CN213426473U - Novel coaxial subwoofer - Google Patents

Abstract

The invention relates to a novel coaxial subwoofer, wherein the loudspeaker is designed into a coaxial loudspeaker and is formed by assembling a mid-bass loudspeaker and a high-pitch loudspeaker, so that a single coaxial loudspeaker can work in a pure low-frequency state and a full-frequency state, the switching work requirement of the pure bass mode and the full-frequency mode can be met by the single coaxial loudspeaker without additionally adding the high-pitch loudspeaker, the coaxial subwoofer can be designed to be thinner and smaller, can be conveniently installed and used at the bottom of an automobile seat, increases the shortage of bass of an original automobile, and can also directly use the full-frequency work mode.

Description

Novel coaxial subwoofer

Technical Field

The utility model relates to a novel coaxial-type subwoofer, by the box, power amplifier circuit board assembly, coaxial loudspeaker assembly, parts such as screen panel equipment forms, also can design for passive form, external power amplifier circuit board assembly, coaxial loudspeaker assembly has two independent magnetic circuit sound production systems of woofer and high pitch loudspeaker, high pitch loudspeaker assembly can directly bond to fix on woofer sound basin and voice coil loudspeaker voice coil upper portion, perhaps the snap-on is on woofer T iron center post upper portion, power amplifier circuit board signal input is when pure bass state, high pitch loudspeaker assembly is out of work, signal input is when full frequency state, high pitch loudspeaker and mid bass loudspeaker can independently sound production simultaneously.

Background

Common subwoofer on the existing market mostly only has been furnished with a pure woofer, when power amplifier circuit board converts full frequency mode of operation, need to equip one or two high pitch loudspeaker in addition and just can the complete full frequency signal of processing, the subwoofer shell body will corresponding increase, the corresponding grow of installation volume.

SUMMERY OF THE UTILITY MODEL

The invention designs the loudspeaker of the subwoofer into a coaxial loudspeaker, the coaxial loudspeaker assembly is provided with two independent magnetic circuit sounding systems of a medium and low sound loudspeaker and a high sound loudspeaker, a high sound loudspeaker assembly part can be directly bonded and fixed on the upper parts of a cone and a voice coil of the medium and low sound loudspeaker or directly fixed on the upper part of a T iron center post of the medium and low sound loudspeaker, the high sound loudspeaker assembly does not work when the signal input of a power amplifier circuit board is in a pure bass state, and the high sound loudspeaker and the medium and low sound loudspeaker can simultaneously and independently sound when the signal input is in a full frequency state. Therefore, the volume of the subwoofer assembled by adopting the coaxial type loudspeaker can be designed to be smaller and thinner, the installation is more convenient, and the movement is more convenient.

Drawings

FIG. 1 is a schematic diagram of a novel coaxial subwoofer structure.

The serial number marks and names of each sub-component in the structural schematic diagram of the attached figure 1 are as follows:

1-power amplifier circuit board 2-medium and low sound loudspeaker assembly 3-bass sound box 4-bass sound box 5-high sound loudspeaker assembly

Detailed Description

The implementation content of attached figure 1 is as follows, (1) power amplifier circuit board, design production according to the box cooperation size, the power can be designed for 12V 24V 220V is general, output carries out supporting design according to the power of speaker, single sound channel output, changeable pure bass and full frequency mode use, can support bluetooth or USB flash disk broadcast function, power amplifier circuit board installs in the bottom half, the output line positive pole connects the anodal soldering lug of coaxial speaker, the output line negative pole connects the coaxial speaker negative pole soldering lug. (2) The middle and low sound loudspeaker assembly is designed and installed in a matching way according to the output power requirement of the power amplifier circuit board, is installed on the upper part of the box body, and is fastened on the box body by using screws to penetrate through the frame holes of the middle and low sound loudspeaker assembly. (3) The bass mask is formed by matching and processing according to the shape requirements of the box body and the loudspeaker, the surface of the bass mask is plated with anti-rust paint, and the bass mask is fixed on the upper parts of the box body and the loudspeaker in a glue or buckle mode. (4) The subwoofer box body is made of alloy materials or plastic materials and is processed into a round shape or a square shape. (5) The high pitch loudspeaker assembly is designed and produced by using a light-weighted neodymium iron boron inner magnetic structure and other light materials, is directly adhered and fixed on the upper parts of a cone and a voice coil of the low pitch loudspeaker in the step (2) by glue, or is directly fixed on the upper part of a T-iron center post of the low pitch loudspeaker, the anode of the high pitch loudspeaker assembly is connected with the anode of the signal lead and the cathode of the low pitch loudspeaker in the step (2) through a high-frequency dividing capacitor, and the cathode of the high pitch loudspeaker assembly is directly connected with the cathode of the low pitch loudspeaker in the step (2) through the signal lead.

Claims (2)

1. The utility model provides a novel coaxial-type subwoofer, characterized by is by the box, power amplifier circuit board assembly, the three essential element equipment of coaxial loudspeaker assembly forms, coaxial loudspeaker assembly has two independent magnetic circuit sound production systems of woofer and high pitch loudspeaker, high pitch loudspeaker assembly can direct bonding fix on woofer sound basin and voice coil loudspeaker voice coil upper portion, perhaps the direct fixation is on woofer T iron center post upper portion, power amplifier circuit board signal input is when pure bass state, high pitch loudspeaker assembly is out of work, signal input is when full frequency state, but high pitch loudspeaker and woofer independent sound production simultaneously.

2. The novel coaxial subwoofer according to claim 1, wherein the speaker is designed as a coaxial speaker, and is assembled by two components, namely a mid-bass speaker and a tweeter, so that a single coaxial speaker can work in a pure low frequency state and a full frequency state, and can meet the switching work requirement of the pure low frequency mode and the full frequency mode without additionally adding the tweeter, and the single coaxial speaker is suitable for the matching use requirement of the ultra-thin ultra-small subwoofer.
