Abstract

The utility model mainly aims to solve the problem that a fixed terminal loudspeaker passing out sound directly occupies excessive space and has small sound. Accordingly, one embodiment of the utility model provides a fixed voice terminal, which comprises a loudspeaker positioned inside the terminal. The loudspeaker includes a sound generating part, a front cavity, a rear cavity and a sound passing hole; the front cavity and the rear cavity are respectively coupled with the sound generating part; the rear cavity is used for resonating to sound generated by the sound generating part; the front cavity connected with the sound passing hole is used for guiding the sound to the sound passing hole; and the sound passing hole positioned on the lateral surface of the terminal is used for passing out the sound.

Description

A kind of side goes out the fixedly voice terminal of sound

Technical field

The utility model relates to communication technical field, and especially a kind of side goes out the fixedly voice terminal of sound.

Background technology

Present fixedly voice terminal (comprising that telephone set, conference terminal, fixing radio telephone etc. are placed on the speech communication terminal of desktop) all has loud speaker, is used for jingle bell and hand-free call, mainly is to remind user of incoming call, perhaps is used for hand-free call.

Fig. 1 is a kind of schematic diagram of typical fixed telephone, and the part among the figure in the frame of broken lines promptly is the loud speaker of telephone set, and the phonate hole of this loud speaker is positioned at the below of telephone handle.Present this structural design major defect is to take too much space, because handle has blocked the phonate hole of loud speaker, causes the tinkle of bells less than normal simultaneously.If microphone is placed near the handle in addition,, cause the echo problem of conversation because handle may cause sound reflection to return microphone to the reflex of sound.

The utility model content

The utility model main purpose is to solve fixed terminal just going out the sound loud speaker and take too much space, the problem that sound is little, and for this reason, an embodiment of the present utility model provides a kind of fixedly voice terminal, comprising:

Loud speaker, be positioned at described terminal inner, comprise sounding parts, ante-chamber, back cavity and phonate hole, described ante-chamber and back cavity are coupled with described sounding parts respectively, described back cavity is used for the sound generating sympathetic response of sending with described sounding parts, and described ante-chamber links to each other with described phonate hole, is used for the described sound described phonate hole that leads, described phonate hole is positioned at the side of described terminal, is used for described sound is spread out of.

The scheme of embodiment of the present utility model by the fixing sound of voice terminal is spread out of from the side, it is little to take up room, avoided blocking of handle, can prevent that sound from being caused echo by handle reflected back microphone, utilize fixing voice terminal to be placed on the advantage of desktop simultaneously, because the reflex of desktop, sound sounds that understanding calibration goes out about the big 2dB of sound, promote volume, improved user's experience.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model.

Fig. 2 is the end view of an embodiment of the present utility model, and fixedly the side of voice terminal 100 is provided with phonate hole 105 (in the frame of broken lines), and the sound of loud speaker spreads out of from phonate hole 105.Internal structure as shown in Figure 3, fixedly the sounding parts 110 of the loud speaker of voice terminal are shown in dash area among the figure, its next door has two

cavitys

120 and 130 to be coupled with it respectively, a sealed hollow 120 is called back cavity, its effect is the sound generating sympathetic response that generation part 110 is sent, and improves volume.Another cavity 130 links to each other with phonate hole, is called ante-chamber, and its effect is that described sound guiding phonate hole 105 is spread out of.For the position of sounding parts 110 and back cavity 120, present embodiment is not done qualification.

The scheme of the foregoing description by the fixing sound of voice terminal is spread out of from the side, it is little to take up room, avoided blocking of handle, can prevent that sound from being caused echo by handle reflected back microphone, utilize fixing voice terminal to be placed on the advantage of desktop simultaneously, because the reflex of desktop, sound sounds that understanding calibration goes out about the big 2dB of sound, promote volume, improved user's experience.

As shown in Figure 4, in another embodiment of the present utility model, fixedly voice terminal is provided with two

loud speakers

210 and 230, their phonate holes separately are separately positioned on the fixedly both sides of voice terminal, simultaneously, be provided with played in stereo module 220 in the described terminal, itself and two loud speakers are coupled respectively, and it is stereo to be used to control described two loudspeaker plays.This module can reach stereosonic effect by phase place or the sound intensity level that changes two loud speaker shoos.This embodiment can produce stereosonic effect by means of two loud speakers, and is little because side goes out under the scheme of sound loud speaker phonate hole area occupied, can obtain bigger volume by the reflection of desktop, be convenient to the realization of played in stereo.Certainly, it will be understood by those skilled in the art that the foregoing description is not limited to two loud speakers, also can have three or more loud speakers.

In addition; the technical characterictic that illustrates respectively among each technology, system, device, method and each embodiment that illustrates respectively among the above embodiment can make up; thereby form other the module do not break away within spirit of the present utility model and the principle; method, device, system and technology; the module that these combine according to the record of the utility model embodiment; method, device, system and technology are all within protection range of the present utility model.

Obviously, those skilled in the art should be understood that, above-mentioned each unit of the present utility model or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in the storage device and carry out by calculation element.Perhaps they are made into each circuit module respectively, perhaps a plurality of unit in them or step are made into single circuit module and realize.Like this, the utility model is not restricted to any specific hardware and software combination.

More than being preferred embodiment of the present utility model, is not to be used to limit protection range of the present utility model.All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all be included in the protection range of the present utility model.
