Abstract
The utility model discloses a power amplifier output driving and induced voltage driving compound type full frequency loudspeaker, which comprises a main loudspeaker (1). A main voice coil (2) and a magnetic cylinder (3) are arranged in the main loud speaker (1). The power amplifier output driving and induced voltage driving compound type full frequency loudspeaker is characterized in that an induced coil (4) is wound on the main voice coil (2) and connected with a high pitch loudspeaker (5) through a lead. The high pitch loudspeaker (5) is arranged at the end of the magnetic cylinder (3) and is arranged coaxially with the main loudspeaker (1). The power amplifier output driving and induced voltage driving compound type full frequency loudspeaker is innovative in design, simple in structure, low in production difficulty, accurate in sound producing and locating, and gives full play to tone of different frequency ranges.
Description
Technical field
The utility model 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; In system, add frequency divider and not only can bring the loss on the power, phase place variation, damping are degenerated, weaken the control of amplifier 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 utility model 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, takes place that accurate positioning drives with the power amplifier output of opening up each frequency range tone color to the greatest extent and induced voltage drives compound full frequency speaker.
The technical solution of the utility model 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 on keynote circle 2, is wound with, induction coil 4 is connected with high pitch loudspeaker 5 through lead.
Described high pitch loudspeaker 5 is arranged on the end of magnetic post 3, with main loudspeaker 1 coaxial setting.
The utility model is compared 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 with the high pitch voice coil loudspeaker voice coil mutually, 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, made high pitch louder thorough, low middle pitch is thick and heavy more full.
Its maximum characteristic is the centers that high pitch loudspeaker are 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 utility model embodiment.
Embodiment
Below with the embodiment of accompanying drawings the utility model.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, be connected through lead between high pitch loudspeaker 5 and the induction coil 4 at main loudspeaker 1 center; 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 utility model embodiment is following 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 (low Squawker) sounding; And keynote circle 2 drives induction coil 4 and in the magnetic gap of main loudspeaker 1, does and be synchronized with the movement in vibration; Induction coil 4 cutting magnetic lines produce and the keynote circle 2 same audio voltages of equivalent frequently, synchronously and in theory in the motion; This audio voltage is transferred to high pitch loudspeaker 5 through lead, and drives high pitch loudspeaker 5 and the synchronous sounding of main loudspeaker 1 (low Squawker), reaches the purpose of full range sounding; Main loudspeaker 1 (low Squawker) is not connected with high pitch loudspeaker 5 mutually; Do not use frequency divider; Obtain the full range audio voltage of equivalent simultaneously; Make full use of and show the low clear and melodious loud physics speciality of the thick and heavy and high Squawker 5 high middle pitches of middle pitch of main loudspeaker 1 (low Squawker), merge sounding, thereby obtain ultimate attainment full range audio.
Can high pitch loudspeaker 5 be set directly at the end of the magnetic post 3 of main loudspeaker 1, so just realize the structure of the coaxial and concurrent coplane of high pitch loudspeaker 5 and main loudspeaker, this structure has the effect of sound source pronunciation accurate positioning, and acoustics is splendid; High pitch loudspeaker 5 can also be arranged on main loudspeaker 1 outside, is provided with main loudspeaker 1 (low Squawker) split coplane, makes the combined type full-range cabinet.
Loud speaker that we can say this structure is the brand-new revolution that full frequency speaker and audio amplifier design and produce.
