Description
Technical field
The utility model belongs to receiver field, is more particularly to a kind of receiver with larger sound radiation pressure.
Background technology
The acoustic part of the dynamic iron balance receiver of tradition includes preceding air chamber, rear gas chamber, sound guide tube and vibrating diaphragm.Work as diaphragm oscillations
When, sound press is produced by sound guide tube radiation.It is that sound guide tube radiation acoustic resistance is very big in place of the shortcoming and defect of this structure, institute
To limit the size of sound radiation pressure, therefore limited in terms of application field.
Utility model content
The purpose of this utility model is to provide a kind of receiver with larger sound radiation pressure.
According to one side of the present utility model there is provided a kind of receiver, including box body, connecting rod and positioned at box body
The interior motor sub-assembly and diaphragm unit that are connected by connecting rod, box body be at top opening structure, the opening of box body provided with number
Cylinder, the edge of the box opening is connected with the edge of the horn, and the edge of diaphragm unit and the madial wall of box body are connected, film
Motor sub-assembly is provided with piece component and box body formation closed housing, closed housing.Box body is designed as hatch frame, and in box body
Hatch frame at the index serpentine pipe design lifting of horn is set to the radiation sound press of open space, significant increase receiver
To the acoustic radiating ability of open field.
In some embodiments, horn is structure as a whole with box body.The horn and box body of integrative-structure are not only solid resistance to
With, and the operating procedure by horn and box body connection is also eliminated, reduce production cost.
In some embodiments, horn is horn-like, and the bore of one end that the horn is connected with the box body is less than
The bore of the other end of the horn.Be conducive to improving the acoustic radiating ability of receiver.
In some embodiments, diaphragm unit includes film frame, and the madial wall stickup of film frame and box body is connected.It is easy to
Operate and damage will not be caused to diaphragm unit and box body.
In some embodiments, the outside of box body is provided with binding post, and motor sub-assembly includes coil, binding post and line
Circle connection.Receiver is connected by binding post with outside source.
In some embodiments, the horn designs for index serpentine pipe.The split emptying of index serpentine pipe design lifting
Between radiation sound press, significant increase acoustic radiating ability of the receiver to open field.
Brief description of the drawings
Fig. 1 is a kind of structural representation of receiver of the embodiment of the utility model one.
Embodiment
Fig. 1 schematically shows a kind of receiver of embodiment of the present utility model.As shown in figure 1, the receiver bag
Include box body 1 and diaphragm unit 2 and motor sub-assembly 3 in box body 1.
Box body 1 is open-topped rectangular parallelepiped structure.At the opening of box body 1 be provided with horn 11, box body 1 be open edge with
The edge connection of horn 11.By the top design of box body 1 be opening rectangular parallelepiped structure, and at the opening of box body 1 set number
The index serpentine pipe design of cylinder 11 increases the radiation impedance of receiver, lifts its radiation sound press to open space, greatly carries
Acoustic radiating ability of the receiver to open field is risen.In order to further improve the acoustic radiating ability of receiver, horn 11 is
Horn-like, the bore of one end that horn is connected with the box body is less than the bore of the other end of horn.Horn 11 is one with box body 1
Body structure, the horn 11 and box body 1 of integrative-structure is not only durable, and also eliminates connect horn 11 and box body 1
Operating procedure, reduces production cost.
Continue as shown in figure 1, diaphragm unit 2 includes film frame 21, diaphragm 22 and the flutter 23 being fitted and connected successively.Diaphragm
Frame 21 is the square frame shape provided with square inner bore 211, and the outward flange of film frame 21 is pasted with the madial wall of box body 1 to be connected, and is easy to behaviour
Make and damage will not be caused to diaphragm unit 2 and box body 1.Film frame 21 is provided with square inner bore 211, and diaphragm 22 covers all film
The square inner bore of piece frame.Flutter 23 is square block, and one side of flutter 23 is overlapping with film frame 21, its excess-three side of flutter 23 and film
Gap is provided between the endoporus of piece frame 21, is easy to the vibration of flutter 23.Diaphragm unit 2 and the formation closed housing 4 of box body 1.Diaphragm
Passage (not marked in figure) is offered on component 2 so that closed housing 4 is in communication with the outside, it is ensured that the normal work of receiver.
Motor sub-assembly 3 is provided with closed housing 4.Motor sub-assembly 3 includes coil 31, U-shaped armature 32, magnet frame 33 and two pieces
Magnet 34.Coil 31 and magnet frame 33 are pasted with the bottom of box body to be connected.The interior top of two blocks of magnet 34 respectively with magnet frame 33
Portion and inner bottom part connection.One end of U-shaped armature 32 is connection end, and the other end is free end.The connection end of U-shaped armature 32 and magnet
The outer surface connection of frame 33, the free end of U-shaped armature 32 is through coil 31 positioned at two blocks of magnet 34.U-shaped armature 32 and line
Circle 31 is not contacted, and U-shaped armature 32 is not contacted with two blocks of magnet 34.The end of the free end of U-shaped armature 32 is provided with contiguous block, connection
