Abstract
The invention aims to provide a receiver shell with a good electromagnetic shielding performance. The receiver shell comprises an upper shell and a lower shell which are connected together, and the key is that the receiver shell further comprises an electromagnetic shielding shell made of metal, wherein the electromagnetic shielding shell is shaped as a box with one open end; the electromagnetic shielding shell covers the lower shell or the upper shell; the side wall of the electromagnetic shielding shell covers a joint of the upper shell and the lower shell. The electromagnetic shielding shell covers the joint of the upper shell and the lower shell, so that an electromagnetic field generated inside a receiver can be avoided from leaking out from the joint of the upper shell and the lower shell, therefore the electromagnetic shielding performance of the receiver is improved. By additionally mounting the electromagnetic shielding shell, which is easy to manufacture and install and relatively low in cost, on the receiver shell, the overall magnetic leakage effect of the receiver can be effectively improved, and the using performance of the receiver in the field of hearing aids and the like can be improved.
Description
Technical field
The invention belongs to electroacoustic apparatus manufacturing technology field, be related specifically to a kind of receiver housing.
Background technology
Traditional receiver housing comprises receiver lower casing and upper casing, lower casing and upper casing adopt glue bonding or resistance, the mode of Laser Welding connects, because lower casing and upper casing are when being connected, under current technique, gap will inevitably be produced (with resistance, if whole piece weld seam will be sealed during laser welding, then can expend more cost and time, and the heat of its welding can have an impact to inside quality, so be generally all only weld several promise firmly at present), when receiver works, its electromagnetic field produced can be leaked by the seam crossing of lower casing and upper casing, in the application of hearing aids and earphone, the electromagnetic field of this leakage can produce interference to the equipment of outside, thus affect the performance of whole equipment.
Summary of the invention
The object of the invention is to propose the good receiver housing of a kind of capability of electromagnetic shielding.
Receiver housing of the present invention comprises the upper casing and lower casing that link together, key is that this receiver housing also comprises a metal electromagnetic shielding shell, described electromagnetic shielding shell is the box-like of one end open, electromagnetic shielding shell covers on lower casing or upper casing, and the sidewall of electromagnetic shielding shell is covered in the seam crossing of upper casing and lower casing.
Above-mentioned electromagnetic shielding shell is covered in the seam crossing of upper casing and lower casing, and the electromagnetic field that receiver inside can be avoided to produce is leaked by the seam crossing of lower casing and upper casing, thus improves the capability of electromagnetic shielding of receiver.
Further, for ease of installing, the sidewall of described electromagnetic shielding shell is provided with breach, and to make this sidewall have elasticity by prestressed mode, the sidewall of electromagnetic shielding shell is fixedly clamped on lower casing or upper casing.After upper casing is fixedly connected with lower casing, only need electromagnetic shielding shell to be buckled on lower casing or upper casing by the mode of pressing, the elasticity that the sidewall of electromagnetic shielding shell can be utilized to have and electromagnetic shielding shell is fixedly connected with lower casing or upper casing.
Specifically, described upper casing and lower casing are connected by glue or laser or electric resistance welding.
Receiver housing of the present invention is easy to processing and manufacturing, installation and lower-cost electromagnetic shielding shell by setting up one, effectively can improve the overall leakage field effect of receiver, improves its serviceability in fields such as hearing aidss.
Accompanying drawing explanation
Fig. 1 is the structural representation of receiver housing of the present invention.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the receiver housing of the present embodiment comprises the upper casing 1 and lower casing 2 that are linked together by glue or laser or electric resistance welding, key is the electromagnetic shielding shell 3 that this receiver housing also comprises a sheet metal part and is stamped to form, described electromagnetic shielding shell 3 is the box-like of one end open, its sidewall 31 is provided with breach 32, by prestressed mode, there is elasticity to make this sidewall 31, electromagnetic shielding shell 3 covers on upper casing 1, and the sidewall 31 of electromagnetic shielding shell 3 clamps the sidewall of upper casing 1 and is covered in the seam crossing of upper casing 1 and lower casing 2.
After upper casing 1 is fixedly connected with lower casing 2, only need electromagnetic shielding shell 3 to be buckled on upper casing 1 by the mode of pressing, the elasticity that the sidewall of electromagnetic shielding shell 3 can be utilized to have and electromagnetic shielding shell 3 is fixedly connected with upper casing 1.Electromagnetic shielding shell 3 is covered in upper casing 1 and the seam crossing of lower casing 2, the electromagnetic field of receiver inside generation can be avoided to be leaked by the seam crossing of lower casing 2 with upper casing 1, thus improve the capability of electromagnetic shielding of receiver.
Claims (3)
1. a receiver housing, comprise the upper casing and lower casing that link together, it is characterized in that this receiver housing also comprises a metal electromagnetic shielding shell, described electromagnetic shielding shell is the box-like of one end open, electromagnetic shielding shell covers on lower casing or upper casing, and the sidewall of electromagnetic shielding shell is covered in the seam crossing of upper casing and lower casing.
2. receiver housing according to claim 1, is characterized in that the sidewall of described electromagnetic shielding shell is provided with breach, and to make this sidewall have elasticity by prestressed mode, the sidewall of electromagnetic shielding shell is fixedly clamped on lower casing or upper casing.
