Tongyong provided custom metal housing fabrication for an HDMI audio extractor. This case focuses on the housing and its fit with the electronic components. To protect customer information, we do not disclose the customer's name or specific order details.
Housing Structure and Component Fit
Our work focused on the metal housing, which forms the product's exterior and must accommodate the circuit board, front and rear connectors, and mounting features. Connector positions, PCB mounting and access for assembly and disassembly all affect the requirements for the metal parts.
The market product below provides a reference for the size and interface layout of this type of device. Its dimensions and configuration illustrate a typical product format; they are not the specifications of the product delivered in this case.
| Reference model | Dimensions or visible features |
|---|---|
| Overall dimensions | 58 × 53 × 21.9 mm |
| Input side | HDMI input, mode selector, indicator and Micro USB power port |
| Output side | HDMI output, TOSLINK optical output and 3.5 mm audio jack |
| Housing appearance | Black metal body with screw-fastened front and rear interface panels |
PCB and Connector Alignment
The interface panels and circuit board need to be considered together. The PCB mounting position and support height affect how the board-mounted connectors align with the panel cutouts. Panel thickness and the length of connector projection also affect whether a plug can be fully inserted. These relationships need to be defined when matching the housing to the electronic components.
Around the HDMI ports, the fit also depends on the dimensions of the plug's molded body, the spacing between adjacent connectors and the room for cables to exit. The positions of audio and power ports, switches and indicators depend on the customer's PCB and product version. The way the body, cover and panels join together must also allow the components to be installed and removed.
Together, these details define the fabrication requirements for a compact audio-video equipment housing.
Custom Housings and Panels for Audio and Video Equipment
Beyond HDMI audio extractors, we provide custom sheet metal housings for converters, switchers, encoders, decoders and desktop audio equipment, as well as small amplifier chassis.
You can order a complete set of metal housing parts or individual front and rear interface panels, covers or other panels. If you already have an extruded aluminum body, we can make front and rear panels to suit its mounting features.
To discuss a housing or panel project, contact us with your existing drawings, PCB layout or connector information. If you do not yet have complete housing drawings, tell us what the product does and which parts you need fabricated.
FAQ
Can the Housing Accommodate Both TOSLINK Optical and 3.5 mm Audio Outputs?
Yes, when both connectors are included in your PCB design. The panel cutouts need to match the connector drawings, their positions relative to the board and the space required to insert the plugs. Power ports, switches and indicators can be arranged to suit your product configuration.
What Should Be Checked When Fitting the PCB into the Housing?
Check the board dimensions, mounting-hole positions, support height and component clearances. For board-mounted connectors, review the panel cutouts and panel thickness together with connector projection and plug access. These details help define how the board and housing fit together.
Can You Make Custom Front and Rear Panels for an Existing Housing?
Yes. We can make front and rear interface panels separately for an existing housing body. Send the housing dimensions, panel attachment details and connector layout. For an extruded aluminum body, include the end profile and screw locations so the panel fit can be reviewed.
What Is an HDMI Audio Extractor?
An HDMI audio extractor separates audio from an HDMI signal and provides separate audio outputs while passing video to a display. Outputs vary by model and may include TOSLINK optical or a 3.5 mm audio jack. Tongyong’s work in this case concerns the metal housing and interface panels.
