Abstract

The utility model discloses a mobile communication device. The mobile communication device comprises a device main body, a front side panel, a device back casing and a receiver, wherein the receiver comprises a piezoelectric ceramic loudspeaker which is installed in space formed by the front side panel and the device back casing and presses against the front side panel for driving the front side panel to vibrate and generate sounds through piezoelectric ceramics. Compared with the prior art, the mobile communication device uses the piezoelectric ceramic loudspeaker for driving the front side panel of the device to generate sounds, so that a user can answer a phone call when user's ears come closer to any position of the front side panel; and at the same time, no receiver holes are needed, and thus the mobile communication device has better dustproof capability and waterproof capability.

Description

A kind of mobile communication equipment
Technical field
The utility model relates to portable electric appts, especially relates to a kind of mobile communication equipment.
Background technology
Existing mobile communication equipment; such as mobile phone, have the smart machine of call function etc.; use based on the maturation of touch technology, for so that mobile phone is more generous, attractive in appearance, conventional keys is abandoned; cell phone appearance often is designed to the structure of almost symmetry; this especially in the environment of dark, can take mobile phone anti-so that the mobile phone upper and lower side is difficult to differentiate often by mistake when receiving calls; needing to rotate 180 degree can normally receive calls, and user experience quality descends.
Simultaneously, traditional mobile communication equipment all needs to offer the receiver hole, and the user receives calls by the receiver hole, but the aspect defectives such as the existence of receiver hole is dustproof, waterproof.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of mobile communication equipment, and it need not to offer the receiver hole, and positive and negative two ends all can normally receive calls.
Technical problem of the present utility model is solved by following technological means:
A kind of mobile communication equipment comprises equipment body, front panel, equipment shell on the back and receiver, wherein:
Described receiver comprises piezoelectric ceramic loudspeaker;
Institute's piezoelectric ceramic loudspeaker is installed in described front panel and the formed space of described equipment shell on the back;
Institute's piezoelectric ceramic loudspeaker and described front panel butt are used for by the described front panel vibrations of Piezoelectric Ceramic sounding.
Preferably, two-end structure is symmetrical up and down for described front panel.
Compared with prior art, mobile communication equipment of the present utility model utilizes the front panel sounding of piezoelectric ceramic loudspeaker driving arrangement, the user only need to be with the optional position of ear near the mobile phone front panel, namely can receive calls, easy to use, simultaneously, owing to do not need to offer the receiver hole, mobile communication equipment of the present utility model has better dustproof, waterproof ability.
Description of drawings
Fig. 1 is the front panel structural representation of mobile communication equipment of the present utility model;
Fig. 2 is the loud speaker of mobile communication equipment of the present utility model and the syndeton schematic diagram of front panel;
Fig. 3 is the right view of Fig. 2.
Embodiment
Preferred embodiment the utility model is described in further detail for the below's contrast accompanying drawing and combination.
A kind of mobile communication equipment comprises equipment body, front panel, equipment shell on the back and receiver.Equipment body is the aggregate of the functions such as mobile communication equipment power supply, communication, data operation processing, for the various functions of mobile communication equipment provide support; Comprise the parts such as touch display screen, cover glass in the front panel, as shown in Figure 1, the front panel 100 of present embodiment is that with the conspicuousness difference of prior art it need not to offer the receiver hole, and symmetrical structure can be adopted in the up and down two ends of front panel 100.
As shown in Figure 2, the receiver of present embodiment adopts piezoelectric ceramic loudspeaker 200, it is installed in front panel 100 and the formed space of equipment shell on the back and is connected with equipment body, the audio signal that the receiving equipment main body sends, piezoelectric ceramic loudspeaker 200 is attached on the front panel 100, it is converted to audio signal by piezoelectric ceramic the vibrations of characteristic frequency, amplitude, and then driving front panel 100 whole vibrations sounding, the user all can hear the sound that piezoelectric speaker 200 sends by front panel 100 with ear near the optional position of front panel 100.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be considered as belonging to protection range of the present utility model.

Claims (3)
