Abstract
The utility model relates to a moving -coil microphone specifically includes voice coil loudspeaker voice coil, magnetic ring, support, vibrating diaphragm and T shape iron, and the magnetic ring is fixed in the support below, and the magnetic ring below is equipped with the vibrating diaphragm, and the vibrating diaphragm below is equipped with the sheath, and it has the vocal hole to open on the sheath, T shape iron top is provided with the damping fin, magnetic ring inside wall and lateral wall are opened there is mated notch, the vibrating diaphragm bottom is equipped with flexible connectors, and the vibrating diaphragm passes through flexible connectors and leg joint. This scheme can effectively increase the vibration range of vibrating diaphragm, improves the low frequency effect of receiver.
Description
Technical field
The utility model relates to a kind of moving coil receiver.
Background technology
Receiver is also known as receiver, it is a kind of electro-acoustic element audio electrical signal being converted to voice signal under voiceless sound leakage condition, be widely used in the communication terminal devices such as mobile phone, landline telephone, earphone, realize audio frequency, as the playback of voice and music etc., what use was maximum at present is moving coil receiver.In moving coil receiver, the signal of telecommunication mainly relies on voice coil loudspeaker voice coil forced vibration in the magnetic field of change to the conversion of voice signal, drive diaphragm oscillations to compress the air of ante-chamber simultaneously, after ordering about air vibration, sound is exported from phonation unit, the size also corresponding height determining sound frequency of vibrating diaphragm amplitude range, vibrating diaphragm can Oscillation Amplitude larger, then the sound exported just advantageously, is more suitable for user low frequency being had to corresponding pursuit on low frequency.In addition, in cavity, the effect of vibration of distribution to voice coil loudspeaker voice coil in magnetic field has a great impact.General by reducing film thickness to improve vibrating diaphragm amplitude in prior art, but vibrating diaphragm is too thin can increase receiver installation difficulty, noise increase during receiver work simultaneously.
Summary of the invention
The utility model provides a kind of moving coil receiver, and specifically comprise voice coil loudspeaker voice coil, magnet ring, support, vibrating diaphragm and T-shaped iron, magnet ring is fixed on below support, is provided with vibrating diaphragm below magnet ring, is provided with sheath below vibrating diaphragm, and sheath has vocal hole; Damping fin is provided with above described T-shaped iron; Described magnet ring madial wall and lateral wall have paired notch; Be provided with Flexible Connector bottom described vibrating diaphragm, vibrating diaphragm is connected with support by Flexible Connector.
Further, Flexible Connector is spring or metal clips.
Further, magnet ring fluting shape is arc or rectangle.
Further, magnet ring fluting quantity is 2 ~ 4 right.
Vibrating diaphragm is connected with support by Flexible Connector by this programme, effectively can increase the Oscillation Amplitude of vibrating diaphragm, improves the low-frequency effect of receiver, and without noise, and receiver is installed simple; In addition, by slotting on magnet ring, the Distribution of Magnetic Field uniformity can be improved, also can improve the sounding effect of receiver.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is magnet ring cross sectional representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model; those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
A kind of moving coil receiver as illustrated in fig. 1 and 2, specifically comprises voice coil loudspeaker voice coil 9, magnet ring 2, support 1, vibrating diaphragm 5 and T-shaped iron 8, and magnet ring 2 is fixed on below support 1, is provided with vibrating diaphragm 5 below magnet ring 2, is provided with sheath 6 below vibrating diaphragm 5, and sheath 6 has vocal hole; Damping fin 7 is provided with above described T-shaped iron 8; Described magnet ring 2 madial wall and lateral wall have paired notch; Be provided with Flexible Connector 4 bottom described vibrating diaphragm 5, vibrating diaphragm 5 is connected with support 1 by Flexible Connector 4.Flexible Connector 4 is spring or metal clips.Magnet ring 2 shape of slotting is arc or rectangle, and fluting quantity is 2 ~ 4 right.
Vibrating diaphragm is connected with support by Flexible Connector by this programme, effectively can increase the Oscillation Amplitude of vibrating diaphragm, improves the low-frequency effect of receiver, and without noise, and receiver is installed simple; In addition, by slotting on magnet ring, the Distribution of Magnetic Field uniformity can be improved, also can improve the sounding effect of receiver.
