The portable computer is characterized in that the supporting part arranged in the keyboard part of the portable computer consists of the metal supporting plate, the through holes are arranged on the surface of the metal supporting plate, and the film is partially fixed onto the surface of the metal supporting plate in a manner without interference of the key caps with the circuit board.
Description
Technical field
The utility model relates to a kind of loadspeaker structure, particularly a kind of loadspeaker structure of constructing jointly with portable computer keyboard.
Background technology
According to current notebook computer development trend, notebook computer is constantly developing to lightening and entertainment orientation direction.As a kind of amusement equipment, notebook computer often need be finished the work of audio plays.The work of this audio plays is normally finished by the loud speaker in the notebook computer.But the shared space of the result of broadcast of existing loud speaker and loud speaker often is directly proportional.This conflicts with lightening generation of realizing notebook.In order to keep the smaller size smaller of notebook computer, some notebook computers select to use the very little loudspeaker of volume.But this has caused the sound of loud speaker too small, can't satisfy user's demand.Therefore, according to existing speaker design, be difficult to be implemented in and guarantee the effect that the notebook computer volume is lightening when guaranteeing the loudspeaker plays effect.In order to address this problem, the invention provides a kind of novel loadspeaker structure.
The utility model content
The utility model provides a kind of loadspeaker structure that has, and it comprises: the surface is provided with the metal profile of a plurality of through holes; And the film that partly is fixed on described metal profile surface.In a kind of embodiment of the present utility model, described metal profile is made of the metal profile of portable computer keyboard.And described film is to be made of the composite material that comprises electric conducting material and insulating material, and thickness can be for being 0.25mm.
Loadspeaker structure of the present utility model utilizes the combination of metal profile and vibration of thin membrane generation part, is made into the new device of set keyboard and loud speaker dual-use function.Since the very frivolous and keyboard of this vibration of thin membrane microphone device in conjunction with after, can the gauge of complete machine not exerted an influence.And the via design of metal profile makes sound be easy to be sent in user's the ear, and sounding effect is obvious.
The utility model also provides a kind of portable computer, and its keyboard device comprises keycap, circuit board and support component, it is characterized in that: the support component that is arranged in the described portable computer keyboard parts is made of metal profile, and the surface is provided with a plurality of through holes; And, in the mode of not interfering mutually with described keycap, circuit board and other parts, divide the ground fixed film in the upper surface of described metal profile.
Description of drawings
Fig. 1 shows the stereogram according to the loadspeaker structure of the utility model embodiment.
Embodiment
As shown in Figure 1, the loud speaker according to the utility model embodiment comprises: the metal profile (1) that is provided with a plurality of through holes; And film (2), described film (2) is fixed on described metal profile (1) surface, and part covers described a plurality of through hole or all covers described a plurality of through hole.This metal profile (1) has a first make contact, this first make contact is used for being connected with the mains terminals or the signal line end of a sound source wire, this film (2) has one second contact, and this second contact is used for being connected with the signal line end or the mains terminals of a sound source wire.
In loud speaker, be to constitute by the composite material that comprises electric conducting material and insulating material as the film (2) of vibrating mass according to the utility model embodiment.It has conductivity and pliability this film.Thickness can be 0.25mm.And this film can be fixed to the surface of metal profile to put fixing mode by the whole bag of tricks; As each one section fixing distance, a dotted region on the film is bonded to the surface of metal profile.
Second embodiment of the present utility model provides a portable computer, keycap, circuit board, is used to support the metal support component and the film of described keycap and described circuit board, and this metal support member has a plurality of through holes.This film with not with described keycap and described circuit board mutually the mode of mutual interference be fixed on the surface of described metal profile, part covers described a plurality of through hole or all covers described a plurality of through hole.The keyboard of existing portable computer is configured to the bottom usually and has a metal profile (1).And this metal profile has several through holes on (1), and in according to portable computer of the present utility model, this metal support component is metal profile (1), has partial fixing one film (2) of several through holes on the surface of metal profile (1).Certainly, several through holes on this metal profile (1) can be covered with whole metal profile (1).At this moment, film (2) is fixed on this metal profile (1), covers the part of described several through holes; What certainly can understand is that better for making sounding effect, when the size of this film (2) and this metal profile (1) consistent size, this film (2) covers the whole of described some through holes.Two lead-in wires (Pin) of portable computer sound source wire are connected respectively on metal profile (1) and the film (2).When speaker operation,, be input to metal profile (1) and film (2) respectively by lead-in wire as the voice signal of sound card from the source of sound element of portable computer.Owing to there is tone currents to pass through, can the generation the action of a magnetic field between metal profile (1) and film (2), can make like this to be fixed on the lip-deep film of metal profile (1) (2) and to shake, thereby sound.And the sound that vibration produces can be by being arranged on the outside that through hole on the metal profile (1) is sent to portable computer smoothly.
Existing portable computer keyboard is constructed usually except having a metal profile (1), also comprise: a plurality of keycaps and circuit board, for normal use and the assurance film (2) that does not influence keyboard cooperates sonorific effect with metal profile (1), among another embodiment of the present utility model, film (2) is fixed on the surface of metal profile (1), and is positioned at not the position of disturbing mutually with other parts of portable computer keyboard parts.。For example, with the top that the button and the circuit board of keyboard is positioned at this metal profile (1) upper surface, film (2) is fixed on the lower surface of this metal profile (1).Perhaps, be fixed on the upper surface of this metal profile (1), but not with the circuit board place of mutual interference mutually.
This portable computer can be a notebook computer, mobile phone, PDA, panel computer, e-book, electronic dictionary etc.
The above only is an execution mode of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
