Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0046] Such as 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. The vibration paper cone 1-2 is coaxial with the circular magnet 1-3.

[0047] Also includes the second inner casing 2 that the front end is installed on the outer circumference of the circular magnet 1-3 and coaxial with the circular magnet 1-3; also includes the outer casing 3 coaxial with the second inner casing 2, the basin The radiation port of the frame 1-1 is located inside the outer sleeve 3; it also includes at least one intermediate sleeve 12 between the outer sleeve 3 ...

Abstract

The invention discloses a high-performance mid-bass loudspeaker system, namely a loudspeaker system with a backward precision annular-tube combined channel set. A set of annular short tubes for radiating sound of a mid-bass cone loudspeaker is mounted upwards behind the loudspeaker to form a combined channel, a sound radiation environment of a vibrator is limited, vibration radiation is influenced, when the loudspeaker operates at low frequency, a precision annular-tube combined channel is composed of an annular-tube acoustic transformer composed of an annular interval even in cross section and an annular-tube acoustic quality element composed of an annular channel even and constant in cross section, total equivalent vibration quality of the loudspeaker is increased by interaction of the acoustic transformer with the acoustic quality element, and low-frequency resonance frequency of the loudspeaker can be lowered. The inside of the channel set is smooth and clean, the loudspeaker is surrounded in a large range, interference of the surface of the vibrator by vibration of air in a box is reduced, surface load of the vibrator is even, dynamic response speed is convenient to increase, distortion is reduced, and medium- and low-frequency radiation efficiency is improved.

Description

[0001] Technical field: [0002] The present invention relates to a loudspeaker system for a composite channel group of backward precision annular tubes, which belongs to the field of electroacoustic technology. Background technique: [0003] 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 ω0=, and MM re...
