Description

Technical Field

[0001] The utility model relates to the field of audio, in particular to a novel diaphragm with a suspension edge for a moving iron speaker. Background Art

[0002] A balanced armature speaker is an audio device that uses an electromagnetic coil to generate an alternating magnetic field, causing a vibrating plate to produce sound. Characterized by their compact size and high sensitivity, balanced armature speakers have expanded from early applications in telephones, ringtones, and hearing aids to a wider range of audio devices. Today, balanced armature speakers are a crucial component of many headphones and sound systems.

[0003] Currently, common dynamic armature speakers on the market suffer from insufficient diaphragm amplitude, resulting in relatively weak low-frequency performance and a relatively narrow frequency response range. Therefore, this utility model provides a new solution to this problem through structural improvements and enhancements. Summary of the Invention

DETAILED DESCRIPTION

[0013] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0014] In this embodiment, refer to Figure 1-Figure 3 The invention specifically implements a novel diaphragm with a suspension for a dynamic iron speaker. The diaphragm comprises a balance plate 1 and a diaphragm. An electromagnetic coil 7 is disposed in the center of the balance plate 1. Balance plates 1 are disposed at both ends of the diaphragm. The diaphragm comprises a center plate 2 and an elastic diaphragm 3. The center plate 2 is made of iron or a magnetically permeable material. When current passes through the electromagnetic coil 7, the magnetic field generated by the center plate 2 causes the center plate 2 to respond quickly. Efficient energy conversion helps improve sound output power and response speed.

[0015] Furthermore, the chip 8 is arranged at the bottom of the diaphragm and fits with the balance plate 1 arranged at the bottom. The chip 8 is fixed to the bottom of the diaphragm by glue. The chip 8 is electrically connected to the electromagnetic coil 7 at the upper and lower ends. The chip 8 is used to control the current of the electromagnetic coil 7, which changes the magnetic field inside the diaphragm. Therefore, the elastic diaphragm 3 moves back and forth at the center position to push the air, thereby allowing the speaker to make sound.

[0016] Furthermore, the elastic diaphragm 3 is preferably made of a material with good elasticity such as plastic. The elastic diaphragm 3 has the characteristic of rapid recovery. The lower end of the center piece 2 is fixed to the elastic diaphragm 3 by glue, so that the elastic diaphragm 3 can drive the center piece 2 to recover quickly, ensuring the stability of audio signal transmission and reducing noise caused by shaking or misalignment of the center piece 2, thereby improving the purity and clarity of the sound quality.

[0017] Furthermore, the two balance pieces 1 are respectively arranged at the upper end of the first support ring 5 and the lower end of the second support ring 6. The thickness of the first support ring 5 is greater than the thickness of the second support ring 6, so that the distance between the center piece 2 and the two electromagnetic coils 7 remains consistent, so as to keep the center piece 2 in the center of the magnetic field and vibrate back and forth. Therefore, the center piece 2 is in a uniform magnetic field environment, which makes the vibration of the center piece 2 more regular, reduces the nonlinear distortion caused by the uneven magnetic field, and improves the clarity and purity of the sound quality.

[0018] Furthermore, the edges of the elastic diaphragm 3 are secured by a first support ring 5 and a second support ring 6, thereby not affecting the vibration of the elastic diaphragm 3 and the center piece 2. A gap exists between the center piece 2 and the first support ring 5, forming a cantilever portion 4 on the elastic diaphragm 3 corresponding to the gap. Furthermore, the design of the cantilever portion 4 increases the amplitude of the diaphragm, resolving the problem of insufficient diaphragm amplitude, thereby enhancing low-frequency expressiveness. The large vibration amplitude enables more accurate reproduction of sound details, making music sound more natural and vivid, further improving sound quality and the listening experience.

[0019] The utility model installs the center piece 2 on the elastic diaphragm 3. When the center piece 2 vibrates, the elastic diaphragm 3 can help the center piece 2 to quickly reset, avoiding noise, thereby improving the purity and clarity of the sound quality. Furthermore, the design of the suspension part 4 completely solves the problem of insufficient diaphragm amplitude, improves the expressiveness of low frequencies, and enables the dynamic iron speaker to have a sound field from low frequencies to high frequencies in one speaker, taking into account the balance of three frequencies, thereby improving the sound quality and listening experience of the entire frequency band.

Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
