Embodiment Construction

[0048] The present invention will be further described below in conjunction with the drawings and specific examples.

[0049] Such as figure 1 As shown, the present invention includes a paper cone speaker 1. The paper cone speaker 1 includes a vibrating paper cone 1-2 and a cone frame 1-1 with a radiation opening. The front end of the cone frame side wall of the cone frame 1-1 is There is an outer flange, and a circular magnet 1-3 is installed at the rear end of the basin frame 1-1.

[0050] The present invention also includes a front outer tube 7 with a rear end mounted on the outer flange and coaxial with the vibrating paper cone 1-2. The front outer tube 7 is provided with a front inner tube coaxial with the front outer tube 7 Sleeve 8; the radiant opening of the basin frame is located inside the front outer sleeve 7. The front outer sleeve 8 and the front inner sleeve 7 are fixedly connected to each other through a support frame. An annular tube passage 6 is formed between t...

Abstract

The invention discloses a high-performance mid-bass speaker system and particularly relates to a forward speaker system with a precision circular-tube compound channel. The forward speaker system with the precision circular-tube compound channel is provided with a group of circular short tubes which are used for radiating speaker sound and arranged in front of a mid-bass cone speaker, and the circular short tubes form a compound channel, which is used to limit sound radiation environment of a vibrator and affect vibrational radiation. When the speaker operates at low frequency, the precision circular-tube compound channel is composed of a circular-tube acoustic transformer and a circular-tube acoustic quality element, wherein the circular-tube acoustic transformer consists of a circular region with even sectional area, and the circular-tube acoustic quality element consists of a circular channel with even and constant sectional area. Total equivalent vibrational quality of the speaker is increased under the coaction of the acoustic transformer and the acoustic quality element, and low-frequency resonant frequency of the speaker can be lowered. The inside of the compound channel is smooth and encloses the speaker in a large range, so that vibrational disturbance of air in a box upon the surface of the vibrator is reduced, the surface load of the vibrator is even, dynamic response speed can be increased, distortion can be decreased, medium- and low-frequency radiation efficiency is increased and sound field is changed.

Description

Technical field: [0001] The front -to -precision ring tube composite channel speakers system is the field of the present invention, which belongs to the field of electro -acoustic technology. Background technique: [0002] In daily life, people often use speakers to replace their sounds.Commonly used electric medium -sized medium -sized paper pot speakers (including bass, medium bass, medium sound speakers, and full -frequency belt speakers, here are also referred to as speakers), the resonance frequency of its low -frequency resonance system is determined.The lower limit of this speaker replays the sound frequency, and is usually based on the speakers installed on the unlimited barrier board as the reference, indicating that the speaker frequency Ω 0 Wascable indicators.In this case, the speakers placed on the infinite barrier board directly transmit the sound freely to the air in the two directions in the front and back., Audio Equal Equipment Mass M2, the front of the vibrati...
