A dynamic baffle speaker that enhances sound energy

Abstract

This invention proposes a dynamic baffle speaker enclosure for enhancing sound energy, comprising a speaker unit, a speaker mounting plate, a speaker enclosure frame, a dynamic baffle, a suspension system, and a mechanical coupling component. The speaker unit includes a cone, a frame, and a magnetic circuit. The speaker mounting plate has sound-permeable holes, and the speaker unit's frame is fixedly mounted on the mounting plate. The speaker enclosure frame supports the speaker mounting plate. The dynamic baffle is located in front of the speaker unit. The suspension system connects the dynamic baffle to the speaker enclosure frame, allowing the dynamic baffle to vibrate and shift relative to the speaker enclosure frame. The mechanical coupling component connects the edge of the speaker unit's cone to the center area of ​​the dynamic baffle, transmitting the cone's vibration to the dynamic baffle. This invention directly transmits speaker vibration to the dynamic baffle through the mechanical coupling component, combined with the elastic support of the suspension system, significantly enhancing low-frequency sound wave radiation efficiency and solving the problems of insufficient low-frequency energy and poor transient response in traditional speakers.

Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a dynamic baffle speaker. Background Technology

[0002] Traditional baffle speaker systems consist of a sound source, a power amplifier, and speakers, and are widely used in acoustic scenarios such as recording monitoring, HiFi music, and home theaters. Current mainstream baffle structures all use rigid, stationary baffles. Their inherent drawback is that when the speaker diaphragm (cone) pushes air to generate sound waves, the forward and backward sound waves interfere with each other at the baffle edge, causing sound pressure level rate attenuation (i.e., the "acoustic short-circuit effect"). To compensate for low-frequency loss, the industry has been forced to introduce enclosed enclosures or Helmholtz resonant bass reflex chambers. However, the former reduces electroacoustic conversion efficiency by more than 40% due to the air spring effect, while the latter introduces airflow noise and distortion caused by sudden changes in tuning frequency. Although passive radiators exist as alternatives, their air-coupled energy transfer efficiency is still insufficient, and transient response is sluggish. The physical characteristics of stationary baffles cannot simultaneously solve the problems of acoustic short-circuit suppression and efficient low-frequency radiation, becoming a technical bottleneck restricting the improvement of high-fidelity audio performance. Summary of the Invention
