Choose a speaker-focused tool

The FixMySpeaker.now directory brings together speaker-focused tools for cleaning-oriented playback, device checks, channel comparisons, frequency tests and sweeps. These are focused starting points for practical tasks, not independent diagnostic instruments. Many pages share a playback engine while presenting different initial settings, ranges or controls. Choose the page that matches the speaker and symptom you want to investigate. Instrument tuners and vocal practice utilities are not part of this directory.

Use category filters to narrow the directory to Cleaning, Devices, Tablets, Channels, Frequency or Sweeps. Search by the visible tool name or description when you already know the task. If a search produces no matches, shorten the phrase or return to All. A missing search result does not necessarily mean that the underlying frequency or channel control is unavailable elsewhere.

Every tool should be approached as a controlled listening aid. It can produce a known signal, but it does not inspect your hardware, measure the room, record a microphone, certify a speaker's performance, or repair damaged electronics. A useful result is a specific observation that helps you decide what to check next.

• Cleaning: surface-moisture playback and safe exterior-care guidance.

• Devices: phone, computer and home speaker checks.

• Tablets: iPad, Android tablet and Samsung Galaxy Tab speaker checks.

• Channels: left, right and stereo comparisons.

• Frequency: fixed tones and adjustable speaker signals.

• Sweeps: brief comparisons across a frequency range.

Set up a safe, repeatable listening check

Select the intended output before starting. Lower both website and system volume, then begin with a brief signal at a comfortable level. A percentage on a slider is not a calibrated measure of loudness: headphones, amplifiers, interfaces, and speakers respond differently. Keep the playback control easy to reach and stop before making a major routing or equipment change.

Change one variable at a time. Keep the same frequency and level while comparing left with right, or keep the same output while comparing browsers. Record the settings that produced the symptom rather than running broad tests repeatedly. Finish with familiar speech or music to determine whether the observation also matters during normal use.

Never increase an inaudible signal aggressively. A speaker may be unable to reproduce deep bass, and a high-frequency signal may fall outside your hearing or the device's output capability. Inaudibility does not establish that no energy is being delivered. Stop for discomfort, harsh distortion, unusual mechanical noise, heat, or any concern about the equipment.

• Confirm output, begin quietly, and keep tests brief.

• Stop playback before reconnecting hardware or changing outputs.

• Avoid headphones for cleaning-oriented tones and never wear wet earbuds for a test.

• Do not use these tools as hearing tests or maximum-output challenges.

Cleaning tools: Water Eject and Dust Cleaner

Water Eject, at /, starts from a 165 Hz cleaning-oriented signal. Speaker movement may help shift some surface droplets in a suitable device, but that frequency is not a universal treatment. A clearer sound afterward does not prove that internal electronics are dry, that corrosion has stopped, or that charging is safe. Follow the model's liquid-exposure instructions before operating it.

Dust Cleaner, at Čištění prachu, uses a sweep-oriented starting point for listening and possible movement of loose surface material. It cannot reliably remove compacted lint, wax, grease, adhesive, or contamination behind a grille. Do not interpret a buzzing sweep as evidence that debris is being removed. Exterior cleaning should use only methods approved for the particular device.

Neither cleaning tool justifies maximum volume, extended unattended sessions, heat, compressed air, sharp objects, or pouring liquid into openings. If a spill involved salt, chlorine, or sugar, sound does not remove the residue. Persistent muffling after appropriate drying or gentle approved cleaning needs further assessment rather than progressively louder playback.

• Water Eject: /.

• Dust Cleaner: Čištění prachu.

• Use only when operating the device is consistent with manufacturer guidance.

• Treat any improvement as a listening observation, not a safety certificate.

Core channel checks for speakers, headphones, and earbuds

Speaker Test at Test reproduktoru is the general starting point for comparing left, right, and combined output. Headphone Test at Test sluchátek frames the same type of comparison around earcups and headphone routing. Stereo Test at Test sterea helps establish whether separate channel selections are being preserved through the selected playback path.

