Thanks, Mike. Thanks to all of you for joining us today. To briefly recap, we've reported Q1 results with revenue of $273 million, gross margins of 32.6% and operating margins of 11.7%. We were pleased to deliver revenue above the high end of our Analyst Day projections, driven by both of our segments. Operating income was within the range of our expectations, and better-than-expected revenue was partially offset by discrete SG&A expenses.
Now let me provide an overview of the trends we saw in our segments and end markets, discuss some of our new innovative solutions that will enable our future growth. After that, John will provide financial highlights for Q1 and our guidance for Q2. In our Mobile Consumer Electronics segment, Q1 revenue decreased by 3% from a year ago, well ahead of our prior expectation. We saw stronger sales in Q1, driven by North American OEM. In this segment, growth from a year ago, excluding BlackBerry and Nokia, would have been up 12% year-over-year.
Revenue for Mobile Consumer Electronics comprised approximately 60% of total sales compared to 61% in the year-ago period. Note that about 3/4 of the revenue comes from the handset market, with the remainder coming from tablets, laptops and other consumer devices. As we look forward, we're well positioned with design wins on major OEM product launches planned for the second half of this year.
In addition, there are several trends we are continuing to see in the mobile consumer space, which we believe will drive growth in the second half of '14 and beyond. Generally speaking, consumers around the world are demanding improved acoustics from their devices, regardless of the country they live and/or the type of device they're using. Whether it's for improved voice quality in a call, a better experience when watching movie or listening to music or enhanced audio capture when recording a home movie, consumers want better performance.
To satisfy these demands, the general trend is for acoustic dollar content to increase across consumer electronic devices for 2 primary reasons. First, most of the solutions we are introducing are higher performance and command higher value. Second, many OEMs are increasing the number of acoustic components per device. As an example, over the last -- the past several years, we have seen an increase in the number of microphones used in numerous devices, particularly in smartphone. The benefit to the user are substantial, including reduced background noise, improved voice recognition, better hands-free communication and enhanced audio recording and playback capabilities. For OEMs, acoustics can truly help differentiate their products in the marketplace.
We believe an additional opportunity exists with these audio trends proliferating to midrange phones and tablets, as well as the emerging wearables market. Knowles can capitalize on these market demands by leveraging our acoustics expertise, proprietary process technologies and entrenched engineering relationships to deliver solutions that improve the performance of the consumers' devices. Given Knowles' long-standing technology leadership in the acoustics market and significant scale, we continue to garner content across key mobile phone, tablet and other consumer platforms.
Over the past several months, we've talked a lot about product innovation and how critical it is for Knowles' long-term success. We are constantly introducing new products in all areas of our business. As an example, we recently released -- shipped 30 million units, in Q1, of the world's first digital multimode microphone, which features 3X lower power consumption relative to other digital microphones and performance matching to enable longer battery life and always-on listening functionality.
I want to spend a moment to highlight one other area of innovation we are particularly excited about, which is our Integrated Audio Solution technology. This solution is a highly customized module that improves speaker quality and customer time to market. Consumers that use our solutions benefit from superior acoustics and ease of implementation using a space-efficient module. The level of integration we provide allows us to increase our content while providing higher-performance solutions for our customers. These products have been well received, and we shipped approximately 2 million units to a leading Chinese smartphone OEM in Q1.
In addition, this dedicated team has numerous other integrated designs in development that leverage our broad acoustic product portfolio and years of experience in manufacturing industry-leading solutions. We'll discuss more about these opportunities later in the year as they become available in the market. Overall, the trends in our Mobile Consumer Electronics market are positioned with new products [indiscernible] are expected to drive growth for 2014.
In the Specialty Components segment, Q1 sales were up 3% from a year ago and represented about 40% of the total company revenue. The growth was slightly better than our Analyst Day projections. Strength was primarily driven by sales in Precision Devices, fueled by improved communication infrastructure spending as 4G/LTE rollouts are beginning in China and continuing in other regions. We remain focused on securing design wins with solutions that enables high-performance mission-critical applications in the wireless infrastructure, medical, military and aerospace end markets. We are able to quickly deliver solutions for our customers' applications because of our specific knowledge of their systems and our leadership in crystal oscillator and capacitor technologies.
Within our acoustic component business, we continue to be the leader of all top hearing aid manufacturers. Our latest technology is integral to some very exciting new products like GN ReSound's LiNX product, that is the first hearing aid certified for Apple's Made For iPhone program. We are also seeing continued adoption of our MEMs solutions in the hearing aid market and expect MEMs penetration to continue over the next several years. As the global leader in MEMs microphone technology, we are uniquely positioned in this market. Overall growth in this market is stable, and we expect favorable macro trends, like the world's aging population and emerging markets, to support steady, long-term growth in the years to come.
As discussed, both of our segments will also benefit from our continuing effort to optimize our global manufacturing footprint. Our previously announced restructurings of our capacitor and hearing health businesses are on track. In addition, we recently announced the closure and transfer of our Vienna manufacturing operations, which primarily supported BlackBerry and Nokia. This is expected to drive significant margin expansion beginning in Q4.
With that, I'll turn it over to John to expand on our financial results and provide our guidance for the June quarter. John?
