable, while its glaze
Face is smooth, glittering and translucent, soft glossy, gentle as beautiful, a kind of unique artistic beauty for lying hidden and undeveloped abundant texture.
Summary of the invention
In order to overcome the shortcomings of the prior art, the present invention provides a kind of good appearance, occupy little space and sound quality
Better ceramic loudspeaker box.
The technical solution adopted by the present invention to solve the technical problems is: a kind of ceramic loudspeaker box, including cabinet and loudspeaking
Device, the cabinet include the cavity and bottom cover of ball shape, and the bottom cover and loudspeaker are separately mounted to the both ends of cavity, the chamber
Body is ceramic cavity, and the ceramic cavity is separated into upper cavity and cavity of resorption by the horizontal plane of the centre of sphere of the ceramic cavity
Body, the area that the upper cavity projects on vertical plane are greater than the area that lower chamber projects on vertical plane.
Using the above scheme, ceramic cavity is produced according to above-mentioned proportionate relationship, loudspeaker is then fixed on ceramics
In cavity, and ceramic cavity is subjected to lid conjunction by top cover and bottom cover, so that ceramic cavity forms a chamber, controls loudspeaking
Device carries out the broadcasting of music, and ceramic cavity does not have toughness compared to conventional wooden or plastics sound chamber, not will cause the missing of audio,
It is all fine to high, medium and low frequency audio response, the simple and honest heavy, intermediate frequency of low frequency it is melodious it is melodious, high frequency is clear and melodious loud, simultaneously because pottery
Type chamber in porcelain mold is easily worked, and can produce the speaker of different shaping, and appearance is more beautiful.
Preferably, the upper end of the upper cavity is equipped with upper opening, and the lower end of the lower chamber is equipped under shed, by
The circular arc of circular arc vertex to the upper opening of the ceramic cavity inner wall calls circular arc, by the circular arc vertex of the ceramic cavity inner wall
