Problems solved by technology

When this new type of speaker is in use, the lower cavity and the placement surface of the speaker form an echo cavity, and the sound waves emitted by the woofer are reflected in the echo cavity for many times and then spread out, which greatly enhances the bass effect. This structure effectively solves the problem of small The problem of poor bass effect of speakers

Embodiment

[0014] Example: such as figure 1 , figure 2 As shown, the present invention is a novel sound box, comprising a casing, a power amplifier, an electronic frequency divider, a woofer 5 and two full-band speakers 6, and the casing includes an upper cavity 1 and a lower cavity 8, The inner side of the lower cavity is a domed surface, and a bass through hole communicating with the upper cavity is arranged on the top of the domed surface. The bass through hole is adapted to the woofer 5 described above. The upper cavity is provided with a woofer, a full-band speaker, a power amplifier and an electronic frequency divider, and the power amplifier is connected to the audio signal interface 7, and the pronunciation cone of the woofer passes downward through the The bass through hole faces the lower cavity, and the lower cavity is an open structure at the bottom, and the lower part is provided with a plurality of gaps 3, between the gaps are shell legs 2, and damping pads 4 are arrange...

Abstract

The invention relates to a novel sound box, which comprises a casing, a power amplifier, an electronic frequency demultiplier, a low-sound horn and a full-frequency band horn, wherein the casing comprises an upper cavity and a lower cavity; a low-sound through hole adaptive with the low-sound horn is formed between the upper cavity and the lower cavity; an box body is internally provided with thelow-sound horn, the full-frequency band horn, the power amplifier and the electronic frequency demultiplier; the power amplifier is connected with an audio signal interface; a sounding paper basin ofthe low-sound horn places downwards and faces to the lower cavity through the low-sound through hole; the lower cavity is in a structure with an open lower part; the lower part of the lower cavity isprovided with a plurality of gaps; and casing supporting legs are arranged among the gaps. When the novel sound box is in use, the lower cavity and a placing surface of the sound box form an echo cavity; and sound wave emitted by the low-sound horn is reflected in the echo cavity for multiple times and is then transmitted, so that the low sound effect can be greatly enhanced.

Description

technical field [0001] The invention relates to an audio device, in particular to a sound box. Background technique [0002] Speaker is a very common electrical appliance. In order to improve its sound effect, it often needs to be used in conjunction with a full-range speaker and a woofer. The so-called full-band speaker refers to a speaker that can cover low frequency, intermediate frequency and high frequency range. The lower limit frequency of full-band speakers is generally 30Hz-60Hz, and the upper limit frequency is 15KHz-20KHz. In general small and medium-sized audio systems, only one or two pairs of full-band speakers can fully undertake the playback task. The woofer is generally a special speaker used to supplement the low-frequency playback of the full-band speaker. This type of speaker is used to enhance the strength and shock of low-frequency playback. When in use, most of the low-frequency signals are sent to a dedicated bass power amplifier after being divid...
