Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0057] like figure 1 As shown, the present invention includes a cone speaker 1, which includes a cone frame 1-1 with a radiation port and a vibrating cone 1-2 installed on the chassis of the frame frame 1-1. The rear end of the pot frame 1-1 is equipped with a circular magnet 1-3 connected to the upper and lower magnetic guide plates.

[0058] The present invention also includes the second inner casing 2 that the front end is installed on the outer circumference of the circular magnet 1-3 and is coaxial with the circular magnet 1-3, and the present invention also includes an outer sleeve coaxial with the second inner casing 2 The pipe 3 and the radiation port of the basin frame are located inside the outer casing 3 . An annular tube passage 4 is formed between the outer wall of the second inner sleeve 2 and the inner wall of the outer sleeve 3 ...

Abstract

The invention discloses a high-property mid-bass speaker system and particularly relates to a precise ring-shaped tube composite channel speaker system. A ring-shaped short tube used for radiating sound of a speaker is arranged on the back of a mid-bass cone speaker to form a composite channel, a sound radiation environment of a vibration body is limited, and vibration radiation is influenced. When the speaker works in low frequency, the precise ring-shaped composite channel is formed by a ring-shaped tube acoustic transformator which is provided with an even section and formed by a ring-shaped area, and a ring-shaped tube acoustic quality component which is provided with an even section, is constant and is formed by a ring-shaped channel. Total equivalent vibration quality of the speaker is added due to the combined action of the acoustic transformator and the acoustic quality component, low-frequency resonant frequency of the speaker can be reduced, and low-frequency radiation efficiency of the speaker can be improved. The inner portion of the precise ring-shaped tube composite channel is smooth and clean, the speaker is surrounded in a large range, direct interference, caused by vibration of air inside a box body, of the surface of a vibration body is reduced, load of the surface of the vibration body is even, dynamic response speed is beneficially improved, and distortion is reduced.

Description

[0001] Technical field: [0002] The invention relates to a precision annular tube composite channel loudspeaker system, 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 represents the total equivalent mas...
