Embodiment 1

The present embodiment provides a kind of receiver, as shown in figure 3, including housing 2, Yin Mo mechanisms 3 and vibrating mechanism 4.

As shown in figure 3, housing 2 includes the first housing 21 formed with first chamber 23 and the formed with second chamber 24 Two housings 22, the first housing 21 and the second housing 22 can be fastened and connected, wherein sound regulating hole 211 is provided with the first housing 21, the Sound outlet hole 221 is provided with two housings 22.Inner cavity is separated into first chamber 23 and second chamber 24, sound film machine by Yin Mo mechanisms 3 Structure 3 is arranged between the first housing 21 and the second housing 22 or Yin Mo mechanisms 3 are fastened in the opening of the first housing 21.Sound film Mechanism 3 includes oscillating plate 1 and covers 1 surface of oscillating plate and the sound film 31 in second chamber 24.

The oscillating plate 1 of the present embodiment, as depicted in figs. 1 and 2, including frame part 11 and plate 12, plate 12 are arranged at frame In component 11, its one end is fixed on frame part 11, and the other end can free vibration.Frame part 11 and the upper-lower casing of receiver are kept It is fixedly connected, the surface of sound film covering plate 12 is simultaneously fixed with frame part 11, and the middle part of sound film is fixedly connected with plate 12.

As shown in figure 3, the vibrating mechanism 4 of the present embodiment includes electromagnet unit 41 and permanent magnet 42, electromagnet unit 41 It is arranged in first chamber 23 and is fixedly connected with plate 12.Electromagnet unit 41 includes U-shaped armature 411 and is set in part Coil 412 on U-shaped armature 411.Specifically, U-shaped armature 411 includes two the first arm units 4111 and second being arranged in parallel Arm unit 4112, wherein being arranged with coil 412 on the second arm unit 4112, the first arm unit 4111 is fixed with plate 12 to be connected Connect, and the first arm unit 4111 and plate 12 are fixedly connected with fixation end of the portion away from plate 12.In the present embodiment One arm unit 4111 is longer than the second arm unit 4112, and two permanent magnets 42 are separately positioned in first chamber 23 and second chamber 24 The both sides at 4112 position of the second arm unit are stretched out positioned at the first arm unit 4111.The magnetic pole of two permanent magnets 42 is corresponding to be set Put, and the opposite polarity of two magnetic poles is set.

The step 121 for protruding its surface is further included in the present embodiment on the plate 12 of oscillating plate 1, step 121 is along away from electricity Protrude the surface of plate 12 in magnet direction.Step 121 in the present embodiment be protrusion plate 12 apparent height be not less than The step of 0.1mm, the step 121 of plate 12 are arranged on the region beyond region opposite with permanent magnet 42 on plate 12.Such as Fig. 3 It is shown, wherein the first arm unit 4111 is set with the portion that is fixedly connected of plate 12 away from plate 12 and the fixation end of frame part 11 Put, since the first arm unit 4111 is away from its one end (i.e. close plate 12 and frame part 11 with the fixed part of plate 12 One end of fixed end) Oscillation Amplitude is larger, therefore the step 121 in the present embodiment is close to the fixation of plate 12 and frame part 11 End set.The forced vibration under the driving of magnetic force of the free end of plate 12, and plate 12 fixes end to free end from it Amplitude constantly become larger.By 121 part of step being arranged on plate 12 can increase between plate 12 and armature 411 away from From to avoid collision；It can in addition contain increase the vibration energy storage of plate 12, increase the amplitude of plate 12.

The through hole 122 for allowing magnetic circuit to pass through is additionally provided with plate 12 in the present embodiment, through hole 122 is arranged at The region of step 121 is not provided with plate 12, is set by fixing end of the step 121 in this present embodiment close to plate 12, because Through hole 122 in this present embodiment is arranged on plate 12 away from its fixation end with frame part 11, and through hole 122 with forever Magnet 42 is accordingly set, can make permanent magnet 42 magnetic field it is without hindrance by plate 12 to reduce magnetic field by plate 12 when Magnetic losses.

The course of work of receiver in present embodiment is：Initial state lower coil 412 is not powered on, and armature 411 is to lead Magnetic material is made, and the fixed magnetic field of permanent magnet 42 cancels out each other the active force of the first arm unit 4111 so that the of armature 411 One arm unit, 4111 balance state.After coil 412 connects AC power, electromagnet produces alternating magnetic field so that first The end of arm unit 4111 has the magnetism of change, in end alternating magnetic field and the fixed magnetic field phase interaction of the first arm unit 4111 Under, permanent magnet 42 constantly changes the force direction of 4111 end of the first arm unit so that the first arm unit 4111 is herein Produced under active force of reciprocating vibration.First arm unit 4111 is fixedly connected with portion by conduct vibrations to plate with plate 12 by it On 12 so that plate 12 does forced vibration.The vibration of plate 12 is conducted to sound film 31 again so that sound film 31 agitates air and then hair Sound.

As interchangeable embodiment, through hole 122 can not also be set, plate 12 uses high permeability material on plate 12 Be made, can reduce through the magnetic field of plate 12 by plate 12 when loss.

As interchangeable embodiment, step 121 can not also be close to the fixation end of plate 12, as long as corresponding The region for needing to increase distance between armature and oscillating plate is provided with step 121.

Multiple steps 121 can also be set as interchangeable embodiment, on plate 12, as long as in plate 12 and armature 411 regions that may be collided can be provided with step.

As interchangeable embodiment, 121 part of step of plate 12 can also be arranged on plate 12 and permanent magnet 42 opposite regions, as long as the height of step 121 meets plate 12 will not be caused to collide permanent magnet 42 in vibration processes i.e. Can.

As interchangeable embodiment, the first arm unit 4111 can not also be longer than the second arm unit 4112, as long as two A permanent magnet 42 can be arranged on 4111 both sides of the first arm unit, in the alternation magnetic of the fixed magnetic field and coil 412 of permanent magnet 42 Under the collective effect of field so that the first arm unit 4111 produces vibration.

As interchangeable embodiment, the first arm unit 4111 can not also be away from plate with the portion that is fixedly connected of plate 12 The fixation end of part 12, as long as the active force foot under the alternating magnetic field collective effect of the fixed magnetic field of permanent magnet 42 and coil 412 It is enough big, enable to the first arm unit 4111 to produce vibration, and forced vibration can be done i.e. by fixed connection point plate 12 Can.

Oscillating plate provided by the utility model has the step part of a protrusion plate surface so that plate and armature it Between distance become larger so that plate in vibration processes will not with armature produce collision；Adopt the structure oscillating plate by Device is talked about, keeps for the mounting distance between armature and oscillating plate not limited because of the reduction of size after receiver is thinning System, causes receiver audio distortions so as to avoid the problem that collision occur in armature and plate.

Obviously, the above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or Among the protection domain that variation is created still in the utility model.
