Abstract
A method for detecting air-leakage of loudspeaker includes clamping edge of support on loudspeaker separately by air inlet box and air outlet box, injecting air into air inlet box to generate pressure in inlet box, observing whether air bubble is occurred in water contained in water container connected with air outlet box or not, judging that loudspeaker is air-leaked one if it is or otherwise judging that loudspeaker is not leaked one. The device used for realizing said method is also disclosed.
Description
Technical field
The invention belongs to a kind of method of inspection of loud speaker, particularly a kind of air leakage detecting method of loud speaker.
Background technology
Qualified loud speaker is bondd securely by each parts, as is bonded with the slit, will make loud speaker produce gas leak phenomenon, and at present, whether the method whether the check loud speaker leaks gas is the method for inspection of listening pure tone with standard, recognize loud speaker and leak gas.According to description at GB9396-1996 " loud speaker main performance method of testing " the 17th, the loudspeaker unit detection is in rated frequency range, the electrical power of the loud speaker sinusoidal signal of feeding is 1/2nd nominal noise powers, generally at 0.3 meter detection, at this apart from planted agent's areflexia thing, loudspeaker unit does not add acoustic load in addition, to check the assembly quality of loud speaker.Detection person can judge whether loudspeaker unit has gas leakage according to experience, still, if the loud speaker volume is little, also is very small if loud speaker has gas leakage, and people's ear is difficult to hear that therefore this method accuracy of detection is not high, and efficient is very low.
Summary of the invention
The object of the invention is to solve the problem that existing technology exists, and a kind of air leakage detecting method and verifying attachment thereof of loud speaker is provided, and this method check accurately, checkability is high, and the used verifying attachment of this method is simple in structure, operation easily.
The method that the present invention adopts has comprised the following step:
(a) clamp the bracket edge (13) of loud speaker (8) respectively with air inlet casing (9) and the casing of giving vent to anger (7);
(b) in air inlet casing (9), inject air and air inlet casing (9) in generation air pressure;
Whether (C) observe and have bubble to occur in the water (12) of the water receptacle (2) that is communicated with the casing of giving vent to anger (7), as occur bubble, then be judged to be loud speaker gas leakage, as do not have bubble to occur, it is air tight then to be judged to be loud speaker.
Can improve the accuracy of loud speaker gas leakage check by the method, can reduce personnel labor, improve the operating efficiency of check.

Embodiment
In Fig. 2, before the verifying attachment check, pressure handspike (6) spurs the casing (7) of giving vent to anger and is in open mode;
In Fig. 3, loud speaker to be tested (8) is put on the air inlet casing (9), loud speaker (8) just face the A direction oppositely, air inlet casing (9) is held loud speaker (8) bracket edge;
In Fig. 4, pressure handspike (6) casing (7) that promotes to give vent to anger moves to the A direction, use the bracket edge (13) of gas tank body (7) and air inlet casing (9) clamping loud speaker (8), loud speaker (8) is smooth seamless with the contact-making surface of air inlet casing (9), and loud speaker (8) is smooth seamless with the contact-making surface of the casing (7) of giving vent to anger.Inject air with air pump (11) by the air inlet (10) of air inlet pipe (5) to air inlet casing (9), and at air inlet casing (9) generation air pressure, if loud speaker (8) has gas leakage, then have air and in air inlet casing (9), pass loud speaker (8), enter in the casing of giving vent to anger (7), air will be discharged to the transparent water container (2) that water (12) is housed through escape pipe (4) from the gas outlet (3) of the casing of giving vent to anger (7), water (12) in the water receptacle (2) just has bubble and produces, and then decidable is loud speaker gas leakage; If loud speaker (8) is air tight, just do not have air and do not enter into the casing of giving vent to anger (7), thereby do not have in the water (12) that air is discharged to water receptacle (2) from air inlet casing (9), then decidable is that loud speaker is air tight.This method can improve the accuracy of check, has reduced personnel labor, improves the operating efficiency of check.
In Fig. 6, loud speaker (8) just faced the A direction, put on the air inlet casing (9), air inlet casing (9) is held loud speaker (8) bracket edge, pressure handspike (6) casing (7) that promotes to give vent to anger moves to the A direction, use the bracket edge (13) of gas tank body (7) and air inlet casing (9) clamping loud speaker (8), loud speaker (8) is smooth seamless with the contact-making surface of air inlet casing (9), loud speaker (8) is smooth seamless with the contact-making surface of the casing (7) of giving vent to anger, inject air with air pump (11) by the air inlet (10) of air inlet pipe (5) to air inlet casing (9), and at air inlet casing (9) generation air pressure, if loud speaker (8) has gas leakage, then have air and in air inlet casing (9), pass loud speaker (8), enter in the casing of giving vent to anger (7), air will be discharged to the transparent water container (2) that water (12) is housed through escape pipe (4) from the gas outlet (3) of the casing of giving vent to anger (7), and the water (12) in the water receptacle (2) just has bubble and produces, and then decidable is loud speaker gas leakage; If loud speaker (8) is air tight, just do not have air and do not enter into the casing of giving vent to anger (7), thereby do not have in the water (12) that air is discharged to water receptacle (2) from air inlet casing (9), then decidable is that loud speaker is air tight.This method can improve the accuracy of check, has reduced personnel labor, improves the operating efficiency of check.
