Embodiment Construction

[0095] The present invention provides a small speaker system with excellent bass reproduction ability. To this end, a driver is provided on the front surface of the inner box, and a passive radiator is provided on the inner box. Here, according to the present invention, an outer box is provided on the front surface of the passive radiator and forms a certain space with the passive radiator to cover the source radiator. The outer box covers the passive radiator, and a bass radiation port is formed on the front surface of the inner box, so as to guide the sound waves radiated from the passive radiator to be output toward the front surface of the speaker system.

[0096] As a result, the passive radiator is covered by the outer box, so that the aesthetics of the speaker system is improved, and the bass output performance of the speaker system is also excellent, so excellent bass reproduction performance can also be exerted in a small speaker system.

[0097] Furthermore, when the spe...

Abstract

The present invention relates to low sound reproduction of a compact speaker, a degree of freedom of design for the low sound reproduction, chattering noise of structures of electronic apparatuses due to powerful low sound reproduction, chattering noise of structures near a car speaker due to powerful low sound reproduction, leakage of sound out of a vehicle, and an exterior design of unattractive passive radiators. Specifically, a bottom-raised box part is installed in an enclosure to adjust a volume of the enclosure. A plurality of pairs of passive radiators having different resonance conditions is installed. An external enclosure is installed in the outside of the speaker system including a driver, passive radiators and an enclosure. Signal processing is performed to {suppress a gain at a resonance point of the lowest frequency band providing the maximal vibration of the driver} and {emphasize a gain at a resonance point of the lowest frequency band providing the minimal vibration of the driver}.

Description

[0001] Definition of terms [0002] In the description and claims of the present invention, expressions within {} have priority over expressions outside {}. The words defined in the claims also apply to the description. [0003] Vibration analysis of acoustic vibration system composed of {driver, passive radiator, enclosure structure and air}. {{Driver design specification, passive radiator design specification, enclosure design specification} influence of performance on {the vibration mode of the resonance point of the speaker system}} {theory and trial production experience} the appearance design of the speaker. Technical field [0004] The present invention relates to a speaker system and a sound reproduction device. In more detail, first, the present invention relates to a technique for improving the bass reproduction performance of small speaker systems or small audio products; second, the present invention relates to avoiding occurrence of bass reproduction due to vibration o...
