Abstract
The invention discloses a power amplifier output driving and induction voltage driving compound full-range loudspeaker which comprises a main loudspeaker (1). The main loudspeaker (1) is provided with main voice coils (2) and a magnetic cylinder (3) inside. The power amplifier output driving and induction voltage driving compound full-range loudspeaker is characterized in that: the main voice coils (2) is winded by induction coils (4) which connect with a high-pitched loudspeaker (5) through leads; the high-pitched loudspeaker (5) is provided at an end of the magnetic cylinder (3), and is arranged in a same axis with the main loudspeaker (1). The power amplifier output driving and induction voltage driving compound full-range loudspeaker has the advantages of novel design, simple structure, low production difficulty, accurate sounding positioning and full display of each frequency range timbre.
Description
Technical field
The present invention relates to a kind of loud speaker, especially a kind of electromagnetic induction principle that utilizes, generate with the keynote circle synchronously, with the audio voltage of equivalent frequently and in theory, and utilize this audio voltage high pitch loudspeaker to be driven the compound full frequency speaker of sounding.
Background technology
Conventional loudspeakers is a kind of sound-producing device, all adopts motor principle, by the audio voltage driving sounding of power amplifier output; And the loud speaker of this principle is when going for the full range sound, must the high, medium and low sound of configuration unit, but because these unit can't use under the condition of concurrent coplane, so its electro mechanical parameter distortion is serious, electroacoustic performance is relatively poor; Though the coaxial full frequency speaker of a shared drive source is also arranged now, the audio voltage that all export from power amplifier in its height unit drives source, and necessary adaptive numerous and diverse frequency divider on the market; The adding frequency divider not only can bring the loss on the power in system, and phase place variation, damping are degenerated, and weakens the control of amplifier to loudspeaker; And the specification requirement of the loud speaker of this structure of production and processing is high, and mechanization production difficulty is bigger.Therefore need a kind of New-type loudspeaker that can address the above problem now.
Summary of the invention
The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, to propose a kind of innovative design, and simple in structure, manufacture difficulty is low, and the power amplifier output that accurate positioning takes place and open up each frequency range tone color to the greatest extent drives and induced voltage drives compound full frequency speaker.
Technical solution of the present invention is: a kind of power amplifier output drives with induced voltage and drives compound full frequency speaker, comprise main loudspeaker 1, in main loudspeaker 1, be provided with by keynote circle 2 and magnetic post 3, it is characterized in that: at the described induction coil 4 that is wound with on keynote circle 2, induction coil 4 is connected with high pitch loudspeaker 5 by lead.
Described high pitch loudspeaker 5 is arranged on the end of magnetic post 3, with main loudspeaker 1 coaxial setting.
The present invention compares with prior art, has following advantage:
The loud speaker of this kind of version has increased induction coil on the basis of conventional loudspeakers, and induction coil is not connected with power amplifier and keynote circle, not only reduces the power consumption of power amplifier, and can guarantee that the keynote circle obtains complete full range signal; Also because low middle pitch does not link to each other mutually with the high pitch voice coil loudspeaker voice coil, and high, medium and low sound can be realized level and smooth combination, it is zero that audio frequency is crosstalked, and various tone colors all can satisfactorily be represented.The closed circuit that high pitch induction coil and high pitch voice coil loudspeaker voice coil form also can play the effect of impedance Control ring, prevent low in voice coil loudspeaker voice coil impedance increase along with increasing of frequency, when keeping rated impedance, increased the high-frequency current of induction coil, make high pitch louder thorough, low middle pitch is thick and heavy more full.
The characteristics of its maximum are the centers that high pitch loudspeaker is arranged at low Squawker, this assembly reveals the coaxial loudspeaker characteristic of concurrent, coplane, zero distance, the sense of hearing demand of " some sounding, synchronous transmission " has been satisfied in sound source pronunciation accurate positioning veritably.
Simultaneously because present technique has been save divider network complicated on the power amplifier output circuit, fundamentally stopped because of insert power loss, phase place variation that frequency divider brings, damping degenerates and weaken the various disadvantages such as control of amplifier to loudspeaker.Adopt present technique can realize that the high-fidelity full range listens to.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1: a kind of power amplifier output drives with induced voltage and drives compound full frequency speaker, comprise main loudspeaker 1, in main loudspeaker 1, be provided with keynote circle 2 and magnetic post 3, it is characterized in that: at the described induction coil 4 that on keynote circle 2, is wound with, be provided with high pitch loudspeaker 5 at main loudspeaker 1 center, be connected by lead between high pitch loudspeaker 5 and the induction coil 4; And this high pitch loudspeaker 5 is arranged on the end of magnetic post 3, forms the coaxial combination with main loudspeaker 1.
The power amplifier output driving of the embodiment of the invention is as follows with the course of work that induced voltage drives compound full frequency speaker: after keynote circle 2 adds audio voltage, under the effect of magnetic circuit system, vibrate, make main loudspeaker 1(hang down Squawker) sounding, and keynote circle 2 drives induction coil 4 and does in the magnetic gap of main loudspeaker 1 and be synchronized with the movement in vibration, induction coil 4 cutting magnetic lines produce and keynote circle 2 frequency together in the motion, the audio voltage of equivalent synchronously and in theory, this audio voltage is transferred to high pitch loudspeaker 5 by lead, and drive high pitch loudspeaker 5 and the low Squawker of main loudspeaker 1() sounding synchronously, reach the purpose of full range sounding; Main loudspeaker 1(hangs down Squawker) be not connected mutually with high pitch loudspeaker 5, do not use frequency divider, obtain the full range audio voltage of equivalent simultaneously, make full use of and show that main loudspeaker 1(hangs down Squawker) the low clear and melodious loud physics speciality of the thick and heavy and high Squawker 5 high middle pitches of middle pitch, merge sounding, thereby obtain ultimate attainment full range audio.
Loud speaker that we can say this structure is the brand-new revolution that full frequency speaker and audio amplifier design and produce.
