[embodiment]
Below the embodiment of main accompanying drawings the utility model.
For the ease of understanding the utility model, will more comprehensively describe the utility model with reference to relevant drawings below.Provided the preferred embodiment of the utility model in the accompanying drawing.But the utility model can be realized with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of the disclosure of the utility model comprehensively thorough more.
Need to prove, when element is called as " being fixed in " another element, it can be directly on another element or also can have element placed in the middle.When an element is considered to " connection " another element, it can be to be directly connected to another element or possibly to have element placed in the middle simultaneously.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement are just for illustrative purposes.
Only if definition is arranged in addition, the employed all technology of this paper are identical with the implication of the those skilled in the art's common sense that belongs to the utility model with scientific terminology.Among this paper in the specification of the utility model employed term be not intended to be restriction the utility model just in order to describe the purpose of concrete embodiment.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1, the hand-hold communication device 100 of the utility model preferred embodiments comprises the body 110 and the back cover 120 of hand-hold communication device.Back cover 120 is located at the rear side of the body of hand-hold communication device.Hand-hold communication device can in this execution mode, be that example describes with the mobile phone for mobile phone, PDA (Personal Digital Assistant, personal digital assistant) or the like.
Hand-hold communication device 100 also comprises display screen 130 and receiver 140.Specifically in this execution mode, display screen 130 is located at body 110 middle parts of hand-hold communication device.Receiver 140 is located at an end in body 110 outsides of hand-hold communication device.
Hand-hold communication device 100 also comprises antenna 150.Preferably, antenna be located at hand-hold communication device the inside of body 110 away from an end of receiver.
Need to prove that ceramic horn 123 is not limited to one, also can be provided with a plurality of as required.Ceramic horn 123 is not limited to be located at an end of back cover matrix part 121, also can be located at back cover matrix part 121 other positions, for example, is located at the middle part of back cover matrix part 121.
In order comparatively securely ceramic horn 123 to be located on the back cover matrix part 121, back cover matrix part 121 offers holding part (figure is mark not), and ceramic horn 123 is contained in the holding part.
Specifically in execution mode, holding part is the groove that is arranged at back cover matrix part 121 1 sides, and the diapire of holding part is provided with double faced adhesive tape or glue, ceramic horn 123 through double faced adhesive tape or glue fixing in holding part.
See also Fig. 2, in other embodiments, holding part is a window, and is provided with casting steel disc 125 in the holding part, and ceramic horn 123 is provided with corresponding to casting steel disc 125.Concrete, ceramic horn 123 and casting steel disc 125 all are located in the holding part through the mode of casting.Casting steel disc 125 can reduce the local thickness of back cover matrix part 121, so that ceramic horn 123 conveniently to be set, and, in the local thickness of less back cover matrix part 121, improve this local structural strength, to keep the overall construction intensity of housing base portion 121.
When back cover 120 is dismountable housing of hand-hold communication device 100; For example; Back cover 120 is the battery cover of hand-hold communication device 100, because the thimble butt of the body 110 of the pad 127 of back cover 120 and hand-hold communication device, then when changing battery; Only need take off back cover 120 and get final product, this moment, pad 127 separated with thimble.When having changed battery, back cover 120 is mounted on the body 110 of hand-hold communication device, at this moment, pad 127 electrically contacts with thimble, thereby ceramic horn 123 is electrically connected with the body 110 interior mainboards (figure does not show) of hand-hold communication device again.
See also Fig. 4, in other embodiments, back cover 120 also comprises lead 128 and attachment plug 129.Lead 128 is electrically connected with ceramic horn 123.The free end of lead 128 is located in attachment plug 129.Attachment plug 129 is electrically connected with the body 110 interior mainboards of hand-hold communication device.
When back cover 120 was dismountable housing of hand-hold communication device 100, for example, back cover 120 was the battery cover of hand-hold communication device 100, when changing battery, took off back cover 120 earlier, got final product pulling up attachment plug 129.When having changed battery; Earlier attachment plug 129 is electrically connected with the main body 110 interior mainboards of hand-hold communication device; Then back cover 120 is mounted on the body 110 of hand-hold communication device, thereby ceramic horn 123 is electrically connected with the body 110 interior mainboards (figure does not show) of hand-hold communication device again.
Be appreciated that; Back cover 120 is not limited to the battery cover of hand-hold communication device 100; For example, when the battery of holding communication device 100 was internal battery, back cover 120 can be one-body molded with the frame of hand-hold communication device 100; If need maintenance hand-hold communication device 100, then the fore shell of detachable handheld communication device 100 gets final product.
Above-mentioned hand-hold communication device 100 adopts the ceramic horn 123 comparatively thinner than the thickness of moving-coil type loudspeaker; And ceramic horn 123 is arranged on the back cover matrix part 121; Thereby saved the inner space of hand-hold communication device 100, made the thinner thickness of hand-hold communication device 100.
And, because ceramic horn 123 is arranged on the back cover matrix part 121, then can not receive the restriction of hand-hold communication device 100 inner spaces size, can on back cover matrix part 121, place the big as far as possible ceramic horn 123 of area, to increase its sound intensity and tonequality.
Above embodiment has only expressed several kinds of execution modes of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
