Problems solved by technology

[0005] The present invention aims at the sound box in the prior art in the case of large dynamics, when the low frequency is too deep, the bass is distorted, the middle and high frequency ranges are subjected to serious sound interference, and the paper cone of the speaker is out of round when the low frequency amplitude movement is too large, resulting in the sound of the speaker. Due to technical defects such as increased damage rate, a speaker with enhanced low-frequency dynamic resonance is proposed

Embodiment Construction

[0018] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] see image 3 , a kind of low-frequency dynamic resonance enhanced sound box proposed in this embodiment includes a box body 10 and a main speaker 20, and the main speaker 20 is installed on the box body 10; it also includes a resonator radiator 30, and the resonance The body radiator 30 is installed on the phase-guiding airflow circuit in the box body 10 for resonating with the sound wave airflow emitted by the main speaker 20 to control the low-frequency dynamics and resonance frequency of the main speaker 20 .

[0020] In this embodiment, the main speaker 20 is equivalent to an active seismic source, and the resonator radiator 30 is equivalent to a passive vibrating body. Resonance will damp the sound wave flow from the main speaker 20 , thereby in turn controlling the low-f...

Abstract

The invention relates to a low-frequency dynamic resonance enhancement loudspeaker box comprising a box body, a main loudspeaker and a resonator radiator. The main loudspeaker is mounted on the box body. The resonator radiator is mounted on a guide airflow loop in the box body and used for generating resonance with sound-wave airflow emitted from the main loudspeaker so as to control low-frequency dynamic and resonance frequency of the main loudspeaker. The technical defects of low-sound distortion caused during too low frequency, serious sound interference in high-medium sound frequency bands and the out-of-round loudspeaker paper cones in movement in over-high low-frequency amplitude, resulting in increase of damage rate of the loudspeaker and the like in the prior art can be overcome effectively, the loudspeaker box is low, deep, natural and extended in performance in the low sound region and is particularly suitable for being applied to K-rooms and Hi-rooms.

Description

technical field [0001] The invention relates to the field of sound boxes, in particular to a sound box with enhanced low-frequency dynamic resonance. Background technique [0002] The speaker is the terminal of the entire audio system. Its structure mainly includes a box body and a speaker, and the structure of the speaker mainly includes a paper cone, a basin frame, a centering piece (also known as a spring wave), a voice coil, and a magnetic steel. The speaker can transmit the sound wave energy into the space in the form of sound wave, and the sound wave energy comes from the conversion of electrical signal and electromagnetic energy, and the vibration and movement of the speaker come from the change of sine wave electrical signal. During the positive half wave, the movement of the speaker is to push out the front speaker, and the electric signal moves in the opposite direction during the negative half wave inside the box, so there are positive and negative phases, positiv...
