Problems solved by technology

[0006] The impact of the installation of the mid-bass speaker on the box has been neglected for a long time. In the decades of development of speaker production, no one has ever studied the acoustic effect of the way the speaker is installed on the box.

Embodiment Construction

[0040] 1. Full-range speakers

[0041] Online shopping for second-hand car dismantling 4-inch car full-range speaker, remove the small tweeter, bracket and crossover capacitor. Due to lack of mechanical processing equipment, the dome-shaped titanium cones with diameters of 4.6cm and 8cm were removed from the burnt-out professional tweeter, and holes were drilled on the two titanium domes with a diameter of 1mm. The last step is to glue the two titanium ball tops to the vibrating cone of the 4-inch car speaker in sequence.

[0042] 2. The hedging installation of the loudspeaker on the cabinet

[0043] The size of the bookshelf speaker box is 50cm high, 33cm deep and 25cm wide, two 8-inch mid-bass speakers, and a frame diameter of 21cm. Drill the mounting holes for the speakers on the coaxial line between the front and the back of the cabinet, the diameter of the frame is 21cm, and the sinking is 0.5cm, then use a plastic tube with an inner hole diameter of 4cm and a length of...

Abstract

The invention relates to a moving coil electric loudspeaker which is an elastic system composed of a magnetic circuit, a voice coil, a centering support piece, a vibration basin, a suspension edge anda peripheral support, and no single loudspeaker can produce sound in full audio frequency in the prior art. A coaxial full-frequency loudspeaker in the prior art is only a kind of combined loudspeakers, and is formed by coaxially installing and combining a mid-bass loudspeaker, a high-pitch loudspeaker and a frequency division capacitor. The full-frequency loudspeaker is a full-frequency loudspeaker in a real sense, only one loudspeaker is arranged, and the innovation point of the full-frequency loudspeaker is that a full-frequency function is realized through improvement of a vibration basinof a mid-bass loudspeaker. Another aspect of the invention relates to hedging installation of the loudspeaker on the sound box body, and the prior art is not researched in the aspect. According to opposite impact installation, mutual offset generated by the loudspeakers installed back to back is utilized, so that sound dyeing of the box body and sound flow standing waves in the box body are greatly reduced.

Description

technical field [0001] The invention relates to a moving coil electric loudspeaker, which is an elastic system composed of a magnetic circuit, a voice coil, a centering piece, a vibrating basin, a suspension edge and a peripheral support, and is driven by electromagnetic force to vibrate forcibly to produce sound. . In the prior art, the sound range of a single speaker can be divided into mid-bass and treble, and a mid-bass speaker and a tweeter can also be combined to form a full-range speaker. That is, there is no single speaker in the prior art. Only the speaker is capable of full audio sound. [0002] Another item involved in the present invention is the installation of the loudspeaker on the box body of the sound box. There is no research on this technology in the prior art. The present invention points out the best installation of the loudspeaker on the box body and the improvement of the quality of the sound box. Background technique [0003] The audible sound range...
