It states sounding monomer to be arranged at intervals with the protecgulum and surround the preceding operatic tunes jointly, the sound passage of leading connects the preceding operatic tunes with extraneous
It is logical, it is described to lead sound passage and the preceding operatic tunes is collectively formed ante-chamber, the protecgulum includes body part, through the body part and with
The through hole and be placed on the through hole completely and be fixed on the steel disc of the body part that the ante-chamber connects, the steel disc are included by it
It protrudes the lug boss to be formed close to a direction for being laterally away from the rear cover of the rear cover and is prolonged by the periphery of the lug boss
That stretches is fixed on the fixed part of the body part.
Preferably, the lug boss includes the first lug boss and leads sound passage side along close to described by first lug boss
To the second lug boss of extension, first lug boss is fully located at the sounding monomer model to the orthographic projection in the rear cover direction
In enclosing, second lug boss is fully located at described lead in sound channel range to the orthographic projection in the rear cover direction.
Preferably, orthographic projection of first lug boss to the rear cover direction is completely superposed with the sounding monomer.
Preferably, the steel disc is further included by multiple reinforced walls for extending to form of fixed part bending, it is multiple described plus
It the spaced setting of strong wall and is embedded and is fixed on the body part.
Preferably, the steel disc is integrated injection molding with the body part.
Compared with correlation technique, loudspeaker enclosure provided by the invention the protecgulum set through thereon and with the ante-chamber
The through hole of connection, by the way that steel disc is set to be covered on the through hole, the steel disc is included by it after the one of rear cover is laterally away from
The lug boss to be formed is protruded in the direction of lid, which increases the volume of the ante-chamber, so as to effectively improve the loud speaker
The acoustical behavior of case.
Description of the drawings
Fig. 1 is the dimensional structure diagram of loudspeaker enclosure of the present invention；
Fig. 2 is the part isometric structural decomposition diagram of loudspeaker enclosure of the present invention；
Fig. 3 is the sectional view of the line A-A along Fig. 1.
Specific embodiment
Below in conjunction with drawings and embodiments, the invention will be further described.
Please join simultaneously shown in Fig. 1-3, the present invention provides a kind of loudspeaker enclosure 100, including protecgulum 1, rear cover 2, sounding monomer 3
And lead sound passage 4.
The rear cover 2 is covered on the protecgulum 1 and surrounds receiving space 10 jointly.The protecgulum 1 and the rear cover 2 can be
Integral structure or Split type structure.
Specifically, the protecgulum 1 include body part 11, through the body part 11 set through hole 12 and be placed on institute completely
It states through hole 12 and is fixed on the steel disc 13 of the body part 11.For example, the steel disc 13 is integrated injection with the body part 11
Shaping, its certain fixed form are without being limited thereto.
The collecting of sounding monomer 3 is fixed in the receiving space 10.The sounding monomer 3 is by the receiving space 10
The operatic tunes 5 and back cavity 101 before being separated into.
That is, the sounding monomer 3 is arranged at intervals with the protecgulum 1 and surrounds the preceding operatic tunes 5 jointly；The hair
Sound monomer 3 surrounds the back cavity 101 jointly with the protecgulum 1 and the rear cover 2.
The sound passage 4 of leading is formed in the receiving space 10.Specifically, it is described lead sound passage 4 be formed at it is described before
Lid 1 can be an integral molding structure with the protecgulum 1.
Ante-chamber 102 is collectively formed with the preceding operatic tunes 5 in the sound passage 4 of leading, and the preceding operatic tunes 5 is in communication with the outside.
The through hole 12 is connected with the ante-chamber 102.That is, in present embodiment, the steel disc 13 is at least partly
It is set with 102 face of ante-chamber.
Specifically, the direction that the steel disc 13 includes being laterally away from the rear cover 2 close to the one of the rear cover 2 by it is protruded
The lug boss 131 of formation is fixed on the fixed part 132 of the protecgulum 1 and by institute by what the periphery of the lug boss 131 extended
It states fixed part 132 and bends the multiple reinforced walls 133 extended to form.
Described 131 at least part of lug boss is set with 102 face of ante-chamber, such as at least partly with the preceding operatic tunes 5 just
To setting.Because 131 structure of lug boss causes the spacing distance of the steel disc 13 and the sounding monomer 3 to increase, that is, increase
The volume of the ante-chamber 102 and the oscillation distances of sounding monomer 3, so as to achieve the purpose that improve 102 audio performance of ante-chamber.
In present embodiment, the lug boss 131 includes the first lug boss 131a and by the first lug boss 131a edge
Close to the second lug boss 131b for leading the extension of 4 direction of sound passage.
The first lug boss 131a is fully located to the orthographic projection in 2 direction of rear cover in the range of the sounding monomer 3.
I.e. described first lug boss 131a and 3 face of sounding monomer are set, so as to add the cavity volume of the preceding operatic tunes 5 and
The oscillation distances of sounding monomer 3.More preferably, orthographic projections and the hair of the first lug boss 131a to 2 direction of rear cover
Sound monomer 3 is completely superposed.
The second lug boss 131b is fully located at described lead in the range of sound passage 4 to the orthographic projection in 2 direction of rear cover.
I.e. described second lug boss 131b leads the setting of 4 at least part face of sound passage with described, and described sound passage 4 is led so as to add
Cavity volume.
It should be noted that because the second lug boss 131b is extended to form by the first lug boss 131a, it is described to lead
Sound passage 4 is connected with the preceding operatic tunes 5, described to lead the position that sound passage 4 is connected with the preceding operatic tunes 5 as transition portion, and should
Transition portion makes the width for leading sound passage 4 most narrow.Therefore, the second lug boss 131b leads to essentially as the sound of leading
A part of wall construction in road 4.That is, sound is led equivalent to increase described in the second lug boss 131b described in the transition portion
Passage 4 the transition portion position height and width, so as to fulfill the purpose of the cavity volume of sound passage 4 is led described in raising,
And then improve the acoustical behavior of the loudspeaker enclosure 100.
The fixed part 132 is fixed on the body part 11 of the protecgulum 1, forms sealing structure.
The reinforced wall 133 includes multiple and is extended to form by the fixed part 132 bending, multiple reinforced walls 133
It spaced setting and is embedded and is fixed on the protecgulum 1, this arrangement enhances 13 fixing intensity of steel disc, and then described in improving
The reliability of loudspeaker enclosure 100.
Compared with correlation technique, loudspeaker enclosure provided by the invention the protecgulum set through thereon and with the ante-chamber
The through hole of connection, by the way that steel disc is set to be covered on the through hole, the steel disc is included by it after the one of rear cover is laterally away from
The lug boss to be formed is protruded in the direction of lid, which increases the volume of the ante-chamber, so as to effectively improve the loud speaker
The acoustical behavior of case.
The foregoing is merely the embodiment of the present invention, are not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made directly or indirectly is used in other relevant skills
Art field, is included within the scope of the present invention.
