Abstract
What the utility model discloses a kind of wireless positioning terminal goes out sound structure, comprise upper end cover and bottom end cover, described upper end cover and bottom end cover are respectively arranged with rib and lower rib, loud speaker is provided with between described upper rib and lower rib, described upper end cover is provided with sender, described upper rib circlewise, loudness intensifier is provided with between the internal diameter of described upper rib and upper end cover, described sender is positioned at loudness intensifier, described sender comprises centre bore and multilayer periphery holes, and it is good that it goes out audio fruit.
Description
Technical field
The utility model relates to wireless positioning terminal device field, and particularly, what relate to a kind of wireless positioning terminal goes out sound structure.
Background technology
Along with development and automobile constantly the popularizing in people's life of the communication technology, the utilization of car-mounted terminal is more and more extensive.Car-mounted terminal integrates the abundant function such as location, communication, traffic safety control usually, has powerful traffic scheduling and data-handling capacity, and provides abundant Peripheral Interface to user.
Along with improving constantly of people's living standard and constantly building of road, car-mounted terminal is more and more important, especially wireless positioning terminal.Played to make the loud-speaking effect of loud speaker, it is made to have outstanding broadcast effect, Authorization Notice No. is adopted to be the patent of CN200031873U, it arranges rib on upper end cover and bottom end cover, rib is utilized to be fixed loud speaker, upper end cover and bottom end cover is made to form sound chamber and lower sound chamber, to optimize loud-speaking effect.But the volume in upper sound chamber and lower sound chamber is large, the audio fruit that goes out of sound mouth neither be too desirable.
Utility model content
What technical problem to be solved in the utility model was to provide a kind of wireless positioning terminal goes out sound structure, and it is good that it goes out audio fruit.
The technical scheme in the invention for solving the above technical problem is:
A kind of wireless positioning terminal go out sound structure, comprise upper end cover and bottom end cover, described upper end cover and bottom end cover are respectively arranged with rib and lower rib, loud speaker is provided with between described upper rib and lower rib, described upper end cover is provided with sender, and described upper rib circlewise, is provided with loudness intensifier between the internal diameter of described upper rib and upper end cover, described sender is positioned at loudness intensifier, and described sender comprises centre bore and multilayer periphery holes.
The utility model improves on the basis of existing technology, one, between the internal diameter and upper end cover of upper rib, be provided with loudness intensifier, utilizes loudness intensifier to reduce scattering and disappearing of sound, strengthens the sound intensity at sender place; Its two, the structure of sender and quantity are improved, hole are had and is existingly two-layerly set to multilayer, strengthen and audio fruit.
As preferably, the one-tenth of described loudness intensifier is horn-like, and its loudspeaker nozzle is positioned at the surrounding of sender, is fixed on rib internal diameter at the bottom of loudspeaker.Horn-like, one end that its diameter is larger is loudspeaker nozzle, and what diameter was less is at the bottom of loudspeaker.Trumpet-shaped structure can reduce the diffusion of sound, makes to propagate to sender in sound set, can increase the loudness that sender goes out sound like this; Loudness intensifier is connected between upper end cover and upper rib, also can strengthen the stability of upper bead structures.
As preferably, in order to further strengthen the stability of structure, the contact portion of described loud speaker and upper rib and lower rib is provided with buffer layer.In the process of moving, due to the heavier mass of loud speaker, when vehicle jolts, the pressure of loud speaker to upper rib and lower rib is excessive for vehicle, make rib and lower rib fragile, utilize buffer layer to cushion pressure, strengthen the stability of structure.
Further, described buffer layer is rubber layer.
Further, described buffer layer is froth bed.
Buffer layer should adopt lighter weight and the material of quality softness.Quality softness reaches the object of damping; Because buffer layer is positioned on lower rib, lighter weight, brings burden just can not to lower rib.
To sum up, the beneficial effects of the utility model are:
1, the utility model sets up loudness intensifier between the internal diameter and upper end cover of upper rib, namely in upper sound chamber, arranges loudness intensifier, and what strengthen sound mouth goes out audio fruit.
2, the utility model improves the structure of sender and quantity, hole is had the existing two-layer multilayer that is set to, and strengthens and audio fruit.
3, the contact portion of loud speaker of the present utility model and upper rib and lower rib is provided with buffer layer, utilizes buffer layer to cushion pressure, strengthens the stability of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1, upper end cover; 2, bottom end cover; 3, upper rib; 4, lower rib; 5, loud speaker; 6, buffer layer; 7, loudness intensifier; 8, sender.
Embodiment
Below in conjunction with embodiment and accompanying drawing, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1:
A kind of wireless positioning terminal as shown in Figure 1 go out sound structure, comprise upper end cover 1 and bottom end cover 2, described upper end cover 1 and bottom end cover 2 are respectively arranged with rib 3 and lower rib 4, loud speaker 5 is provided with between described upper rib 3 and lower rib 4, described upper end cover 1 is provided with sender 8, described upper rib 3 circlewise, loudness intensifier 7 is provided with between the internal diameter of described upper rib 3 and upper end cover 1, described sender 8 is positioned at loudness intensifier 7, and described sender 8 comprises centre bore and multilayer periphery holes.
Sender 8 is set to sandwich construction, adds out the area of sound, strengthens and audio fruit.
Embodiment 2:
A kind of wireless positioning terminal as shown in Figure 1 go out sound structure, the present embodiment has done refinement to loudness intensifier on the basis of above-described embodiment, the one-tenth of namely described loudness intensifier 7 is horn-like, and its loudspeaker nozzle is positioned at the surrounding of sender 8, is fixed on rib 3 internal diameter at the bottom of loudspeaker.
Embodiment 3:
A kind of wireless positioning terminal as shown in Figure 1 go out sound structure, in order to strengthen the stability of structure, the present embodiment is optimized on the basis of above-described embodiment, and namely described loud speaker 5 is provided with buffer layer 6 with the contact portion of upper rib 3 and lower rib 4.
Described buffer layer 6 is rubber layer or froth bed.The quality of foam or rubber is soft, can better play cushioning effect, also can not strengthen the pressure of lower rib.
As mentioned above, the utility model can be realized preferably.
