Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A notebook keyboard horn as shown in fig. 1-2, comprising:
the sound cavity shell 1 is used for providing a sound cavity structure for a loudspeaker and is assembled with a notebook;
the electrodynamic loudspeaker is arranged inside the sound cavity shell 1;
the sound cavity shell 1 is of a sheet structure, the thickness of the sound cavity shell 1 is smaller than one centimeter, an extension part 7 is arranged at one end of the sound cavity shell 1, the extension part 7 and a main body of the sound cavity structure form a gap, a concave platform 6 is arranged at the gap, installation and positioning are facilitated through a two-stage limiting structure, and installation space is saved;
and the sound outlet hole is formed in the sound cavity shell 1.
The sound outlet holes are provided with a first sound outlet hole 2 and a second sound outlet hole 3, the first sound outlet hole 2 is arranged on one surface of the sound cavity shell 1, and the second sound outlet hole 3 is arranged on the extension part 7.
Wherein, sound chamber casing 1 is equipped with hole site 4, hole site 4 is used for fixed loudspeaker, hole site 4 is more than or equal to two, at least two hole site 4 is located respectively sound chamber casing 1's long limit both ends.
The shock-absorbing structure is characterized by further comprising a silica gel pad, wherein the silica gel pad is arranged on the hole position 4 and used for shock absorption.
The sound outlet structure comprises a sound outlet hole, and is characterized by further comprising a foam net, wherein the foam net is arranged at the sound outlet hole and covers the sound outlet hole.
The sound cavity comprises a sound cavity shell 1 and a wire connector 5, wherein the wire is arranged at one end of the sound cavity shell 1.
The wire connector comprises a wire connector body and is characterized by further comprising a stranded wire, wherein the stranded wire is connected with the wire connector body 5.
