Description

Technical Field

[0001] The utility model belongs to the technical field of audio, and in particular relates to a waterproof and dustproof sound box. Background Art

[0002] With the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing, and the sound system has been continuously improved and perfected to meet people's needs, from meeting the needs of live sound reinforcement for concerts with tens of thousands of people to meeting the needs of playing musical instruments and singing karaoke at home.

[0003] However, existing speakers generally do not have a waterproof function, so the charging port is exposed and directly in contact with the external environment. This will cause dust to accumulate at the charging port after long-term use, affecting the normal use of the speaker. When charging the speaker in a humid environment, the exposed charging port will also increase the danger to the user. For this reason, we propose a waterproof and dustproof speaker to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof and dustproof speaker box to solve the problems existing in the background technology.

[0007] The protective component includes a mounting post, which is symmetrically installed on the left and right inner walls of the charging port. A baffle is rotatably installed on the outside of each mounting post, and mounting grooves are symmetrically provided at the left and right ends of each baffle. A torsion spring wrapped around the outside of the mounting post is installed inside each mounting groove, and one end of the torsion spring is fixedly connected to the charging port, and the other end is fixedly connected to the baffle. A semicircular groove is provided at the opposite end of each baffle, and a rotating groove is provided at the rear end of the baffle located on the upper side, and a connecting block is hinged inside the rotating groove, and a circular plate matching the semicircular groove is fixedly installed at the lower end of the connecting block.

[0008] The mounting post facilitates the installation of the baffle and allows the baffle to rotate on its outer side. The baffle can isolate the charging port from the external environment, making it difficult for rain and dust to enter the charging port. The installation groove facilitates the installation of the torsion spring. When the torsion spring is in a natural rotation state, the baffle is in a vertical state. When the baffle tilts outward or inward, the torsion spring will provide a torsional torque to return the baffle to a vertical state. The semicircular groove is convenient for the placement of the charging cable, so that when the audio body is in the charging state, the charging cable will not affect the sealing of the charging port. The rotation groove facilitates the installation of the connecting block, and the connecting block facilitates the installation of the circular plate. The circular plate matches the semicircular groove, so that the inside of the charging port remains sealed.

[0009] A sealing strip is fixedly installed at one opposite end of each baffle, and the sealing strip can prevent moisture and dust from entering the interior of the charging port.

[0010] A magnet bar is fixedly installed on the outer side of the circular plate, and an iron bar is fixedly installed on the inner wall of the semicircular groove located at the lower side. The magnet bar cooperates with the sticker strip to increase the stability between the circular plate and the semicircular groove.

[0011] A rain shield frame wrapped around the outside of the charging port is fixedly installed at the rear end of the audio body, and the rain shield frame can prevent moisture from entering the charging port along the audio body.

[0012] Buckle grooves are symmetrically provided at the left and right ends of the sound body, and the buckle grooves are convenient for staff to move the sound body.

[0013] In the utility model, through the mutual cooperation between the baffle, the mounting groove, the torsion spring, the semicircular groove and the circular plate, the charging port of the speaker body is kept in a closed state during use, thereby preventing moisture and dust from entering and affecting the normal use of the speaker body, and reducing the risk of use during charging.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Embodiment 1:

[0024] like Figure 1-Figure 5 As shown, a waterproof and dustproof speaker includes a speaker body 100, a charging port 101 is provided at the lower side of the rear end of the speaker body 100, and a protective component is provided at the front end of the charging port 101;

[0025] The protection component includes a mounting column 200, which is symmetrically mounted on the left and right inner walls of the charging port 101. A baffle 201 is rotatably mounted on the outside of each mounting column 200. Each baffle 201 has a mounting groove 202 symmetrically opened on both ends of the left and right ends. A torsion spring 203 wound around the outside of the mounting column 200 is installed inside each mounting groove 202, and one end of the torsion spring 203 is fixedly connected to the charging port 101, and the other end is fixedly connected to the baffle 201. A semicircular groove 204 is opened at the opposite end of each baffle 201, and a rotating groove 205 is opened at the rear end of the baffle 201 located on the upper side. A connecting block 206 is hinged inside the rotating groove 205, and a circular plate 207 matching the semicircular groove 204 is fixedly installed at the lower end of the connecting block 206;

[0026] A sealing strip 300 is fixedly mounted on the opposite end of each baffle 210;

[0027] A magnet bar is fixedly mounted on the outer side of the circular plate 207, and an iron bar 301 is fixedly mounted on the inner wall of the semicircular groove 204 at the lower side;

[0028] A rain shield frame 302 wrapped around the outside of the charging port 101 is fixedly installed at the rear end of the audio body 100;

[0029] Buckle grooves 303 are symmetrically provided at the left and right ends of the speaker body 100;

[0030] The audio body 100 is used to play music, and the charging port 101 is used to charge the audio body 100. The mounting column 200 facilitates the installation of the baffle 201, and at the same time allows the baffle 201 to rotate on its outer side. The baffle 201 can isolate the charging port 101 from the external environment, so that rain and dust are not easy to enter the charging port 101. The installation groove 202 is convenient for the installation of the torsion spring 203. When the torsion spring 203 is in a natural rotation state, the baffle 201 is in a vertical state. When the baffle 201 tilts outward or inward, the torsion spring 203 will provide a torsional torque to return the baffle 201 to a vertical state. The semicircular groove 204 is convenient for the placement of the charging cable, so that when the audio body 100 is in a charging state, the charging cable will not affect the sealing of the charging port 101. The rotation groove 205 facilitates the installation of the connecting block 206, and the connecting block 206 facilitates the installation of the circular plate 207. The circular plate 207 matches the semicircular groove 204, so that the inside of the charging port 101 remains sealed.

[0031] The sealing strip 300 can prevent moisture and dust from entering the charging port 101. The magnet strip and the sticker strip 302 cooperate with each other to increase the stability between the circular plate 207 and the semicircular groove 204. The rain shield frame 302 can prevent moisture from entering the charging port 101 along the speaker body 100. The buckle groove 303 facilitates the staff to move the speaker body 100.

[0032] Working principle of this embodiment: when the staff aligns the charging plug with the charging port 101 and inserts it, the baffle 201 is pushed into the charging port 101 by the charging plug. At this time, after the charging plug and the charging port 101 are docked, the baffle 201 is reset around the mounting column 200 under the action of the torsion spring 203. At the same time, the circular plate 207 inside the semicircular groove 204 is lifted up by the power cord, so that the power cord and the semicircular groove 204 are tightly combined, so that the charging port 101 remains sealed, preventing moisture and dust from entering and affecting the normal use of the audio body 100, and also reducing the use risk during the charging process;

[0033] In this embodiment, through the mutual cooperation between the baffle 201, the mounting groove 202, the torsion spring 203, the semicircular groove 204 and the circular plate 207, the charging port 101 of the speaker body 100 is always in a closed state during use, preventing moisture and dust from entering and affecting the normal use of the speaker body 100, and also reducing the risk of use during charging.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
