Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a two-in-one stroke sound-adding membrane. Background Art

[0002] The loudspeaker, commonly known as the "horn", is a very commonly used electroacoustic transducer device. It can be found in all sound-generating electronic and electrical equipment. In speaker audio, the maximum travel of the speaker voice coil is called the "stroke", and the sound membrane is the playback diaphragm of the speaker. In the dome speaker, for the convenience of assembly, the dome membrane and the voice coil are often bonded together to form a component, which we call the sound membrane.

[0003] At present, the single stroke requires the speakers to be thinner and smaller, which cannot keep up with the requirements of the electronics industry. The overall volume of the existing speaker structure is too large. At the same time, when the volume is high, it is easy to have a realistic and uncontrolled over-power situation. It is necessary to control and reduce the sound output, resulting in the sacrifice of volume. To solve the above problems, a two-in-one stroke plus sound membrane is provided here. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a two-in-one stroke sound-added membrane, aiming to improve the problem of the prior art that the overall structure is large and the high-frequency distortion cannot be avoided.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: comprising a stroke sound membrane, the stroke sound membrane is composed of a stroke and a sound membrane, the top of the stroke sound membrane is covered with a cover plate, the center of the bottom end of the cover plate is bonded with a shock-absorbing foam, and a gap is provided between the shock-absorbing foam and the stroke sound membrane, and frames are installed on both sides of the cover plate and the magnet;

[0006] As a further description of the above technical solution:

[0007] A magnet is arranged at the bottom of the cover plate, and a gap is arranged between the top of the magnet and the stroke sound membrane.

[0008] As a further description of the above technical solution:

[0009] The stroke structure adopts a copper coil structure, and the stroke is fixedly connected to the sound membrane to form an integrated thin film structure.

[0010] As a further description of the above technical solution:

[0011] The stroke copper coil structure is designed to be wound from outside to inside, and two ends of the stroke copper coil structure are respectively connected to positive and negative electrodes.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, the stroke and the sound membrane are combined into a thin sheet structure, which greatly reduces the volume of the product, makes the product smaller and thinner, and better meets the requirements of highly compact and integrated existing electronic products. At the same time, it is more conducive to product production and improves production efficiency. The application can use shock-absorbing foam to minimize distortion while ensuring a high volume of the speaker. Therefore, foam is used on the impact surface of the sound membrane to reduce the noise caused by the large-scale vibration impact of the stroke membrane, which leads to distortion and uncontrolled overpower.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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] Reference Figure 1-5 The utility model provides an embodiment: comprising a stroke sound membrane 1, the stroke sound membrane 1 is composed of a stroke 101 and a sound membrane 102, the top of the stroke sound membrane 1 is covered with a cover plate 2, the bottom center of the cover plate 2 is bonded with a shock-absorbing foam 3, and a gap is provided between the shock-absorbing foam 3 and the stroke sound membrane 1, and frames 5 are installed on both sides of the cover plate 2 and the magnet 4;

[0023] A magnet 4 is disposed at the bottom of the cover plate 2 , and a gap is provided between the top of the magnet 4 and the stroke sound membrane 1 .

[0024] The stroke 101 structure adopts a copper coil structure, and the stroke 101 and the sound membrane 102 are fixedly connected to form an integrated thin sheet structure.

[0025] The stroke 101 copper coil structure is designed to be wound from the outside to the inside, and the two ends of the stroke 101 copper coil structure are respectively connected to the positive and negative poles.

[0026] Specifically, the stroke sound film 1 structure used in the present application is composed of a thin sheet of sound film 102 and a copper coil stroke 101 structure connected to the top. Compared with the stroke thickness in the prior art, the overall volume of the speaker is greatly reduced, thereby improving production efficiency. The stroke sound film 1 is separated from the cover plate 2 and the magnet 4 by a frame 5. The copper coil stroke 101 used in the present application can be made of different structures such as square coils and circular coils. Both ends of the copper coil of the stroke 101 can be set as positive and negative pole structures, so that the stroke 101 is connected to an external device. The shock-absorbing foam 3 is fixed and bonded through the cover plate 2. When the stroke sound film 1 is overloaded and generates distortion and noise, the impact force of the sound film 102 can be absorbed by the material of the shock-absorbing foam 3 silicone foam to reduce the noise caused by the large-scale vibration of the stroke 101. The magnet 4 is used to generate an electric field reaction with the stroke 101. When the electric field reaction is generated, the stroke sound film 1 rushes upward to generate vibration, and the vibration is squeezed with the air to generate sound.

[0027] Working principle: During production, the sound membrane 102 and the stroke 101 are fixed together to form a thin sheet structure. The copper coil structure of the stroke 101 is electrically connected to an external device, the diaphragm 3 is protected and bonded through the cover 2, and the stroke sound membrane 1 is placed between the magnet 4 and the cover 2. The electric field reaction between the magnet 4 and the stroke 101 drives the diaphragm 3 to vibrate and produce sound.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
