The utility model provides a mobile communication terminal, its position department through at neighbouring receiver sets up one and provides the first speaker that the low frequency supplyed at the receiver during operation to showing and promoting the tone quality of the low frequency sound sound that sent under the earphone mode at the terminal.

Description

Communication terminal
[technical field]
The utility model relates to a kind of communicating terminal, particularly relates to a kind of communication terminal providing low frequency to supplement when receiver works.
[background technology]
As everyone knows, comprise microphone device in mobile phone, in general, include two kinds of microphone devices, one is referred to as receiver (also referred to as receiver), and another kind is referred to as loud speaker (being commonly called as loudspeaker).Receiver is mainly used in " handset mode ", and loud speaker is generally used for " speaker mode ", also claims " hands-free mode ".Under " handset mode ", user needs to be pressed close to by ear on earpiece limit, clearly could hear the sound sent in receiver.Receiver has best acoustic response acoustically needing to be designed to have with people's ear during coupling." handset mode " can reach better privacy.Under " speaker mode ", receiver does not work, speaker operation.With under equidistant, the sound that loud speaker sends is more much bigger than receiver, and therefore user is without the need to pressing close to mobile phone by ear, just can hear sound." speaker mode " can be used for playing music, user is not easy to mobile phone to press close to the situations such as ear.
Traditional, receiver is dynamic-circular electroacoustic device.The device of this type often can realize reasonable acoustic efficiency, namely good choacoustic frequency response.Wherein for comparatively low-frequency range, as the frequency range of below 200Hz, its acoustic response also has the needs promoted further, and this is necessary for the high definition call obtaining more high bandwidth is experienced.Unconventional, receiver is ceramic-type device, and this ceramic-type device can be independently microphone device, and it also can be to drive mobile phone screen vibration sounding as just driver.For the latter, mobile phone no longer needs to output acoustic aperture in front, which increases waterproof ability and the aesthetics of mobile phone.But when receiver is ceramic-type device, (moving-coil type receiver compared to traditional) its LF-response is not often fine, this feels to be exactly sound " partially point " or " bass is full not " what acoustically bring, and this have impact on Consumer's Experience.
[utility model content]
The purpose of this utility model is to provide a kind of communication terminal, and it is for the bad technical problem of the tonequality of the low-frequency range sound solving current communication terminal and sent by receiver under its handset mode.
In order to solve the problems of the technologies described above, the utility model provides a kind of communication terminal, it receiving space comprising shell and formed by this shell, is provided with a receiver and is close to this receiver and provides the first loud speaker that low frequency supplements when this receiver works in this receiving space.
Preferably, described shell is provided with phonate hole, and described first loud speaker is spoken by this phonate hole.
Preferably, described shell also comprises a display screen, and the direction of speaking of described phonate hole is parallel to this display screen.
Preferably, described receiver is piezoelectric vibrator, and this piezoelectric vibrator drives described shell sounding.
Preferably, described first loud speaker is long stroke loud speaker, and the acoustic radiating direction of this long stroke loud speaker is parallel to described display screen.
Preferably, this terminal also comprises one away from the second loud speaker of described receiver.
The beneficial effects of the utility model are: the communication terminal that the utility model provides, it by arranging first loud speaker providing low frequency to supplement when receiver works in the position of contiguous receiver, thus significantly improves the tonequality of the low-frequency sound that described terminal sends under handset mode.
[accompanying drawing explanation]
Fig. 1 is the schematic perspective view of the utility model communication terminal;
Fig. 2 is the cross-sectional schematic of communication terminal shown in Fig. 1.
[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As illustrated in fig. 1 and 2, the utility model provides a kind of communication terminal 1, in order to clearly demonstrate this communication terminal 1, is specifically described for a kind of mobile phone now.The receiving space 100 that described communication terminal 1 comprises shell 10 and formed by this shell 10, is provided with a receiver 11 and is close to this receiver 11 and provides the first loud speaker 12 that low frequency supplements when this receiver 11 works in this receiving space 100.
Mobile phone generally all arranges a receiver 11 and is used for the sounding when handset mode, and in order to make sound can be heard by clear, the high frequency performance of general receiver 11 is better than low frequency performance.Just there is a defect in this, when playing low frequency voice signal, such as frequency is at the voice signal of below 200HZ, and the sound that receiver 11 sends is just clear not, makes the tonequality of the low-frequency sound under handset mode be subject to appreciable impact.Therefore, the utility model, after the position of contiguous described receiver 11 arranges first loud speaker 12 providing low frequency to supplement when this receiver 11 works, can promote the tonequality of the low-frequency sound that this terminal 1 sends under handset mode greatly.
Described shell 10 comprises bonnet 102 that protecgulum 101 and this protecgulum 101 relative spacing arrange, is arranged on the frame 103 between described protecgulum 101 and bonnet 102 and the display screen 104 with this protecgulum 101 assembly.Described frame 103 and described bonnet 102 can be wholely set, and also can be independently structure separately, i.e. split setting.
Described shell 10 is provided with phonate hole 105, and described first loud speaker 12 is by this phonate hole 105 entrant sound, and the direction of speaking of described phonate hole 105 is parallel to this display screen 104, and preferably, described phonate hole 105 is arranged on described frame 103.Present mobile phone is generally elongated, and therefore, described frame 103 comprises long margin frame 1030 and the short frame 1031 being connected described long margin frame 1030, and described phonate hole 105 is arranged on this long margin frame 1030 or on short frame 1031.
The utility model preferred embodiment in, described receiver 11 is piezoelectric vibrator, it drives described shell 10 vibration sounding, and therefore, described receiver 11 can drive described protecgulum 101, bonnet 102, frame 103 and any one vibration sounding of display screen 104.Like this, when described receiver 11 is piezoelectric vibrator, the shell 10 just noting be used in described communication terminal 1 is offered extra acoustic aperture to speak for described receiver 11, thus greatly promote the water proof and dust proof performance of described terminal 1.
Described first loud speaker 12 preferably adopts the long stroke loud speaker with good low frequency performance, and the acoustic radiating direction of this long stroke loud speaker is parallel to described display screen 104, significantly can provide the tonequality of described communication terminal 1 under handset mode like this.In fact, this terminal 1 also comprises one away from the second loud speaker 13 of described receiver 11, jointly realizes stereophonic effect by the first loud speaker 12 and the second loud speaker 13.
The communication terminal 1 that the utility model provides, it by arranging first loud speaker 12 providing low frequency to supplement when receiver 11 works in the position of contiguous receiver 11, thus significantly improves the tonequality of the low-frequency sound that described terminal 1 sends under handset mode.
Above-described is only better embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