Left Speaker Test at Test levého reproduktoru and Right Speaker Test at Test pravého reproduktoru begin with the named channel selected. They are convenient when investigating a missing side, but they do not identify which physical driver a phone manufacturer has assigned to that channel. Mono audio, spatial processing, accessibility balance, and speaker virtualization can alter what you hear.

Earbud Test at Test špuntových sluchátek is useful after the earbuds are dry, charged, and appropriately paired. Compare both sides at a low level with the same signal. Fit, ear tips, mesh condition, and device settings can all affect perceived balance. Do not conclude that a quieter side needs a stronger tone or that equal output establishes safe battery condition.

• Headphone Test: Test sluchátek.

• Stereo Test: Test sterea.

• Left Speaker Test: Test levého reproduktoru.

• Right Speaker Test: Test pravého reproduktoru.

Channel checks for specific output paths

Laptop Audio Test at Test zvuku notebooku provides a starting point for built-in laptop output without requiring deep-bass stress. Phone Audio Test at Test zvuku telefonu supports similar listening comparisons on phones, where top and bottom speakers may differ by design. Physical symmetry should not be assumed from a left-right label.

Bluetooth Audio Test at Test zvuku Bluetooth plays through the Bluetooth destination selected by the operating system. It does not automatically diagnose pairing faults, codec behavior, or latency. USB Audio Test at Test zvuku USB likewise checks the selected playback route rather than every hardware channel on an interface.

HDMI Audio Test at Test zvuku HDMI helps confirm that sound reaches a selected television, monitor, or receiver. It is not a discrete surround-channel certification tool. If the display has no speakers, is muted, or forwards audio elsewhere, a silent result needs routing investigation rather than an assumption that the browser generated no signal.

• Bluetooth Audio Test: Test zvuku Bluetooth.

• USB Audio Test: Test zvuku USB.

• HDMI Audio Test: Test zvuku HDMI.

Frequency generators and waveform comparisons

Tone Generator at Generátor tónů and Frequency Generator at Generátor frekvencí provide broad frequency selection for controlled listening. Sine Wave Generator at Generátor sinusových vln starts with a comparatively simple single-frequency signal. Use it when you want to compare a particular pitch without intentionally adding the harmonic character of another waveform.

Square Wave Generator at Generátor obdélníkových vln, Triangle Wave Generator at Generátor trojúhelníkových vln, and Sawtooth Generator at Generátor pilových vln offer different timbres. Square and sawtooth signals contain substantial harmonic content; triangle waves also contain harmonics, with a different balance. These are not interchangeable signals merely because the displayed fundamental frequency is the same.

Lower the level before changing waveform. A brighter or harsher sound can be a normal property of the signal rather than a fault in the speaker. Conversely, the presence of expected harmonics does not excuse painful playback or mechanical rattling. Browser synthesis and the playback chain also limit how any idealized waveform is represented physically.

Focused frequency tests and reference tones

Bass Test at Test basů and Sub-bass Test at Test subbasů focus on lower frequencies for suitable equipment. Midrange Test at Test středních frekvencí and Treble Test at Test výšek help isolate broader listening regions. Small phone and laptop speakers are not expected to reproduce every low-frequency selection at a useful level.

Crossover Tone Test at Test tónu dělicí frekvence can support comparisons around a system's crossover region, but it does not automatically measure crossover alignment. Speaker Rattle Test at Test drnčení reproduktoru can help locate a repeatable noise; Low-volume Audio Test at Test zvuku při nízké hlasitosti encourages comparison without using loudness as the diagnostic method.

The 440 Hz Reference at Referenční tón 440 Hz, 1 kHz Reference at Referenční tón 1 kHz, and 165 Hz Reference at Referenční tón 165 Hz provide convenient known starting points. A reference frequency is not a calibrated acoustic level, and 165 Hz is not a universal cleaning or repair frequency. Write down the selected signal when comparing results.

