Abstract
The utility model relates to a sound box frequency divider, particularly a three frequency division sound box frequency divider, which is composed of a high frequency dividing circuit, an intermediate frequency dividing circuit and a low frequency dividing circuit which comprises an electric inductor L3 connected to a low frequency input line in series and a capacitor C3 connected to an output end in parallel, and the intermediate frequency dividing circuit comprises a capacitor C2 and an electric inductor L2 which are connected to an intermediate frequency input line in series; the electric inductance of the intermediate frequency coil L2 is 1/2-1/8 of that of the low frequency coil L3, and the intermediate frequency electric inductance coil L2 is formed by coiling an enameled wire of which the diameter is 0.30 mm-0.60 mm. The utility model has the positive effects that the sound and the musical instrument generated by the intermediate frequency all have the original sound feel and the clear sound quality, the low frequency has enough electric current so as to generate the firm and powerful sound, and the high frequency generates the clear and active high frequency sound quality.
Description
Technical field:
The utility model relates to a kind of loudspeaker enclosure divider, especially a kind of three frequency division loudspeaker enclosure divider.
Background technology:
In sound system, loud speaker is a terminal performance part, thereby is undertaking important effect.But if the frequency divider processing is bad, also can cause phase distortion, sound is smudgy etc.Voice taper in varying degrees, smudgy, phenomenon such as primary sound not all appear in the present three frequency division audio amplifier on the market in the playback song or when singing card OK.
Summary of the invention:
The purpose of this utility model is to overcome the problem that electric capacity and noninductive resistance occur of having connected in the intermediate frequency frequency dividing circuit of the above frequency divider, provide a kind of high, intermediate frequency is bright and clear, active, the solid strong three frequency division loudspeaker enclosure divider of low frequency.
The utility model is made of high frequency frequency dividing circuit, intermediate frequency frequency dividing circuit and low frequency frequency dividing circuit, and the high frequency frequency dividing circuit comprises capacitor C 1 that is series on the high frequency incoming line and the inductance L 1 that is connected to output; The low frequency frequency dividing circuit comprises inductance L 3 that is series on the low frequency incoming line and the capacitor C 3 that is connected to output; It is characterized by: the intermediate frequency frequency dividing circuit comprises capacitor C 2 and the inductance L 2 that is series on the intermediate frequency incoming line.
The utility model, the inductance value of described intermediate frequency inductance coil L2 are 1/2～1/8 of low frequency inductance coil L3.
The utility model, described intermediate frequency inductance coil L2 directly are that the enamelled wire coiling of 0.30mm～0.60mm forms by line.
The utility model, the enamelled wire that mainly is intermediate frequency network coil L2 selects for use diameter at 0.30mm to 0.60mm, size according to Squawker power is arranged in pairs or groups, handle with the high and low Association of Musicians and transfer, also needn't series resistance, make the intermediate frequency network need not waste too big electric energy, reduce phase distortion, reduce production cost.
The utility model has following good effect:
(1) voice and the musical instrument that send of intermediate frequency all has former phonoreception, and tonequality is clearly arranged.
(2) low frequency has enough electric currents, makes low frequency send solid strong sound.
(3) make high frequency produce bright and clear, active high frequency tonequality.
Description of drawings:
Fig. 1 is the electrical schematic diagram of the utility model embodiment.
Among the figure, T is a high pitch loudspeaker, and M is that Squawker, W are woofer.
Embodiment:
With reference to Fig. 1, this three frequency division loudspeaker enclosure divider, constitute by high frequency frequency dividing circuit, intermediate frequency frequency dividing circuit and low frequency frequency dividing circuit, the high frequency frequency dividing circuit comprises the capacitor C that is series on the high frequency incoming line 1 and is connected to the inductance L 1 of output, and on the incoming line of inductance L 1 and high pitch loudspeaker T series capacitance C; The intermediate frequency frequency dividing circuit comprises capacitor C 2 and the inductance L 2 that is series on the intermediate frequency incoming line; The low frequency frequency dividing circuit comprises inductance L 3 that is series on the low frequency incoming line and the capacitor C 3 that is connected to output.The inductance of intermediate frequency coil L2 is 0.3mH, and the inductance of low-frequency coil L3 is 1.5mH.Intermediate frequency inductance coil L2 directly is that the enamelled wire coiling of 0.35mm forms by line.
Claims (3)
1, a kind of three frequency division loudspeaker enclosure divider, constitute by high frequency frequency dividing circuit, intermediate frequency frequency dividing circuit and low frequency frequency dividing circuit, the high frequency frequency dividing circuit comprises capacitor C 1 that is series on the high frequency incoming line and the inductance L 1 that is connected to output, the low frequency frequency dividing circuit comprises inductance L 3 that is series on the low frequency incoming line and the capacitor C 3 that is connected to output, the intermediate frequency frequency dividing circuit comprises the capacitor C 2 that is series on the intermediate frequency incoming line, it is characterized by: tandem electric inductance L2 on the intermediate frequency frequency dividing circuit, inductance L 2 is between capacitor C 2 and mid frequency ludspeaker M.
