Abstract
The utility model relates to a shell for accommodating a sounding component, which comprises an upper shell body and a lower shell body, wherein the lower shell body is matched with the upper shell body; the upper and lower shell bodies are mutually matched and form a front cavity for accommodating the sounding component and a back cavity which is communicated with the front cavity and used for regulating the property of the sounding component; the upper shell body is provided with a first transitional step with an inclined plane; the lower shell body is provided with a second transitional step with an inclined plane; the inclined planes of the first and second transitional steps are mutually and tightly jointed; the shell further comprises a bottom wall; and the inclined planes of the first and second transition steps are not perpendicular to the bottom wall. Because the inclined planes of the first and second transition steps are not perpendicular to the bottom wall, the bearing capabilities of the transition steps in the glue sealing process are increased and the ultrasonic welding is boosted.
Description
[technical field]
The utility model relates to a kind of microphone device, relates in particular to a kind of shell of accommodating microphone device.
[background technology]
Miniature sound-producing device is widely used in portable electric appts such as mobile phone, notebook computer, hearing aids.Along with the fast development of these portable electric appts, people are more and more stronger to its functional requirement, and the housing that is used to encapsulate microphone device simultaneously also obtains corresponding fast development.
Existing miniature sound-producing device, the gradient of the transition shoulder on the junction between the cavity of encapsulation microphone device monomer is too big or become the vertical transitions of 90 degree, in the glue sealing of housing, because of the stressed little of step or the bonding force that causes glue of not stressing strong inadequately, also can't realize for ultrasonic bonding.
Therefore, be necessary to cause the not strong deficiency of transition shoulder bonding force to improve because of the gradient of transition shoulder is excessive to above-mentioned miniature sound-producing device.
[utility model content]
The purpose of this utility model is to solve above-mentioned miniature sound-producing device and causes the not strong deficiency of transition shoulder bonding force that a kind of housing that encapsulates microphone device is provided because of the gradient of transition shoulder is excessive:
A kind of housing of accommodating microphone device, described housing comprises upper shell and lower house with matching, described upper shell cooperates formation one to accommodate the ante-chamber of microphone device and be communicated with the back cavity that is used to regulate the microphone device acoustical behavior with this ante-chamber with lower house, described upper shell is provided with first transition shoulder on band inclined plane, described lower house is provided with second transition shoulder on band inclined plane, the inclined plane of the inclined plane of described first transition shoulder and second transition shoulder fits tightly mutually, described housing comprises diapire, the described diapire of inclined plane out of plumb of the inclined plane of described first transition shoulder and second transition shoulder.
As a kind of improvement of the present utility model, described first transition shoulder comprises the sidewall vertical with the inclined plane, described sidewall and ante-chamber with the angle between the connecting wall of back cavity be 0 spend to 90 the degree.
As a kind of improvement of the present utility model, described second transition shoulder comprises the sidewall vertical with the inclined plane, described sidewall and ante-chamber with the angle between the connecting wall of back cavity be 0 spend to 90 the degree.
The beneficial effects of the utility model are: described diapire of accommodating the housing of microphone device because of the inclined plane out of plumb housing of transition shoulder in it, so increased the stressed of step, the mild transition shoulder that needs for glue sealing or ultrasonic bonding creates conditions.
[description of drawings]
Fig. 1 is the first visual angle three-dimensional exploded view that the utility model is accommodated housing one embodiment of sounding monomer;
Fig. 2 is the second visual angle three-dimensional exploded view that the utility model is accommodated housing one embodiment of sounding monomer;
Fig. 3 is the front view of an embodiment of the utility model housing of accommodating the sounding monomer.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of housing 1 of accommodating microphone device, described housing 1 comprises upper shell 10 and lower house with matching 11, described upper shell 10 cooperates formation one to accommodate the ante-chamber 100 of microphone device 2 and be communicated with the back cavity 101 that is used to regulate microphone device 2 acoustical behavioies with this ante-chamber 100 with lower house 11, described upper shell 10 is provided with the first transition shoulder 10b of band inclined plane 10a, described lower house 11 is provided with the second transition shoulder 11b of band inclined plane 11a, the inclined plane 11a of the inclined plane 10a of the described first transition shoulder 10b and the second transition shoulder 11b fits tightly mutually, described housing 1 comprises diapire 1a and sidewall 1b from the extended vertical diapire 1a of diapire 1a, the diapire 1a of the inclined plane 11a out of plumb housing 1 of the inclined plane 10a of the described first transition shoulder 10b and the second transition shoulder 11b.
The described first transition shoulder 10b comprises the sidewall 10c vertical with inclined plane 10a, described sidewall 10c and ante-chamber 102 with the angle between the connecting wall 103 of back cavity 101 be 0 spend to 90 the degree, the described second transition shoulder 11b comprises the sidewall 11c vertical with inclined plane 11a, described sidewall 11c and ante-chamber 102 with the angle between the connecting wall 103 of back cavity 101 be 0 spend to 90 the degree.
The gradient by the first transition shoulder 10b and the second transition shoulder 11b excessively mild, when upper shell 10 combines with lower house 11, using glue sealing can increase being stressed of glue, thereby can bring into play the maximum effect of glue, and when ultrasonic bonding seals, also can be because of the easy greatly and more welding of pressure.
Above-described only is better embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
