CN201957108U - Horn installing structure on communication terminal - Google Patents

Abstract

The utility model discloses a horn installing structure on a communication terminal, which is arranged in a housing of the communication terminal and comprises a resonant cavity for installing a horn, wherein a horn opening of the horn is outward, a sound transferring hole is arranged opposite to the horn, and the resonant cavity is a sealing cavity which is arranged at one side in the housing of the communication terminal and separated from other parts in the housing of the communication terminal by using a baffle plate. In the technical scheme of the utility model, because the horn is arranged in the larger sealing resonant cavity, the sound effect of hands free use of the communication terminal is greatly improved.

Description

Loudspeaker mounting structure on a kind of communication terminal

Technical field

What the utility model related to that phone or other communication terminal use when hands-free the use coughs particularly a kind of structure that loudspeaker are installed.

Background technology

At present, phone or other communication terminal also have a kind of hands-free way except listen the other side's sound with receiver, at this moment, sound is to play by the loudspeaker that phone or communication terminal carry, still, and when phone or other communication terminal are exempted from the load use at present, usually utter long and high-pitched sounds, fundamentally just can not use hand-free function this moment, sometimes, though do not utter long and high-pitched sounds, but audio distortions is very serious, and speech quality is poor.

Summary of the invention

In order to solve at present, during the hands-free use of phone or other communication terminal, the deficiency that audio distortions is serious, the utility model provide the mounting structure of the loudspeaker on a kind of communication terminal, can eliminate the deficiency of communication terminal loudspeaker audio distortions when hands-free substantially by this structure.

The utility model for the technical scheme that realizes its technical purpose and adopt is: the loudspeaker mounting structure on a kind of communication terminal, be arranged in the casing of communication terminal, comprise the resonant cavity that loudspeaker are installed, the horn mouth of described loudspeaker is outside, be provided with acoustic hole on the horn mouth opposite, described resonant cavity is an annular seal space, is arranged on the side in the communication terminal housing, separates by the other parts in a dividing plate and the communication terminal housing.

Concrete, in the loudspeaker mounting structure on the above-mentioned communication terminal: described dividing plate comprises and upper spacer that links to each other with described communication terminal housing top and the lower clapboard that links to each other with described communication terminal lower housing portion at upper spacer and lower clapboard junction seal washer is set.

In the technical solution of the utility model,, improved the sound effect of the hands-free use of communication terminal greatly because loudspeaker are installed in the resonant cavity of a bigger sealing.

Below in conjunction with the drawings and specific embodiments the utility model is illustrated in more detail.

Description of drawings

Accompanying drawing 1 is the utility model embodiment 1 user mode schematic diagram.

Accompanying drawing 2 is figure A-A sectional views.

Among the figure: 1, communication terminal, 3, acoustic hole, 4, loudspeaker, 5, upper shell, 6, lower house, 8, resonant cavity, 9, packing ring, 10, upper spacer, 11, lower clapboard.

Embodiment:

As depicted in figs. 1 and 2, present embodiment is a kind of structure that loudspeaker are installed in phone or other communication terminal, and by using this structure, during the hands-free use of phone or other communication terminal, audio distortions is little, will be better if mix high-quality loudspeaker effect.

As shown in Figure 2, this structure comprises a resonant cavity 8 that has occupied a big chunk space below the housing that hangs handle in communication terminal 1 housing, loudspeaker 4 just are installed in the inside of resonant cavity 8, horn mouth is outside, in the relative position of horn mouth acoustic hole 3 is set, the space of resonant cavity 8 is enough big, take the space in the communication terminal housing possibly, as shown in Figure 2, this resonant cavity surrounds by upper shell 5 and lower house 6 and with the upper spacer 10 of upper shell one with the lower clapboard 11 of lower house one, also is provided with seal washer 9 in last lower clapboard contact position in order to guarantee sealing effectiveness.

Claims (2)

1. the loudspeaker mounting structure on the communication terminal, be arranged in the casing of communication terminal, it is characterized in that: comprise the resonant cavity (8) that loudspeaker (4) are installed, the horn mouth of described loudspeaker (4) is outside, be provided with acoustic hole (3) on the horn mouth opposite, described resonant cavity (8) is an annular seal space, is arranged on the side in communication terminal (1) housing, separates by the other parts in a dividing plate and the communication terminal housing.

2. the loudspeaker mounting structure on the communication terminal according to claim 1, it is characterized in that: described dividing plate comprises and upper spacer (10) that links to each other with described communication terminal housing top and the lower clapboard (11) that links to each other with described communication terminal lower housing portion at upper spacer (10) and lower clapboard (11) junction seal washer (9) is set.
