Description

Technical Field

[0001] The invention relates to a combined speaker structure for sound, belonging to the technical field of speakers. Background Art

[0002] Speakers are modern electro-acoustic components that convert electrical signals into sound. They are also called loudspeakers. Speakers are used in various aspects of audio equipment, such as external amplifier speakers for computers, speakers that play music in squares, etc. The existing speaker structure is generally composed of a rubber elastic ring, a paper cone, a bracket and a magnet. The sound-generating methods of speakers include electromagnetic, inductive, electrostatic, flat, ribbon and horn. The basic principle of the dynamic type comes from Fleming's left-hand rule. If a wire with current is placed perpendicular to the magnetic lines of force between the north and south poles of a magnet, the wire will move due to the interaction between the magnetic lines of force and the current. When a diaphragm is attached to this wire, the diaphragm moves back and forth as the current changes. Currently, more than 90% of cone units are dynamic designs.

[0003] The magnet device and the basin frame at the bottom of the existing speaker are generally fixed with glue. Although the fixation is convenient, when the speaker is installed close to an electrical device with large heat dissipation, the heat will melt the glue, making the magnet device unstable. At the same time, gaps will be generated at the place where the glue falls off, and external water vapor can easily enter, which is also inconvenient for later disassembly. Secondly, there is no water vapor protection structure on the outside of the traditional voice coil, and external moisture can easily enter the voice coil through the basin frame, thereby affecting the movement of the voice coil. Summary of the invention

[0004] The object of the present invention is to provide a combined speaker structure for audio to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] In the above-mentioned combined speaker structure for audio, a paper cone is installed on the top of the basin frame, and a folded edge is provided at the connection between the paper cone and the basin frame. There are many kinds of materials used for the conical diaphragm of the conical paper cone speaker, generally there are two categories: natural fiber and artificial fiber. Natural fibers often use cotton, wood, wool, silk, and artificial fibers use rayon, nylon, and glass fiber. Since the paper cone is the sound radiation device of the speaker, it determines the sound performance of the speaker to a considerable extent. Therefore, no matter which kind of paper cone is used, it is required to be light and rigid, and cannot be deformed due to changes in ambient temperature and humidity. The folding ring is set to ensure the axial movement of the paper cone along the speaker and limit the lateral movement. At the same time, it plays a role in blocking the air circulation before and after the paper cone. In addition to the commonly used paper cone materials, the folding ring also uses plastics, natural rubber, etc., which are bonded to the paper cone through hot pressing.

[0008] In the above-mentioned combined speaker structure for audio, a dust cover is arranged at the center of the top of the paper cone, the paper cone is provided with a spring, and the bottom end of the paper cone is bonded to the center position of the spring.

[0009] In the above-mentioned combined speaker structure for audio, the elastic wave is fixedly installed at the bottom position inside the paper cone, a voice coil is installed at the center of the elastic wave, and the voice coil is placed inside the moisture-proof sleeve. The voice coil is the driving unit of the conical paper cone speaker. It is made of very thin copper wire wound on a paper tube in two layers, generally with dozens of turns, also known as a coil, placed in the magnetic gap formed by the magnetic core column and the magnetic plate. The voice coil is fixed together with the paper cone. When the sound current signal is passed into the voice coil, the vibration of the voice coil drives the vibration of the paper cone.

[0010] In the above-mentioned combined speaker structure for audio, an insertion rod is arranged inside the installation groove, a rotating ring is movably arranged inside the support seat, a lever is arranged on the side of the rotating ring, and one end of the insertion rod is connected to the inner side of the rotating ring.

[0012] In the above-mentioned combined speaker structure for audio, a baffle plate is arranged at the bottom end of the base plate, a baffle groove is opened at the center position of the washer gasket, and the baffle plate is inserted into the interior of the baffle groove, a drainage hole is opened on the outer side of the washer gasket, and the drainage hole is connected to the interior of the baffle groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention provides a combined speaker structure for audio, wherein four groups of mounting blocks fixed on a bottom plate are arranged at the bottom of a basin frame, and when the basin frame is installed on a washer gasket, the basin frame is directly fixed by the mounting blocks, and the mounting blocks enter into the mounting grooves, and then the mounting blocks are limited under the limitation of the insertion rods, and then the installation of the basin frame is completed. With such a structural arrangement, there is no problem of glue falling off at the bottom of the traditional basin frame, and at the same time, the basin frame is simply and efficiently fixed, and is easy to inspect and disassemble. The present application also provides a blocking groove and a blocking plate, which further form a blocking protection at the bottom of the basin frame to prevent external water vapor from entering, and a moisture-proof collar arranged on the outside of the voice coil is used to form a two-layer protection structure. Such a structure can effectively protect the voice coil and prevent the voice coil from being affected by external water vapor. BRIEF DESCRIPTION OF THE DRAWINGS
