Electronic horn device and method

An electronic horn device, comprising:

• a set of a plurality of horn modules coupled to a mount that is configured to be disposed onboard a vehicle, each of the plurality of horn modules comprising:
• a plurality of compression drivers;
• and
• a horn body including a bell segment and a plurality of branch segments fluidly connected to the bell segment, each of the plurality of compression drivers respectively mounted to respective ends of the plurality of branch segments of the horn body;
• one or more amplifiers operably connected to the plurality of compression drivers of the plurality of horn modules of the set;
• a controller comprising one or more processors and operably connected to the one or more amplifiers, the controller configured to control the one or more amplifiers to power the plurality of compression drivers of one or more of the plurality of horn modules to generate (i) a horn sound based on receipt of a first control signal, (ii) a bell sound based on receipt of a second control signal, and (iii) a combined horn and bell sound based on receipt of a third control signal or receipt of both the first and second control signals within a designated period of time, wherein the horn sound, the bell sound, and the combined horn and bell sound are emitted from the bell segment of the respective horn body of each of the plurality of horn modules;
• and
• a DC-to-DC converter to source power to the electronic horn device.

A locomotive horn device, comprising:

• a first horn module configured to be mounted onboard a locomotive, the first horn module comprising:
• a plurality of compression drivers;
• and
• a horn body including a bell segment and a plurality of branch segments fluidly connected to the bell segment, the each of the plurality of compression drivers respectively mounted to respective ends of the plurality of branch segments of the horn body;
• one or more amplifiers operably connected to the plurality of compression drivers of the first horn module;
• a controller comprising one or more processors and operably connected to the first horn module via the one or more amplifiers, the controller configured to control the plurality of compression drivers to generate a horn sound that is emitted from the bell segment of the horn body in response to receipt of a first control signal, and to control the plurality of compression drivers to generate a bell sound that is emitted from the bell segment in response to a receipt of a second control signal;
• and
• a DC-to-DC converter to source power to the locomotive horn device.
