Description

Technical Field

[0001] The utility model relates to a loudspeaker, in particular to a loudspeaker with a thin structure. Background Art

[0002] With the progress and development of society, speakers are used in more and more areas. The design of old speakers has certain restrictions on the height of the finished product: sufficient space H must be reserved from the speaker's elastic wave to the bottom to avoid the undesirable phenomenon of the outlet elastic wave hitting the bottom. The magnetic circuit assembly is located at the bottom of the basin frame. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to provide a speaker with a thin structure in order to overcome the deficiencies in the prior art.

[0004] The utility model adopts the following technical solution to solve the technical problem: a speaker with a thin structure, comprising a magnetic bowl, wherein the upper part of the magnetic bowl is provided with a connecting sleeve, the middle hole of the connecting sleeve is provided with a voice coil, the outer part of the connecting sleeve is provided with a spring and a paper cone, and the spring compartment is provided below the paper cone.

[0005] Furthermore, the diameter of the upper opening of the connecting sleeve is smaller than the diameter of the lower opening of the connecting sleeve.

[0006] Furthermore, the bottom of the magnetic bowl is arranged in the basin frame.

[0007] Furthermore, the basin frame is a multi-section bending structure that bends continuously from bottom to top, and the outer edge of the elastic wave outside the connecting sleeve is connected to the basin frame.

[0008] Furthermore, the bottom of the magnetic bowl is arranged at a position where the basin frame assembly hole is upward.

[0009] Furthermore, the voice coil is bonded to the connecting sleeve.

[0010] Furthermore, the paper cone is bonded to the connecting sleeve.

[0011] Furthermore, the elastic wave is bonded to the connecting sleeve.

[0012] The beneficial effects of the utility model are as follows: in order to adapt to the development needs of increasing speaker power requirements and increasingly restricted heights, the utility model utilizes a connecting sleeve to avoid the magnetic bowl to achieve spatial flattening in the height direction of the speaker; specifically, the voice coil, the elastic wave, and the paper cone are all bonded to the connecting sleeve; the connecting sleeve is assembled on the outside of the magnetic bowl, which is equivalent to raising the position of the magnetic bowl upwards, while the overall height of the speaker is lowered; and the vibration space H at the bottom of the elastic wave bonding surface of the basin frame is fully utilized.

[0013] In summary, the utility model has the characteristics of high power and thin thickness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Figures 1 to 4 A speaker with a thin structure is shown, comprising a magnetic bowl 1, a connecting sleeve 2 is sleeved on the upper part of the magnetic bowl 1, and both ends of the connecting sleeve 2 have connected openings, the diameter of the upper opening of the connecting sleeve 2 is smaller than the diameter of the lower opening of the connecting sleeve, that is, the connecting sleeve 2 is a cone with a narrow upper part and a wide lower part, a voice coil 3 is bonded in the opening on the upper side of the connecting sleeve 2, and a spring 4 and a paper cone 5 are bonded to the outside of the connecting sleeve 2, and the spring 4 and the paper cone 5 are installed on the outer wall of the connecting sleeve 2 with an interval up and down.

[0023] The bottom of the magnetic bowl 1 is installed in the basin frame 6, and specifically the bottom of the magnetic bowl 1 is installed at a position where the assembly hole of the basin frame 6 is upward; the basin frame 6 is a multi-section bending structure that is continuously bent from bottom to top, and the outer edge of the outer elastic wave 4 of the connecting sleeve 2 is connected to the basin frame 6.

[0024] Specific assembly

[0025] 1. The original upper opening is combined with the mounting hole of the basin rack, and now the bottom of the magnetic bowl is combined with the mounting hole of the basin rack.

[0026] 2. The voice coil 3, the elastic wave 4 and the paper cone 5 are glued and bonded to the connecting sleeve 2 through a jig to form a vibrating assembly. After the assembly is assembled and cured, the assembly is separated from the jig and glued to the basin frame 6 through magnetic circuit positioning using a special sound gauge to glue the edges of the paper cone 5 and the elastic wave 4. This is similar to the bonding method of the elastic wave and paper cone of a traditional speaker, but it was originally done separately, but now it is assembled at the same time with glue.

[0027] 3. The rest of the assembly is the same as the traditional speakers.

[0028] The utility model Figure 5 Compared to existing speakers shown:

[0029] 1. The assembly position of the magnetic bowl has been optimized.

[0030] 2. The vibration parts of the speaker: voice coil 3, spring 4, and paper cone 5 are assembled through the connecting sleeve 2.

[0031] 3. The space under the bonding surface of the spring wave 4 of the basin frame 6 is fully utilized to assemble the magnetic circuit part.

[0032] 4. A connecting sleeve 2 is used to avoid the magnetic bowl 1, thereby realizing a flat structural design.

[0033] Figure 2 and Figure 4 H in the middle is the vibration space of the utility model. Figure 5 H in the figure is the vibration space of the existing loudspeaker. It can be seen intuitively from the figure that the vibration space H of the utility model has a higher utilization rate.
