できなかった。(Prior Art and Problems to be Solved by the Invention) The frame of a speaker is a base body to which the parts of the vibrating part, the rigid road, and other parts are attached. Generally, it is made by pressing a steel plate, resin molding, or casting or guicasting of aluminum, zinc, etc. Especially in the case of a woofer, a closed frame is used to prevent the diaphragm from being stirred up by back pressure and to control the low-frequency Q using a cavity. However, when a closed type frame is used, when a non-ventilated diaphragm is bonded to the frame with an adhesive, the adhesive paper fills the frame cavity, severely hindering the curing of the adhesive. Therefore, there are problems such as it takes time for the adhesive to harden and the adhesion is insufficient, so it is not possible to use a highly airtight diaphragm such as a film in a speaker using a closed frame. There wasn't.

A first method of manufacturing a closed frame speaker, which comprises bonding an empty diaphragm with an adhesive, and subsequently removing volatile components of the solvent of the adhesive from the ventilation hole, and then air-sealing the ventilation hole. The second summary is a method for manufacturing a closed frame speaker using an eyelet hole for terminal attachment or a hole for a voice coil lead wire as a ventilation hole.

A non-ventilated diaphragm 5 with a non-ventilated diaphragm 5 fixed to the top of the diaphragm 5 is fixed to the frame 2 via a damper 6 using an adhesive, and the diaphragm 5 is fixed to the periphery of the frame 2 using an adhesive opening 7 of the diaphragm 5.
Then, after the adhesive is solidified and the volatile components of the adhesive's solvent are released from the frame cavity 8, the vent hole 3 is sealed with a seal 9. Thus, frame cavity 8
The volatile content of the solvent inward is released to the outside and the adhesive is completely solidified.
