Abstract

An horn modified structure mainly comprises a supporting seat under which a magnetic loop (a round iron) is arranged; a voice coil whose one end is provided with a coil to be arranged inside the magnetic loop and whose top end is coated with a round concave vibration film; and a hanging end, which is characterized in that an upper end of the voice coil is slightly higher than the supporting seat, and one end of the hanging end is adhesive to a surface of the supporting seat and an extended surface of the other end is directly adhesive to an upper part of a cylinder body of the voice coil, thus good push-pull elasticity is acquired and the upside of the voice coil can be emptied, making the vibration film can be independently arranged to increase the area, therefore effectively improving the output voice voltage.

Description

The loudspeaker structure-improved

The utility model relates to a kind of loudspeaker, refers to enlarge the loudspeaker of vibrating diaphragm effective area especially.

Its outstanding limit of habit formula loudspeaker is positioned at the junction of Loudspeaker diaphragm and support body, in order to supporting the periphery of this vibrating diaphragm, and the air flows of blocking vibrating diaphragm front and back, be beneficial to voice coil loudspeaker voice coil and seesaw.Preferable outstanding limit need possess good supporting, suitable biddability, preferable damping capaicty and recovery.Because of the reciprocating motion that good supporting can make voice coil loudspeaker voice coil keep straight line, just the outstanding limit of reason is too not hard for suitable biddability, and pins down the reciprocating motion of voice coil loudspeaker voice coil, or causes its distortion; And damping capaicty and recovery can influence especially in, the distortion of low range.Commonly using its outstanding limit of loudspeaker is to be bonded on the vibrating diaphragm, so there is following shortcoming:

1. it sees through holding of vibrating diaphragm indirect for voice coil loudspeaker voice coil, and can't make voice coil loudspeaker voice coil do the best perpendicular cuts motion stably, easily produces beat and quality distortion when power is big, and output is limited to causing.

2. this see through vibrating diaphragm again with the voice coil loudspeaker voice coil mode of connection, requiring under the high-quality condition, can't make the loudspeaker volume do further effectively to dwindle.

Main purpose of the present utility model is, a kind of modified model loudspeaker are provided, and the voice coil loudspeaker voice coil that not only can keep steady keeps the good vertical motion, and vibrating diaphragm can effectively strengthen the raising acoustic pressure again.

For reaching above-mentioned purpose, the design's loudspeaker comprise supporting seat, voice coil loudspeaker voice coil, the round concave shape vibrating diaphragm of voice coil loudspeaker voice coil upper end, outstanding limit are provided with magnetic and return under the supporting seat, voice coil loudspeaker voice coil is long tubular, stack shell one end is provided with coil and places magnetic to return, and the voice coil loudspeaker voice coil upper end exceeds supporting seat, and the vibrating diaphragm periphery is bonded on the voice coil loudspeaker voice coil; Outstanding limit is the elastomer of stage casing tool wave amplitude, and it is bonding with the support seat surface that an end is received face, and it is mutually bonding with voice coil loudspeaker voice coil stack shell upper lateral part that the other end is received face.Supporting seat is made as tool hole platform, and the platform bottom is established the multijaw shape and met portion, and vibrating diaphragm is a round concave shape sheet metal.By this, lean to one side and to vacate the voice coil loudspeaker voice coil top simultaneously for the outstanding good push-and-pull elasticity of the cemented acquisition in limit, allow vibrating diaphragm can increased area be set independently and effective output sound press that improves with voice coil loudspeaker voice coil.

The utility model has the advantages that: because of stack shell has the design of suitable length,, vacate the voice coil loudspeaker voice coil top simultaneously, allow vibrating diaphragm can increased area be set independently and effectively improve the output sound press so it is cemented for outstanding limit that the voice coil loudspeaker voice coil assembling time is leaned to one side.

Following examples conjunction with figs. is done a detailed description to the utility model structure and characteristics.

Fig. 1 is the utility model three-dimensional exploded view;

Fig. 2 is the utility model schematic perspective view;

Fig. 3 is the utility model structural representation;

Fig. 4 is the utility model action schematic diagram.

Please join Fig. 1-3, the loudspeaker structure-improved of this creation comprises that a supporting seat 1, a voice coil loudspeaker voice coil 2, a vibrating diaphragm 3 and hang limit 4 and form, a supporting seat 1 wherein, on establish a tool hole platform 11, meet portion 12 to return 13 (round iron) in conjunction with a magnetic and divide into a multijaw shape, be provided with washer 131 and magnet 132 in it.Voice coil loudspeaker voice coil 2 has a suitable long stack shell 21, and the one end is established coil 22 and returned in 13 to put at magnetic, and the end in addition of voice coil loudspeaker voice coil slightly exceeds supporting seat 1.Vibrating diaphragm 3 be a round concave shape to be covered in voice coil loudspeaker voice coil 2 tops, preferred embodiment available metal sheet is made.Outstanding limit 4 be the elastomer of stage casing tool wave amplitude 41, and an end is received face 42 and is linked on 11 on the supporting seat platform, and end is received face 43 and directly sticked and be located at voice coil loudspeaker voice coil stack shell 21 upper lateral parts in addition.

Please join shown in Figure 5ly, needn't be directly to keep steady on voice coil loudspeaker voice coil 2 again through vibrating diaphragm 3 because of outstanding limit 4 in its global design, can obtain good push-and-pull elasticity during action, the stationarity of voice coil loudspeaker voice coil 2 vibrations to be strengthened,, and outclassed habit formula product so also can improve manyly on the power output relatively.
