Abstract
The utility model provides electric equipment with a built-in microphone, which comprises a panel, wherein, a talk hole is formed on the panel, the electric equipment is provided with a cavity accommodating the microphone, the talk hole is communicated with the cavity, a sound receiving head is arranged at the head part of the microphone, the sound receiving head corresponds in position to the talk hole, a sound gathering chamber extending towards the sound receiving head is arranged along the panel, and the sound gathering chamber is positioned inside the cavity accommodating the microphone and communicated with the talk hole. Due to the location of the sound gathering chamber, outside sounds entering the talk hole are collected in the sound gathering chamber so as to prevent the sounds from spreading, before being transferred to the sound receiving head, thereby improving the transfer quality of the sounds.
Description
Technical field
The utility model belongs to appliance field, relates in particular to a kind of electric equipment with built-in microphone.
Background technology
People use for convenience, some electric equipments, and for example phone, laptop computer, DVD etc. are provided with built-in microphone, can reduce the use of external data line like this.But existing microphone directly is arranged at the below, conversation hole that is positioned on the electric equipment panel, and sound directly imports microphone into from the conversation hole, does not pass through any processing, and sound spreads easily, and the sound of output is very faint.In addition, the built-in microphone of electric equipment directly is connected with panel, its inner noise that produces easily passes to microphone when using electric equipment, thereby make the microphone noise big, conversation unsharp problem, especially electric equipment occur as the vehicle-carrying DVD, because the noise that vehicle interior is made is a lot, if its built-in microphone directly is connected with panel, the microphone noise can be very big, and unsharp problem of conversing will be more serious also.
The utility model content
The purpose of this utility model is to provide a kind of electric equipment with built-in microphone, is intended to solve existing electric equipment built-in microphone sound and spreads the problem that the sound of output is very faint easily.
The utility model is achieved in that
A kind of electric equipment with built-in microphone, electric equipment with built-in microphone, comprise panel, panel is provided with the conversation hole, and electric equipment is provided with the cavity of ccontaining microphone, the conversation hole is connected with cavity, the microphone head has the sound of being subjected to head, is subjected to the sound head corresponding with the conversation hole site, along this panel, be provided with to the poly-operatic tunes that extended by sound head direction, the poly-operatic tunes is positioned at the cavity of ccontaining microphone and is connected with the conversation hole.
Compared with prior art, technique scheme since the conversation hole be subjected to be provided with the poly-operatic tunes that is communicated with the hole of conversing between the sound head, external voice enters the back earlier through the poly-operatic tunes by the conversation hole, sound is difficult for diffusion, but send the microphone head after accumulating in here again to be subjected to the sound head, can improve the delivery quality of sound like this.
Description of drawings
The structural representation of the embodiment that Fig. 1 the utility model provides;
Fig. 2 is the cross-sectional schematic along A-A line among Fig. 1.
Fig. 3 is a B place structural representation among Fig. 2.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of and existing electric equipment with built-in microphone to compare, external voice enters the back by the conversation hole and is difficult for diffusion, can improve the electric equipment with built-in microphone of the delivery quality of sound, for this reason, the electric equipment of the utility model embodiment with built-in microphone, the conversation hole be subjected to be provided with the poly-operatic tunes that is communicated with the hole of conversing between the sound head.
Particularly, this instructions is that example illustrates the utility model with the DVD with built-in microphone, and other has the electric equipment of same structure, also in protection domain of the present utility model.
Fig. 1, Fig. 2 and Fig. 3 have shown a kind of DVD with built-in microphone, comprise panel 1, panel is provided with conversation hole 2, and electric equipment is provided with the cavity 8 of ccontaining microphone 3, and conversation hole 2 is connected with cavity 8, microphone 3 heads have the sound of being subjected to head 31, be subjected to sound head 31 corresponding,, be provided with to the poly-operatic tunes 4 that extended by sound head 31 directions along this panel 1 with conversation 2 positions, hole, the poly-operatic tunes 4 is positioned at the cavity 8 of ccontaining microphone 3, and is connected with conversation hole 2.
Like this, external voice enters the back earlier through the poly-operatic tunes 4 by conversation hole 2, and sound is difficult for diffusion, but send microphone 2 heads after accumulating in here again to be subjected to sound head 31, can improve the delivery quality of sound like this.
Further, in the present embodiment, be with barney 6 on the microphone 3, be exposed to outside the barney 6 by sound head 31.Barney can select common sound-proof material to make, for example silica gel sheath.Like this, the inner noise that produces of DVD is difficult for passing to microphone 3, has lowered the interference of consequent noise to microphone 3, and bigger from the noise of DVD inside for vehicle-carrying DVD, effect is obvious especially.
Further, in the present embodiment, on panel 2, also be provided with shockproof chamber 5, can further lower by of the interference of the inner noise that produces of DVD to microphone 3 around the poly-operatic tunes 4.For improving anti-interference effect, extend in panel 2 in shockproof chamber 5, is provided with gap (among the figure not label) between its chamber wall (among the figure not label) and the barney 31.
Further, in the present embodiment, electric equipment is provided with pcb board 7, and pcb board 7 is located in the cavity 8 of ccontaining microphone 3, and microphone 3 is fixed on this PCB version 7 for the microphone of band bluetooth.Can reduce the use of data line like this.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
