Adopt the utility model discloses technical scheme, the sound that the speaker phonate hole sent passes through the outside acoustic of horn form passageway, and horn form passageway can improve electro - acoustic conversion efficiency, has consequently improved the output sound pressure level of mobile terminal speaker.
Description
Technical field
This utility model relates to technical field of communication equipment, particularly relates to a kind of mobile terminal protection set and mobile terminal external member.
Background technology
Along with the continuous progress of science and technology, all kinds of mobile terminal such as mobile phone, panel computer has obtained the development maked rapid progress.As a example by mobile phone, along with improving constantly of user's request, the renewal of the various aspects such as its structure, outward appearance, performance is the most frequent.
Speaker is the microphone device of mobile terminal.Loudspeaker sensitivity embodies the electro-acoustic conversion efficiency of speaker, its refer to loudspeaker input terminal input rated power the signal of telecommunication time distance speaker setpoint distance at produced by sound pressure level.In prior art, on the one hand, the loudspeaker sensitivity of mobile terminal is relatively low, it means that speaker electro-acoustic conversion efficiency relatively low, therefore consuming in the case of certain electrical power, the output sound pressure level of speaker is relatively low；On the other hand, the actual electric power of the speaker of mobile terminal is the least, and this output sound pressure level also resulting in speaker reduces further.
Utility model content
This utility model embodiment provides a kind of mobile terminal protection set and mobile terminal external member, to improve the output sound pressure level of mobile terminal speaker.
The mobile terminal protection set that this utility model embodiment provides; it is provided with horn shape passage in described mobile terminal protection set; the entering tone mouth of described horn shape passage is relative with the speaker voice giving hole site of mobile terminal, and the outlet sound mouth of described horn shape passage is open towards the outside of mobile terminal protection set.
It is also preferred that the left described horn shape passage is bending-like.
Preferably, described mobile terminal protection set includes that diapire and sidewall, the outlet sound mouth of described horn shape passage are positioned at minor face sidewall or the long side wall of mobile terminal protection set
Preferably, between adjacent two walls of described horn shape passage, there is rounding.
Using the technical scheme of this utility model embodiment, the sound that speaker voice giving hole sends passes through the horn outside acoustic of shape passage, and horn shape passage can improve electro-acoustic conversion efficiency, therefore improve the output sound pressure level of mobile terminal speaker.
This utility model embodiment additionally provides a kind of mobile terminal external member, protects set including mobile terminal with according to the mobile terminal described in aforementioned arbitrary technical scheme.
Optionally, described mobile terminal includes mobile phone or panel computer.

Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1; it is provided with horn shape passage 11 in the mobile terminal protection set 10 that this utility model provides; the entering tone mouth 12 of horn shape passage is relative with the position, speaker voice giving hole 14 of mobile terminal, and the outlet sound mouth 13 of horn shape passage is open towards the outside of mobile terminal protection set 10.
Using the technical scheme of this utility model embodiment, the sound that speaker voice giving hole 14 sends passes through the outside acoustic of horn shape passage 11, and horn shape passage 11 can improve electro-acoustic conversion efficiency, therefore improve the output sound pressure level of mobile terminal speaker.
Horn shape passage improves the principle of electro-acoustic conversion efficiency: the vibrating diaphragm of speaker promotes the air operational at the outlet sound mouth of horn shape passage by horn shape passage, the cross section that horn shape passage gradually expands is equivalent to increase the vibrating diaphragm area of speaker, therefore improve the sound radiation impedance of horn shape passage, sound radiation impedance characterizes the sound source ability to working medium radiation acoustic energy, and acoustic energy is proportional with acoustical power, thus improve electro-acoustic conversion efficiency.
As shown in Figures 2 and 3, in preferred embodiment of the present utility model, horn shape passage 11 is in bending-like.Use this technical scheme, horn shape passage longer after can being synthesized, thus further increase electro-acoustic conversion efficiency, improve the output sound pressure level of mobile terminal speaker.
In preferred embodiment of the present utility model, mobile terminal protection set 10 includes that diapire and sidewall, the particular location at the outlet sound mouth place of horn shape passage do not limit, as in figure 2 it is shown, the outlet sound mouth 13 of horn shape passage is positioned at the minor face sidewall of mobile terminal protection set；Or, as it is shown on figure 3, the outlet sound mouth 13 of horn shape passage is positioned at the long side wall of mobile terminal protection set.When the outlet sound mouth 13 of horn shape passage is positioned at the minor face sidewall of mobile terminal protection set 10; the bending hop count of horn shape passage 11 can be reduced on the premise of space availability ratio in raising mobile terminal protection set 10; reduce the bending shape impact on sound transmission; thus further increase electro-acoustic conversion efficiency, improve the output sound pressure level of mobile terminal speaker.
As in figure 2 it is shown, in preferred embodiment of the present utility model, there is rounding between adjacent two walls of horn shape passage.As such, it is possible to make sound propagation in horn shape passage more smooth, the tonequality of the outlet sound mouth output of horn shape passage is more preferable.
To sum up, compared to existing technology, this utility model embodiment is used to improve the output sound pressure level of mobile terminal speaker.
This utility model embodiment additionally provides a kind of mobile terminal external member, and the mobile terminal including mobile terminal and aforementioned arbitrary technical scheme protects set.This mobile terminal external member can improve electro-acoustic conversion efficiency, improves the output sound pressure level of mobile terminal speaker.
The particular type of the mobile terminal that this utility model embodiment provides does not limits, such as, can be the equipment such as mobile phone or panel computer.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
