Abstract
The utility model discloses a flat-panel sound box driver and a vibrating elastic sheet for the same, aiming to solve the problem of distortion easiness of the traditional driver. The vibrating elastic sheet disclosed by the utility model is flaky and is formed by integrating an outer ring, and inner ring and a connecting sheet connected between the two rings, wherein the inner ring and the outer ring are concentric. The flat-panel sound box driver disclosed by the utility model comprises a magnetic loop, a support, a sound coil, the vibrating elastic sheet and a vibration transmission body, wherein the support is annularly fixed above the magnetic loop, the lower end of the sound coil stretches into a magnetic gap of the magnetic loop, the upper end of the sound coil is fixed on the vibration transmission body, the inner ring of the vibrating elastic sheet is sleeved outside the sound coil and is fixed connected with the sound coil, and the outer ring of the vibrating elastic sheet is fixed on the support. According to the flat-panel sound box driver and the vibrating elastic sheet in the utility model, the effect is better at low frequency, the response speed of sound frequency is higher, and the efficiency is higher; and the frequency response range is wider than that of the prior art, and the distortion easiness is prevented.
Description
Technical field
The utility model belongs to the loud speaker field, relates in particular to a kind of plat sound box driver and vibrations shell fragment.
Background technology
Existing audio amplifier driver commonly used, owing to adopt the drive pattern of traditional bullet ripple circle, under electromagnetic action, it is slow to exist response speed, the efficient problem of lower.If play the too light F of ripple
0Can distortion under the low situation.
Summary of the invention
The purpose of the utility model is the problems referred to above to existing audio amplifier driver existence, provides a kind of plat sound box driver and plat sound box driver with the vibrations shell fragment.
The plat sound box driver of the utility model is with the vibrations shell fragment, and it is characterized in that: said vibrations shell fragment is a sheet, by concentric outer toroid and interior annulus and be connected two brace one between the annulus and constitute.
As preferred version, said vibrations shell fragment is provided with four braces, and they equidistantly distribute.
As preferred version, said vibrations shell fragment is processed by metal material, like steel disc or copper sheet etc.
The plat sound box driver of the utility model comprises magnetic loop, support, voice coil loudspeaker voice coil, vibration body and biography shake body, and said support is a ring-type, is fixed on the magnetic loop top, and the lower end of said voice coil loudspeaker voice coil is stretched in the magnetic gap of magnetic loop, and the upper end of voice coil loudspeaker voice coil is fixed on and passes on the shake body; Said vibration body adopts the vibrations shell fragment; The vibrations shell fragment is a sheet; By concentric outer toroid and interior annulus and be connected two brace one between the annulus and constitute, it is outer and is fixedly connected with voice coil loudspeaker voice coil that the interior annulus of vibrations shell fragment is enclosed within voice coil loudspeaker voice coil, and the outer toroid that shakes shell fragment is fixed on the support.
As preferred version, said magnetic loop is made up of U iron, main magnetic, washer, secondary magnetic, and main magnetic places at the interior end of U iron, and washer places main magnetic top, and secondary magnetic places secondary magnetic top; The bottom of said support is fixedly connected with the top of U iron.
The technique effect of the utility model is:
1, effect can be better under low frequency than legacy drive for the driver of the utility model;
2, the driver of the utility model adopts the vibrations shell fragment to replace traditional bullet ripple, is difficult for distortion, and coil scope of activities in magnetic gap is little; Be difficult for making harmonic distortion for the second time; Vibrations shell fragment good permeability, the conduction of sound is well-illuminated more limpid, also is not easy to cause physics tired.
3, adopt the Hz-KHz of driver of the utility model wideer than traditional.

Fig. 2 is the assembly structure sketch map of the utility model embodiment.
Embodiment
Referring to Fig. 1 and Fig. 2; Present embodiment is the plat sound box driver, comprises magnetic loop, support 5, voice coil loudspeaker voice coil 6, vibration body and biography shake body 8, and said magnetic loop is made up of U iron 1, main magnetic 2, washer 3, secondary magnetic 4; Main magnetic 2 places at the interior end of U iron 1; Washer 3 (being magnetic conduction sheet) places the top of main magnetic 2, and secondary magnetic 4 places the top of washer 3, and U iron 1, main magnetic 2, washer 3, secondary magnetic 4 are the connection that fastens with glue each other; Support 5 is for being provided with the ring-type of mesopore, and support 5 is fixed on the magnetic loop top, and the bottom of support 5 is fixedly connected with the top of U iron 1, and both are tight structure spare, compress with punch press; The lower end of voice coil loudspeaker voice coil 6 is passed in the magnetic gap that stretches into magnetic loop behind the mesopore of support 5 (being in the magnetic gap between U iron 1 and main magnetic 2 and the washer 3), and the upper end of voice coil loudspeaker voice coil 6 is enclosed within to pass the peripheral of shake body 8 and be fixed on through viscose glue and passes on the shake body 8; Vibration body adopts vibrations shell fragment 7; Vibrations shell fragment 7 is a sheet; By concentric outer toroid and interior annulus and be connected two brace 701 one between the annulus and constitute, vibrations shell fragment 7 is provided with four identical shaped braces 701 in the present embodiment, and they equidistantly distribute; It is outer and be fixedly connected through viscose glue with voice coil loudspeaker voice coil 6 that the interior annulus of vibrations shell fragment 7 is enclosed within voice coil loudspeaker voice coil 6, and the outer toroid that shakes shell fragment 7 places on the platform 501 at support 5 tops and through viscose glue and is fixed on the support 5.
When being applied to plat sound box, the biography shake body 8 in the present embodiment is connected with the plate diaphragm of loud speaker.In practical application, the irregular vibrations that audio frequency acts on vibrations shell fragment 7 form irregular crooked shock wave with plate diaphragm and conduct through passing shake body 8.The piston type motion that whole effect is different from conventional audio output takes place, and also is superior to legacy drive work commonly used.
The vibrations shell fragment can be processed by metal materials such as steel disc or copper sheets in the utility model.
