The global electric motor horn market size was valued at USD 2.56 billion in 2024 and is estimated to reach USD 4.66 billion by 2033, growing at a CAGR of 6.89% during the forecast period (2025–2033). Innovations in electric motor technology, such as improved efficiency and reduced size, enable the development of more compact and powerful horns. These technological improvements cater to the growing need for high-performance horns in various applications, including vehicles and industrial machinery.
An electric motor horn is a type of sound-emitting device powered by an electric motor commonly used in vehicles, machinery, and other applications that require an audible alert or warning. Unlike traditional air horns, which rely on compressed air, electric motor horns generate sound through an electric motor driving a diaphragm or bell mechanism. These horns are more energy-efficient, compact, and reliable, making them especially suitable for modern EVs that require low-power, space-saving components. Electric motor horns offer benefits like quieter operation, reduced environmental impact, and the ability to produce a consistent and clear tone, ensuring safety and effective communication in traffic or industrial environments.
The growing demand for electric vehicles (EVs) is a key driver of the global electric motor horn market. As global automakers transition toward cleaner, more sustainable alternatives, EV production has surged. In 2024, global EV sales reached over 15 million units, with the International Energy Agency (IEA) predicting further growth in the coming years, particularly in regions like Europe and China.
One of the key restraints in the electric motor horn market share is the ongoing competition from traditional horns, such as pneumatic and mechanical systems, which are still widely used in many vehicles. Traditional horns are often less expensive to manufacture, making them more attractive to cost-sensitive consumers and automakers, especially in markets where price remains a dominant factor.
Despite the energy efficiency and quieter operation of electric motor horns, the familiarity, lower cost, and established presence of traditional horns create significant barriers to widespread adoption. Moreover, the existing infrastructure and integration of mechanical horns in older vehicles make it more challenging for electric motor horns to penetrate the market, particularly in developing regions with lower EV penetration.
Incorporating smart technologies into electric motor horns presents a significant market opportunity. Smart features, such as remote control, customizable sound settings, and integration with vehicle systems, enhance user experience and safety.
This horn is compatible with a wide range of vehicles, from hatchbacks to luxury cars, showcasing the versatility and innovation in the sector. Such advancements align with growing consumer expectations for high-performance, tech-enabled automotive components, offering an opportunity for manufacturers to integrate more customizable solutions into electric motor horns, meeting both consumer demands and regulatory standards for noise reduction.

The global electric motor horn market is bifurcated into product, sound pressure/volume, end-use vehicle, and sales channel.
The flat type dominates the market due to its compact design and versatility. This horn type is commonly used in passenger cars and light commercial vehicles (LCVs), where space efficiency is a critical consideration. Its design ensures consistent performance, producing a loud, clear sound that meets regulatory standards. The flat type is cost-effective to manufacture and widely adopted by original equipment manufacturers (OEMs), contributing significantly to the OEM segment. The demand for this horn type is expected to grow as automotive manufacturers prioritize space-saving features and improved acoustic technologies.
The "Up-to 110 dB" segment is the dominant player due to its balance of sound output and regulatory compliance. Most passenger vehicles, LCVs, and smaller commercial vehicles favor this sound pressure range as it ensures sufficient audibility while adhering to noise regulations in urban areas. Its widespread use across OEMs, especially in compact vehicles, contributes to its market growth. As stricter noise regulations are enforced globally, manufacturers are opting for horns that provide a non-intrusive but effective sound profile, ensuring safety without contributing excessively to noise pollution.
Passenger cars lead the market segment due to the large volume of vehicle sales and the growing demand for electric and hybrid vehicles. With an increasing emphasis on safety and driver awareness, electric motor horns are becoming standard equipment in passenger vehicles. These horns are designed to be louder and more efficient, with manufacturers integrating them into the vehicle's overall acoustic system. Additionally, passenger car manufacturers focus on reducing noise pollution, leading to innovations in quieter but effective horn technologies that adhere to international standards, strengthening the passenger car segment.
The OEM segment leads the electric motor horn market as automakers continue to integrate advanced horn systems into new vehicles during the manufacturing process. OEMs prefer establishing long-term relationships with suppliers who can meet the technical and regulatory requirements for sound output, durability, and integration into various vehicle models. With technological advancements, OEMs are focusing on high-quality horns that improve vehicle safety and customer satisfaction. The continued shift towards electric vehicles (EVs) also boosts the demand for electric motor horns from OEMs, as these vehicles require horns that align with their design and sustainability goals.
Based on region, the global electric motor horn market is bifurcated into North America, Europe, Asia-Pacific, Latin America, and the Middle East and Africa.
Asia-Pacific presents a significant opportunity for the growth of the global market, driven by the rapid expansion of the automotive industry, particularly in EVs. With China and India leading the charge, the region is poised to become a major player in the EV market.
A notable example is the collaboration between South Korean automotive giant Hyundai and Indian component manufacturer Minda Industries. In 2024, Hyundai introduced its first all-electric SUV, the Ioniq 5, equipped with electric motor horns developed by Minda, a leader in automotive parts. The horn system offers reduced noise pollution, which aligns with urban regulations on noise control, particularly in densely populated areas.
As urbanization increases and environmental concerns grow in countries like Japan, South Korea, and India, there is a rising preference for quiet, energy-efficient vehicle components. The shift toward electric vehicles, supported by both consumer demand and government policies, creates an ideal environment for electric motor horn adoption, with significant growth expected in the next few years across the Asia-Pacific region.
