Microphone testing device

Abstract

This invention discloses a horn testing device, comprising: a baffle plate; a horn fixture installed within the baffle plate; and a clamp fixed to the front surface of the baffle plate and disposed on one side of the horn fixture. The clamp includes a fixing part, a positioning member, a positioning rod, two movable parts, and two nuts. The positioning member is disposed on one side of the front end of the fixing part. One end of the positioning rod is disposed within the positioning member. The movable parts include a main body, a through hole, and two extensions. The main body is disposed on the front and rear surfaces of the positioning member. One end of the positioning rod passes through the two through holes. The two nuts are fixed to the front and rear surfaces of the two main bodies. The upper and lower ends of the main body extend rearward to form the two extensions, which are disposed on the upper and lower surfaces of the positioning member. Therefore, this horn testing device can improve testing flexibility, testing applicability, and testing convenience.

Claims

1. A horn testing device, comprising: A baffle plate has a test hole penetrating its front and rear surfaces, with the inner side of the test hole extending inward to form a protrusion; a horn fixture is installed in the test hole, the horn fixture having a front part and a rear part, the front part extending rearward to form the rear part, the front part being fixed in the test hole, and the rear part engaging with the protrusion; and a clamp fixed to the front surface of the baffle plate and disposed on one side of the horn fixture, the clamp having a fixing part, a positioning element, a positioning rod, two movable parts, two nuts, and a contact part, the fixing part being disposed on the front surface of the baffle plate, and the positioning element being disposed on the fixing part. On one front side, one end of the positioning rod is disposed inside the positioning member, and the other end of the positioning rod extends rearward to form the contact portion. The two movable members are respectively disposed on the front and rear surfaces of the positioning member. The movable member has a body part, a through hole, and two extension parts. The body part is disposed on the front and rear surfaces of the positioning member. The movable member has the through hole that penetrates the front and rear surfaces of the body part. One end of the positioning rod passes through the two through holes. The two nuts are fixed to the front and rear surfaces of the two body parts. The upper and lower ends of the body part extend rearward to form the two extension parts. The two extension parts are disposed on the upper and lower surfaces of the positioning member.

2. The horn testing apparatus as claimed in claim 1, wherein a pressing part is provided on the other side of the front end of the fixing part, and the positioning member is closer to the horn fixture than the pressing part.

3. The horn testing apparatus as claimed in claim 1, wherein the outer diameter of the front portion is larger than the outer diameter of the rear portion.
