It is defined in an attached drawing, then in subsequent attached drawing does not need that it is further discussed.
Fig. 1 is the sounding device that an embodiment of the present invention provides.As shown in Figure 1, the sounding device, comprising: vibration
System, magnetic circuit system and the shell 3 for accommodating fixed vibrational system and magnetic circuit system；Vibrational system includes voice coil 10；Magnetic circuit system
System includes the first magnetic conductive board 20 on 101 routing path of lead of voice coil 10；The setting of lead 101 of voice coil 10 is led first
On magnetic sheet 20；First magnetic conductive board 20 is provided with the evacuation that evacuation lead 101 vibrates on the first end of 101 exit of lead
Slot 201.
In technical solution provided by the embodiment of the utility model, since lead is close to the partial vibration amplitude of lead exit
The collision dynamics of maximum, this part and the first magnetic conductive board is maximum.Pass through the first end in the first magnetic conductive board close to lead exit
Escape groove is arranged in portion effectively to avoid part and first magnetic conductive board of the lead close to lead exit when sounding device works
Collision, thus effectively reduce lead collide caused by noise, improve acoustical behavior.In addition, can be kept away by the design of escape groove
The problem of exempting from lead broken string, improves the service life of sounding device.
In a kind of specific implementation structure, vibrational system includes vibrating diaphragm (not shown) and the voice coil for being incorporated into vibrating diaphragm side
10.Voice coil 10 includes voice coil ontology and lead 101.Lead 101 may include electrode line and negative line.Magnetic circuit system include magnetic yoke,
The centring magnet and side magnet being incorporated in magnetic yoke are incorporated in the center magnetic conductive board of centring magnet upper surface, are incorporated in side magnet
The side magnetic conductive board of upper surface.Magnetic gap is formed between centring magnet and side magnet, voice coil 10 is suspended in magnetic gap.Magnetic circuit system
It can be three magnetic circuit systems or five magnetic circuit systems.
When for three magnetic circuit systems, the quantity of side magnet is two, and the opposite sides of centrally disposed magnet, is incorporated in
The magnetic conductive board in two on magnet of opposite sides is laid wherein as above-mentioned first magnetic conductive board, the electrode line of lead 101
On one side magnetic conductive board, the negative line of lead 101 is laid on another side magnetic conductive board.
When for five magnetic circuit systems, the quantity of side magnet is four, and four side magnet are opposite two-by-two, and surrounds centring magnet
Setting, every piece of magnetic conductive board when the upper surface of magnet is combined with, any two opposite side magnetic conductive boards are led as above-mentioned first
Magnetic sheet, the electrode line of lead 101 are laid on one of side magnetic conductive board, and the negative line of lead 101 is laid in another side and leads
On magnetic sheet.
In general, lead 101 is laid in the upper surface of the first magnetic conductive board 20, when lead 101 vibrates easily with the first magnetic conductive board 20
Upper surface collide, therefore, the upper surface of the first end of first magnetic conductive board 20 is arranged in escape groove 201, that is, keeps away
Slot 201 is allowed to be to be recessed downwards to be formed by the upper surface of the first end of the first magnetic conductive board 20.In order to meet Current electronic product
Miniaturization Design demand, the volume of sounding device also design smaller and smaller, and the design space for leaving escape groove for is limited.This
In the case of, in order to ensure the evacuation function of escape groove can be realized normally, escape groove 201 can be run through to the inside of first end
Face, wherein the side of the voice coil ontology of the close voice coil 10 of first end is medial surface.In this way, it is possible to increase the slot of escape groove 201
Open area is avoided because notch area is too small and installation error, when lead being caused the to vibrate and cell wall upper surface of escape groove hair
Raw collision.
In a specific structure, the outside of the first magnetic conductive board 201 is moulded in 3 inner wall of shell, can not only reduce volume, moreover it is possible to
Fixed function is played to magnetic circuit system.In order to increase notch area, escape groove 201 can be arranged along 3 inner wall of shell.
Above-mentioned escape groove 201 can be surface groove or to face slot directly, in the present embodiment not to the shape of escape groove 201
Make specific restriction, is vibrated as long as evacuation lead 101 can be played.
In a kind of achievable structure, as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, escape groove 201 is surface groove, that is, is avoided
The slot bottom of slot is inclined-plane.Since lead 101 is bigger closer to the partial vibration amplitude of exit, the minimum point of surface groove
Highest point compared with surface groove should be arranged close to 101 exit of lead.Groove depth at the minimum point of surface groove is greater than surface groove most
Groove depth at high point.Shape change to the first magnetic conductive board can be reduced using surface groove, reduce the setting of escape groove 201 to first
The influence of the magnetic line of force debugging functions of magnetic conductive board.
In another achievable structure, as shown in Fig. 6, Fig. 7, Fig. 8, Fig. 9 and Figure 10, the escape groove 201 is straight
Face slot, the i.e. slot bottom of escape groove are to face (i.e. plane) directly.
The part opposite with escape groove 201 of lead 101 can be hung in escape groove 201 or by colloid and escape groove
201 slot bottom realizes connection.The constraint to lead 101 can be increased by colloid, the Oscillation Amplitude of lead can be reduced in this way.Specifically
Ground, colloid can be flexible glue, in this way lead when the vibrations are up and down, colloid can stretch, and be increased by the elastic force of colloid to lead
Constraint, to reduce the Oscillation Amplitude of lead.As shown in Figure 1, lead 101 reaches the first magnetic conductive board after the extraction of voice coil ontology
There is also one section of suspending part 1011, the U-shaped structures of the suspending part before 20.
