Embodiment 1

[0027] like Figure 4-6 As shown, a vibration-balanced TV speaker proposed by the present invention includes an anti-magnetic cover 1 and a fixing ring 3, and a dust-proof mechanism is arranged inside the fixing ring 3;

[0028] The dust-proof mechanism includes a cavity 14 opened inside the fixing ring 3, an air inlet 15 is formed on the side of the fixing ring 3 close to the cavity 14, and an exhaust hole 16 is formed on the side of the fixing ring 3 away from the air inlet 15, A mounting seat 17 is installed on the side of the cavity 14 close to the air inlet 15 , an air bag 18 is installed on the outside of the mounting seat 17 , and two springs 19 are installed on the side of the cavity 14 close to the air bag 18 , and the two springs 19 are far away from the cavity. One end of the inner wall of 14 is jointly mounted with a pressure ring 20, a side of the airbag 18 close to the air inlet hole 15 is fixedly connected with an air intake ring 21, and the side of the airbag 1...

Embodiment 2

[0034] like Figure 1-4 As shown, based on the first embodiment, the outside of the magnetic shield 1 is fixedly connected with a basin frame 2, the fixing ring 3 is fixedly connected to the end of the basin frame 2 away from the magnetic shield 1, and the magnetic shield 1 is installed on the side away from the basin frame 2 There are two terminals 4, the interior of the magnetic shield 1 is fixedly connected with a pole column 5, the cross section of the pole column 5 is arranged in a hollow circular ring, the interior of the magnetic shield 1 is fixedly connected with a permanent magnet 6, and the permanent magnet 6 is located in the pole column 5. The center position of the voice coil 10 is surrounded by copper wires. The vibration of the voice coil 10 will drive the sound cone 8 to vibrate. The folding ring 7 and the sound cone 8 are made of fiber material. The folding ring 7 can move the sound protection cone 8 along the axial direction of the speaker. , the cross-sectio...

Abstract

The invention discloses a television loudspeaker with balanced vibration, which comprises an antimagnetic cover and a fixing ring, and is characterized in that the fixing ring is internally provided with a dustproof mechanism; the dustproof mechanism comprises a cavity formed in the fixing ring, an air inlet hole is formed in the side, close to the cavity, of the fixing ring, an exhaust hole is formed in the side, away from the air inlet hole, of the fixing ring, a mounting base is mounted on the side, close to the air inlet hole, of the cavity, an air bag is mounted outside the mounting base, and two springs are mounted on the side, close to the air bag, of the cavity. The side, close to the air inlet hole, of the air bag is fixedly connected with an air inlet ring, and the side, close to the exhaust hole, of the air bag is fixedly connected with an exhaust ring. When the loudspeaker works, a ventilation wall appears at the port, dust is blocked outside the loudspeaker, the dust is prevented from being accumulated outside the loudspeaker, the tone quality of the loudspeaker is greatly improved, meanwhile, static electricity generated among the dust is prevented from influencing equipment inside the loudspeaker, and the loudspeaker is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of television speakers, in particular to a vibration-balanced television speaker. Background technique [0002] A speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great influence on the sound quality. The speaker is the weakest component in the audio equipment, and it is the most important component for the sound effect. There are many types of speakers, and they vary widely in price. Audio electric energy through electromagnetic, piezoelectric or electrostatic effects, make its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air to produce sound, which is an indispensable part of TV. [0003] When the existing TV speaker is working, the vibration of the voice coil is unbalanced, which will cause sound distortion. At the same time, when the voice coil vibrates, it is prone to disconnection, which affects...
