Abstract
The invention discloses a kind of double unit receiver of dynamic ferrum, two lower casings including welding symmetrical above and below, the junction of two described lower casings is straight flange, and two described lower casings form common ante-chamber, described common ante-chamber is provided with upper and lower two be symmetrically installed go out sound unit；Be provided with sound mouth in the side of two described lower casings, described lower casing offers common sender in the described side being close to sound mouth.The present invention can accomplish that acoustical behavior is constant in the case of volume is less, the bonding strength of lower casing is higher, owing to defining common ante-chamber after two lower casing combinations, two sound going out sound unit are passed to sound mouth through common sender after can mixing in ante-chamber and are conducted to the external world again, make the loss of volume be preferably minimized.
Description
Technical field
The invention belongs to moving-iron receiver parts, more particularly it relates to a kind of double unit receiver of dynamic ferrum.
Background technology
Moving-iron receiver is mainly used in the wearable device such as sonifer, earphone, audiomonitor, these products all demand sounding
Unit has small size, high output, the feature of low vibrations.Double unit receivers are the special types in receiver, and its ratio is identical
The single unit receiver of volume, exports higher, and structure is more stable, and shakes much lower.So receiving the joyous of a lot of client
Meet.
Existing pair of unit moving-iron receiver structure is: the upper shell of single for two panels receiver is fitted in one in opposite directions
Rise, fix with glue.Then assembling sound mouth.During work, two panels receiver produces sound from respective ante-chamber, then by each
Sender derive, in sound mouth mixing after to outer conduction.
Firstly, since the edge of receiver shell be entirely bevel edge design, cause 2 combination of telephone receivers time
Time cannot use welding procedure, can only be fixed by glue.And the intensity of glue compares welding much lower.So double unit
Overall structure is the most firm.
Secondly, 2 separate units have the ante-chamber of separation, each export to mix sound mouth from ante-chamber by sound.Volume
Lose bigger.
Finally, volume is the least, also has the space improved.
Summary of the invention
The invention discloses a kind of double unit receiver of dynamic ferrum, this receiver optimizes the structure of double unit receiver, makes
Volume loss reduces, reduces space.
The technical solution adopted in the present invention is:
A kind of double unit receiver of dynamic ferrum, including two lower casings of welding symmetrical above and below, the company of two described lower casings
Meet place for straight flange, two described lower casings form common ante-chamber, be provided with upper and lower two and be symmetrically installed in described common ante-chamber
Go out sound unit；Be provided with sound mouth in the side of two described lower casings, described lower casing offers in the described side being close to sound mouth
Common sender.
Further, the junction of two described lower casings uses laser bridge joint welding, is that it is more firm.
Further, going out and respectively comprise a vibrating diaphragm in sound unit described in two, two vibrating diaphragms assemble in opposite directions.
Using after technique scheme, the present invention can accomplish that acoustical behavior is constant in the case of volume is less, lower outside
The bonding strength of shell is higher, and owing to defining common ante-chamber after the combination of two lower casings, two sound going out sound unit can be
Ante-chamber passes to sound mouth through common sender after mixing and is conducted to the external world again, make the loss of volume be preferably minimized.
Accompanying drawing explanation
Fig. 1 is the front view that the present invention moves the double unit receiver of ferrum；
Fig. 2 is the rearview that the present invention moves the double unit receiver of ferrum.
In figure:
1, lower casing 11, straight flange 12, common ante-chamber 13, common sender 2, go out sound unit 3, sound mouth.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.Following example are only used for more clear
Chu's ground explanation technical scheme, and can not limit the scope of the invention with this.
As depicted in figs. 1 and 2, the double unit receiver of a kind of dynamic ferrum, including two lower casings 1 of installation symmetrical above and below, two
The junction of individual lower casing 1 is straight flange 11, there is no chamfering, and two lower casings 1 use laser to carry out bridge joint welding, two lower casings
1 formed common ante-chamber 12, described common ante-chamber 12 is provided with upper and lower two be symmetrically installed go out sound unit 2, under two outside
The side of shell 1 is provided with sound mouth 3, and lower casing 1 offers common sender 13 in the side being close to sound mouth 3.Two go out in sound unit 2
Respectively comprising a vibrating diaphragm, two vibrating diaphragms assemble in opposite directions.
The present invention moves the double unit receiver of ferrum relative to prior art, is the lower casing 1 of straight flange 11 with two basic change edge,
Laser can be used to carry out bridge joint welding, and the intensity glue to be significantly larger than of laser welding is bonding, owing to two lower casings 1 combine
After define common ante-chamber 12, two sound going out sound unit 2 pass to sound through common sender 13 after can mixing in ante-chamber
Mouth 3 is conducted to the external world again, makes the loss of volume be preferably minimized；Finally, due to do not use upper shell, compared to existing technology, use
The present invention can accomplish that acoustical behavior is constant in the case of volume is less, and the thickness that integral thickness at least reduces shell is big
Little.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
