Abstract

The utility model relates to a loudspeaking device, in particular to the loudspeaking device of a portable device. The loudspeaking device comprises a support (1), a supporting rod (2) and a pedestal (3). The support (1) is equipped with a groove (4), and the bottom of the groove (4) is equipped with a sound collecting hole (5). The supporting rod (2) is a tubular structure, and the upper part of the supporting rod (2) is communicated with the sound collecting hole (5). The right side of the pedestal (3) is equipped with a sound amplifying hole (7), and a curve-shaped pipeline (6) having a gradually increased thickness is arranged inside the pedestal (3). The thin end of the pipeline (6) is communicated with the lower part of the supporting rod (2), and the thick end of the pipeline (6) is connected with the sound amplifying hole (7). The loudspeaking device of the utility model does not need to add any loudspeaking circuit and loudspeaker to increase the volume and improve the timbre, and is low in cost. The shell can be designed flexibly according to demands, thereby satisfying the requirements of people for appearance and performance simultaneously.

Description

A kind of public address equipment

Technical field

The utility model relates to a kind of public address equipment, relates in particular to a kind of public address equipment of portable equipment.

Background technology

Growing along with electronic communication, portable equipment except typical basic function, also comprises the more function such as game machine, music player, recording as mobile phone, palmtop PC etc.Yet, the broadcasting of these portable equipments adopts earphone or built-in miniature loudspeaker more, wherein earphone only meets individual's appreciation, and boombox power is little, volume is not high, and tonequality is not high, sometimes loud speaker is reached to max volume and also have the noise appearance, usually the user can only improve volume by external loudspeaker arrangement, and this has improved use cost undoubtedly, and makes the power consumption of electronic equipment higher.

The utility model content

The technical problems to be solved in the utility model is, for the defect of prior art, provide a kind of specious, need not power supply, utilize resonance to reach the portable equipment loudspeaker of amplifying effect.

The utility model is achieved through the following technical solutions:

A kind of public address equipment is characterized in that: it comprises support (1), support bar (2) and base (3); Described support (1) is provided with groove (4), and described groove (4) bottom is provided with MIC (5); Described support bar (2) is tubular structure, and top is communicated with MIC (5); Described base (3) front is provided with playback macropore (7), base (3) inside arranges a pipeline of the shaped form by thin chap (6), the taper end of described pipeline (6) is communicated with the bottom of support bar (2), and the butt end of described pipeline (6) is connected with playback macropore (7).

Further, the described groove (4) of stating is for placing portable equipment, and described MIC (5) position is corresponding with the portable equipment loudspeaker position.

Further, it also comprises a housing (8), and it is upper that described housing (8) is arranged on base (3), and described support (1), support bar (2) all are arranged on housing (8) inside.

Further, the shape of stating groove (4) matches with the overall dimension of the portable equipment of putting into.

Further, also be provided with the second support bar (9) between described support (1) and base (3).

The principle that amplifies of the present utility model is as follows: the sound sent when the portable equipment be placed in groove spreads into the shaped form pipeline through MIC, pipeline has reduced sound on the one hand to diffusion everywhere, sound reflects and causes resonance in pipeline on the other hand, make the amplitude of sound wave be superposeed, and continue to propagate along the pipeline of chap gradually, amplitude is significantly stack further, the last sound played back by the playback macropore, volume increases, tonequality improves and has kept the exquisiteness of former sound, makes sound present optimum efficiency.

The beneficial effects of the utility model are: increase volume and improve tonequality without adding any audio-amplifying circuit and loud speaker, and with low cost, and shell flexible design as required, meet people simultaneously to the demand of outward appearance and performance.

Fig. 2 is the utility model overall structure front view;

Fig. 3 is the utility model vertical view.

Embodiment

Below in conjunction with Figure of description, the utility model is described in further details:

As shown in Figure 1, the utility model comprises support 1, support bar 2 and base 3; Described support 1 is provided with groove 4, and described groove 4 bottoms are provided with MIC 5; Described support bar 2 is tubular structure, and top is communicated with MIC 5; Described base 3 fronts are provided with playback macropore 7, and base 3 inside arrange a pipeline of the shaped form by thin chap 6, and the taper end of described pipeline 6 is communicated with the bottom of support bar 2, and the butt end of described pipeline 6 is connected with playback macropore 7.

Described groove 4 is for placing portable equipment, and the shape of groove 4 matches with the overall dimension of the portable equipment of putting into.As shown in Figure 3, described MIC 5 positions are corresponding with the portable equipment loudspeaker position.Its use is for support portable equipment 10, and the sound that portable equipment 10 sends is collected by MIC 5 as far as possible fully.

During use, the sound that portable equipment 10 plays out enters the shaped form pipeline 6 of base from the tubular structure of support bar 2 after being collected by MIC 5, reduced on the one hand the diffusion of sound, sound is through the reflection of tube wall simultaneously, cause resonance, the stack of the amplitude of sound wave, make resonance effect more obvious by the pipe design of thin chap, reaches the effect of voice emplifying at double.Therefore when sound plays back from playback macropore 7, volume increases, and has kept the exquisiteness of former sound, makes sound present optimum efficiency.

In order to make the utility model outward appearance more attractive in appearance, can also design an also housing 8, described housing 8 is arranged on base 3, and described support 1, support bar 2 all are arranged on housing 8 inside.Shell 8 external stylings can ever-changingly be not limited to regular rectangle, circle, trapezoidal etc., also can be designed to cartoon figure, animal etc., make equipment appearance seem more attractive in appearance.

As shown in Figure 2, also being provided with the second support bar 9 between described support 1 and base 3, can be that whole equipment is more firm when the carrying portable equipment.

For the person of ordinary skill of the art, corresponding change and the distortion of other that can make according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of claim of the present utility model.
