Description
Technical field
The utility model relates to electroacoustic field, is specifically related to a kind of Microspeaker.
Background technology
Along with the fast development of information industry and electron trade, Microspeaker, as a kind of electro-acoustic transducing device, has been widely applied in the terminal equipment such as computer, mobile phone.Consulting shown in Fig. 6, is existing Microspeaker pseudo-terminal final assembly schematic diagram.In traditional Microspeaker structure, acoustic aperture 9 ' is often positioned at outer casing bottom, vertical sounding, damping 10 ' is covered in the surface of acoustic aperture 9 ', and the position of outer shell bottom wall and sidewall corresponding product fitting plane is in sustained height, on a horizontal plane, when carrying out final assembly, base plane and the terminal final assembly face of Microspeaker product keep flushing, and the acoustic aperture 9 ' thus in prior art is easily plugged, thus impact installation test curve.
Utility model content
For the problems referred to above, technical problem to be solved in the utility model is: provide a kind of Microspeaker, when part entirety remains unchanged, change the acoustic aperture structure in existing Microspeaker, when Microspeaker product and terminal equipment carry out final assembly, ensure that acoustic aperture can be given vent to anger from the side.
In order to solve the problem, the technical solution of the utility model is:
A kind of Microspeaker, comprises magnetic circuit system, vibrational system and support system; Described magnetic circuit system comprises frame and the magnet be contained in described frame and washer; Described vibrational system comprises vibrating diaphragm and to bond fixing voice coil loudspeaker voice coil with described vibrating diaphragm; Described support system comprises protecgulum and mates with described protecgulum the shell combined, and wherein, described shell comprises diapire and sidewall; The diapire of described shell is provided with the installation portion of accommodating described magnetic circuit system; The diapire of described shell is provided with the fitting plane of assembling with terminal; The position rational height of the diapire described fitting plane corresponding to sidewall of described shell is poor, coordinates formation to dodge inclined-plane; The diapire of described shell is provided with acoustic aperture, and the openend of described acoustic aperture be positioned at described in dodge on inclined-plane.
Wherein, the sidewall of described shell is the rectangular configuration jointly formed by four upstanding edges; The position of the corresponding Microspeaker base plane of described side wall of outer shell, lower than the height of described outer shell bottom wall opposite position, is formed and dodges inclined-plane, and corresponding formation bottom surface is the acoustic aperture on inclined-plane.
Wherein, described frame is rectangular configuration; Described frame comprises the base portion of horizontal direction and vertically outstanding sidepiece; Described frame is fixed on the installation portion of outer shell bottom wall, and the base portion of described frame is the described fitting plane of assembling with terminal.
Wherein, described acoustic aperture is coated with damping; Described damping is rectangular configuration, coordinates fixing, fit in the surface of described acoustic aperture in inclined-plane with the inclined-plane of dodging on described shell.
Wherein, the centre position of described vibrating diaphragm is combined with reinforcement part; The inward flange of described vibrating diaphragm is surrounded on the periphery of described reinforcement part.
After have employed technique scheme, the beneficial effects of the utility model are:
The outer shell bottom wall of the Microspeaker related to due to the utility model is provided with the fitting plane of assembling with terminal, and the position of the diapire of shell and the corresponding fitting plane of sidewall is provided with difference in height, the diapire of shell and sidewall are no longer on a horizontal plane, but work in coordination and to form a downward inclined plane in the bottom of product, when Microspeaker and the terminal such as mobile phone, computer carry out final assembly, the bottom of product does not flush with fitting plane.And acoustic aperture is positioned on the diapire of shell, and its openend is exactly positioned on above-mentioned inclined plane, therefore, although acoustic aperture is still in the bottom of product, but and leave space between fitting plane, can give vent to anger from the side, installation test curve can not be affected because acoustic aperture is plugged.
Because the position of the sidewall corresponding product base plane of shell is lower than the height of outer shell bottom wall opposite position, the fitting plane of shell and terminal formed one obliquely dodge inclined-plane, accordingly, the acoustic aperture that bottom surface is inclined-plane can be formed between shell and frame, change and vertically speak as speaking obliquely, when product and terminal equipment assemble, acoustic aperture is prevented to be plugged.
Due to acoustic aperture being coated with damping, and damping matches with the inclined-plane of dodging of shell, is fitted in the surface of acoustic aperture in inclined-plane, when product and terminal equipment carry out final assembly, the damping of oblique stickup coordinates with the inclined-plane of dodging of shell, ensures that acoustic aperture can be given vent to anger from the side.
In sum, Microspeaker of the present utility model solves the technical problem that the acoustic aperture that causes because product base plane flushes with fitting plane in prior art is easily plugged.Formed between Microspeaker outer shell bottom wall of the present utility model and sidewall and dodge inclined-plane, the openend of acoustic aperture is positioned at above-mentionedly dodges on inclined-plane, and when carrying out final assembly, acoustic aperture does not flush with fitting plane, can give vent to anger from the side, thus can not affect installation test curve.
