Technical Field
[0001] The utility model relates to the technical field of multimedia equipment, in particular to an audio amplifier suitable for a multimedia hall. Background Art
[0002] Since the internal environment of a multimedia hall is very large, it is difficult for the volume of a certain person's speech to be heard by everyone present during a meeting. Therefore, a loudspeaker is available on the market, which contains a microphone and a loudspeaker. The speech is transmitted through the microphone to the loudspeakers of other devices for playback. Compared with the traditional method of directly using large audio loudspeakers, it has the effects of reducing noise, stabilizing and clarifying the sound, and having a low unit cost. It is more practical for multimedia halls used for multi-person meetings.
[0003] In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: however, in order to allow users to place more meeting materials during the meeting, the conference table in the multimedia conference hall will have a relatively wide desktop. The conference participants are at one end of the table, and the desktop near their front is reserved for placing meeting materials. In order not to affect the placement of the materials, the sound amplification microphone device will be placed at the other end of the table, which will result in a large distance between the conference participants and the sound amplification microphone. When the conference participants need to answer questions or ask questions, the distance for their voices to be transmitted to the microphone will be long, resulting in poor sound reception. In this case, the conference participants need to hold the device in front of them to speak, but in actual situations, since there are many items on the desktop (materials, water cups, utensils, etc.), when moving the items, the items can easily touch the sound reception microphone on the desktop, causing the device to fall and generate noise, and it is impossible to put the equipment back to the same position every time after not using it, which will indirectly make the placement messy and affect the visual experience.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, a sound amplifier suitable for a multimedia hall comprises a speaker 1, a base 2 is arranged below the speaker 1, a loudspeaker 13 is arranged on the front side of the speaker 1, a gooseneck microphone 11 is arranged on one end of the rear side of the speaker 1, and a plurality of joints 12 are arranged on the other end of the rear side of the speaker 1, feet 14 are arranged at the four corners of the bottom of the speaker 1, a magnetic sheet 15 is arranged at the bottom of the feet 14, foot grooves 23 are cut at the four corners inside the base 2, a magnetic sheet 2 25 is arranged at the bottom end of the foot grooves 23, and traceless double-sided tape 21 is adhered to both ends of the bottom of the base 2.
[0022] Specifically, the outer diameter of the bottom of the speaker 1 matches the inner size of the base 2, and the bottom of the speaker 1 is inserted into the base 2, the base foot 14 and the magnetic piece 15 are respectively inserted into the foot groove 23, and the magnetic piece 15 is magnetically connected to the magnetic piece 2 25, respectively, which can limit the speaker 1 inserted into the base 2.
[0023] Specifically, both sides of the base 2 are provided with inclined grooves 22 , so that the speaker 1 can be conveniently and successfully inserted into the base 2 of matching size within a certain position deviation range.
[0024] Specifically, the base 2 is provided with an outward expansion groove 24 at the front side of the top end of the foot groove 23 to guide the base 14 and the magnetic sheet 15 when they are moved into the foot groove 23 .
[0025] Specifically, a rear baffle 3 is fixed to the rear end of the base 2 to stop the speaker 1 from moving.
[0026] Specifically, buckle grooves 16 are formed on both side walls of the speaker 1 to facilitate holding the speaker 1 by hand.
[0027] Working principle: When you need to speak, hold the buckle slot 16 with your hand and pull it upward. After the pulling force causes the magnetic piece 15 to break the magnetic connection with the magnetic piece 25, the speaker 1 can be pulled out from the base 2 so that the participant can take it in front of him to speak. When the speech is over, insert the speaker 1 into the base 2. When inserted, the four feet 14 at the bottom of the speaker 1 are divided into two on the right side close to the rear baffle 3 and two on the left side away from the rear baffle 3, and the four foot slots 23 in the base 2 are also divided into two on the right side close to the rear baffle 3 and two on the right side away from the rear baffle 3. The two feet 14 on the right side need to be It is located between the left foot groove 23 and the right foot groove 23, and slides it toward the position of the rear baffle 3. During the movement, the bottom foot 14 and the magnetic sheet 1 15 can be guided by the outward expansion groove 24, so that the bottom foot 14 and the magnetic sheet 1 15 can accurately enter the foot groove 23. After entering the foot groove 23, the end of the lecturer 1 will contact the rear baffle 3, which has a positioning effect of stopping the movement. After the bottom foot 14 is inserted into the foot groove 23, the lecturer 1 can be limited by the magnetic attraction of the magnetic sheet 1 15 and the magnetic sheet 2 25, and the bonding of the traceless double-sided tape 21 to the desktop can enable the base 2 to stably limit the lecturer 1.
