Abstract
The utility model provides a magnetic circuit suspended type loudspeaker. The magnetic circuit suspended type loudspeaker comprises a suspension edge, a vibrating diaphragm, a loudspeaker coil, a magnetic circuit and a loudspeaker cone frame. Both the loudspeaker coil, positioned under the diaphragm, and the diaphragm are connected with the suspension edge. The loudspeaker coil also falls into a magnetic gap formed by the magnetic circuit. Two sides of the loudspeaker coil are fixedly connected with a main damper. An auxiliary damper which supports the magnetic circuit is laid beneath the bottom surface of magnetic circuit. Two ends of the auxiliary damper are fixed on the loudspeaker cone frame. The magnetic circuit suspended type loudspeaker can generate low-harmonic-vibration frequencies and is simple in structure and easy to realize, and the low frequency representation performance of the loudspeaker is improved.
Description
Technical field
The utility model relates to loudspeaker techniques field, is specifically related to a kind of magnetic circuit and is set to Floating loud speaker.
Background technology
Known, loud speaker, as conventional a kind of electro-acoustic transducer device, for acoustics, is very important electronic devices and components.Existing loud speaker is mainly made up of magnetic circuit, vibrational system and the suspension system for fixing vibrational system; Wherein vibrational system often adopts loudspeaker coil and is positioned at the vibrating diaphragm of loudspeaker coil top, and suspension system mainly adopts the outstanding limit that is positioned at loudspeaker coil top, in the magnetic gap that loudspeaker coil can form at magnetic circuit, moves.The operation principle of above-mentioned loud speaker is, by pass to the alternating current that is attached with voice signal to loudspeaker coil, thereby make loudspeaker coil vibration along the vertical direction in magnetic gap, the up-down vibration of this loudspeaker coil passes to the vibrating diaphragm of its top, thereby vibrating diaphragm makes air vibration reproduced sound.
But in actual use, but there is many defects in existing loud speaker.For example, magnetic circuit is directly fixed on basin frame, has only adopted this single vibrational system of vibrating diaphragm and loudspeaker coil; And the quality that is limited to vibrational system is too small, therefore, the existing structure of loud speaker causes the difficulty that resonance frequency reduces to increase, therefore can not reproduce low frequency signal completely.In existing loud speaker, the restricted reason of vibrational system mass penalty is, first, suspension system is too soft, can not support large quality vibrational system completely and move both vertically continuously; Moreover vibrational system quality is crossed conference and reduces the sensitivity of this vibrational system.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of floated loud speaker of magnetic circuit that can produce low resonant frequency is provided.
The purpose of this utility model is achieved through the following technical solutions:
The floated loud speaker of a kind of magnetic circuit, comprise outstanding limit, vibrating diaphragm, loudspeaker coil, magnetic circuit and speaker frame, the loudspeaker coil that is positioned at vibrating diaphragm below is all connected with outstanding limit with vibrating diaphragm, described loudspeaker coil also falls into the magnetic gap that magnetic circuit forms, the both sides of described loudspeaker coil are fixedly connected with main damper, described magnetic circuit bottom surface is equipped with the secondary damper that supports magnetic circuit, and the two ends of described secondary damper are fixed on speaker frame.
Inventor is in conjunction with the generation principle of low resonant frequency, and main design is, cannot reproduce the deficiency of low resonant frequency by improving the quality of vibrational system to solve existing loud speaker; But inventor considers the puzzlement that in prior art, simple increase loudspeaker coil quality is brought, and solves this problem innovatively by increasing a set of passive acoustic radiation assembly.In conjunction with technique scheme, inventor lays secondary damper under magnetic circuit, magnetic circuit and secondary damper have just formed Floating passive acoustic radiation assembly, and the quality of magnetic circuit own is large, therefore just improve the quality of vibrational system, solved the problem that cannot reproduce low resonant frequency by passive acoustic radiation assembly.
Innovation of the present invention is also, inventor is provided with main damper in loudspeaker coil both sides, and main damper and outstanding limit have formed new suspension system, have solved outstanding limit and have supported hypodynamic technical problem.
As improving technical scheme, described main damper is wavy.
As further improvement technical scheme, described secondary damper comprise with magnetic circuit bottom mating carrier, the stiff end that is connected and is wavy support portion with carrier and be connected with support portion, described stiff end is pressed on the bottom of speaker frame.
The utility model has the following advantages and beneficial effect compared to existing technology:
1. the utility model can produce low resonant frequency, promotes the low frequencies performance of loud speaker;
2. magnetic circuit of the present utility model, at low-frequency resonance, is conducive to magnetic circuit heat radiation, and loudspeaker coil temperature is reduced, and reduces the power output compression causing because of temperature rise;
3. the special construction of practical secondary damper design, makes magnetic circuit in suspended state, improves the quality of sending low resonant frequency;
4. the utility model is simple in structure, is convenient to promote realize.
Brief description of the drawings
Fig. 1 is the profile of the floated loud speaker of the utility model magnetic circuit.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but the execution mode that the utility model is created is not limited to this.
Embodiment
As shown in Figure 1, the utility model provides a kind of magnetic circuit floated loud speaker, comprise outstanding limit 4, vibrating diaphragm 3, loudspeaker coil 2, magnetic circuit 1 and speaker frame 7, the loudspeaker coil 2 that is positioned at vibrating diaphragm 3 belows is all connected with outstanding limit 4 with vibrating diaphragm 3, loudspeaker coil 2 also falls into the magnetic gap that magnetic circuit 1 forms, the both sides of loudspeaker coil 2 are fixedly connected with main damper 5, and magnetic circuit 1 bottom surface is equipped with the secondary damper 6 that supports magnetic circuit 1, and the two ends of secondary damper 6 are fixed on speaker frame 7.
Concrete, main damper 5 is wavy; Secondary damper 6 comprise with magnetic circuit bottom mating carrier, the stiff end that is connected and is wavy support portion with carrier and be connected with support portion, stiff end is pressed on the bottom of speaker frame 7.
In the present embodiment, the specific works principle of the floated loud speaker of magnetic circuit is as follows:
Be placed in after loudspeaker coil 2 energisings in magnetic circuit 1 magnetic gap, under magnetic fields, be in vertical motion, thus the vibrating diaphragm 3 radiation sound of the driving side of being located thereon, and in the time that vibrating diaphragm 3 vibrates, drive passive acoustic radiation assembly resonance, send low resonant frequency.Wherein, main damper 5 and outstanding limit 4 form Primary Suspension system, and support speaker coil 2 moves in the vertical direction; Magnetic circuit 1 is supported by secondary damper 6 and forms passive acoustic radiation assembly, and passive acoustic radiation component suspension is on speaker frame 7.
The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, not departing under prerequisite of the present utility model, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
