Face.The key sounding device directs out radiation sound, does not need that the preceding operatic tunes and out acoustic aperture etc. is arranged, therefore not will form acoustics
Acoustic resonator.This makes the sounding effect of the key sounding device, especially high frequency (for example, frequency is 2KHz or more) sounding effect
Well.
In addition, the voice directions of the key sounding device are identical as installation direction, the side of electronic equipment can be arranged on
Portion 12, such as long side wall 21 or short side wall 22.
In addition, the cap portion 13 of the key sounding device has the function of key itself simultaneously.For example, volume adjustment, project
Switching etc..
According to another embodiment of the present disclosure, a kind of electronic equipment is provided.For example, electronic equipment include mobile phone 11,
Tablet computer, laptop, game machine, intercom, television set etc..
As shown in Figure 1-3, the electronic equipment includes shell and above-mentioned key sounding device.Installation is formed on shell
Hole.Elastomeric element 15 is connect with shell.Driver 14 is suspended in mounting hole.It is illustrated by taking mobile phone 11 as an example below.
Mounting hole is provided on the side wall of the center of mobile phone 11.Key sounding device is arranged on the side wall of shell.
The position is not take up the space of the front and back of mobile phone 11, convenient for shielding the integrative design of design and appearance comprehensively.Excitation
Device 14 is suspended in mounting hole.Gap 17 is formed between driver 14 and hole wall, and driver 14 is caused to interfere to avoid hole wall.
In one example, as shown in figure 4, being provided with recessed ring-shaped step knot at the position around mounting hole of shell
Structure 23.Elastomeric element 15 is embedded in annular step structure 23.For example, elastomeric element 15 is cyclic structure, by glue by elastic portion
Part 15 is bonded on the step surface of ring-shaped step structure 23.This setup can be effectively prevented from cap portion 13 and excessively protrude from
Electronic equipment, such as the outer surface of mobile phone 11, so that the appearance of electronic equipment is good.
In addition, ring-shaped step structure 23 can also play the role of positioning, so that the installation of elastomeric element 15 is more accurate.
In one example, as shown in figure 4, driver 14 is electrically connected by FPCB16 with electronic equipment.For example, driver
14 are connected by the control device 20 of FPCB16 and electronic equipment.The electric signal of 14 response control apparatus 20 of driver and shake
It is dynamic.It is connected compared to using signal wire, the durability of FPCB16 is more preferable.
