Abstract
A loudspeaker vibration diaphragm for a mobile phone and a tablet computer is disclosed and belongs to the loudspeaker component field. A shortcoming of a conventional loudspeaker vibration diaphragm lies in poor high temperature resistance. The loudspeaker vibration diaphragm for a mobile phone and a tablet computer comprises a thin film and a metal film bonded on the thin film which is a silica gel thin film, the silica gel thin film is formed through silica gel injection moulding operation, and the metal film is adhered on the silica gel thin film in a covering manner through use of glue. The silica gel of the silica gel thin film is characterized in that various additives such as color masters and the like can be added in the silica gel in manufacture processes, and characteristics such as color and the like can be added. The silica gel thin film can be shaped like a rectangular, a circle, a rhombus, a runway and the like. The metal film can be an aluminum film or a titanium film or a foaming paper composite aluminum film (titanium film) or the like. The loudspeaker vibration diaphragm for a mobile phone and a tablet computer is advantaged by high temperature resistance, large power, and good electroacoustic performance.
Description
Technical field
The utility model belongs to loud speaker part field, especially uses the diaphragm of loudspeaker relevant with a kind of mobile phone, panel computer.
Background technology
At present, the diaphragm of loudspeaker that existing making mobile phone or panel computer are used adopts the materials such as PU, PAR, PEEK and compound PU to make substantially, this kind of material high-temperature resistance is poor, high-temperature resistant temperature only has 150 ~ 160 DEG C, exceed the heatproof upper limit can produce the situation that components and parts are malfunctioning or burnt, and mobile phone and panel computer inner space is narrow and small, each electronic devices and components are arranged compacter, easily heat up so inner, can produce the too high situation of local temperature, easily cause vibrating diaphragm to damage.Therefore,, now in the urgent need to a kind of vibrating diaphragm with resistant to elevated temperatures performance, address the aforementioned drawbacks.
Utility model content
The purpose of this utility model overcomes exactly existing vibrating diaphragm and exists resistance to elevated temperatures poor, the defect of easily being burnt, provide a kind of can be high temperature resistant, electroacoustic performance good and high-power New-type loudspeaker vibrating diaphragm.
For this reason, the utility model is by the following technical solutions: a kind of mobile phone, the panel computer diaphragm of loudspeaker, comprise film and be bonded in the metal film on film, it is characterized in that: described film is silica gel thin film, this silica gel thin film is by silica gel injection mo(u)lding, and metal film covers on silica gel thin film by glue is bonding; This kind of silica gel can add the various additives such as look mother in the time making in silica gel increases other characteristics such as its color, and silica gel thin film is shaped as the shapes such as rectangle, circle, rhombus and track type; Described metal film is aluminium film or titanium film or blistering paper composite aluminium film (titanium film) etc.
The utlity model has following beneficial effect: the utlity model has advantage high temperature resistant, that power is large and electroacoustic performance is good.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Wherein, 1, film; 2, metal film.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Fig. 1 ~ Fig. 2, the utility model comprises film 1 and is bonded in the metal film 2 on film, and film 1 is silica gel thin film, and this silica gel thin film is by silica gel injection mo(u)lding, and metal film 2 covers on silica gel thin film by glue is bonding; This kind of silica gel can add the various additives such as look mother in the time making in silica gel increases other characteristics such as its color, and silica gel thin film is shaped as the shapes such as rectangle, circle, rhombus and track type; Described metal film 2 is aluminium film or titanium film or blistering paper composite aluminium film (titanium film) etc.
