Detailed description of the invention

Core of the present utility model is, it is provided that a kind of video camera, the speaker of this video camera passes through sealed fixing device It is seal-installed in base, has evaded speaker and caused the problem of noise because of flow perturbation, improve speaker audio, improve Consumer's Experience.

In order to make those skilled in the art be more fully understood that this utility model scheme, come below in conjunction with Figure of description The utility model is described in further detail.

It should be noted that this specific embodiment is set on the basis of speaker in Fig. 1 before and after the noun of locality, it is positioned at and raises It is front that sound device goes out sound side, is positioned at speaker and deviates from after sound side is.

Referring to Fig. 1, this figure shows by the broken section structure of this utility model a kind of specific embodiment of provided video camera It is intended to.

As it is shown in figure 1, the video camera that this specific embodiment is provided include base 10, speaker 80, front fixture 81, after Fixture 82, front sealing ring 83 and rear sealing ring 84；Wherein, base 10 has containing cavity and outer sound mouth 10a, outer sound mouth 10a connects with containing cavity, and front fixture 81 and rear fixture 82 splice and be fixedly connected to form speaker chambers, and rear fixture 82 is solid Surely being connected in the containing cavity of base 10, front fixture 81 has interior sound mouth 81a, interior sound mouth 81a and connects with speaker chambers, Speaker 80 is installed on speaker chambers and passes through the interior sound mouth 81a outer sound mouth 10a towards base 10, and front sealing ring 83 press-fits In between front fixture 81 and base 10, rear sealing ring 84 press-fits between the Mosaic face of front fixture 81 and rear fixture 82.In order to It is easy to those skilled in the art and is more fully understood that the concrete structure of sealed fixing device, please also refer to Fig. 2 and Fig. 3, wherein, figure 2 conceal the detonation configuration schematic diagram after base for video camera shown in Fig. 1, and Fig. 3 is the structural representation of video camera assembly shown in Fig. 1 Figure.

The speaker 80 of this video camera is installed in sealing space, and this sealing space is by base 10, front sealing ring 83, front Fixture 81, rear sealing ring 84 and rear fixture 82 enclose and form, and seal space and only connect with outer sound mouth 10a, thus evade Because of between speaker 80 and base 10 air current flow and cause the problem of noise, improve speaker 80 audio, significantly improve Consumer's Experience.

Further, with reference to shown in Fig. 1, outer sound mouth 10a is positioned at the center of sound mouth 81a, raises one's voice along speaker On direction (namely by rear to front direction), the area of section of interior sound mouth 81a first successively decreases the most isometrical extension.Preferably, interior Sound mouth 81a includes rear round table surface and the front face of cylinder, and the aperture section transition of the front face of cylinder and rear round table surface connects.

The acoustical signal of speaker 80 is guided and converges to interior sound mouth 81a center by the interior sound mouth 81a of this structure Place, it is ensured that acoustical signal is directly transferred to outer sound mouth 10a, miscellaneous with what the collision of base 10 inwall sent to reduce acoustical signal Volume, thus can improve further by the audio of outer sound mouth 10a transmission.

Understanding with continued reference to Fig. 1, the rear end face of front fixture 81 has and press-fits groove 81e, press-fits groove 81e and interior sound mouth 81a connects, speaker 80 is fixing be plugged in press-fit groove 81e in and the front end face of speaker 80 offset with the bottom land press-fiting groove 81e, The rear end face of rear fixture 82 cover cap speaker 80 and with front fixture 81 split be fixedly connected to form speaker chambers.

Further, after in this specific embodiment, the upper end of fixture 82 is provided with grab 82a, the corresponding position of front fixture 81 Installing and be equipped with the draw-in groove 81b suitable with grab 82a, front fixture 81 lower end is symmetrical relative to grab 82a offers two Individual screwed hole 81c, rear fixture 82 lower end correspondence position also offers two through hole 82b.

During assembling, rear fixture 82 and front fixture 81 first pass through grab 82a and draw-in groove 81b and engage pre-connection, then Again by screw 86 by both fixing connections, assembling processing efficient is quick.

It should be noted that fixture 81 and rear fixture 82 are by engaging pre-connection, processing and assembler before meeting On the basis of skill requires, grab 82a and draw-in groove 81b also can be oppositely arranged, namely grab 82a is arranged at front fixture 81, accordingly Ground, draw-in groove 81b is arranged at rear fixture 82.

Additionally, fixture 81 and front sealing ring 83 can be arranged with split before in this specific embodiment, during assembling, before first adjusting The relative position of sealing ring 83, front fixture 81 and base 10 three is in assembly technology claimed range, the most again by front solid Front sealing ring 83 is pressed in the inwall of base 10 by locking member 81.Obviously, the front fixture 81 of this split type setting and front sealing Circle 83 increases assembly difficulty to a certain extent, and there is, before base assembling, the technology being easily lost and being not easy to take care of Problem.

To this end, with continued reference to shown in Fig. 1, in this specific embodiment, the front end face of front fixture 81 has sealing ring locating slot 81d, the precompressed of front sealing ring 83 is loaded in sealing ring locating slot 81d.
