Problems solved by technology

The defect is mainly due to the inductance of the high frequency network of the frequency divider, the high frequency inductance L 10 Connected in parallel at both ends of the speaker T (such as figure 1 As shown), the purpose is to improve the high-frequency sound, resulting in high-pitched, harsh, harsh, mid- and low-frequency sounds that are gray and indistinct, and the sense of hearing in the entire sound field is gray and unpleasant

Embodiment 1

[0021] Embodiment 1, an induction coil 1 .

[0022] refer to figure 1 , The inductance coil is composed of a core body 1, an enameled wire 2 wound on the surface of the core body and a cover 3. The core body 1 includes two parts: a platform section 12 and a cylinder body 13. The angle a between the slope and the axis of the core body is about 80°. The core body is processed by plastic injection molding and has a hollow structure. First insert the enameled wire 2 into the lead hole 10, the end of which is the lead wire A, and then wind it to the cylinder section 13 in a single layer on the surface of the core body, and the end of the enameled wire is the lead wire B to form the inductance coil L1. in, Picture 1-1 is a schematic diagram of the structure of the cover, Figure 1-2 is a schematic diagram of the structure of the core, Figure 1-3 It is a schematic diagram of the enameled coil winding process, figure 1 It is the schematic diagram of the structure of the inducta...

Embodiment 2

[0023] Embodiment 2, inductance coil 2.

[0024] refer to figure 2 , The inductance coil is composed of a core 1, an enameled wire 2 wound around the core and a cover 3. The core body contains a radial groove 11, and the enameled wire 2 is wound from the bottom of the groove to the core body cylinder 13 to form an inductance coil. The core body is processed by plastic injection molding and has a hollow structure. First insert the enameled wire 2 into the lead hole 10, the end of which is the lead A, and then start winding to the cylinder 13 according to the bottom of the radial groove 11 of the core body, and the end of the enameled wire is the lead B to form the inductance coil L1. in, diagram 2-1 is a schematic diagram of the structure of the cover, Figure 2-2 is a schematic diagram of the structure of the core, Figure 2-3 It is a schematic diagram of the enameled coil winding process, figure 2 It is the schematic diagram of the structure of the inductance coil L1....

Embodiment 3

[0025] Embodiment 3, inductance coil 3.

[0026] refer to image 3 , The inductance coil, compared with embodiment 2, differs in the groove. The grooves in Example 2 are radial grooves, while the grooves in this example are ordinary grooves, that is, the grooves are not perpendicular to the axis of the core. The rest are correspondingly similar to those in Embodiment 2, and will not be described repeatedly. Figure 3-1 is a schematic diagram of the structure of the cover, Figure 3-2 is a schematic diagram of the structure of the core, Figure 3-3 It is a schematic diagram of the enameled coil winding process, image 3 It is the schematic diagram of the structure of the inductance coil L1.

Abstract

The inductance coil is composed of core body and enameled wire coil on the core body. Characters are that the said enameled wire coil includes at least coil with its increased diameters. Lead wire A is end head at smaller diameter, and lead wire B is end head at larger diameter. Applying the disclosed inductance coil to high frequency circuit of frequency divider in three frequency division, and changing traditional parallel connection to series connection obtains satisfied result: pleasing sound, voice in intelligibility, and pleasant tone.

Description

Technical field: [0001] The invention relates to an inductance coil and a frequency divider applied to a three-frequency sound box. Background technique: [0002] In the audio system, the loudspeaker is the terminal performance part, so the frequency divider plays an important role. If the frequency divider is not handled properly, it will cause phase distortion of the sound field and blurred sound. [0003] Most of the three-way speakers on the market are sharp and piercing, the midrange is mixed and indistinct, and the bass is cloudy and weak, with tailing sound and so on. The defect is mainly due to the inductance of the high frequency network of the frequency divider, the high frequency inductance L 10 Connected in parallel at both ends of the speaker T (such as figure 1 As shown), the purpose is to improve the high-frequency sound, which results in high-pitched, harsh treble, and low- and mid-frequency sounds are gray and indistinct, and the sense of hearing in the en...
