Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments are not limiting as the present invention, structure, method or conversion functionally that those of ordinary skill in the art is made according to these embodiments are all contained in protection scope of the present invention.
It should be noted that orientation described herein is all with acoustic structure normal mounting state on refrigerator as reference, such as, the front of panel is installed, it is i.e. panel to be installed towards side surface refrigerator outside, the back side of panel is installed, is i.e. an installation panel side surface towards refrigerator inside.
Seeing Fig. 1 to 6, the anti-coupling acoustic structure 100 on a kind of refrigerator, including installing panel 1, for being connected with refrigerator door 4 or casing 5, described installation panel 1 is provided with some through holes 11；
Head unit 2, is arranged at described installation panel 1 reverse side；
Gap 6 is had between described head unit 2 and described installation panel 1 back side.
It should be noted that through hole 11 is to run through installation panel 1 front, the aperture at the back side, its object is to increase the permeability between head unit 2 and external environment condition, facilitate sound to external communication.
Head unit 2 and installation panel 1 interval are arranged, owing to having one section of safe distance between head unit 2 and installation panel 1, carry out electromagnetic compatibility experiment at refrigerator, to when installing panel 1 front applying electrostatic, head unit 2 is not susceptible to electrostatic coupling, is of value to the experimental precision ensureing electromagnetic compatibility experiment.
Simultaneously, owing to head unit 2 in use self, with vibrations, is close to install panel 1 and is arranged easily and install panel 1 generation resonance, affect tonequality, head unit 2 and installation panel 1 are arranged at intervals with and benefiting suppression resonance generation, can promote the tonequality of acoustic structure.
Seeing Fig. 1, in the present embodiment, acoustic structure is arranged on refrigerator door 4 side, and when height is stood with adult, head position is roughly equal, so, head unit 2 can be made under majority uses sight closer to user ear, be of value to the more preferable audibility of acquisition.
Further, seeing Fig. 5 and Fig. 6, the anti-coupling acoustic structure 100 on a kind of refrigerator also includes the tubular enclosing portion 3 of both ends open, between head unit 2 and installation panel 1, for promoting the directivity of described head unit 2 sounding.
Head unit 2 for refrigerator is generally powered by miniature internal battery, power is put little outside it, in addition the sound wave that head unit 2 sends is to surrounding dispersive propagation, the direction of propagation of a part of sound wave deviate from orientation residing for user (altitude azimuth that when orientation residing for user refers to normally use refrigerator, user may be in), such as, the sound wave upwardly propagated to reflect several times through metope could enter human ear, and decay is serious, directly influences the audibility of user.
After arranging enclosing portion 3, the sound wave that head unit 2 sends outwards is propagated by the through hole 11 installed on panel 1 after inwall reflection in enclosing portion 3 is gathered again so that sound wave concentrates on orientation residing for user, is of value to the audibility promoting user.
Seeing Fig. 2, in the present embodiment, described through hole 11 is arranged in array on described installation panel 1, and covers the region, big portion installing panel 1.Due to the effect of gathering in enclosing portion 3, in the range of major part sound wave all concentrates on enclosing portion 3, in other embodiments of the present invention, through hole 11 can also be positioned only at described installation panel 1 and be positioned at the region in described enclosing portion 3.
In the present embodiment, described enclosing portion 3 extends to and described head unit 2 front face from described installation panel 1 back side, enclosing portion 3 extends from installing panel 1 back side, i.e. it is structure as a whole with installation panel 1, enclosing portion 3 can be facilitated and the injection manufacture of panel 1 is installed, enclosing portion 3 contacts with head unit 2, the two closely cooperates and forms the poly-sound structure of single-open (installing the through hole 11 on panel 1), it is possible to prevent sound wave from enclosing portion 3, the cooperation gap of head unit 2 is revealed, certainly, it is not precluded from enclosing portion 3 in other embodiments of the present invention and can also use Split type structure with installing panel 1.
Concrete, described head unit 2 includes connecting plate 21 and loudspeaker 22, described loudspeaker 22 are fixed on described connecting plate 21, described connecting plate 21 is detachably fixed with described installation panel 1 and is connected, described loudspeaker 22 are directed at the open-ended place in described enclosing portion 3 and arrange, described enclosing portion 3 near the internal diameter of described loudspeaker 22 1 side ports equal to the external diameter of described loudspeaker 22.In other embodiments of the present invention, enclosing portion 3 can also be more than the external diameter of described loudspeaker 22 near the internal diameter of described loudspeaker 22 1 side ports, it is ensured that loudspeaker 22 can be contained interior by the size of enclosing portion 3 port.
Described connecting plate 21 outer rim is provided with clasp 23, and described installation panel 1 back side is provided with projection 12, and described projection 12 is provided with screw, and institute's connecting plate 21 is by being connected on described installation panel 1 through the bolt of described clasp 23 and described screw.Relative to the existing mode that snaps connection, the connected mode that above-mentioned buckle, bolt, screw coordinate is more solid and reliable, and head unit 2 will not cause displacement because of the vibrations of self during broadcast.Screw is arranged on projection 12, it is possible to use projection 12 supports head unit 2, head unit 2 is separated with installing panel 1, self-assembling formation gap 6.
Furthermore, the least being difficult to of the distance in gap 6 plays the effect preventing electrostatic coupling, apart from excessive, mean that the integral thickness of acoustic structure increases, can occupy more refrigerator heat-insulation layer space during installation, affecting the heat-insulating property of refrigerator, described gap 6 is preferably 7-10 millimeter.
In order to the outward appearance making refrigerator is more attractive in appearance, and also to convenient installation, processing, described installation panel 1 is embedded on refrigerator door 4 or casing 5, and its front face surface is in the same plane with the outer surface of residing refrigerator door 4 or casing 5.
The present invention is by head unit and installs the setting of panel interval, it is not susceptible to electrostatic coupling when refrigerator does electromagnetic compatibility experiment, it is of value to guarantee experimental precision, it also avoid simultaneously head unit in use with install panel resonance, affect tonequality, and enclosing portion has the effect gathering sound, the directivity of the sent sound of head unit can be promoted, it is thus achieved that preferably audibility.
Last it is noted that embodiment of above is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to aforementioned embodiments, it will be understood by those within the art that: the technical scheme described in aforementioned each embodiment still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the present invention each embodiment technical scheme.
