Abstract
The utility model relates to the technical field of clean rooms and the field of electroacoustic transducers, and specifically relates to a clean-room-specific interphonetelephone loudspeaker device. The device comprises a loudspeaker unit, a microphone unit, a case and a circuit board, and is characterized in that the loudspeaker unit includes a loudspeaker and a loudspeaker cover; the case has an embedded structure formed by a seat and a panel, the seat is mounted in the wall, and the panel covers an open face of the seat and mounted on the wall; and a loudspeaker mounting seat and the loudspeaker cover are mounted on an inner side of the panel, and the loudspeaker mounting seat is fittingly covered by the loudspeaker cover. The device provided by the utility model is advantageous in that, the loudspeaker cover can effectively prevent the positive feedback on the back of the loudspeaker, thereby preventing the electromagnetic waves transmitted from the back of the loudspeaker form interfering the normal operation of the microphone, and preventing the generation of noises.
Description
Technical field
The utility model relates to clean room's technical field and electro-acoustic transducer device field, is specially the speaker unit of a kind of clean room Special answering, phone.
Background technology
In prior art, Special answering machine or telephone set in the clean room exist volume little, the problem that sound can't promote.If sound is excessive, can produces and utter long and high-pitched sounds.This is because circuit produces degenerative result.
Summary of the invention
Main purpose of the present utility model is the negative feedback problem that solves loud speaker, thus uttering long and high-pitched sounds of preventing that loud speaker from producing when dialogue.
For achieving the above object, the utility model provides following technical scheme:
The speaker unit of a kind of clean room Special answering, phone, comprise loudspeaker assembly, microphone assembly, machine box and circuit board, it is characterized in that: described loudspeaker assembly comprises loud speaker and speaker enclosure; The damascene structures that described machine box is made of pedestal and panel, pedestal is installed in body of wall, and panel covers the pedestal opening face and is arranged on metope; The inboard of described panel is provided with loud speaker mount pad and speaker enclosure, and loud speaker mount pad and speaker enclosure cover coupling.
The inboard of described machine box panel also is provided with microphone mount pad and Mike's fan housing, and microphone mount pad and microphone cover cap close coupling.
Also be provided with the speaker wire outlet on described speaker enclosure.
Also be provided with the microphone lines outlet on described Mike's fan housing.
Described panel is PE film printing panel, and the surface is fully smooth, and is totally-enclosed.
The utility model has the advantage of:
1, described speaker enclosure can effectively prevent the feedback at the described loud speaker back side, thereby prevents the normal operation of the described microphone of electromagnetic sound wave interference that the described loud speaker back side gives out, and then prevents the generation of noise, noise.
2, described panel is PE film printing panel, and the surface is fully smooth, and is totally-enclosed; Fully smooth with metope, be easy to clean.While tool water-proof function, available neutral detergent is cleaned.Cleaning material and the instrument that clean room's wallboard is used that clean used in suggestion, cleans simultaneously at the cleaning wallboard.Can satisfy the sterilization requirement of clean room fully.
3, need not to pluck earphone with hand; Button is designed to touch, has avoided contact stain.
4, fully built-in words and the receiver of sending, the profile simplicity generosity does not take up room, without laying dust, without exposing telephone wire.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, utility model is described further.
Embodiment one: as shown in Figures 1 to 3, the intercommunication of a kind of clean room special use of the present utility model, the loud speaker of phone, consisted of by loudspeaker assembly (1), microphone assembly (2), machine box (3), panel (4) and circuit board, the damascene structures that described machine box (3) is made of pedestal (31) and panel (32), pedestal is installed in body of wall, and panel covers the pedestal opening face and is arranged on metope; The inboard of described panel (32) is provided with loud speaker mount pad and speaker enclosure.Described loudspeaker assembly (1) comprises loud speaker (11) and speaker enclosure (12), and loud speaker (11) is arranged on the inboard speaker base of panel (4).Described microphone assembly (2) comprises microphone (21) and Mike's fan housing (22), and microphone (21) is arranged on the inboard Microphone stand of panel (4).
Described speaker enclosure (12) can effectively prevent the feedback signal diffusion at described loud speaker (11) back side, thereby prevents that the sound wave that described loud speaker (11) back side gives out from disturbing the normal operation of described microphone (2), and then prevents the generation of noise, noise.Described machine box (3) is Embedded to be installed in body of wall, and fully built-in words and the receiver of sending do not take up room, without laying dust, without exposing telephone wire.Described panel (4) is PE film printing panel, and the surface is fully smooth, and is totally-enclosed; Fully smooth with metope; The tool water-proof function, surperficial sterilization capable of washing, available neutral detergent is cleaned, and cleaning material and the instrument that clean room's wallboard is used that clean used in suggestion, cleans simultaneously at the cleaning wallboard.
To sum up, of the present utility model being skillfully constructed, design is unique, novelty simple for structure, both safety clean, can satisfy the antiseptic hygiene requirement of clean room; Can effectively prevent the generation of positive feedback again.Thereby prevent the normal operation of the described microphone of electromagnetic sound wave interference that the described loud speaker back side gives out, and then prevent the generation of noise, noise.Have significant economic and social benefit, very important practical value is arranged, be suitable for large-scale promotion application.
In this specification, the utility model is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.Any unsubstantiality of those skilled in the art is changed and is all fallen in protection range of the present utility model.
