Abstract
The utility model relates to an audio engineering field, concretely relates to outdoor portable speaker, including shell and the sound transmission hole of setting in the shell side, the shell lower part is equipped with the vacuum chuck of the system of glue, the last evacuation pore that has to run through this sucking disc surface of opening of vacuum chuck, the shell passes through rotary mechanism with vacuum chuck and is connected, the shell upper surface is equipped with the fin, speaker shell inboard is equipped with the waterproof ventilated membrane of one deck. The utility model discloses the structural fin that utilizes around the shell dispels the heat, prevents the ageing serious phenomenon that speaker high temperature caused, vacuum chuck's structure makes fixed that the speaker can be random, has increased the stability and the adsorptivity of speaker, rotary mechanism sets up the music direction of propagation that can adjust the speaker, hang the portability that more is favorable to the speaker that relates to of detaining, the design of compass can confirm that the position is difficult to get lost when making outdoor use.
Description
Technical field
The utility model belongs to electroacoustic techniques field, is specifically related to a kind of outdoor portable loud speaker.
Background technology
Loud speaker in earphone can convert the electrical signal to acoustical signal and be radiated the electroacoustic transducer gone in air.Traditional loud speaker is divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.In the loud speaker of each type, using is dynamic speaker at most, the most widely, is also called coil-moving speaker.
Along with improving constantly of the market demand, loud speaker to slimming future development, and requires that its sound quality is become better and better, and vibrating diaphragm is the core component of the acoustical devices such as loud speaker, also just improves the requirement of its acoustical behavior thereupon.Vibrating diaphragm in relevant technology can be difficult to a kind of single film the transaudient effect reaching vibrating membrane loudspeaker low frequency, and composite diaphragm is following a kind of development trend.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of outdoor portable loud speaker, overcome the deficiencies in the prior art, reasonable in design, compact conformation, because the temperature of open air is higher, structure utilizes the fin of ambient envelope dispel the heat, prevent the aging serious phenomenon that loud speaker high temperature causes; It is fixing that the structure of vacuum cup makes that loud speaker can be random, adds stability and the adsorptivity of loud speaker; Rotating mechanism the music communication direction that can regulate loud speaker is set.
The technical program content is as follows:
A kind of outdoor portable loud speaker, comprise shell and the penetrable sound hole being arranged on shell side, described shell front end portion is provided with the vacuum cup that glue is made, its inside is fixed with sounder circuit plate, described vacuum cup has one run through this chuck surface vacuumize duct, described shell is connected by rotating mechanism with vacuum cup, described outer casing back face is provided with the fin of multi-disc sheet, fin is by being fixedly welded on outer casing back face, be provided with one deck waterproof ventilated membrane inside described speaker housings, be arranged at outside sounder circuit plate.
Preferably, the side of described shell is also provided with indicator light.
Preferably, described upper surface of outer cover is provided with and buckles.
Preferably, described shell is also provided with compass.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model provides a kind of outdoor portable loud speaker, because the temperature of open air is higher, structure utilizes the fin of ambient envelope dispel the heat, prevents the aging serious phenomenon that loud speaker high temperature causes; It is fixing that the structure of vacuum cup makes that loud speaker can be random, adds stability and the adsorptivity of loud speaker; Rotating mechanism the music communication direction that can regulate loud speaker is set; What buckle relates to the portability being more conducive to loud speaker; The design of compass makes can confirm that orientation is not easy to get lost during outdoor use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Reference numeral is as follows:
1: shell, 2: penetrable sound hole, 3: vacuum cup, 4: vacuumize duct, 5: rotating mechanism, 6: fin, 7: waterproof ventilated membrane, 8: buckle, 9: compass.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, should be appreciated that structure of the present utility model is not limited in following examples:
As shown in Figure 1, a kind of outdoor portable loud speaker, comprise shell 1 and the penetrable sound hole 2 being arranged on shell 1 side, shell 1 bottom is provided with the vacuum cup 3 that glue is made, its inside is fixed with sounder circuit plate, vacuum cup 3 has one run through this chuck surface vacuumize duct 4, shell 1 is connected by rotating mechanism 5 with vacuum cup 3, shell 1 rear end face is provided with the fin 6 of multi-disc sheet, fin 6 is by being fixedly welded on shell 1 rear end face, one deck waterproof ventilated membrane 7 is provided with inside speaker housings 1, be arranged at outside sounder circuit plate, the side of shell 1 is also provided with indicator light, upper surface of outer cover is provided with and buckles 8, shell 1 is also provided with compass 9.
The utility model provides a kind of outdoor portable loud speaker, because the temperature of open air is higher, structure utilizes the fin of ambient envelope dispel the heat, prevents the aging serious phenomenon that loud speaker high temperature causes; It is fixing that the structure of vacuum cup makes that loud speaker can be random, adds stability and the adsorptivity of loud speaker; Rotating mechanism the music communication direction that can regulate loud speaker is set; What buckle relates to the portability being more conducive to loud speaker; The design of compass makes can confirm that orientation is not easy to get lost during outdoor use.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technology people of this area should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
