Vertical full-band ceramic sound box

Abstract

The invention discloses a vertical full-band ceramic sound box. The full-band ceramic sound box comprises a full-frequency loudspeaker with a conical disc, a ceramic shell, a ceramic cone and a support frame, the ceramic shell is mounted at the top of the support frame; the ceramic cone is installed on the supporting frame in the mode that the small outer diameter end faces upwards and the large outer diameter end faces downwards and located below the ceramic shell. The ceramic shell is provided with a mounting cavity and a first cavity for communicating the mounting cavity with the outside; the mounting cavity is positioned at the bottom of the ceramic shell; the ceramic cone is provided with a second cavity penetrating through the upper and lower ends; a through hole communicated with the mounting cavity and the second cavity is formed in the top of the supporting frame, and the full-frequency loudspeaker is mounted in the mounting cavity in the mode that the opening of the conical disc of the full-frequency loudspeaker faces upwards, so that low-frequency sound waves of the full-frequency loudspeaker are diffused towards the first cavity, and medium-high-frequency sound waves ofthe full-frequency loudspeaker are diffused towards the second cavity. The vertical full-band ceramic sound box is high in density, good in rigidity and beautiful in tone.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a vertical full-band ceramic sound box. Background technique [0002] Audio equipment is a kind of equipment that highly reproduces the true nature of music. Audio equipment generally includes a sound source (input, such as a DVD player), a power amplifier (amplifier) ​​and a speaker. The speaker is the terminal of the entire audio system, and its function is to convert audio electrical signals into corresponding It is an extremely important part of the sound system, because it undertakes the key task of converting electrical signals into acoustic signals for human ears to listen directly to. The human sense of hearing is very sensitive, and has a strong ability to identify the timbre of complex sounds. Since the human ear's subjective perception of sound is the most important criterion for evaluating the sound quality of an audio system, it can be considered that the perfor...

Problems solved by technology

[0007] At present, since the cabinet is generally made of wood or plastic materials, when this kind of cabinet is made into a speaker, due to the low density, strength and rigidity, on the one hand, the speaker will elastically deform the cabinet when the speaker vibrates. Resonance is generated, which distorts the music playback, and its timbre is relatively deep; on the other hand, when the speaker vibrates, the speaker cabinet vibrates and the sound emitted by the speaker is transmitted. There is a time difference Δt, Due to the influence of density and rigidity, Δt is larger, which also causes distortion