Sweeps for finding changes across a range

Subwoofer Test at Test subwooferu and Frequency Sweep at Plynulé přelaďování frekvencí move through frequency ranges so you can notice where a buzz, drop, or change appears. Bass Sweep at Plynulé přelaďování basů, Midrange Sweep at Plynulé přelaďování středních frekvencí, and Treble Sweep at Plynulé přelaďování výšek narrow that process to a more relevant region.

Headphone Sweep at Frekvenční průběh sluchátek, Phone Speaker Sweep at Frekvenční průběh reproduktoru telefonu, and Desktop Speaker Sweep at Frekvenční průběh stolních reproduktorů provide device-oriented starting points. Their names do not mean the website knows the connected device or has verified its safe limits. Review the range and begin at low output.

Crossover Sweep at Přelaďování kolem dělicí frekvence can reveal a change worth investigating around a crossover region. Pulse Tone Test at Test pulzního tónu and Bass Pulse Test at Test basových pulzů provide interrupted playback comparisons within the Sweeps directory category. Neither sweep loudness nor pulsed output produces a calibrated frequency-response chart. Rooms, processing, hearing, and placement all influence impressions.

Device-specific speaker starting points

The device category brings speaker checks together by the equipment you are using. iPhone, Samsung and Pixel checks begin with moderate frequencies for short comparisons. These names do not mean the browser detects your model or knows which physical grille carries the left channel. Confirm the intended output and consult the device specifications before interpreting differences between openings.

Soundbar, TV, monitor, bookshelf, floorstanding, portable and smart speaker checks offer convenient starting signals for those playback paths. Select the destination in your operating system first. An HDMI display without built-in speakers will not play sound merely because you opened its tool. A smart speaker must already support the selected streaming or Bluetooth connection; the page cannot pair it or change its network settings automatically.

Use Speaker Balance Test for left-right comparisons, Speaker Buzz Check for a repeatable low-level noise, and Speaker Dialogue Range Test to explore the region important to speech. The dialogue tool produces tones, not spoken words, so confirm any impression with familiar dialogue afterward. Woofer and tweeter checks isolate appropriate frequency regions but do not electrically separate drivers inside a connected cabinet. Stop if a signal sounds strained or uncomfortable.

For tablets, choose the Test reproduktoru iPad, Test reproduktoru tabletu or Test reproduktoru tabletu Samsung. Check media volume, application mute and Bluetooth output first. Missing alerts and missing media can have different causes: a notification setting may silence an alert while music still plays normally. Compare a familiar clip in more than one application before deciding that a tablet speaker needs repair.

• Phones: Test reproduktoru iPhone, Test reproduktoru Samsung and Test reproduktoru Pixel.

• Displays: Test reproduktorů soundbaru, Test reproduktorů TV and Test reproduktorů monitoru.

• Cabinets: Test regálových reproduktorů and Test sloupových reproduktorů.

• Focused checks: Kontrola bzučení reproduktoru and Test řečového pásma reproduktoru.

Turn an observation into a sensible next step

A useful test ends with a narrower question. If one channel is silent only on a Bluetooth route, investigate that route. If a rattle occurs with several sources at a modest level, check the surroundings and consider hardware support. If only one recording sounds distorted, assess the recording before cleaning or repairing the speaker.

Use the blog directory for the next safe reading step and the contact page for website-specific problems. Preserve the route, output, frequency, and settings that produced the observation. Do not keep repeating tones once the result is clear. The directory is most useful when it reduces unnecessary experimentation rather than encouraging a longer or louder session.

• Separate source, routing, settings, environment, and hardware possibilities.

• Compare with ordinary media before drawing a broad conclusion.

• Stop when further playback is unsafe or no longer informative.

• Escalate persistent faults with a concise history of safe checks.
