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.
The notebook speaker with sound produced from both sides as shown in fig. 1-2 comprises:
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 less than one centimeter, and one end of the sound cavity shell 1 is provided with an extension part 6;
and 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 and the second sound outlet hole 3 are arranged on two opposite surfaces of the sound cavity shell 1, the second sound outlet hole 3 is arranged on the extension part 6, and the length-width ratio of the second sound outlet hole 3 is more than twice of that of the first sound outlet hole 2.
Wherein, the length direction of the second sound outlet 3 is parallel to the length direction of the sound cavity shell 1.
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.
