Abstract

A novel sound gathering device mainly includes a case body, a primary source of sound and a cambered baffle-board. The utility model is characterized in that the cambered baffle-board is utilized to transmit sound wave at a certain angle to control the transmitting direction and the spreading range of the sound wave after the primary source of sound emits the sound wave and the baffle-board gathers the sound wave, thereby avoiding the mutual interference by the sound wave emitted by different source of sound, or preventing from spreading to other range.

Description

Novel collection mixer

Technical field

The utility model relates to a kind of novel collection mixer, and the sound wave that particularly a kind of nationality is launched the keynote source by the arc reflecting plate focuses on and is confined to certain scope and reflects, and sound wave is unlikely is diffused into unwanted scope, with the novel collection mixer that avoids interference.

Background technology

General box-type loud speaker commonly used, shown in Figure 1A, be that nationality is launched sound waves also through after the resonance of resonance part 110 by the keynote source 200 that is located on the casing 100, transmit outside casing 100 via keynote source 200 again, shown in Figure 1B, directly toward the casing 100 outer sound wave S1 (S2) that transmitted, is outwards to disperse with coniform by main sound box 200.

Please refer to Fig. 1 C, when adjacent loud speaker respectively sends the sound wave S1 (S2) that outwards disperses certainly, the diffusion of coniform sound wave S1 and S2, add peripheral reflection and be casually arranged with the situation that is produced, form a large-scale sound field, very likely produce between S1 and S2 and disturb this moment, and the hearer hears is through lap over sound wave later and cause listening; Usually this kind situation can cause the difficulty in the identification, and is at a loss as to what to do; Common settling mode utilizes the mode of earphone, and solution can have influence on other people situation; But in public, the use earphone then has the misgivings on the health, with inconvenience that may cause and discomfort.

Summary of the invention

The utility model aims to provide a kind of novel collection mixer, according to the novel collection mixer of this kind of the present utility model, nationality arc reflecting plate, the sound wave that the keynote source is sent out produces the sound field of specific region property with focusing, make different to listen sound that the hearer can hear separately that different keynotes source is sent and unlikely interfering with each other.

Nationality is by the device of the reflecting plate of arc, but feasible sound wave nationality of sending out is reflexed to sound wave in the particular range by the focusing effect of curved surface, the sound wave that can utilize the material of reflecting curved surface that the keynote source is sent out simultaneously stops, makes the unlikely penetration plate of sound wave cause the interference of sound wave scattering.

The sound wave that the novel collection mixer of this kind of the present utility model, nationality are generated by the keynote source can effectively be controlled advancing and range of scatter of sound wave via the reflection of arc reflecting plate, makes to listen that the hearer is unlikely to be difficult to identification.

Embodiment

The body structure of collection mixer of the present utility model shown in Fig. 2 A, mainly is made up of casing 1, keynote source 2, arc reflecting plate 3.

Fig. 2 B is the structure sectional view of novel collection mixer of the present utility model: shown in figure, can find out that reflecting plate 3 is to be formed at casing 1 surface, be arc shape, be located at the rear in keynote source 2, and its focus C drops on outside the casing 1 to outdiffusion, and the pronunciation direction in keynote source 2 is a face reflecting plate 3, make its sound wave that sends out bump against reflecting plate 3 earlier thus, again outside reflecting plate 3 reflects casing 1, and, the design of this reflecting plate 3 is the sound wave that send in keynote source 2 outwards to be transmitted with the type of focusing.

Please refer to Fig. 2 C, this figure is depicted as the autonomous source of sound of sound wave and sends, and the schematic diagram that sends after reflecting plate focuses on and reflects; Shown in figure, keynote source 2 is positioned at the focus C place of arc reflecting plate 3, and in the face of arc reflecting plate 3; Sound wave is launched towards arc reflecting plate 3 by keynote source 2; Because the physical property of the focusing that arc reflecting plate 3 is produced makes sound wave S1 (S2) to reflect abreast; Because by the sound wave S1 that reflecting plate is launched, S2 is parallel, makes sound wave S1, S2 are controlled in a certain particular range, unlikely other scope that diffuses to is shown in Fig. 2 D.

Fig. 2 E is the second embodiment diagrammatic sketch of the novel collection mixer of the utility model; Shown in this figure, visible arc reflecting plate 3 is to be suspended on the ceiling, and downwards in the face of ground, sound wave S1 (S2) is upwards launched in keynote source 2, and the user is positioned at the arc reflecting plate 3 times; When the 2 emission sound wave S1 (S2) of keynote source, arc reflecting plate 3 can send the user downwards to sound wave S1 (S2); Again, because the direction that arc reflecting plate 3 may command sound wave S1 transmit, with the scope that transmits, the sound wave that therefore can allow nigh other user not transmitted by arc reflecting plate 3 disturbs.

Need Chen Mingzhe, the above is the preferable specific embodiment of the utility model, as if the change of being done according to the utility model conception, the function of its generation, when not exceeding specification and the graphic spirit that is contained yet, all should in scope of the present utility model, close and give Chen Ming.

Claims

1, a kind of novel collection mixer mainly comprises: hollow box body, keynote source and reflecting plate; It is characterized in that: reflecting plate system is formed at tank surface, is the arc shape to outdiffusion, and is positioned at rear, keynote source, and its focus also is positioned at outside the casing; This keynote source is positioned on the focus of reflecting plate, and its sound wave direction of transfer system is in the face of reflecting plate; Provide with this, the sound wave that the keynote source sends out strikes reflecting plate earlier, and is external through the baffle reflection outlet again, and outwards transmits in the mode that focuses on, and reaches the transmission direction and the range of scatter of control sound wave, and the sound wave in different keynotes source can not interfered with each other.

2, novel collection mixer according to claim 1; It is characterized in that: reflecting plate system is made with reflecting material.
