Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Refering to attached drawing 1- attached drawing 10, a kind of physics public address set is used for mobile phone 1, and mobile phone 1 is equipped with speaker voice giving hole
10, which further includes the speaker 2 that amplifies, and the speaker 2 that amplifies is additionally provided with air cavity 20, air cavity 20 divide for into
Sound cavity 201 and out sound cavity 202, into 201 first end of sound cavity be into sound mouth 23, it is tight into sound mouth 23 and speaker voice giving hole 10
Closely connected conjunction, 202 one end of sound cavity is connect with the second end into sound cavity 201 out, and the other end extends and penetrates in the speaker 2 that amplifies
One outer wall and the place of penetrating are sound mouth 24, into being equipped with aditus laryngis 230, sound mouth between the first end and second end of sound cavity 201
24 area is greater than the area of aditus laryngis 230.
Specifically, the speaker 2 that amplifies is equipped with 10 place of fitting closely of speaker voice giving hole into sound mouth 23, speaker voice giving
The sound that hole 10 is played out into sound mouth 23 from entering and propagate to from sound mouth 24 along air cavity 20, then from sound mouth 24
Place amplifies sending, realizes the function of the broadcast sound volume and result of broadcast that improve 1 loudspeaker of mobile phone.Simultaneously as horn is utilized
The principle to amplify, which is not necessarily to power supply power supply, and can realize amplifying for the device anywhere or anytime
Function.
Further, for the ease of the molding in air chamber road 20 in actual production, the speaker 2 that amplifies includes fixed case 21 and chamber
Road column 22 is arranged on fixed case 21 into sound mouth 23 and into sound cavity 201, cylindrical hole 210, cavity is additionally provided on fixed case 21
