Description

A kind of Novel receiver shell

Technical field

It the utility model is related to moving-iron receiver structure, and in particular to a kind of design of moving-iron receiver shell.

Background technology

Moving-iron receiver has a small volume, high conversion efficiency, and response is fast, and the features such as high sensitivity, application is more and more extensive. Traditional moving-iron receiver shell is typically interlocked by upper and lower two cans and formed.Traditional Novel receiver shell shortcoming mainly has： 1st, shell material processing is more complicated；2nd, it is essentially hand assembled, it is more difficult to realize automatic assembling.

Utility model content

The novel housing that the utility model provides to solve deficiency of the prior art, is advantageous to moving-iron receiver Automated production, its production efficiency is improved, reduce production cost.

To reach above-mentioned purpose, the technical solution adopted in the utility model is：

A kind of Novel receiver shell, including three upper lid, housing, lower cover parts, housing are closed annular, and Shang Gai is with Cap-shaped shape matches with the cavity shape of housing, and upper lid contacts the lower surface of connection, lower cover and housing with the upper surface of housing Contact connection, so, upper lid, housing, lower cover connect to form box-like receiver shell structure.

As a kind of preferred scheme of Novel receiver shell described in the utility model, described upper lid and/or lower cover It is simple for planar sheet, processing.

As a kind of preferred scheme of Novel receiver shell described in the utility model, described upper lid include capping and Cover rim, cover rim are arranged on capping surrounding and are connected with capping, and preferable cover rim and capping are in 80-100 ° of angle, further, lid Positioning convex is provided with along interior, facilitates the installation of later stage vibrating diaphragm.

As a kind of preferred scheme of Novel receiver shell described in the utility model, described lower cover include capping and Cover rim, cover rim are arranged on capping surrounding and vertical with capping, and the height of cover rim is not higher than the height in vibration reed portion, facilitates tongue The automation installation of reed.

As a kind of preferred scheme of Novel receiver shell described in the utility model, described housing is by automatic stamping Roll and form, seam crossing is connected using welding procedure or adhesive, and processing technology is simple, is easy to automated production.

Further, described housing seam crossing is designed as cross structure, strengthens the mechanical strength of shell.

As a kind of preferred scheme of Novel receiver shell described in the utility model, the housing is by tubular log material Cutting aftershaping is made, housing seamless, and outward appearance is more beautiful.

As a kind of preferred scheme of Novel receiver shell described in the utility model, described upper lid, lower cover pass through Welding procedure and/or adhesive technique for sticking are connected with housing.

As a kind of preferred scheme of Novel receiver shell described in the utility model, there is positioning on described lower lid Device, for aiding in the installation of subsequent parts to position.

Brief description of the drawings

Fig. 1 is a kind of preferably Novel receiver exploded perspective view；

Fig. 2 is another preferably Novel receiver exploded perspective view；

Fig. 3 is another preferably Novel receiver exploded perspective view；

Wherein：

1st, upper lid 2, the sender 2.2 of housing 2.1, vibrating diaphragm positioning convex 3, lower cover 3.1, positioner 4.1, vibrating diaphragm Combination 4.2, motor combination.

Accompanying drawing essentially describes the assembled relation of the housing of lid 2 and 3 lower covers on 1, and 4.1 and 4.2 be called in order to aid in illustrating Device assembly relation, not using this patent receiver necessary structure.

These accompanying drawings have not necessarily been drawn to scale, disclosed embodiment sometimes by graphical sysmbol, dotted line, figure represent and Partial view is shown, under specific circumstances, may have been omitted the details in these figures, these details for disclosed in understanding this Application is unnecessary.It should be appreciated that the disclosure is not limited to illustrate in the accompanying drawings and disclosed specific embodiment again.In short It, it should be apparent to those skilled in the art that a large amount of variation will fall into the disclosure and spirit and scope of the appended claims it It is interior.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Embodiment 1

As shown in figure 1, a kind of Novel receiver shell mechanism, hereinafter referred to as receiver shell, including upper lid 1, lower cover 3, Housing 2.

Housing 2 is closed annular, and cavity shape of upper lid 1 and lower cover 3 shape with housing matches, upper lid and housing Upper surface contact connection, lower cover contact connection with the lower surface of housing.Upper lid 1 is planar sheet.Housing is rolled by automatic stamping Form, be bent into rectangular ring, junction is arranged on receiver short end, and junction is linear joint, by welding procedure or Adhesive connects.

Vibrating diaphragm combination 4.1 and motor combination 4.2 are fixedly mounted in receiver shell, vibrating diaphragm combination 4.1 is arranged on outer inframe The middle and upper part of chamber, housing inwall are provided with vibrating diaphragm positioning boss 2.2, and the space between vibrating diaphragm combination 4.1 and upper lid 1 is ante-chamber, is shaken Space between film combination 4.1 and lower cover is back cavity, and motor combination 4.2 is fixed lower lid above and is contained in back cavity.

In order to coordinate subsequent technique, lower cover includes capping and cover rim, and cover rim is arranged on capping surrounding and, lid vertical with capping It is less than the height in vibration reed portion in motor combination 4.2 along height, facilitates the assembling of tongue.

The upper lid, housing, lower cover are connected by way of welding and/or binding agent adhesion.

Embodiment 2

As shown in Fig. 2 for another preferably Novel receiver exploded perspective view, remaining is same as Example 1, difference It is in housing junction is designed as cross structure, and one joint face has casting lug thereon, and corresponding joint face has hollow out Groove, prominent block-shaped and hollow slots shape adaptation, is connected by welding procedure or adhesive, strengthens the mechanical strength of shell.
