Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0048] like figure 1 As shown, the present invention includes a paper cone speaker 1, and the paper cone speaker 1 includes a vibrating paper cone 1-2 and a pot frame 1-1 with a radiation port, and the front end of the pot frame side wall of the pot frame 1-1 has a There are flanging edges; the rear end of the basin frame 1-1 is connected with a circular magnet 1-3.

[0049] The present invention also includes a front outer casing 7 whose rear end is installed on the outer flange of the basin frame 1-1 and coaxial with the vibrating paper cone 1-2, and a front outer casing 7 coaxial with the front outer casing 7 is provided in the front outer casing 7. The front inner casing 8.

[0050] It also includes at least one intermediate sleeve 12 located between the front outer sleeve 7 and the front inner sleeve 8, and the intermediate sleeve 12 is co...

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 set. A group of circular short tubes used for radiating speaker sound are disposed in front of a mid-bass cone speaker and form a compound channel, which is used to limit sound radiation environment of a vibrator and affects 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 group of circular regions with even sectional area, and the circular-tube acoustic quality element consists of a group of circular channels 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, low-frequency resonant frequency of the speaker can be lowered, and low-frequency radiation efficiency of the speaker can be increased. The inside of the precision circular-tube compound channel is smooth and encloses the speaker in a large range, so that direct 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 and distortion can be decreased.

Description

[0001] [0002] Technical field: [0003] The present invention relates to a loudspeaker system for a composite channel group of forward precision annular tubes, which belongs to the field of electroacoustic technology. [0004] Background technique: [0005] In daily life, people often use loudspeakers to reproduce sound. After the commonly used electric mid-bass paper cone speakers (including bass, mid-bass, mid-range speakers and full-band speakers, hereinafter referred to as speakers) are completed, the resonance frequency ω0 of the resonance system of its low-frequency force is determined, and ω0 determines The lower limit of the frequency of the sound reproduced by this speaker is usually taken as a reference to the speaker installed on the infinite baffle, indicating that the speaker frequency ω 0 and other indicators. In this case, the loudspeaker placed on the infinite baffle directly radiates and transmits sound to the air in the front and back directions, where...
